You can use both inst. In this scenario, the installation program attempts to load any available driver updates from the location and also prompts you to select a device that contains the driver update. If you load additional, separate drivers, verify that they are signed. You received the driver update ISO image from your hardware vendor, or a trusted third-party vendor. If only a single ISO image file ending in. Verify that a single file rhdd3 is available.
Once you have completed the prerequisite steps, the drivers are automatically loaded when the installation program starts, and installed on the system during the installation process. In this scenario, the installation program does not prompt you to select a driver update ISO image. From the boot menu window, press the Tab key on your keyboard to display the boot command line. Append the inst. Press c to install the selected driver. The selected driver is loaded and the installation process starts.
Press Enter to execute the boot process. The drivers available at the specified location are automatically loaded and the installation process starts. For more information about the inst.
See the lvm 8 man page for additional information. For more information about cached logical volumes and their modes, see the lvmcache 7 man page. Create the partition first, create the logical volume group, and then create the logical volume. If given, this command forces the installation program to perform a media check rd. This command requires that installations be attended, so it is disabled by default. Assigns a mount point to an existing block device, and optionally reformats it to a given format.
Unlike most other storage configuration commands in Kickstart, mount does not require you to describe the entire storage configuration in the Kickstart file. You only need to ensure that the described block device exists on the system. However, if you want to create the storage stack with all the devices mounted, you must use other commands such as part to do so. You can not use mount together with other storage-related commands such as part , logvol , or autopart in the same Kickstart file.
The list of arguments provided here is not processed, so they must be specified in a format that can be passed directly to the mkfs program.
The list of options should be either comma-separated or surrounded by double quotes, depending on the file system. Check the mkfs man page for the file system you want to create for example mkfs. See the mount 8 man page for a full list of mount options, and fstab 5 for basics. Configures network information for the target system and activates network devices in the installation environment. The device specified in the first network command is activated automatically.
Activation of the device can be also explicitly required by the --activate option. There are several types of network device naming standards used to identify network devices with persistent names such as em1 or wl3sp0.
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. 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.
If prefix is omitted, 64 is used. You can also use auto for automatic configuration, or dhcp for DHCPv6-only configuration no router advertisements. To specify more than one name server, use this option once, and separate each IP address with a comma. The above command creates a bond device named mynetwork using the em1 and em2 interfaces as its slaves. Options in this list must be separated by commas " , " or semicolons " ; ".
If an option itself contains a comma, use a semicolon to separate the options. The interface name can be arbitrary for example, my-vlan , but in specific cases, the following conventions must be followed:. If the name contains a dot. For example: em1. Names starting with vlan must take the form of vlan ID - for example, vlan Slaves are separated by commas. Available values are stp , priority , forward-delay , hello-time , max-age , and ageing-time. This command uses the following format:.
You must use the nvdimm command to enable installation on these devices. Additionally, the specified device is implicitly marked as to be used, so a subsequent nvdimm use command for the same device is redundant. This action uses the following format:. Currently, only the value sector is available. The device must be already configured to the sector mode by the nvdimm reconfigure command.
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 screen 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 ". 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.
A network connection must be available to reach content definitions in a remote location. Used only if content-type is datastream. Use default to apply the default profile. All partitions created are formatted as part of the installation process unless --noformat and --onpart are used. For a detailed example of part in action, see Advanced Partitioning Example.
The value must be of one of the following forms:. To determine the size of the swap partition automatically but also allow extra space for your system to hibernate, use the --hibernation option:. It is not necessary on UEFI systems. See also the bootloader command. It is not necessary on BIOS systems. 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 Recommended Partitioning Scheme x 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. 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. If the partition cannot be allocated as primary usually due to too many primary partitions being already allocated , the partitioning process fails. A usage type defines a variety of tuning parameters to be used when making a filesystem.
For this option to work, the filesystem must support the concept of usage types and there must be a configuration file that lists valid types. This is similar to --fsprofile but works for all filesystems, not just the ones that support the profile concept. Valid values are xfs , ext2 , ext3 , ext4 , swap , vfat , efi and biosboot. 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 keys are stored as a separate file for each encrypted partition. Shut down and power 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.
During a Kickstart installation, if no completion method is specified, the halt option is used as default. The poweroff option is equivalent to the shutdown -p command.
The poweroff command is highly dependent on the system hardware in use. For other completion methods, see the halt , reboot , and shutdown Kickstart commands. The default CentOS 7 mdadm metadata version is not supported for the boot device. For a detailed example of raid in action, see Advanced Partitioning Example.
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. In certain situations, using a different chunk size than the default Kib can improve the performance of the RAID. Spare drives are used to rebuild the array in case of drive failure. If the given label is already in use by another filesystem, a new label will be created. It also creates three swap partitions, one on each drive.
