Copy /root/anaconda-ks.cfg on desktopX to a file called kickstart.cfg that student can edit.

[student@desktopX ~]$ sudo cat /root/anaconda-ks.cfg > kickstart.cfg

Make the following changes to kickstart.cfg.

1. Change the url command to specify the HTTP installation source media used in the classroom:

   url --url="http://classroom.example.com/content/rhel7.0/x86_64/dvd/"

2. Configure the network to use DHCP. There should only be a single network directive that looks like the following:

   network --bootproto=dhcp

3. Modify the disk configuration to only have the following three directives:

   # Clear the Master Boot Record
   zerombr
   # Partition clearing information
   clearpart --all --initlabel
   # Disk partitioning information
   part / --fstype="xfs" --ondisk=vda --size=5120
   

   Be sure the size is adjusted to 5120.

4. Comment the reboot directive:

   #reboot

5. Change the packages that are installed to include httpd, but not cloud-init. Simplify the package specification to look exactly like the following:

   @core
   chrony
   dracut-config-generic
   dracut-norescue
   firewalld
   grub2
   kernel
   rsync
   tar
   httpd
   -plymouth
   

6. Delete all of the content in the %post section except for the following lines:

   %post --erroronfail
   # make sure firstboot doesn't start
   echo "RUN_FIRSTBOOT=NO" > /etc/sysconfig/firstboot
   # append /etc/issue with a custom message
   echo "Kickstarted for class on $(date)" >> /etc/issue
   %end
   

7. Set the root password to redhat. Change the line that starts with rootpw to:

   rootpw --plaintext redhat

Use the ksvalidator command to check the Kickstart file for syntax errors.

[student@desktopX ~]$ ksvalidator kickstart.cfg

Copy kickstart.cfg to the /var/www/html/ks-config directory.

[student@desktopX ~]$ sudo cp ~student/kickstart.cfg /var/www/html/ks-config
