On workstation, run the lab installing-kickstart start command. This command runs a start script to determine whether the servera machine is reachable on the network. It also verifies that Apache is installed and configured on servera.

[student@workstation ~]$ lab installing-kickstart start

Use the ssh command to log in to servera as the student user. The systems are configured to use SSH keys for authentication, so a password is not required.
```
[student@workstation ~]$ ssh student@servera
...output omitted...
[student@servera ~]$  
```
Copy /root/anaconda-ks.cfg on servera to a file called /home/student/kickstart.cfg so that student can edit. Use the sudo cat /root/anaconda-ks.cfg > ~/kickstart.cfg command to copy the contents of /root/anaconda-ks.cfg to /home/student/kickstart.cfg. If sudo prompts for the password of the student user, use student as the password.
```
[student@servera ~]$ sudo cat /root/anaconda-ks.cfg > ~/kickstart.cfg
[sudo] password for student: student
```
Make the following changes to /home/student/kickstart.cfg.
1. Comment out the reboot directive:
```
#reboot
```
2. Comment out the repo command for the BaseOS repository. Modify the repo command for AppStream to point to the classroom's AppStream repository:
```
#repo --name="koji-override-0" --baseurl=http://download-node-02.eng.bos.redhat.com/rhel-8/devel/candidate-trees/RHEL-8/RHEL-8.2.0-updates-20200423.0/compose/BaseOS/x86_64/os
repo --name="appstream" --baseurl=http://classroom.example.com/content/rhel8.2/x86_64/dvd/AppStream/
```
3. Change the url command to specify the classroom's HTTP installation source media:
```
url --url="http://classroom.example.com/content/rhel8.2/x86_64/dvd/"
```
4. Comment out the network command:
```
#network  --bootproto=dhcp --device=link --activate
```
5. Set the root password to redhat. Change the line that starts with rootpw to:
```
rootpw --plaintext redhat
```
6. Delete the line that uses the auth command and add the authselect select sssd line to set the sssd service as the identity and authentication source.
```
authselect select sssd
```
  In Red Hat Enterprise Linux 8, the authselect command replaces the authconfig command.
7. Simplify the services command to look exactly like the following:
```
services --disabled="kdump,rhsmcertd" --enabled="sshd,rngd,chronyd"
```
8. Comment out the part commands. Add the autopart command:
```
# Disk partitioning information
#part biosboot --fstype="biosboot" --size=1
#part /boot/efi --fstype="efi" --size=100 --fsoptions="..."
#part / --fstype="xfs
autopart
```
9. Delete all content between the %post section and its %end. Add the following line: echo "Kickstarted on $(date)" >> /etc/issue
  The entire %post section should look like this.
```
%post --erroronfail
echo "Kickstarted on $(date)" >> /etc/issue
%end
```
10. Simplify the package specification to look exactly like the following:
```
%packages
@core
chrony
dracut-config-generic
dracut-norescue
firewalld
grub2
kernel
rsync
tar
httpd
-plymouth
%end
```
  When you are finished editing the file save and exit.
Use the ksvalidator command to check the Kickstart file for syntax errors.
```
[student@servera ~]$ ksvalidator kickstart.cfg
```

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

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

Exit from servera.

[student@servera ~]$ exit 
logout
Connection to servera closed.
[student@workstation ~]$

Finish

On workstation, run the lab installing-kickstart finish script to finish this exercise.

[student@workstation ~]$ lab installing-kickstart finish

This concludes the guided exercise.
