Convert Cyber Panel to CloudLinux OS and install CageFS

by Thạch Phạm

What is CloudLinux?

CloudLinux OS is an operating system designed specifically for hosting service providers, developed in 2009 by CloudLinux Inc. CloudLinux uses the OpenVZ core platform and is fully compatible with CentOS/RHEL software packages. In terms of features and specifications, CloudLinux is designed to increase the stability and security of the server while optimizing the server’s processing capacity by dividing the resource limit. CPU, RAM, I/O resources to each hosting account. The two most important components of CloudLinux are the Lightweight Virtualized Environment (LVE) and CageFS.

Lightweight Virtualized Environment (LVE) is a core technology responsible for dividing and limiting server resources for each hosting account to prevent an account from using too many resources, leading to overloading the hosting server system.

CageFS is CloudLinux’s outstanding technology that is responsible for creating virtual system partitions to avoid the hosting accounts being able to see each other, thereby completely preventing hijacking as well as interfering with account data other in the same system.
