cPanel & CloudLinux – Maximizing server density and stability

CloudLinux works by isolating each user into their own virtual environment and assigning resource blocks to each individual customer (CPU, IO, RAM, System processes).

This is accomplished by utilizing a transparent kernel-level technology called LVE (Lightweight Virtual Environment).

Segmenting control of resources gives the ability to further limit resource spikes by governing MySQL usage.

The built in MySQL Governor monitors usage, throttles abusers, and prevents MySQL overages before they can even happen.

Within WHM, CloudLinux gives you the visibility to see and control the exact resource usage of each website or end user.lvemgr

CloudLinux assigns each customer an LVE ID.

Limiting resources for each LVE is a snap using the LVE Manager via WHM.

Convert your cPanel server to a CloudLinux + cPanel in a few simple steps:

The CloudLinux installer detects which version of cPanel you have, your specific hardware requirements, and any type of virtualization being used.

Start by obtaining a license: Log in or register @

Find your existing key or request a free 30 day trial activation key and take note as you’ll need it for server installation in just a moment.

Download & run the conversion script

Login to your server via SSH as root

# wget

# sh cldeploy -k # if you have activation key


 # sh cldeploy -i # if you have IP based license


Once the server has rebooted, run SSH and check the proper kernel is being used with :

# uname –a

“lve” Will be listed in the kernel name. When you see this, you’ll know you’re setup properly.

Login to WHM and search “LVE”.

You should now see the LVEManager plugin that installed during the conversion.

cPanel + CloudLinux is a great choice whether you’re new to hosting or a datacenter looking to maximize the density of your current environment.
