Linux下查看版本号的命令

1，查看内核版本命令：

cat   /proc/version

uname   -a

uname   -rcat   /etc/issue

man   uname

2，查看linux版本：抄录如下：

1) 登录到服务器执行 lsb_release -a ，即可列出所有版本信息，例如：



[[email protected] ~]# lsb_release -a

LSB Version: 1.3

Distributor ID: RedHatEnterpriseAS

Descrīption: Red Hat Enterprise Linux AS release 4 (Nahant Update 1)

Release: 4

Codename: NahantUpdate1

[[email protected] ~]#



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/redhat-release ，例如如下：

[[email protected] ~]# cat /etc/redhat-release

Red Hat Enterprise Linux AS release 4 (Nahant Update 1)

[[email protected] ~]#



这种方式下可以直接看到具体的版本号，比如 AS4 Update 1



3）登录到linux执行rpm -q redhat-release ，例如如下



[[email protected] ~]# rpm -q redhat-release

redhat-release-4AS-2.4

[[email protected] ~]#



这种方式下可看到一个所谓的release号，比如上边的例子是2.4

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



注意：第（2）（3）两种方法只对Redhat Linux有效
