Configure the server firewall. Enable the firewall: # systemctl enable firewalld # systemctl start firewalld. Enable in your firewall the FTP port and port. I have set VNC up on Redhat EL5 once and it worked. command "service vncserver start" it responds that there are no displays to start. Enter the VNC password that we have set in above step, after validating the authentication. Remote Desktop session will start. From Windows.

Example In the example above, display number 3 and the user joe are set. Do not use 0 as the display number since the main X display of a workstation is usually indicated as 0. Table See the Xvnc 1 man page for further options.
The stored password is not encrypted; anyone who has access to the password file can find the plain-text password. Starting VNC Server. In order to start a VNC desktop, the vncserver utility is used. It is a Perl script which simplifies the process of starting an Xvnc server. There are three ways to start vncserver :.
You can allow vncserver to choose the first available display number, start Xvnc with that display number, and start the default window manager in the Xvnc session. You can enable the vncserver service automatically at system start.
Every time you log in, vncserver is automatically started. Disables installation of the Core package group which is otherwise always installed by default. Disabling the Core package group with --nocore should be only used for creating lightweight containers; installing a desktop or server system with --nocore will result in an unusable system.
The options in this list only apply to a single package group. Note that some package groups, such as Scientific Support , do not have any mandatory or default packages specified - only optional packages. In this case the --optional option must always be used, otherwise no packages from this group will be installed. The --nodefaults and --optional options cannot be used together.
You can install only mandatory packages during the installation using --nodefaults and install the optional packages on the installed system post installation. It is also possible to run scripts, using interpreters available in the installation environment. However, the name service has not been configured at this point, so only IP addresses work, not URLs.
The following options can be used to change the behavior of pre-installation scripts. Allows you to specify a different scripting language, such as Python. Note that the platform-python interpreter uses Python version 3. Additionally, platform-python is meant for system tools: Use the python36 package outside the installation environment.
The commands in the pre-install script are run after the following tasks are complete:. Note: The pre-install script does not run in chroot environment. The following options can be used to change the behavior of pre-install scripts. They are evaluated in their order of appearance in the Kickstart file. You can use this section to run tasks such as system subscription. You have the option of adding commands to run on the system once the installation is complete, but before the system is rebooted for the first time.
The post-install script is run in a chroot environment, therefore, performing tasks such as copying scripts or RPM packages from the installation media do not work by default. You can change this behavior using the --nochroot option as described below. Because post-install script runs in a chroot environment, most systemctl commands will refuse to perform any action.
The following options can be used to change the behavior of post-installation scripts. Allows you to specify commands that you would like to run outside of the chroot environment. Note that the path of the log file must take into account whether or not you use the --nochroot option. For example, without --nochroot :. Note that NFS file locking is not supported while in Kickstart mode, therefore the -o nolock option is required. One of the most common uses of post-installation scripts in Kickstart installations is automatic registration of the installed system using Red Hat Subscription Manager.
This script can also be used to assign or attach subscriptions automatically to the system that best-match that system. When registering to Satellite 6 or CloudForms System Engine, you may also need to specify more subscription-manager options like --serverurl , --org , --environment as well as credentials provided by your local administrator.
Note that credentials in the form of an --org --activationkey combination is a good way to avoid exposing --username --password values in shared kickstart files. Additional options can be used with the registration command to set a preferred service level for the system and to restrict updates and errata to a specific minor release version of RHEL for customers with Extended Update Support subscriptions that need to stay fixed on an older stream.
See also the How do I use subscription-manager in a kickstart file? This section controls the behavior of the user interface of the installation system. Starting with Red Hat Enterprise Linux 7, Kickstart installations can contain custom scripts which are run when the installation program encounters a fatal error. For example, an error in a package that has been requested for installation, failure to start VNC when specified, or an error when scanning storage devices.
Installation cannot continue after such an error has occured. These add-ons can expand the basic Kickstart and Anaconda functionality in many ways. For example, if you want to use the Kdump add-on, which is distributed with Anaconda by default, use the following commands:. This reference is a complete list of all Kickstart commands supported by the Red Hat Enterprise Linux installation program program. The commands are sorted alphabetically in a few broad categories.
