As CentOS 7 nears its end-of-life (EOL) in June 2024, system administrators and web hosting companies are actively seeking stable and secure alternatives. One popular option is CloudLinux, a commercial Linux distribution built specifically for shared hosting providers. Designed to improve server stability, security, and efficiency, CloudLinux is based on CentOS and offers a seamless transition path. If you're planning to move from CentOS 7 to CloudLinux, this guide outlines everything you need to know, from the benefits of CloudLinux to step-by-step migration tips and best practices.
Why Consider Moving from CentOS 7 to CloudLinux?
CentOS 7 has long been a reliable choice for enterprises and hosting providers due to its binary compatibility with RHEL centos 7 to cloud linux support has prompted many users to switch. Migrating from CentOS 7 to CloudLinux offers several advantages:
1. Extended Support
CloudLinux offers Extended Lifecycle Support (ELS) even for CentOS 7, allowing users to receive critical patches and updates beyond the EOL date. This provides more time for businesses to plan their infrastructure upgrades without risking security.
2. Enhanced Server Stability
With CloudLinux’s Lightweight Virtualized Environment (LVE) technology, hosting providers can allocate CPU, memory, and I/O resources per user or tenant. This prevents a single user from consuming all resources and ensures better uptime and performance for everyone.
3. Increased Security
CloudLinux integrates features such as CageFS (a virtualized per-user file system), hardened PHP versions, and kernel-level protections. These enhancements significantly reduce the attack surface of your server, especially in shared environments.
4. Optimized Performance
The OS includes tools like MySQL Governor and PHP Selector, allowing fine-tuned optimization of web applications. These are especially beneficial for hosting providers managing multiple tenants with different needs.
5. Compatibility
Since CloudLinux is based on RHEL/CentOS, transitioning from CentOS 7 to CloudLinux is smooth. Your existing configurations, software packages, and management tools (such as cPanel, WHM, or Plesk) are fully supported.
Pre-Migration Checklist
Before initiating the migration, it’s important to prepare your environment. Here are essential steps:
Backup Everything: Perform full system and data backups. Use tools like rsync, tar, or snapshot services.
Check Hardware Compatibility: Ensure your server hardware supports CloudLinux (virtually all servers compatible with CentOS will work).
Verify Software Versions: Confirm that your applications and control panels are compatible with CloudLinux.
Clean Up the System: Remove unused packages and ensure your system is stable before migration.
How to Migrate from CentOS 7 to CloudLinux
Moving from CentOS 7 to CloudLinux is straightforward, especially if you're using a supported control panel like cPanel or Plesk. Here’s a step-by-step process:
Step 1: Purchase a CloudLinux License
You can buy a license directly from CloudLinux or through a hosting partner. The license is associated with your server’s IP address.
Step 2: Install the CloudLinux Conversion Script
Log in as root and run the following commands:
Step 3: Reboot the Server
Once the script finishes, reboot your server:
Step 4: Register Your License
Register the CloudLinux license using the following command:
Step 5: Enable LVE and Other CloudLinux Features
After registration, install additional CloudLinux packages and features:
Post-Migration Recommendations
After migrating from CentOS 7 to CloudLinux, follow these best practices:
Update the System Regularly: Use yum update to apply security patches and feature updates.
Monitor Resource Usage: Leverage CloudLinux’s LVE Manager to monitor resource usage per user and prevent overload.
Test Websites and Applications: Ensure that hosted applications work correctly after the migration.
Enable CageFS for All Users: This isolates each account for enhanced security.
Common Issues and Troubleshooting
Kernel Not Updating: If the server still boots into a CentOS kernel, ensure the default boot entry points to the CloudLinux kernel using grub2-set-default.
License Errors: Use cldetect --check-license to verify if your license is valid and active.
cPanel Integration Issues: Run /usr/bin/cl-selector --rebuild-all if you face integration issues with alt-PHP and cPanel.
CloudLinux Alternatives to Consider
While CloudLinux is a robust solution, you may also explore:
AlmaLinux – A 1:1 binary-compatible fork of RHEL.
Rocky Linux – Another community-driven RHEL alternative.
Ubuntu Server – Especially for container-based or cloud-native environments.
However, for those running shared hosting environments, migrating from CentOS 7 to CloudLinux is often the best move due to its tailored tools and focus on multi-tenant performance and security.
Conclusion
The transition from CentOS 7 to CloudLinux not only extends your system’s lifespan but also equips it with enterprise-grade tools designed for stability, performance, and security centos 7 to cloud linux provides a business running multiple workloads on a shared environment, CloudLinux ensures you can manage resources effectively while keeping customers happy. With its smooth conversion process and long-term support options, CloudLinux is a strategic upgrade in the post-CentOS era.
If you're planning your migration, now is the time to act—before CentOS 7 officially reaches EOL.
