[http://www.centos.org CentOS] is an Enterprise-class Linux Distribution derived from sources freely provided to the public by [http://www.redhat.com/ RedHat]. CentOS versions 5 and 6 are maintained by a group of volunteers who supply 100% compatible re-compilations from the latest [ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Client/en/os/SRPMS/ client] and [ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/ server] SRPMs for RHEL5, and [ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Client/en/os/SRPMS/ client] and [ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/ server] SRPMs for RHEL6 with all security fixes, bugfixes and feature enhancements.  The CentOS mailing list is also available from the public newsserver news.gmane.org (the name is gmane.linux.centos.general; posting is allowed).

Version 5 is based on kernel 2.6.18 and is still suitable for computing in X-ray crystallography. Maintenance updates to this version are planned to be made available until [http://www.zdnet.com/blog/open-source/red-hat-extends-red-hat-enterprise-linux-lifecycle-to-ten-years/10237 Mar 31st, 2017].

Version 6 is based on kernel 2.6.32 and is quite suitable for computing in X-ray crystallography. Maintenance updates to this version are planned to be made available until [http://www.zdnet.com/blog/open-source/red-hat-extends-red-hat-enterprise-linux-lifecycle-to-ten-years/10237 Nov 31st, 2020].

CentOS 7 is the current distribution (based on kernel 3.10), and advisable for the latest hardware.


32bit and 64bit versions exist for a number of platforms; most notably for Intel and compatible processors. On PC-type hardware, one should probably choose the 64bit version if the machine has more than 2GB of memory and is used for computing. The 32bit version is better for web surfing: for example, there are more 32bit Firefox plugins than 64bit ones (but of course one could manually install the 32bit Firefox on a 64bit machine).