If a command can fall under multiple categories, it is listed in all of them. The following sections describe the changes in Kickstart commands and options in Red Hat Enterprise Linux 8. The auth or authconfig Kickstart command is deprecated in Red Hat Enterprise Linux 8 because the authconfig tool and package have been removed.
Similarly to authconfig commands issued on command line, authconfig commands in Kickstart scripts now use the authselect-compat tool to run the new authselect tool. For a description of this compatibility layer and its known issues, see the manual page authselect-migration 7. The installation program will automatically detect use of the deprecated commands and install on the system the authselect-compat package to provide the compatibility layer.
Where only specific options are listed, the base command and its other options are still available and not deprecated. Except the auth or authconfig command, using the commands in Kickstart files prints a warning in the logs.
You can turn the deprecated command warnings into errors with the inst. The following Kickstart commands and options have been completely removed in Red Hat Enterprise Linux 8. Using them in Kickstart files will cause an error. Where only specific options and values are listed, the base command and its other options are still available and not removed.
The Kickstart commands in this list control the mode and course of installation, and what happens at its end. The cdrom Kickstart command is optional. It performs the installation from the first optical drive on the system. The cmdline Kickstart command is optional. It performs the installation in a completely non-interactive command line mode.
Any prompt for interaction halts the installation. The driverdisk Kickstart command is optional. Use it to provide additional drivers to the installation program. Driver disks can be used during Kickstart installations to provide additional drivers not included by default. Then, you must use the driverdisk command to specify that the installation program should look for a driver disk and its location. Examples include:. Driver disks can also be loaded from a hard disk drive or a similar device instead of being loaded over the network or from initrd.
Follow this procedure:. Replace DD with a specific label and replace e Use anything supported by the inst. The eula Kickstart command is optional. Specifying this option prevents Initial Setup from prompting you to accept the license agreement after you finish the installation and reboot the system for the first time. The firstboot Kickstart command is optional. It determines whether the Initial Setup application starts the first time the system is booted.
If enabled, the initial-setup package must be installed. If not specified, this option is disabled by default. The graphical Kickstart command is optional. It performs the installation in graphical mode. This is the default. Halt the system after the installation has successfully completed. This is similar to a manual installation, where Anaconda displays a message and waits for the user to press a key before rebooting. During a Kickstart installation, if no completion method is specified, this option is used as the default.
The harddrive Kickstart command is optional. It performs the installation from a Red Hat installation tree or full installation ISO image on a local drive. The drive must be formatted with a file system the installation program can mount: ext2 , ext3 , ext4 , vfat , or xfs. Use its methods as separate commands. The install Kickstart command is optional. It specifies the default installation mode. The liveimg Kickstart command is optional.
It performs the installation from a disk image instead of packages. The logging Kickstart command is optional. It controls the error logging of Anaconda during installation. It has no effect on the installed system. Logging is supported over TCP only. The default port is The mediacheck Kickstart command is optional. This command forces the installation program to perform a media check before starting the installation.
This command requires that installations be attended, so it is disabled by default. The nfs Kickstart command is optional. It performs the installation from a specified NFS server. The ostreesetup Kickstart command is optional. It is used to set up OStree-based installations. The poweroff Kickstart command is optional. It shuts down and powers off the system after the installation has successfully completed.
Normally during a manual installation, Anaconda displays a message and waits for the user to press a key before rebooting. The reboot Kickstart command is optional. It instructs the installation program to reboot after the installation is successfully completed no arguments. Normally, Kickstart displays a message and waits for the user to press a key before rebooting.
When kexec is used, device registers which would normally be cleared during a full system reboot might stay filled with data, which could potentially create issues for some device drivers. The rhsm Kickstart command is optional. The shutdown Kickstart command is optional. It shuts down the system after the installation has successfully completed. During the installation, you can interact with the installation program and monitor its progress over an SSH connection.
