如何查看Linux操作系统版本?

1. 查看内核版本命令:

chen@mylinuxserver:~> cat /proc/version

Linux version 2.6.5-7.244-smp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Mon Dec 12 18:32:25 UTC 2005

/proc 目录的作用?

chen@mylinuxserver:/proc> uname -a

Linux mylinuxserver 2.6.5-7.244-smp #1 SMP Mon Dec 12 18:32:25 UTC 2005 i686 i686 i386 GNU/Linux

chen@mylinuxserver:/proc> uname -r

2.6.5-7.244-smp

uname命令的作用?

2. 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:

chen@mylinuxserver:/proc> lsb_release -a

LSB Version:    core-2.0-noarch:core-3.0-noarch:core-2.0-ia32:core-3.0-ia32:graphics-2.0-ia32:graphics-2.0-noarch:graphics-3.0-ia32:graphics-3.0-noarch

Distributor ID: SUSE LINUX

Description:    SUSE LINUX Enterprise Server 9 (i586)

Release:        9

Codename:       n/a

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:

chen@mylinuxserver:/proc> cat /etc/issue

Welcome to SUSE LINUX Enterprise Server 9 (i586) - Kernel \r (\l).

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

chen@mylinuxserver:/proc> cat /etc/*release*

LSB_VERSION="core-2.0-noarch:core-3.0-noarch:core-2.0-ia32:core-3.0-ia32"

cat: /etc/lsb-release.d: 是一个目录

SUSE LINUX Enterprise Server 9 (i586)

VERSION = 9
