You can also add commands to execute on the system after the
installation is completed. If you have properly configured the network
in the kickstart file, the network is enabled. If you would like to
include a post-installation script, type it in the text area.
 | Caution |
|---|
| | Do not include the %post command. It will be added
for you.
|
For example, to change the message of the day for the newly
installed system, add the following command to the
%post section:
echo "Hackers will be punished!" > /etc/motd |
If you want your post-installation script to run outside of the chroot
environment, click the checkbutton next to this option on the top of
the Post-Installation page. This is equivalent to
the using the --nochroot option in the
%post section.
 | Tip |
|---|
| | If you want to make any changes to the newly installed filesystem in
the post-installation section outside of the chroot environment, you
need to append the directory name with
/mnt/sysimage.
|
For example, if you check the Run outside of the chroot
environment button, the previous example needs to be changed
to the following:
echo "Hackers will be punished!" > /mnt/sysimage/etc/motd |
If you want to specify a scripting language to use to execute your
script, click the Use an interpreter button and
enter the interpreter in the text box beside the button. For example,
/usr/bin/perl can be specified for a Perl
script. This option corresponds to using %post --interpreter
/usr/bin/perl in your kickstart
file.
The post-installation script can be used to perform any useful
functions such as the following examples.
Turn services on and off:
/sbin/chkconfig --level 345 telnet off
/sbin/chkconfig --level 345 finger off
/sbin/chkconfig --level 345 lpd off
/sbin/chkconfig --level 345 httpd on |
Run a script named runme from an NFS share:
mkdir /mnt/temp
mount 10.10.0.2:/usr/new-machines /mnt/temp
open -s -w -- /mnt/temp/runme
umount /mnt/temp |
Add a user to the system:
/usr/sbin/useradd bob
/usr/bin/chfn -f "Bob Smith" bob
/usr/sbin/usermod -p 'kjdf$04930FTH/ ' bob |