Use the sshpw command to create temporary accounts through which to log on. Each instance of the command creates a separate account that exists only in the installation environment. These accounts are not transferred to the installed system. This option is mutually exclusive with --plaintext. To create an encrypted password, you can use Python:. This generates a sha crypt-compatible hash of your password using a random salt. If you want to disable root ssh access, while allowing another user ssh access, use the following:.
To simply disable root ssh access, use the following:. The text Kickstart command is optional. It performs the Kickstart installation in text mode. Kickstart installations are performed in graphical mode by default. The url Kickstart command is optional. You can only specify one URL. The vnc Kickstart command is optional. It allows the graphical installation to be viewed remotely through VNC. This method is usually preferred over text mode, as there are some size and language limitations in text installations.
With no additional options, this command starts a VNC server on the installation system with no password and displays the details required to connect to it. The Kickstart commands in this list configure further details on the resulting system such as users, repositories, or services.
Use the new authselect command instead of the deprecated auth or authconfig Kickstart command. The auth or authconfig Kickstart command is optional. It sets up the authentication options for the system using the authconfig tool, which can also be run on the command line after the installation finishes.
The authselect Kickstart command is optional. It sets up the authentication options for the system using the authselect command, which can also be run on the command line after the installation finishes. The firewall Kickstart command is optional. It specifies the firewall configuration for the installed system.
Some services like cups , avahi , and so on. Valid options are anything recognized by the firewall-offline-cmd program in the firewalld package. If the firewalld service is running, firewall-cmd --get-services provides a list of known service names. The group Kickstart command is optional. It creates a new user group on the system. The keyboard Kickstart command is required. It sets one or more available keyboard layouts for the system. Accepts values in the same format as setxkbmap 1 , either in the layout format such as cz , or in the layout variant format such as cz qwerty.
All available layouts can be viewed on the xkeyboard-config 7 man page under Layouts. Multiple options must be separated by commas without spaces. Accepts values in the same format as setxkbmap 1. Available switching options can be viewed on the xkeyboard-config 7 man page under Options.
The lang Kickstart command is required. It sets the language to use during installation and the default language to use on the installed system. Takes the form of comma-separated list without spaces. The module Kickstart command is optional.
Use this command to enable a package module stream within kickstart script. Specifies the name of the module stream to enable. You do not need to specify this option for modules with a default stream defined. For modules without a default stream, this option is mandatory and leaving it out results in an error.
Enabling a module multiple times with different streams is not possible. The repo Kickstart command is optional. It configures additional yum repositories that can be used as sources for package installation. You can add multiple repo lines. These options are mutually exclusive and optional. The variables that can be used in yum repository configuration files are not supported here.
The rootpw Kickstart command is required. To create an encrypted password, you can use python:. The selinux Kickstart command is optional. It sets the state of SELinux on the installed system. The default SELinux policy is enforcing. The services Kickstart command is optional. It modifies the default set of services that will run under the default systemd target.
The list of disabled services is processed before the list of enabled services. Therefore, if a service appears on both lists, it will be enabled. Do not include spaces in the list of services. If you do, Kickstart will enable or disable only the services up to the first space.
That disables only the auditd service. To disable all four services, this entry must include no spaces:. The skipx Kickstart command is optional. If present, X is not configured on the installed system. If you install a display manager among your package selection options, this package creates an X configuration, and the installed system defaults to graphical. That overrides the effect of the skipx option. The sshkey Kickstart command is optional. The syspurpose Kickstart command is optional.
Use it to set the system purpose which describes how the system will be used after installation. This information helps apply the correct subscription entitlement to the system. Available values are:. The timezone Kickstart command is required. It sets the system time zone. In Red Hat Enterprise Linux 8, time zone names are validated using the pytz. In previous releases, the names were validated against pytz.
Note that the graphical and text mode interfaces still use the more restricted pytz. The user Kickstart command is optional. It creates a new user on the system. Consider using the --uid and --gid options to set IDs of regular users and their default groups at range starting at instead of That is because the range reserved for system users and groups, 0 - , might increase in the future and thus overlap with IDs of regular users.
