查看Linux系統版本信息的命令詳解

  Linux系統下需要查看系統信息時使用命令是最快的方式。下面由學習啦小編為大家整理了查看Linux版本信息的命令詳解,希望對大家有幫助!

  查看Linux系統版本信息的命令詳解

  一、查看內核版本命令

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

  Linux version 2.6.18-238.el5 ([email protected]) (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) 登錄到服務器執行 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: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@SOR_SYS ~]# cat /etc/issue

  Red Hat Enterprise Linux Server release 5.6 (Tikanga)

  Kernel \r on an \m

  [root@SOR_SYS ~]#

  3) 登錄到linux執行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: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@SOR_SYS ~]# rpm -q redhat-release

  redhat-release-5Server-5.6.0.3

  [root@SOR_SYS ~]#

  注:這種方式下可看到一個所謂的release號,比如上邊的例子是5

  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

  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 ~]#
