本文汇总了多种查询CentOS版本信息的方法，包括使用cat命令查看/etc/issue和/etc/redhat-release文件，通过cat/proc/version获取Linux及GCC版本详情，利用uname命令的不同参数查看系统内核版本等。

查看CentOS版本信息的命令汇总：

1.cat /etc/issue 查看CentOS版本

[root@localhost ~]# cat /etc/issue
CentOS 7.3.1611 (Core)

2. cat /etc/redhat-release 查看CentOS版本

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

3. cat /proc/version查看Linux及Gcc版本

[root@localhost ~]# cat /proc/version
Linux version 3.10.0-514.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Tue Nov 22 16:42:41 UTC 2016

4.uname -a 查看Linux版本

[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

5.uname -r 查看Linux版本

[root@localhost ~]# uname -r
3.10.0-514.el7.x86_64

6.查看系统是32位或者64位的方法

[root@localhost ~]# getconf LONG_BIT
64

[root@localhost ~]# file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=3d705971a4c4544545cb78fd890d27bf792af6d4, stripped

7.查看gcc版本

[root@localhost ~]# gcc -v
Using built-in specs.
