CentOS6.5 installation, centos6.5 installation tutorial
1 CentOS 6.5 introduction CentOS (Community Enterprise Operating System) is one of the Linux releases, it is from the source code compiled by Red Hat Enterprise Linux according to open source code regulations. Because of the same source code, some servers that require high stability use CentOS instead of the commercial version of Red Hat Enterprise Linux. The difference between the two lies in that CentOS does not contain closed source code software.
