? 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-?

? 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-4.1 -> Redhat Enterprise Linux AS 4 Update 3?
?
? redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4?
