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 ~]# lsb_release -a
LSB Version: 1.3
Distributor ID: RedHatEnterpriseAS
Description: Red Hat Enterprise Linux AS release 4 (Nahant Update

[root@3.5.5Biz-46 ~]#
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:
[root@3.5.5Biz-46 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 1)
[root@3.5.5Biz-46 ~]#
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
[root@3.5.5Biz-46 ~]# rpm -q redhat-release
redhat-release-4AS-2.4
[root@3.5.5Biz-46 ~]#
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
