1) 登錄到服務器執行 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 1) Release: 4 Codename: NahantUpdate1 [root@3.5.5Biz-46 ~]# 這個命令適用于所有的linux，包括Redhat、SuSE、Debian等發行版。 2) 登錄到linux執行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 ~]# 這種方式下可以直接看到具體的版本號，比如 AS4 Update 1 3）登錄到linux執行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 ~]# 這種方式下可看到一個所謂的release號，比如上邊的例子是2.4 這個release號和實際的版本之間存在一定的對應關系，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）兩種方法只對Redhat Linux有效
