Alternatives to CentOS include UbuntuServer, Debian, Fedora, RockyLinux, and AlmaLinux. 1) UbuntuServer is suitable for basic operations, such as updating software packages and configuring the network. 2) Debian is suitable for advanced usage, such as using LXC to manage containers. 3) RockyLinux can optimize performance by adjusting kernel parameters.

Linux was first compiled by Linus Benedict Torvalds in 1991. Introduction to various Linux distributions and their similarities and differences. Prior to this, Richard Stallman created the Free Software Foundation (FSF) organization and the GNU project Linux distribution introduction, and continued to compile and create GNU programs (the license form of such programs is GPL: General Public License). As outstanding programmers and developers continue to join the GNU organization, the Linux we see today is created, or GNU/Linux. Linux distributions can be roughly divided into

CentOS is a stable, enterprise-grade Linux distribution suitable for server and enterprise environments. 1) It is based on RedHatEnterpriseLinux and provides a free, open source and compatible operating system. 2) CentOS uses the Yum package management system to simplify software installation and updates. 3) Support advanced automation management, such as using Ansible. 4) Common errors include package dependency and service startup issues, which can be solved through log files. 5) Performance optimization suggestions include the use of lightweight software, regular cleaning of the system and optimization of kernel parameters.

CentOS is an open source distribution based on RedHatEnterpriseLinux, focusing on stability and long-term support, suitable for a variety of server environments. 1. The design philosophy of CentOS is stable and suitable for web, database and application servers. 2. Use YUM as the package manager to release security updates regularly. 3. Simple installation, you can build a web server with a few commands. 4. Advanced features include enhanced security using SELinux. 5. Frequently asked questions such as network configuration and software dependencies can be debugged through nmcli and yumdeplist commands. 6. Performance optimization suggestions include tuning kernel parameters and using a lightweight web server.

CentOS was terminated because RedHat shifted its focus to CentOSStream, which was used to speed up the RHEL development cycle and drive users to move to RHEL. Alternatives include: 1.RockyLinux, 2.AlmaLinux, 3.OracleLinux. Compatibility, support, and long-term planning are considered when choosing an alternative.

CentOS needs alternatives because CentOSStream no longer provides long-term support. Alternative options include: 1. RockyLinux, which provides 10 years of life cycle support, suitable for users who need stability. 2.AlmaLinux also provides 10 years of support and has strong community support. 3. OracleLinux, provides RHEL-compatible version, and flexible life cycle management.

CentOS has stopped maintaining and has moved to CentOSStream and no longer provides a production-friendly version. Impacts include system migration and enterprise reevaluation of Linux policies. Alternatives are: 1. Migrate to RHEL, 2. Turn to Ubuntu or Debian, 3. Consider CentOSStream as a test platform, 4. Use AlmaLinux or RockyLinux. It is recommended to develop a migration plan as early as possible to evaluate existing system and team needs.

Alternatives to CentOS include AlmaLinux, RockyLinux, and OracleLinux. 1.AlmaLinux and RockyLinux rebuild RHEL 1:1, providing high stability and compatibility, suitable for enterprise environments. 2. OracleLinux provides high performance through UEK, suitable for users who are familiar with the Oracle technology stack. 3. When choosing, stability, community support and package management should be considered.
