The Future of CentOS: What's Next?

CentOS will continue to develop through CentOS Stream in the future. CentOS Stream is no longer a direct clone of RHEL, but is part of RHEL development. Users can experience the new RHEL functions in advance and participate in development.

introduction

CentOS has been a mainstay of enterprise-class Linux distributions over the past few years, and it has won the favor of a large number of users for its stability and reliability. With Red Hat announcing the suspension of support for CentOS 8 and launching CentOS Stream, many people are concerned about how CentOS will develop in the future. The purpose of this article is to explore the future direction of CentOS and help you understand the possible impact of these changes on you and your team. By reading this article, you will learn about the location, alternatives, and how to continue using CentOS in the future.

Review of basic knowledge

CentOS, full name is Community Enterprise Operating System, is an open source distribution based on Red Hat Enterprise Linux (RHEL). It attracts a large number of corporate users with its free, stable and long-term support. However, in December 2020, Red Hat announced that it would stop supporting CentOS 8 and instead launch CentOS Stream, which undoubtedly brought considerable shock to many users who rely on CentOS.

As a rolling release, CentOS Stream aims to become an intermediate link in the RHEL development process and provide a preview of future versions of RHEL. This means that CentOS Stream will no longer be a direct clone of RHEL, but is part of RHEL development.

Core concept or function analysis

Definition and function of CentOS Stream

The emergence of CentOS Stream marks that CentOS is no longer a direct substitute for RHEL, but an intermediate link in RHEL development. Its function is to provide a platform that allows developers and users to experience the new functions and repairs of RHEL in advance, and also participate in the development process of RHEL.

// Example of CentOS Stream sudo yum install epel-release
sudo yum install centos-release-stream
sudo yum distro-sync

This example shows how to upgrade an existing CentOS system to a CentOS Stream. With these commands, you can convert your system into a rolling release version, thus achieving the latest RHEL development progress.

How does CentOS Stream work

The working principle of CentOS Stream is based on the RHEL development cycle. RHEL developers will release new code and fixes in CentOS Stream, which will be integrated into RHEL after being tested and verified. This means that CentOS Stream users can experience the new features of RHEL in advance, but also have to take more risks, as these features may be unstable.

From technical details, CentOS Stream's package management system still uses Yum, but due to its rolling release characteristics, users need to update the system frequently to keep it up to date. This can cause inconvenience to some business users, as they usually prefer a stable environment.

Example of usage

Basic usage

For those who are already using CentOS, migrating to CentOS Stream is a relatively simple process. Here is a basic migration example:

// Migrate to CentOS Stream
sudo yum install centos-release-stream
sudo yum distro-sync
sudo reboot

This code shows how to upgrade an existing CentOS system to a CentOS Stream. The functions of each line of command are to install the repository of CentOS Stream, synchronize the system packages and restart the system.

Advanced Usage

For users who want to develop on CentOS Stream, they can use their scrolling release features to test and develop new features. Here is an example of an advanced usage:

// Test new features on CentOS Stream sudo yum install git
git clone https://github.com/your-project/your-repo.git
cd your-repo
./configure
Make
sudo make install

This example shows how to clone a Git repository, compile and install a project on CentOS Stream. In this way, you can use the latest features of CentOS Stream for development and testing.

Common Errors and Debugging Tips

When using CentOS Stream, you may encounter common problems such as package dependency conflicts or system instability. Here are some common errors and their solutions:

• Package dependency conflict : Most dependency problems can be solved through the yum distro-sync command.
• System instability : Because CentOS Stream is released scrollly, the system may become unstable due to frequent updates. You might consider using the yum history command to roll back to a stable version.

Performance optimization and best practices

Performance optimization and best practices are very important when using CentOS Stream. Here are some suggestions:

• Periodic Updates : Since CentOS Stream is released scrolling, regularly updating the system ensures you get the latest features and fixes.
• Backup system : Due to the instability of the system, it is very important to back up the system regularly. You can use rsync or other backup tools to do this.
• Monitoring system : Use monitoring tools such as Nagios or Zabbix to monitor the performance and stability of the system, so that problems can be discovered and solved in a timely manner.

Pros and cons analysis and pitfalls

The advantage of CentOS Stream is that it allows users to experience the new features of RHEL in advance, and can also participate in the development process of RHEL. However, its disadvantage is that its rolling release characteristics may lead to system instability. This can be a big challenge for enterprise users, as they usually prefer a stable environment.

In actual use, you may encounter some pitfalls, such as package dependency conflicts, system instability, etc. These problems can be alleviated by regular updates, backup systems and monitoring systems, but users still need to have certain technical capabilities and risk awareness.

Overall, the emergence of CentOS Stream marks an important turning point in CentOS's future. Although it is no longer a direct alternative to RHEL, it still provides users with an opportunity to participate in RHEL development. For those who want to continue using CentOS, it is very important to understand the features and usage of CentOS Stream.
