Yes You can uninstall cloudlinux and revert back to centos and remove all cloudlinux files, In this case, we will ‘convert’ the system back to CentOS. Even if the original system was RHEL — we will still convert to ‘CentOS’ state.`
To uninstall CloudLinux, do:
$ wget -O cldeploy http://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy
$ sh cldeploy -c
Update your CentOS-provided RPMs
yum upgrade -y
Reboot the server to use the new non-CloudLinux kernel
reboot
Thank You~
