如何查看linux版本

   1. 查看內核版本命令:

  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) 登錄到服務器執行 lsb_release -a ,即可列出所有版本信息,例如:

  [[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

  注:這個命令適用於所有的linux,包括Redhat、SuSE、Debian等發行版。

  2) 登錄到linux執行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) 登錄到linux執行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:這種方式下可以直接看到具體的版本號,比如 AS4 Update 1

  4) 登錄到linux執行rpm -q redhat-release ,例如如下:

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

  redhat-release-4AS-3

  注:這種方式下可看到一個所謂的release號,比如上邊的例子是3

  這個release號和實際的版本之間存在一定的對應關系,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)兩種方法只對Redhat Linux有效.
