openSUSE下如何查看Linux版本

1. 查看内核版本命令：
1) linux-zopi:~ # cat /proc/version

Linux version 2.6.37.1-1.2-desktop (geeko@buildhost) (gcc version 4.5.1 20101208 [gcc-4_5-branch revision 167585] (SUSE Linux) ) #1 SMP PREEMPT 2011-02-21 10:34:10 +0100

2) linux-zopi:~ # uname -a

Linux linux-zopi 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 i686 i686 i386 GNU/Linux

3) linux-zopi:~ # uname -r

2.6.37.1-1.2-desktop

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，如:

linux-zopi:~ # lsb_release -a

LSB Version: n/a

Distributor ID: SUSE LINUX

Description: openSUSE 11.4 (i586)

Release: 11.4

Codename: Celadon

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，如:

linux-zopi:~ # cat /etc/issue

Welcome to openSUSE 11.4 "Celadon" - Kernel \r (\l).

3) 登录到linux执行cat /etc/SuSE-release，如:

linux-zopi:~ # cat /etc/SuSE-release

openSUSE 11.4 (i586)

VERSION = 11.4

CODENAME = Celadon

注:在RedHat中此命令为“cat /etc/redhat-release”。

另外在Redhat Linux中还有如下查询命令：

4) 登录到linux执行rpm -q redhat-release，如:

[root@q1test01 ~]# rpm -q redhat-release

redhat-release-4AS-3

注:这种方式下可看到一个所谓的release号，比如上边的例子是3

　　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
