CloudLinux is a proven solution for web hosting servers that drastically improves server stability and security, increases density, decreases support costs, and prevents churn. CloudLinux delivers these benefits by introducing the latest technologies specifically crafted for web hosting into its kernel. Combine these features with all its tools and integrate them with major control panels and it becomes a must-have for any web hosting server.
- LVE Limits
- MySQL Governor
- PHP Selector
- Simple CentOS/RHEL Conversion
CloudLinux is a Linux operating system optimized for web hosting. It is commercially supported and improves density, stability, and security in multi-tenant environments such as shared hosting servers. It is easy to deploy because it is interchangeable with the most popular RPM-based Linux distributions on the market, Red Hat EL and CentOS.
Converting your existing RHEL or CentOS server to CloudLinux is as simple as running a few commands and rebooting onto the CloudLinux kernel!

LVE Resource Limits
CloudLinux puts each user account on a shared server into a lightweight virtual environment (LVE). This allows the host to maintain control over resources such as CPU, IO, memory, the number of processes, and concurrent connections that any single account can use. The goal of LVE is to make sure that no single user can bring down the entire server.
MySQL often becomes a major headache for shared hosting companies. Keeping it stable might become difficult, and user queries can easily slow down the entire server. This is where MySQL Governor comes in. It’s ability to pinpoint abusers and throttle them in real time is unprecedented in the industry. Although some solutions for monitoring MySQL database usage already exist, they only display data from completed queries. MySQL Governor tracks CPU and disk IO usage for every user in real time. By using the dbtop utility, it is possible to see usage as it happens on a per user basis, ensuring that system admins always know what is going on.
Anyone who uses MySQL or MariaDB can start using MySQL Governor immediately. With MySQL, Governor administrators can monitor user’s activity and automatically throttle usage for users who exceed predefined limits. MySQL Governor provides shared hosting server administrators with an easy way to configure acceptable usage limits for CPU, disk IO read, and disk IO write. These are the three main resources that most commonly are affected by MySQL abusers. An increase in resources usage can cripple a server and make it extremely slow or even unresponsive. By focusing on these key resources, the MySQL Governor is highly effective.
MySQL Governor has also leveraged burstable limits to offer incremental, time-based settings. For example, an administrator can allow increased resource usage for the first ten seconds and then gradually limit usage over the following minutes. As a result, resources are throttled to maintain performance for other users. It is also possible to take more agressive action if increased resource usage persists for long periods.
The PHP Selector is a part of CloudLinux that allows users to select a specific version of PHP that they would like to run. It allows ultimate flexibility by offering all popular versions of PHP and more than 120 PHP extensions to choose from.
Each customer has different needs and with PHP being the dominant language on the Internet, CloudLinux provides versions 4.4, 5.1, 5.2, 5.3, 5.4, 5.5 and 5.6 for he user to choose from. The convenient UI lets a user easily switch between versions, select the extensions they require, and adjust PHP settings. No longer will you have to battle with the decision process of which PHP version you should run. No longer will you have to turn customers away or deploy additional servers with a specific version because thats what the customer requires. You can now set the native (default) version to the latest version and give your users the option to run older version if thats what they require.
CageFS extends LVE isolation to each user’s filesystem. Through virtualization, each user is effectively isolated into their own environment, preventing one user from seeing any other user on the server. This creates a new level of security, making it much more difficult for attackers to deface or steal data from a shared hosting server. Additionally, it guarantees no SUID scripts are available to the end user, preventing the majority of privilege escalation attacks. CageFS provides all of this while providing a fully functional environment!
