First, you will need to get activation key or an IP-based license or you can use 30-days trial key.
You will need to have root level access in order to proceed further :
$ wget https://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy
$ sh cldeploy -k
# if you have activation key
OR
$ sh cldeploy -i # if you have IP based license
$ reboot
Once the installation is completed, the server needs to be rebooted.
