1) 登入到伺服器執行 lsb_release -a ,即可列出所有版本資訊,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 ~]#

這個命令適用於所有的linux,包括Redhat、SuSE、Debian等發行版。

2) 登入到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碼,比如 AS4 Update 1

3)登入到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係,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
