CloudLinux is a commercial Linux distribution aimed at shared hosting providers. It is based on the CentOS operating system and uses the OpenVZ kernel and rpm package manager. CloudLinux has many features that make it a suitable drop-in replacement for CentOS. The operating system uses rpm package management and CageFS storage for ease of use.
It uses CageFS
CloudLinux is a server operating system based on CageFS, a virtualized file system that prevents server hacking. This secure system keeps users’ files and configuration files hidden from other users. It also prevents symlink attacks, enabling you to choose which PHP version to use for your servers.
Using CloudLinux is easy. It comes with a CloudLinux installation wizard that enables you to install all the necessary components of the CloudLinux OS. You can also use the command line to set up CageFS. After setting up the necessary components, you can then start using the service.
CloudLinux has an integrated, virtualized per-user file system. This prevents users from seeing each other’s files and preventing privileged users from exploiting sensitive information. This also prevents information disclosure attacks and privilege escalation. In addition, CloudLinux allows you to monitor resource usage by account, allowing you to see how much RAM and CPU your servers are using.
Another important feature of CloudLinux is that it improves server stability and performance. This technology isolates client accounts from one another, ensuring that one account does not negatively impact the performance of other accounts. By using this technology, CloudLinux can accommodate two times as many accounts as traditional servers.
It uses PHP Selector
If you want to change the default PHP version on Cloudlinux, you can use PHP Selector. To use PHP Selector, first log into your cPanel account. Then go to the LVE Manager tab. There, you can change the default PHP version, enable or disable specific PHP versions, and modify upload_max_filesize.
Besides CloudLinux, PHP Selector is also supported by EasyApache 4. It is necessary to set the PHP Selector to native in order to use this functionality. If you don’t want to change it to native, you can also switch to the Native PHP version, which uses EasyApache modules.
CloudLinux uses the CloudLinux PHP Selector, which is different from the default ea-php56 or alt-php. It is recommended that you use CloudLinux if you have cPanel EA4 installed on your server. Alternatively, you can use alt-php and /usr/local/bin/lsphp.
CloudLinux PHP Selector is a management tool for PHP that allows administrators to configure different PHP versions on one server. It also enables administrators to deny access to specific PHP versions and disable certain modules. PHP Selector also allows administrators to change the default PHP version. It supports PHP 4.9 through 5.5.
PHP Selector has many advantages. Apart from letting you choose between different PHP versions, it also provides easy management. It helps you organize your content and customize your cPanel interface. The selector extensions are also useful for WHM. They make managing content on your website much easier.
You can also use MultiPHP Manager to set different PHP versions for different domains on the same cPanel account. Nevertheless, make sure that you use the ea-phpXX option.
It uses HardenedPHP
HardenedPHP is a security measure implemented on web servers that protects against vulnerabilities in outdated PHP versions. It also allows you to use multiple PHP versions on the same shared web server. This prevents exploits from affecting your website and prevents a variety of attacks. However, you should always keep your server updated as there is no security measure that is 100% secure.
This security measure is implemented by CloudLinux to protect against old PHP scripts. CloudLinux also uses HardenedPHP to secure unused PHP versions. It also offers a PHP Selector that allows end users to choose the version they want to use. You can choose from popular PHP versions, unused versions, or latest PHP releases.
CloudLinux also provides isolation with its LVE design. This feature enables users to set resource limits, and prevents overloading the server. This prevents information disclosure and privilege escalation attacks. It also prevents server downtime. The benefits of using CloudLinux as a hosting service are numerous.
CloudLinux also offers high reliability and security. It protects websites against malware and other insecure scripts. It also reduces support costs. It is also 100% compatible with cPanel. In addition, it also includes a kernel-level security solution called SecureLinks. This feature prevents symlink attacks, one of the biggest nightmares of server administrators. It provides the best security solution for this vulnerability. This feature is also compatible with cPanel and is completely transparent to end customers.
It uses MySQL Governor
Cloudlinux uses MySQL Governor for upgrading MySQL and MariaDB databases. You can download the latest version of the software from the CloudLinux repositories. The MySQL Governor is compatible with MySQL 5.1 and 5.6 and high performance MariaDB 5.x and higher. It can be installed on any control panel or plain-based server. We tested it on a cPanel server and it worked fine.
CloudLinux comes with the MySQL Governor feature that helps you monitor your server’s CPU and disk IO usage. This feature prevents MySQL queries from exceeding LVE limits, thereby increasing server performance. The MySQL Governor also helps ensure that the server is stable and prevents over-usage of MySQL.
MySQL Governor also monitors the resource usage statistics per MySQL thread. The software comes with several modes for optimizing the server’s performance. One mode of operation places all users in a predefined LVE, and it automatically restarts long-running queries. Another mode allows administrators to restrict users based on their specific requirements.
Another advantage of CloudLinux is that it manages the server’s resources efficiently. The hardened kernel helps prevent spikes in resource usage from affecting your website. It also keeps the server’s CPU and disk usage within reasonable limits. Besides, it protects your website from over-usage from DDoS attacks, spambots, and brute-force attacks.
In addition, CloudLinux is compatible with multiple PHP versions. This ensures best performance and stability. The software also offers support for major control panels.
