centos 查看操作系统版本信息主要有以下几种方式:
1、通过 cat /proc/version 、uname
[[email protected] ~]# cat /proc/version

[[email protected] ~]# uname -r
2.6.32-279.el6.x86_64
[[email protected] ~]#
2、通过cat /etc/issue 、cat /etc/redhat-release

CentOS release 6.3 (Final)
Kernel \r on an \m
[[email protected] ~]# cat /etc/redhat-release

3、查看64位还是32位:
