  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 ([email protected])
  (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:
  (注:这个命令适用于所有的linux,包括Redhat、SuSE、Debian等发行版。)
  [[email protected] ~]# [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 


  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 on an m

  3) 登录到linux执行cat /etc/redhat-release ,例如如下: 
  (注:这种方式下可以直接看到具体的版本号,比如 AS4 Update 1  )
  [root@q1test01 ~]# cat /etc/redhat-release 
  Red Hat Enterprise Linux AS release 4 (Nahant Update 2) 

  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。

  附:我在RedHat Linux下执行的结果:

  1. 查看内核版本命令:

  1)cat /proc/version
  [tao@localhost tao]$ cat /proc/version
  Linux version 2.4.20-8 *[email protected]) (gcc version 3.2.2 20030222 (Read Hat Linux 3.2.2-5)) #1 Thu Mar 13 17:54:28 EST 2003

  2)uname -a
  [tao@localhost tao]$ uname -a
  Linux Localhost.Localdomain 2.4.20-8 #1 Thu Mr 13 17:54:28 EST 2003 i686 i686 i386 GNU/Linux

  3)uname -r
  2.4.20-8

  2. 查看linux版本:

  1)lsb_relese -a --命令未找到
  [tao@localhost tao]$ lsb_relese -a
  -bash:lsb_release: command not dound

  2)cat /etc/issue --成功
  [tao@localhost tao]$ cat /etc/issue
  Red Hat Linux release 9 (Shrike)
  Kernel on an m

  3)cat /etc/redhat-release --成功
  [tao@localhost tao]$ cat /etc/redhat-release
  Red Hat Linux release 9 (Shrike)

  4)rpm -q redhat-release --成功
  [tao@localhost tao]$ rpm -q redhat-release
  redhat-release-9-3
