Upgrading your operating system is crucial for performance, security, and access to new features. In this article, we'll discuss how to forcefully upgrade CloudLinux from version 7 to 8.
Prerequisites
Before you proceed with the upgrade, ensure that you have:
- Backup: Always take a complete backup of your data and configurations.
- Sufficient Disk Space: Make sure your server has enough disk space for the upgrade.
- Root Access: You need to have root privileges to perform the upgrade.
Step-by-Step Upgrade Process
1. Prepare the Environment
Before initiating the upgrade, it’s essential to update your current system:
yum update -y
2. Install the Latest CloudLinux 7 Packages
To ensure a smooth transition, install the latest updates for CloudLinux 7:
yum clean all
yum upgrade -y
3. Install the CloudLinux 8 Packages
To prepare for the upgrade to CloudLinux 8, you need to install the CloudLinux 8 repository:
yum install https://repo.cloudlinux.com/cloudlinux/8/updates/x86_64/Packages/cloudlinux-release-8-1.el8.x86_64.rpm -y
4. Begin the Upgrade Process
Now you can begin the forceful upgrade from CloudLinux 7 to 8. This command will start the upgrade:
yum --releasever=8 --setopt=clean_requirements_on_remove=1 --setopt=install_weak_deps=False --assumeyes distro-sync
5. Handle Configuration Files
During the upgrade, if you have modified configuration files, you'll need to manually merge or handle those changes. Look for .rpmsave or .rpmnew files.
6. Reboot the System
Once the upgrade process is complete, it’s important to reboot the server to apply the changes:
reboot
7. Verify the Upgrade
After rebooting, verify that the system has upgraded successfully by checking the version:
cat /etc/redhat-release
Post-Upgrade Actions
After the upgrade, you should perform the following:
- Check Services: Ensure that all necessary services are running correctly.
- Update Security Settings: Review your security configurations in accordance with the new system.
- Install Additional Packages: If needed, install any additional packages or dependencies that are required for your applications.
Conclusion
Upgrading from CloudLinux 7 to 8 can significantly enhance your server's performance and security. Following the above steps will help you perform a forceful upgrade successfully. Always ensure that you have proper backups and a recovery plan in place before executing major system changes.
