How to Backup & Migrate All CloudLinux Settings to Another Server

Issue

We are planning a server migration and want to ensure that all CloudLinux related settings remain the same.

Environment

• CloudLinux OS 6(h)/7(h)/8
• cPanel/Plesk/DirectAdmin/No panel

Solution

That the majority of native backup/restoration tools from control panels do include those files; for the most part, those are applicable for manual migration or for servers without a control panel.

LVE Limits and Packages   

To move LVE and packages' limits, just move the /etc/container/ve.cfg file to a new server, and then run # lvectl apply all

CageFS

If you haven't made any changes to the CageFS configuration files, there's no need to backup them. They will get re-created on a new server during the first installation.

If you did customize CageFS configs, move the /etc/cagefs/cagefs.mp file, and/or /etc/cagefs/conf.d directory to a new server and run

# cagefsctl --force-update && cagefsctl--remount-all

PHP Selector

To back up the PHP Selector settings, move the /etc/cl.selector directory to a new server and run:

cagefsctl --setup-cl-selector

To restore the user's settings from PHP Selector, please refer to this guide.

Basically, custom PHP settings migration plan is next:

• Restore user home dirs
• Remove all CageFS\Selector directories with

  rm -rf /var/cagefs/*/*/etc/cl.selector
  rm -rf /var/cagefs/*/*/etc/cl.php.d
  

• Regenerate them with

  cagefsctl --force-update-etc
