How to check if CloudLinux is installed?

To check if CloudLinux is installed on your server, here are a few quick and effective methods:

Check the OS release file

CloudLinux replaces the default CentOS/RHEL release file. Run:

cat /etc/redhat-release

If CloudLinux is installed, you’ll see something like:

CloudLinux release 9.2 (Luna Amarilla)

If it shows CentOS or AlmaLinux, then CloudLinux is not installed.

Check the Kernel Version

CloudLinux uses a custom kernel called lve (Lightweight Virtual Environment). Run:

uname -r

A CloudLinux system will typically show something like:

3.10.0-962.3.2.lve1.5.41.el7.x86_64

If the kernel contains lve, it’s a strong sign that CloudLinux is active.

Use cldetect Tool

If CloudLinux tools are installed, you can run:

cldetect --get-os

It will return:

cloudlinux

If the tool is not found, it’s possible CloudLinux is not installed or the environment is not fully converted.

Check for LVE Utilities

Try checking the presence of LVE-related commands:

which lveps

or

rpm -qa | grep lve

If these tools are installed, CloudLinux is most likely present.

Use hostnamectl

Another quick way is to check the OS name via:

hostnamectl

Look for the Operating System line. For example:

Operating System: CloudLinux 9.2 (Luna Amarilla)

Bonus – Check Yum Repos

CloudLinux uses its own repositories. Check your repo list:

ls /etc/yum.repos.d/

You’ll see entries like:

cloudlinux.repo
cloudlinux-rollout.repo

These are indicators of a CloudLinux environment.
