查看Linux系統版本主要采用哪些方法

1) 登錄到服務器執行 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

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

Release: 4

Codename: NahantUpdate1

[[email protected] ~]#

 這個命令適用於所有的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:  [[email protected] ~]# cat /etc/redhat-release

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

[[email protected] ~]#

 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

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

redhat-release-4AS-2.4

[[email protected] ~]#

 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