For changing the minimum UID and GID limits after the installation, which ensures that your chosen UID and GID ranges are applied automatically on user creation, see the Setting default permissions for new files using umask section of the Configuring basic system settings document. Files and directories are created with various permissions, dictated by the application used to create the file or directory.
For example, the mkdir command creates directories with all permissions enabled. However, applications are prevented from granting certain permissions to newly created files, as specified by the user file-creation mask setting. The user file-creation mask can be controlled with the umask command.
If unset, it defaults to This means that by default when an application creates a file, it is prevented from granting write permission to users other than the owner of the file. However, this can be overridden by other settings or scripts. More information can be found in the Setting default permissions for new files using umask section of the Configuring basic system settings document. The xconfig Kickstart command is optional. It configures the X Window System.
The Kickstart commands in this list let you configure networking on the system. Use the optional network Kickstart command to configure network information for the target system and activate the network devices in the installation environment. The device specified in the first network command is activated automatically. You can also explicitly require a device to be activated using the --activate option.
If you use the --activate option on a device that has already been activated for example, an interface you configured with boot options so that the system could retrieve the Kickstart file the device is reactivated to use the details specified in the Kickstart file. Use the --nodefroute option to prevent the device from using the default route. By default, Anaconda activates the first network device in the Kickstart file regardless of the --activate option.
You can disable the default setting by using the --no-activate option. The default option is dhcp ; the dhcp and bootp options are treated the same. To disable ipv4 configuration of the device, use --noipv4 option. This option configures ipv4 configuration of the device. For ipv6 configuration use --ipv6 and --ipv6gateway options. To direct a system to use DHCP:. To direct a machine to use BOOTP to obtain its networking configuration, use the following line in the Kickstart file:.
The static method requires that you specify at least the IP address and netmask in the Kickstart file. This information is static and is used during and after the installation. You can also configure multiple nameservers at the same time. Make sure you specify this option for any network command beyond the first.
The host name can either be a fully qualified domain name FQDN in the format hostname. If you use a Dynamic Host Configuration Protocol DHCP service to automatically assign a domain name to connected systems, only specify the short host name. If you provide additional options when configuring the host name, the network command configures a device using the options specified.
If you do not specify which device to configure using the --device option, the default --device link value is used. Additionally, if you do not specify the protocol using the --bootproto option, the device is configured to use DHCP by default. The above command creates a bond device named bond0 using the em1 and em2 interfaces as its secondary devices.
If an option itself contains a comma, use a semicolon to separate the options. For the list of available and supported modes, see Configuring and Managing Networking Guide. The interface name can be arbitrary for example, my-vlan , but in specific cases, the following conventions must be followed:.
Secondary devices are separated by commas. Available values are stp , priority , forward-delay , hello-time , max-age , and ageing-time. For information about these parameters, see the bridge setting table in the nm-settings 5 man page or at Network Configuration Setting Specification. Also see the Configuring and managing networking document for general information about network bridging.
The realm Kickstart command is optional. For more information about this command, see the join section of the realm 8 man page. The Kickstart commands in this section configure aspects of storage such as devices, disks, partitions, LVM, and filesystems. The device Kickstart command is optional. Use it to load additional kernel modules. However, on older systems and some PCI systems, Kickstart requires a hint to find the proper devices.
The device command, which tells the installation program to install extra modules, uses the following format:. The autopart Kickstart command is optional. It automatically creates partitions. Accepts the following values:. For a description of the available partition schemes, see Section C. This is equivalent to checking the Encrypt partitions check box on the initial partitioning screen during a manual graphical installation.
When encrypting one or more partitions, Anaconda attempts to gather bits of entropy to ensure the partitions are encrypted securely. Gathering entropy can take some time - the process will stop after a maximum of 10 minutes, regardless of whether sufficient entropy has been gathered.
The process can be sped up by interacting with the installation system typing on the keyboard or moving the mouse. If you are installing in a virtual machine, you can also attach a virtio-rng device a virtual random number generator to the guest. The bootloader Kickstart command is required. It specifies how the boot loader should be installed. To specify multiple parameters, separate them with spaces.