For more information about this command, see the join section of the realm 8 man page. The exact format of the distinguished name depends on the client software and membership software. The root DSE portion of the distinguished name can usually be left out. This is not possible with all types of realm. Valid values include sssd and winbind. Not all realms support all values. By default, the client software is chosen automatically.
Possible values include active-directory or freeipa. Valid values include samba and adcli. By default, the membership software is chosen automatically. 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.
The reboot option is equivalent to the shutdown -r command. For other completion methods, see the halt , poweroff , and shutdown Kickstart options. The halt option is the default completion method if no other methods are explicitly specified in the Kickstart file.
Use of the reboot option might result in an endless installation loop, depending on the installation media and method. Due to the complexities involved with booting systems using kexec , it cannot be explicitly tested and guaranteed to function in every situation. 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.
Configures additional yum repositories that can be used as sources for package installation. You can add multiple repo lines. This option is required. If a repository has a name which conflicts with another previously added repository, it is ignored. Because the installation program uses a list of preset repositories, this means that you cannot add repositories with the same names as the preset ones. The variables that can be used in yum repo config files are not supported here.
This option cannot be used together with the --mirrorlist option in the same repository definition. The variables that can be used in yum repository configuration files are not supported here. This option cannot be used together with the --baseurl option in the same repository definition.
Without using this option, a repository configured in a Kickstart file will only be available during the installation process, not on the installed system. If multiple repositories provide the same packages, this number is used to prioritize which repository will be used before another.
Repositories with a lower cost take priority over repositories with higher cost. This is useful if multiple repositories provide the same package and you want to make sure it comes from a particular repository. This is useful if multiple repositories provide the same package and you want to make sure it comes from this repository.
This setting does not affect any other repositories, nor how the install. It tells the compose tools to not look at the package group information when mirroring trees so as to avoid mirroring large amounts of unnecessary data. Repositories used for installation must be stable.
The installation can fail if a repository is modified before the installation concludes. This gives you a chance to repair the system in case of any problems. By default, the installation program finds your system and mount it in read-write mode, telling you where it has performed this mount.
You can optionally select to not mount anything the --nomount option or mount in read-only mode the --romount option. Only one of these two options can be used. Automatically creates partitions required by your hardware platform. In contrast with autopart , this command only creates platform-specific partitions and leaves the rest of the drive empty, allowing you to create a custom layout.
This option is mutually exclusive with --plaintext. To create an encrypted password, you can use python :. This option is mutually exclusive with --iscrypted.
This means that the root user will not be able to log in from the console. This option will also disable the Root Password screens in both the graphical and text-based manual installation.
Sets the state of SELinux on the installed system. The default SELinux policy is enforcing. 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. To disable all four services, this entry should include no spaces:. Shut down the system after the installation has successfully completed. During a Kickstart installation, if no completion method is specified, the halt command is used.
The shutdown Kickstart option is equivalent to the shutdown command. For other completion methods, see the halt , poweroff , and reboot Kickstart options. If you install a display manager among your package selection options, this package creates an X configuration, and the installed system defaults to graphical.
The effect of the skipx option is overridden. Using the snapshot command, you can 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. This name must be unique within the volume group.
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 means that the user will not be able to log in from the console. By default, the ssh server is not started during the installation.
To make ssh available during the installation, boot the system with the kernel boot option inst. See Console, Environment and Display Options for details. If you want to disable root ssh access, while allowing another user ssh access, use the following:. Perform the Kickstart installation in text mode. Kickstart installations are performed in graphical mode by default. Starting with CentOS 7. In previous releases, the names were validated against pytz. Note that the graphical and text mode interfaces still use the more restricted pytz.
Tells the installation program to suppress the Unsupported Hardware Detected alert. If this command is not included and unsupported hardware is detected, the installation stalls at this alert.
This is a string of various system-specific fields separated by a comma. See the passwd 5 man page for more details. The groups must exist before the user account is created. See the group command.
This option will also disable the Create User screens in both the graphical and text-based manual installation. If not provided, the account will be locked by default. If not provided, the system default is used. If not provided, this defaults to the next available non-system UID.
If not provided, this defaults to the next available non-system group ID. 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.
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. 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. Recently I had the need to install CentOS 7 on an old machine to be used as a simple firewall.
There is an external repository, ELRepo , that packages external drivers and drivers Red Hat disables. RHEL and CentOS kernels and those from many other enterprise targeted distributions are API and ABI compatible for the entire lifespan of them, so building a driver for a kernel release can be reused for all kernel updates. ELRepo packages are built that way, in contrast with akmod method that need compiler tools in order to rebuild the driver module everytime the kernel is updated.
