如何得知自己正在使用的linux是什么版本呢,下面的几种方法将给你带来答案!?
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 \r 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?
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。
