如何查看linux版本

如何得知自己正在使用的linux是什么版本呢,下面的几种方法将给你带来答案!

1. 查看内核版本命令:

 1) [root@q1test01 ~]# cat /proc/version 

Linux version 2.6.9-22.ELsmp (bhcompile@crowe.devel.redhat.com) (gcc version 3.4.4 20050721 (Red Hat 3.4.4-2)) #1 SMP Mon Sep 19 18:00:54 EDT 2005

  2) [root@q1test01 ~]# uname -a 

Linux q1test01 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:00:54 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux

 3) [root@q1test01 ~]# uname -r 

2.6.9-22.ELsmp

2. 查看linux版本:

1) 登录到服务器执行 lsb_release -a ,即可列出所有版本信息,例如:

  [root@q1test01 ~]# lsb_release -a 

LSB Version: :core-3.0-amd64:core-3.0-ia32:core-3.0-noarch:graphics-3.0-amd64:graphics-3.0-

ia32:graphics-3.0-noarch

Distributor ID: RedHatEnterpriseAS

Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 2)

Release: 4

Codename: NahantUpdate2

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

2) 登录到linux执行cat /etc/issue,例如如下:

[root@q1test01 ~]# cat /etc/issue

Red Hat Enterprise Linux AS release 4 (Nahant Update 2)

Kernel \r on an \m

3) 登录到linux执行cat /etc/redhat-release ,例如如下:

[root@q1test01 ~]# cat /etc/redhat-release

Red Hat Enterprise Linux AS release 4 (Nahant Update 2)

注:这种方式下可以直接看到具体的版本号,比如 AS4 Update 1

4)登录到linux执行rpm -q redhat-release ,例如如下:

[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,比如上边的例子是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

另:第3)、4)两种方法只对Redhat Linux有效。
