在linux上维护了很久了,今天居然不知道怎么看linux的版本,搜索了下记录于此:
1. 查看内核版本命令:
1) [root@q1test01 ~]# cat /proc/version
Linux version 2.6.9-22.ELsmp (bhcompile@crowe.devel.redhat.com) (gcc version 3.4.4 20050721 (Red Hat 3.4.4-2))
#1 SMP Mon Sep 19 18:00:54 EDT 2005
2) [root@q1test01 ~]# uname -a
Linux q1test01 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:00:54 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux 3) [root@q1test01 ~]# uname -r 2.6.9-22.ELsmp
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: [root@3.5.5Biz-46 ~]# [root@q1test01 ~]# lsb_release -a
LSB Version: :core-3.0-amd64:core-3.0-ia32:core-3.0-noarch:graphics-3.0-amd64:graphics-3.0-ia32:graphics-3.0-noarch
Distributor ID: RedHatEnterpriseAS
Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 2) Release: 4
Codename: NahantUpdate2
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@q1test01 ~]# cat /etc/issue
Red Hat Enterprise Linux AS release 4 (Nahant Update 2) Kernel on an m
3) 登录到Linux执行cat /etc/redhat-release ,例如如下:
[root@q1test01 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 2)
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@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 Codename: NahantUpdate2
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@q1test01 ~]# cat /etc/issue Red Hat Enterprise Linux AS release 4 (Nahant Update
2) Kernel on an m
3) 登录到Linux执行cat /etc/redhat-release ,例如如下:
[root@q1test01 ~]# cat /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 2)
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@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
