Is centos linux or unix
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.
