檢視linux系統版本指令

一。檢視核心版本指令：

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

[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

二。檢視linux版本：

1) 登入到伺服器執行 lsb_release -a ,即可列出所有版本資訊,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

注:這個指令适用于所有的linux，包括Redhat、SuSE、Debian等發行版。

2) 登入到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

3) 登入到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)

注:這種方式下可以直接看到具體的版本号，比如 AS4 Update 1

4)登入到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

注:這種方式下可看到一個所謂的release号，比如上邊的例子是5

這個release号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)兩種方法隻對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

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
