System-config-packages iso
For systems that are disconnected from the Internet or Red Hat Network, using the yum update command with the Red Hat Enterprise Linux installation ISO image is an easy and quick way to upgrade systems to the latest minor version. The following steps illustrate the upgrading process:.
Create a target directory to mount your ISO image. This directory is not automatically created when mounting, so create it before proceeding to the next step, as root , type:. As root , type:. Here, the -o loop option is required to mount the file as a block device. An installation process that is time-consuming and complex affects the resiliency and scale of the network.
GISO is built using a build script gisobuild. Install update to identify and update dependant packages. The following are the known problems and limitations with the customized ISO:.
GISO image size more than 1. Ensure that GISO does not exceed that limit. The following image shows the workflow for building and installing golden ISO. Displays an error and exits build process if there are multiple base RPMs of same release but different versions. Performs compatibility check and dependency check for all the RPMs. This enhancement provides you with the flexibility to use the gisobuild.
You can also add a ztp. The ZTP configuration is applied on the router when the current software version is replaced or rolled back to a version with GISO image, and is used whenever ZTP is run to automatically provision the router. The tool supports more than one repository. YAML is a markup file that serves as a template to provide the package list and manage the build options. Set the clean option to true if you use the same build directory after the first GISO is created.
Ensure that you set the option to true for every successive GISO build. For example, if the : symbol is missing, or if an unsupported symbol is used in the template, the GISO build displays errors. The full-iso option is used to build a full ISO image xrv9k-full-x Verify that the Linux utilities mount , rm , cp , umount , zcat , chroot , mkisofs are present in the system. These utilities will be used by the script. Ensure privileges are available to execute all of these Linux commands.
However, if you are using Docker, these utilities are not required. Kernel version of the system must be later than 3. Verify that a libyaml rpm supported by the Linux kernel is available to successfully import yaml in the tool. User should have proper permission for security rpm k9sec-rpm in rpm repository, else security rpm would be ignored for Golden ISO creation. The system from where the gisobuild. Copy the script gisobuild. Ensure that this system meets the pre-requisites described above in the Before You Begin section.
Run the script gisobuild. The --iso option is mandatory, and either or both --repo or --pkglist options must be provided. For ASR series routers, upgrade to release 6. The -i option is mandatory, and either or both -r or -c options must be provided. Use show instal active command to see the list of RPMs. 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. 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.
If not provided, Anaconda uses the VNC default port of This is optional, but recommended. For a detailed partitioning example including volgroup , see Advanced Partitioning Example. If you use this option, do not specify a partition. The default value is 4 MiB , and the minimum value is 1 MiB. Applicable only to newly created volume groups. Create the partition first, then create the logical volume group, and then create the logical volume. Configures the X Window System.
If you install the X Window System with a Kickstart file that does not include the xconfig command, you must provide the X configuration manually during installation.
Do not use this command in a Kickstart file that does not install the X Window System. It is currently not possible to specify KDE as your default desktop environment using this option.
This is a known issue. The zerombr initializes any invalid partition tables that are found on disks and destroys all of the contents of disks with invalid partition tables. Define a Fibre channel device. This option only applies on IBM System z. All of the options described below must be specified. Takes the form of a digit number, preceded by 0x.
You can specify packages by environment , group , or by their package names. Several environments and groups that contain related packages are defined. Each entry has an ID, user visibility value, name, description, and package list.
If the group is selected for installation, the packages marked mandatory in the package list are always installed, the packages marked default are installed if they are not specifically excluded elsewhere, and the packages marked optional must be specifically included elsewhere even when the group is selected.
If you are not sure what packages should be installed, select the Minimal Install environment. Minimal install provides only the packages which are essential for running CentOS 7. This will substantially reduce the chance of the system being affected by a vulnerability.
If necessary, additional packages can be added later after the installation. To install a bit package on a bit system, append the package name with the bit architecture for which the package was built; for example, glibc. The --multilib option also must be specified in the Kickstart file; see the available options below. Initial Setup does not run after a system is installed from a Kickstart file unless a desktop environment and the X Window System were included in the installation and graphical login was enabled.
This means that by default, no users except for root are created. You can either create a user with the user option in the Kickstart file before installing additional systems from it see Kickstart Commands and Options for details or log into the installed system with a virtual console as root and add users with the useradd command. This command installs all packages which are part of the Infrastracture Server environment.
Only a single environment can be specified in the Kickstart file. This group contains all packages which are known to cause file conflicts, and is intended to be excluded. Specify individual packages by name, one entry to a line.
