Introduction:
Converting from CentOS 8 to Rocky Linux can be a smooth and straightforward process if done correctly. In this step-by-step guide, we will walk you through the necessary steps to successfully transition from CentOS 8 to Rocky Linux. By following these instructions carefully, you can ensure a seamless migration to the new operating system without any disruptions to your workflow. Let’s get started!
Preparing Your System for Conversion
CentOS 8 users were left in a bit of a predicament when CentOS announced that it would be shifting its focus to CentOS Stream, effectively discontinuing CentOS 8 support. This left many users searching for an alternative that would provide long-term support and stability. One such alternative that has gained popularity is Rocky Linux, a community-driven enterprise operating system designed to be a drop-in replacement for CentOS.
If you are considering converting from CentOS 8 to Rocky Linux, there are a few steps you will need to take to prepare your system for the transition. In this article, we will walk you through the process of preparing your system for conversion to Rocky Linux.
The first step in preparing your system for conversion is to ensure that your CentOS 8 system is up to date. This includes installing any available updates and patches to ensure that your system is running the latest software versions. You can do this by running the following commands in your terminal:
sudo yum update
Once your system is up to date, the next step is to back up any important data on your system. While the conversion process should not result in any data loss, it is always a good idea to have a backup of your data in case something goes wrong during the conversion process. You can back up your data using a variety of methods, such as using an external hard drive or cloud storage service.
After backing up your data, the next step is to disable any third-party repositories that you may have enabled on your CentOS 8 system. This is important because these repositories may not be compatible with Rocky Linux and could cause issues during the conversion process. You can disable third-party repositories by editing the repository configuration files in the /etc/yum.repos.d/ directory and setting the enabled parameter to 0.
Once you have disabled any third-party repositories, the next step is to remove any packages that may conflict with Rocky Linux. This includes packages that are not included in the Rocky Linux repositories or packages that have been modified from their original versions. You can identify these packages by running the following command:
rpm -qa –qf “%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}n” | sort > centos_packages.txt
After identifying the conflicting packages, you can remove them using the following command:
sudo yum remove package_name
Finally, before proceeding with the conversion process, it is recommended to reboot your system to ensure that any changes you have made take effect. You can reboot your system by running the following command:
sudo reboot
In conclusion, preparing your system for conversion from CentOS 8 to Rocky Linux involves ensuring that your system is up to date, backing up your data, disabling third-party repositories, removing conflicting packages, and rebooting your system. By following these steps, you can help ensure a smooth and successful transition to Rocky Linux.
Migrating Packages and Repositories
When it comes to migrating from CentOS 8 to Rocky Linux, one of the key steps is transferring your packages and repositories. This process can be complex, but with the right guidance, it can be done smoothly and efficiently. In this article, we will provide a step-by-step guide on how to migrate your packages and repositories from CentOS 8 to Rocky Linux.
The first step in migrating your packages and repositories is to ensure that you have a backup of all your data. This is crucial in case anything goes wrong during the migration process. Once you have a backup in place, you can begin the migration process.
The next step is to update your CentOS 8 system to the latest version. This will ensure that you have all the necessary updates and patches before migrating to Rocky Linux. You can do this by running the following command:
sudo dnf update
Once your system is up to date, you can begin the migration process. The first thing you will need to do is remove the CentOS repositories from your system. You can do this by editing the repository files in the /etc/yum.repos.d/ directory and commenting out or removing the CentOS repositories.
Next, you will need to add the Rocky Linux repositories to your system. You can do this by creating a new repository file in the /etc/yum.repos.d/ directory and adding the following content:
[rocky]
name=Rocky Linux $releasever – Base
baseurl=http://mirror.rockylinux.org/$releasever/BaseOS/$basearch/os/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
Once you have added the Rocky Linux repositories, you can begin migrating your packages. You can do this by running the following command:
sudo dnf distro-sync
This command will upgrade all your packages to the versions available in the Rocky Linux repositories. It is important to note that some packages may not be available in the Rocky Linux repositories, so you may need to find alternative packages or compile them from source.
After migrating your packages, you will need to update your system to reflect the changes. You can do this by running the following command:
sudo dnf update
This will ensure that your system is fully up to date with the new packages from Rocky Linux. Once you have completed these steps, your migration from CentOS 8 to Rocky Linux should be complete.
In conclusion, migrating your packages and repositories from CentOS 8 to Rocky Linux can be a complex process, but with the right guidance, it can be done smoothly and efficiently. By following the steps outlined in this article, you can successfully migrate your packages and repositories to Rocky Linux and continue using your system with minimal disruption.
