怎样查看Linux系统的版本

广达分享

  Linux系统,由代码组成的系统,自然也要用代码去查询。下面学习啦小编给大家分享查看linux系统版本的命令,欢迎阅读:

  Linux系统版本的命令——

  一、查看内核版本命令:

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

  Linux version 2.6.18-238.el5 (mockbuild@x86-012.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Sun Dec 19 14:22:44 EST 2010

  [root@SOR_SYS ~]#

  2)[root@SOR_SYS ~]# uname -r

  2.6.18-238.el5

  3)[root@SOR_SYS ~]# uname -a

  Linux SOR_SYS.99bill.com 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST 2010 x86_64 x86_64 x86_64 GNU/Linux

  [root@SOR_SYS ~]#

  二、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@SOR_SYS ~]# lsb_release -a

  LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch

  Distributor ID: RedHatEnterpriseAS

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

  Release: 4

  Codename: NahantUpdate4

  [root@SOR_SYS ~]#

  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@SOR_SYS ~]# cat /etc/issue

  Red Hat Enterprise Linux Server release 5.6 (Tikanga)

  Kernel \r on an \m

  [root@SOR_SYS ~]#

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

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

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

  [root@SOR_SYS ~]#

  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@SOR_SYS ~]# rpm -q redhat-release

  redhat-release-5Server-5.6.0.3

  [root@SOR_SYS ~]#

  注:这种方式下可看到一个所谓的release号,比如上边的例子是5

  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

  5) [root@SOR_SYS ~]# file /bin/bash

  /bin/bash: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped

  [root@SOR_SYS ~]#

  6) [root@SOR_SYS ~]# file /bin/cat

  /bin/cat: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped

  [root@SOR_SYS ~]#
