查看系统版本

方法1:

[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: RedHatEnterpriseServer
Description:     Red Hat Enterprise Linux Server release 6.5 (Santiago)
Release:             6.5
Codename:       Santiago

说明: 这个命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版

LSB Version ----大白话就是 : 规范版本，以免乱套

Linux标准规范 (英语: Linux Standard Base,LSB)是一个在Linux基金会结构下对Linux发布版的联合项目,

使Linux操作系统符合软件系统架构,或文件系统架构标准的规范及标准。

方法2:

[root@localhost ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 6.5 (Santiago)
Kernel \r on an \m

方法3:

[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)

方法4:

[root@localhost ~]# rpm -qa | grep redhat-release
redhat-release-server-6Server-6.5.0.1.el6.x86_64

有的版本返回如下信息

[root@q1test01 ~]# rpm -q redhat-release

redhat-release-4AS-3

注: 这种方式下可看到一个所谓的release号，上边的例子是3

这个release号和实际的版本之间存在一定的对应关系，如下：

redhat-release-3AS-1 -> Redhat Enterprise Linux AS 3

redhat-release-3AS-7.4 -> Redhat Enterprise Linux AS 3 Update 4

redhat-release-4AS-2 -> Redhat Enterprise Linux AS 4

redhat-release-4AS-2.4 -> Redhat Enterprise Linux AS 4 Update 1

redhat-release-4AS-3 -> Redhat Enterprise Linux AS 4 Update 2

redhat-release-4AS-4.1 -> Redhat Enterprise Linux AS 4 Update 3

redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4

说明：第3)、4)两种方法只对Redhat Linux有效

版本说明

* Red Hat Enterprise Linux AS — for high-end and mission-critical systems (Advanced Server)

* Red Hat Enterprise Linux ES — for small/mid-range servers (Entry Server )

* Red Hat Enterprise Linux WS — for technical/design workstation clients (workstation)
