CentOS (Community ENTerprise Operating System) is one of the Linux distributions. It is derived from the source code released by Red Hat Enterprise Linux in accordance with open source regulations. compiled. Because it comes from the same source code, some servers that require high stability use CentOS instead of the commercial version of Red Hat Enterprise Linux.
CentOS is an enterprise-level Linux distribution based on Red Hat Linux that can freely use source code. Each version of CentOS is supported (via security updates) for ten years. A new version of CentOS is released approximately every two years, and each version of CentOS is updated regularly (approximately every six months) to support new hardware. In this way, a secure, low-maintenance, stable, highly predictable, and highly repeatable Linux environment is established. [1] CentOS is the abbreviation of Community Enterprise Operating System.
CentOS is the product of recompilation of RHEL (Red Hat Enterprise Linux) source code, and many known bugs have been corrected on the basis of RHEL. Compared with other Linux distributions, its stability is trustworthy. In addition, since the Fedora Core plan is also rooted in the Red Hat system, in most cases, friends who use Fedora Core can also complete the construction and installation of servers through various CentOS-related techniques and methods introduced on this site. maintenance work. But compared to stability, Fedora Core focuses more on the latest technology and is more oriented to desktop applications and development testing, which also causes the stability of Fedora Core to be considered as a secondary aspect.
RHEL has always provided a source code distribution method. CentOS recompiles the source code released by RHEL to form a usable binary version. Since the source code of LINUX is GNU, it is legal to obtain the source code of RHEL and compile it into a new binary. It’s just that REDHAT is a trademark, so the REDHAT trademark must be removed in the new release.
REDHAT's attitude towards this kind of distribution is: "We are not actually opposed to this kind of distribution. The users who really pay us do not value the system itself, but the commercial services we provide. .”
So, CentOS can get all the functions of RHEL, even better software. However, CentOS does not provide commercial support to users, and of course it does not bear any commercial responsibility.
But if it is a purely business-oriented enterprise, it is recommended to purchase RHEL software and purchase corresponding services. This saves you IT management costs and provides you with professional services.
CentOS announced that it would join Red Hat in early 2014.

Alternatives to CentOS include AlmaLinux, RockyLinux, and OracleLinux. 1.AlmaLinux provides RHEL compatibility and community-driven development. 2. RockyLinux emphasizes enterprise-level support and long-term maintenance. 3. OracleLinux provides Oracle-specific optimization and support. These alternatives have similar stability and compatibility to CentOS, and are suitable for users with different needs.

CentOS is suitable for enterprise and server environments due to its stability and long life cycle. 1.CentOS provides up to 10 years of support, suitable for scenarios that require stable operation. 2.Ubuntu is suitable for environments that require quick updates and user-friendly. 3.Debian is suitable for developers who need pure and free software. 4.Fedora is suitable for users who like to try the latest technologies.

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.

CentOS alternatives include RockyLinux, AlmaLinux, and OracleLinux. 1. RockyLinux and AlmaLinux provide stable distributions compatible with RHEL, suitable for users who need long-term support. 2. CentOSStream is suitable for users who focus on new features and development cycles. 3. OracleLinux is suitable for users who need enterprise-level support.

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.

The end of CentOS has had a significant impact on users, with users having the option of RHEL, AlmaLinux, Debian or Ubuntu as alternatives. 1. The migration cost is high, requiring time and money. 2. Community division affects open source projects. 3.RHEL provides commercial support, but it is costly. 4.AlmaLinux is similar to CentOS and has low migration costs. 5. Debian and Ubuntu need more time to adapt.

CentOS is suitable as an enterprise-class server operating system because it is stable, secure and free. 1) It is based on RHEL and provides high compatibility with RHEL. 2) Use yum for package management to ensure that the software is easy to install and update. 3) The community regularly releases security patches, with a support cycle of up to 10 years.

The reason why CentOS stopped maintaining is RedHat's strategic change. User response strategies include: 1. Migrating to other distributions, such as UbuntuServer, Debian or RockyLinux; 2. Continue to use CentOS7 until June 2024; 3. Turning to CentOSStream; 4. Build solutions, such as custom distributions based on RHEL or using container technology.