To disable this behavior, explicitly disallow installation of plymouth :. This option is useful for disabling mechanisms which were implemented to mitigate the Meltdown and Spectre speculative execution vulnerabilities found in most modern processors CVE, CVE, and CVE In some cases, these mechanisms may be unnecessary, and keeping them enabled causes decreased performance with no improvement in security.
Ensure your system is not at risk of attack before disabling any of the vulnerability mitigation mechanisms. See the Red Hat vulnerability response article for information about the Meltdown and Spectre vulnerabilities. When zipl is installed, it determines the boot drive on its own. Valid values are the following:. On a GPT-formatted disk, this option installs stage 1. On an MBR-formatted disk, stage 1. This should be used to restrict access to the GRUB2 shell, where arbitrary kernel options can be passed.
If a password is specified, GRUB2 also asks for a user name. The user name is always root. If you want to encrypt the password, use this option and an encrypted password. An example bootloader Kickstart entry with an encrypted password looks similar to the following:. For example, instead of:. This way the command will always target the same storage device. This is especially useful in large storage environments. See the chapter Overview of persistent naming attributes in the Managing storage devices document for more in-depth information about different ways to consistently refer to storage devices.
The zipl Kickstart command is optional. When installed on a system that is later than IBM z14, the installed system cannot be booted from an IBM z14 or earlier model. Secure Boot is not supported on IBM z14 and earlier models. Use --no-secure-boot if you intend to boot the installed system on IBM z14 and earlier models. The clearpart Kickstart command is optional. It removes partitions from the system, prior to creation of new partitions.
By default, no partitions are removed. This option will erase all disks which can be reached by the installation program, including any attached network storage. For example, the following clears all the partitions on the first two drives on the primary IDE controller:. Never specify multipath devices by device names like mpatha. Device names such as this are not specific to a particular disk.
Therefore, the clearpart command could target the wrong disk. Because --initlabel can see all disks, it is important to ensure only those drives that are to be formatted are connected. This option overrides the --all and --linux options if used.
Can be used across different drives. The fcoe Kickstart command is optional. The ignoredisk Kickstart command is optional. It causes the installation program to ignore the specified disks. This is useful if you use automatic partitioning and want to be sure that some disks are ignored.
For example, without ignoredisk , attempting to deploy on a SAN-cluster the Kickstart would fail, as the installation program detects passive paths to the SAN that return no partition table. All other disks are ignored. For example, to use disk sda during installation and ignore all other disks:. You must specify only one of the --drives or --only-use.
The iscsi Kickstart command is optional. It specifies additional iSCSI storage to be attached during installation. The iscsiname Kickstart command is optional. It assigns a name to an iSCSI node specified by the iscsi command. The logvol Kickstart command is optional. The mount point where the partition is mounted. Must be of one of the following forms:. To determine the size of the swap partition automatically, use the --recommended option:. To determine the size of the swap partition automatically and also allow extra space for your system to hibernate, use the --hibernation option:.
The size assigned will be equivalent to the swap space assigned by --recommended plus the amount of RAM on your system. Specifies a free form string of options to be used when mounting the filesystem. The size of the logical volume, as a percentage of the free space in the volume group after any statically-sized logical volumes are taken into account. You cannot use both of these options on the same logical volume. If you do not specify a passphrase, the installation program uses the default, system-wide passphrase set with the autopart --passphrase command, or stops the installation and prompts you to provide a passphrase if no default is set.
Specify which mode should be used to cache this logical volume - either writeback or writethrough. For more information about cached logical volumes and their modes, see the lvmcache 7 man page. Do not use the dash - character in logical volume and volume group names when installing Red Hat Enterprise Linux using Kickstart. This limitation only applies to newly created logical volume and volume group names.
