Hi Everybody,

I am trying to install cPanel Unattended to CentOS 7.
Centos6 can also install without problems, but centos 6 support will be finished

My kickstart installation script is;

How to Unattended Installation cPanel on CentOS7 with Kickstart

Hello @Emirsah,

Here's a paraphrased quote from one of our Technical Analysts responding to a similar question:

The issue is that when your kickstart process is running the cPanel installer, it is actually still in the LiveOS for the CentOS installer, and isn't actually booted to the new server.

The way that Kickstart works around this is by running your postinstall stuff in a chroot.

However, the cpanel install script will use systemctl from within the chroot which will communicate with the running systemd PID 1, which is running outside of the chroot.

Systemd/systemctl refuses to start services under these circumstances.

This means that at the point where the installer needs to be able to start up MySQL, it can't. That is why the installation fails.

I believe the only solution would be to have your kickstart script do everything else it needs, then reboot to the new OS -- and you could then have the cPanel install script run post-reboot, where systemd won't be running in a chroot, and it won't complain.

I have seen some providers have their kickstart setup an @reboot cron job to run a shell script which waits until everything is up and running, runs the cPanel installer, and then removes it's own cron job.
Can you let me know if this information is helpful?

Thank you.
