How does CloudLinux improve server performance?

CloudLinux defines specific CPU, RAM, and IO limits for each user with LVE technology, preventing a single site from consuming all server resources and ensuring 100% uptime.

What is CageFS and why is it important?

CageFS is a technology that confines each user to their own virtual file system. Users cannot see each other's files, and security vulnerabilities do not spread to other accounts.

Can I convert my existing CentOS server to CloudLinux?

Yes, with the cDeploy script you can convert your existing CentOS or AlmaLinux server to CloudLinux OS with a single command without data loss.

Why Should You Choose CloudLinux?

Industry standard operating system that prevents a single site from consuming all resources on shared hosting servers, increases security, and customizes PHP versions.

LVE Manager

Set CPU, IO, Memory and Process count limits for each user with Lightweight Virtual Environment (LVE) technology. Instantly isolate sites that disturb their neighbors.

CageFS Technology

By virtualizing the file system, it traps each user in their own "cage". Users cannot see server configuration files or other users' data.

MySQL Governor

Monitors MySQL queries in real time. It detects users consuming excessive database resources and prevents database crash by instantly limiting them.

PHP Selector

Give your users freedom of choice, from PHP 5.x to the latest PHP 8.x versions. Each user can choose his own PHP version and modules.

HardenedPHP

Provides security patches for old and unsupported PHP versions (PHP 5.2, 5.3 , etc.). Your customers can continue to run their old scripts safely.

2026 SEO Performance

Server response time is critical for Core Web Vitals metrics. By optimizing resources, CloudLinux reduces TTFB time and helps sites rank in Google.

In-Depth Technical Analysis: CageFS and LVE

At the heart of CloudLinux LVE (Lightweight Virtual Environment) The technology works at the kernel level. This layer, added to the standard Linux kernel, monitors Apache, Nginx or LiteSpeed processes.

IO Limits: Eliminates the "Noisy Neighbor" effect by restricting disk read/write speed.
EP (Entry Processes): Limits simultaneous input operations (such as PHP scripts). This prevents Apache from hitting the MaxClients limit.
Symbolic Link Protection: It prevents symlink attacks at the kernel level with SecureLinks technology.

Frequently Asked Questions

Frequently asked questions about CloudLinux.

Does installing CloudLinux cause data loss?

No, CloudLinux installation is a conversion process. It replaces the kernel of your existing CentOS or AlmaLinux operating system. The disk is not formatted and your data is not deleted. However, we recommend that you make a backup before proceeding, just in case.

Which control panels is it compatible with?

CloudLinux; It is fully integrated with popular hosting control panels such as cPanel/WHM, Plesk, DirectAdmin and CyberPanel. The LVE Manager interface is embedded within these panels.

What happens if I don't use CloudLinux?

On a standard Linux server, if a single user consumes excessive CPU or RAM (due to an attack or bad coding), the entire server slows down or shuts down. CloudLinux prevents this. If you sell shared hosting, CloudLinux is a must.

Is the license instantly active?

Yes, the licenses you purchase through Eka Sunucu are instantly activated by our automation system upon payment confirmation and assigned to your IP address.
