Linux下查看系统版本号信息的方法

查看Linux内核版本命令

1、cat /proc/version

[root@localhost ~]# cat /proc/version 
Linux version 2.6.32-696.23.1.el6.x86_64 (mockbuild@x86-01.bsys.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC) ) #1 SMP Tue Mar 13 22:44:18 UTC 2018

2、uname -a

[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-696.23.1.el6.x86_64 #1 SMP Tue Mar 13 22:44:18 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

查看Linux系统版本的命令

1、lsb_release -a，即可列出所有版本信息：

[root@localhost ~]# lsb_release -a
LSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID:    CentOS

这个命令适用于所有的Linux发行版，包括Redhat、SuSE、Debian…等发行版。

2、cat /etc/redhat-release，这种方法只适合Redhat系的Linux：

[root@localhost ~]# cat /etc/redhat-release
CentOS release 6.9 (Final)

3、cat /etc/issue，此命令也适用于所有的Linux发行版。
