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

3)

[root@q1test01 ~]# uname -r

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@3.5.5Biz-46 ~]#

[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

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

3)

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

[root@q1test01 ~]# cat

/etc/redhat-release

Red Hat

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
