10.2. Creating a Kickstart file by performing a manual installation

Procedure

1. Install RHEL. For more details, see Interactively installing RHEL from installation media.

   During the installation, create a user with administrator privileges.

2. Finish the installation and reboot into the installed system.
3. Log into the system with the administrator account.

4. Copy the file /root/anaconda-ks.cfg to a location of your choice. The file contains information about users and passwords.

   • To display the file contents in terminal:

     # cat /root/anaconda-ks.cfg

     You can copy the output and save to another file of your choice.

   • To copy the file to another location, use the file manager. Remember to change permissions on the copy, so that the file can be read by non-root users.

5. Install the pykickstart package.

   # dnf install pykickstart

6. Run ksvalidator on your Kickstart file.

   $ ksvalidator -v RHEL10 /path/to/kickstart.ks

   Replace /path/to/kickstart.ks with the path to the Kickstart file you want to verify.

   重要

   The validation tool cannot guarantee the installation will be successful. It ensures only that the syntax is correct and that the file does not include deprecated options. It does not attempt to validate the %pre, %post and %packages sections of the Kickstart file.
