查看linux系统版本命令

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_ x86_ x86_ 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-amd:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd: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 -bit LSB executable, AMD x86-, 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 -bit LSB executable, AMD x86-, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped [root@SOR_SYS ~]#