If you are reusing existing ones using the --noformat option, their names will not be changed. Create the partition first, create the logical volume group, and then create the logical volume:. The mount Kickstart command is optional. It assigns a mount point to an existing block device, and optionally reformats it to a given format. The nvdimm Kickstart command is optional. Additionally, the specified device is implicitly marked as to be used, so a subsequent nvdimm use command for the same device is redundant.
The device must be already configured to the sector mode by the nvdimm reconfigure command. The part or partition Kickstart command is required. It creates a partition on the system. The value must be of one of the following forms:.
The size assigned will be effective but not precisely calibrated for your system. To determine the size of the swap partition automatically but also allow extra space for your system to hibernate, use the --hibernation option:.
For the swap sizes assigned by these commands, see Section C. The partition is used for software RAID see raid. The partition is used for LVM see logvol. It is not necessary on UEFI systems. See also the bootloader command. It is not necessary on BIOS systems. Specify an integer value here such as do not include the unit. If the --size value is too small, the installation fails.
Set the --size value as the minimum amount of space you require. For size recommendations, see Section C. For systems that have less than 2 GB of physical memory, the imposed limit is twice the amount of physical memory.
For systems with more than 2 GB, the imposed limit is the size of physical memory plus 2GB. Uses an existing blank device and format it to the new specified type. These options can also add a partition to a logical volume. The device must already exist on the system; the --onpart option will not create it.
It is also possible to specify an entire drive, rather than a partition, in which case Anaconda will format and use the drive without creating a partition table. Note, however, that installation of GRUB2 is not supported on a device formatted in this way, and must be placed on a drive with a partition table.
This command always creates a partition. Forces the partition to be created on a particular disk. Therefore, the part command could target the wrong disk. For details about the recommended scheme, see Section C. If you do not specify a passphrase, Anaconda uses the default, system-wide passphrase set with the autopart --passphrase command, or stops the installation and prompts you to provide a passphrase if no default is set.
The raid Kickstart command is optional. It assembles a software RAID device. See Section C. Do not use mdraid names in the form of md0 - these names are not guaranteed to be persistent. Instead, use meaningful names such as root or swap. If you have an old v0.
It also creates three swap partitions, one on each drive. The reqpart Kickstart command is optional. It automatically creates partitions required by your hardware platform. The snapshot Kickstart command is optional. Use it to create LVM thin volume snapshots during the installation process. This enables you to back up a logical volume before or after the installation. To create multiple snapshots, add the snaphost Kickstart command multiple times.
The volgroup Kickstart command is optional. If you use this option, do not specify a partition. Create the partition first, then create the logical volume group, and then create the logical volume. The zerombr Kickstart command is optional. The zerombr initializes any invalid partition tables that are found on disks and destroys all of the contents of disks with invalid partition tables. This command is required when performing an installation on an bit IBM Z system with unformatted Direct Access Storage Device DASD disks, otherwise the unformatted disks are not formatted and used during the installation.
The zfcp Kickstart command is optional. It defines a Fibre channel device. This option only applies on bit IBM Z. All of the options described below must be specified. This command configures the kdump kernel crash dumping mechanism. The syntax for this command is unusual because it is an add-on rather than a built-in Kickstart command. In case of a system crash, kexec boots into a second kernel a capture kernel. This capture kernel resides in a reserved part of the system memory.
For more information about Kdump, see the Installing and configuring kdump chapter of the Managing, monitoring and updating the kernel document. You can also specify auto instead of a numeric value. In that case, the installation program will determine the amount of memory automatically based on the criteria described in the Memory requirements for kdump section of the Managing, monitoring and updating the kernel document. This add-on has been enabled by default since Red Hat Enterprise Linux 7.
When enabled, the packages necessary to provide this functionality will automatically be installed. However, by default, no policies are enforced, meaning that no checks are performed during or after installation unless specifically configured. Applying a security policy is not necessary on all systems. This command should only be used when a specific policy is mandated by your organization rules or government regulations. These pairs are whitespace-agnostic. Values can be optionally enclosed in single quotes ' or double quotes ".
