CentOS 5.11 32bit
CentOS image was officially applied and tested by Alibaba Cloud. It conforms fully with the upstream vendor's redistribution policy and aims to be 100% functionally compatible with RHEL (CentOS mainly changes packages to remove upstream vendor branding and artwork). CentOS Linux is no-cost and free to redistribute.
CentOS 5.11 is the eleventh update to the CentOS 5 distribution series. It contains a lot of bugfixes, updates and new functionality. Packages that have been upgraded in 5.11 since the 5.10 release include anacron, basesystem, bluez-utils, buildsys-macros, busybox, cluster_administration, clustermon, compiz, comps-extras, conga, etc.