Type of the security content. Possible values are datastream , archive , rpm , and scap-security-guide. If the content-type is scap-security-guide , the add-on will use content provided by the scap-security-guide package, which is present on the boot media. This means that all other keys except profile will have no effect. Example B. The following is a more complex example which loads a custom profile from a web server:.
The pwpolicy Kickstart command is optional. Use this command to enforce a custom password policy during installation. The policy requires you to create passwords for the root, users, or the luks user accounts. The factors such as password length and strength decide the validity of a password. The Kickstart command in this section repairs an installed system. The rescue Kickstart command is optional.
It provides a shell environment with root privileges and a set of system management tools to repair the installation and to troubleshoot the issues like:. The Kickstart rescue mode is different from the rescue mode and emergency mode, which are provided as part of the systemd and service manager. The rescue command does not modify the system on its own. You can choose not to mount the system, or to mount it in read-only mode.
To run a rescue mode, make a copy of the Kickstart file, and include the rescue command in it. Using the rescue command causes the installer to perform the following steps:. This step is run only if the installed system is mounted in read-write mode. This section describes the file systems available in Red Hat Enterprise Linux.
This small boot partition is located on the first partition of the hard drive. RAID stands for Redundant Array of Independent Disks, a technology which allows you to combine multiple physical disks into logical units. Some setups are designed to enhance performance at the cost of reliability, while others improve reliability at the cost of requiring more disks for the same amount of available space. Red Hat recommends that you create separate file systems at the following mount points. This partition scheme is recommended for bare metal deployments and it does not apply to virtual and cloud deployments.
Due to the limitations of most firmwares, creating a small partition to hold these is recommended. In most scenarios, a 1 GiB boot partition is adequate. The root directory is the top-level of the directory structure. While a 5 GiB root file system allows you to install a minimal installation, it is recommended to allocate at least 10 GiB so that you can install as many package groups as you want.
Swap file systems support virtual memory; data is written to a swap file system when there is not enough RAM to store the data your system is processing. Swap size is a function of system memory workload, not total system memory and therefore is not equal to the total system memory size. It is important to analyze what applications a system will be running and the load those applications will serve in order to determine the system memory workload.
Application providers and developers can provide guidance. When the system runs out of swap space, the kernel terminates processes as the system RAM memory is exhausted. Configuring too much swap space results in storage devices being allocated but idle and is a poor use of resources. Too much swap space can also hide memory leaks. The maximum size for a swap partition and other additional information can be found in the mkswap 8 manual page. The following table provides the recommended size of a swap partition depending on the amount of RAM in your system and if you want sufficient memory for your system to hibernate.
If you let the installation program partition your system automatically, the swap partition size is established using these guidelines. Automatic partitioning setup assumes hibernation is not in use. The maximum size of the swap partition is limited to 10 percent of the total size of the hard drive, and the installation program cannot create swap partitions more than 1TiB.
At the border between each range, for example, a system with 2 GiB, 8 GiB, or 64 GiB of system RAM, discretion can be exercised with regard to chosen swap space and hibernation support. If your system resources allow for it, increasing the swap space can lead to better performance.
Distributing swap space over multiple storage devices - particularly on systems with fast drives, controllers and interfaces - also improves swap space performance. Many systems have more partitions and volumes than the minimum required. Choose partitions based on your particular system needs. There is no best way to partition every system; the optimal setup depends on how you plan to use the system being installed.
However, the following tips may help you find the optimal layout for your needs:. When kdump is enabled in system it will take approximately another 40MB another initrd with 33MB. However, it is recommended that you increase the size of this partition if you are planning on retaining multiple kernel releases or errata kernels.
In some situations, such as when these directories are placed on an iSCSI drive or an FCoE location, the system may either be unable to boot, or it may hang with a Device is busy error when powering off or rebooting. It is important to understand how storage technologies are configured and how support for them may have changed between major versions of Red Hat Enterprise Linux.
Any RAID functions provided by the mainboard of your computer, or attached controller cards, need to be configured before you begin the installation process. On systems with more than one hard drive, you can use the Red Hat Enterprise Linux installation program to operate several of the drives as a Linux software RAID array.
