1. 檢視核心版本命令: 

1) [root@q1test01 ~]# cat /proc/version

linux version 2.6.9-22.elsmp ([email protected]) (gcc version 3.4.4 20050721 (red hat 3.4.4-2)) #1 smp mon sep 19 18:00:54 edt 2005

2) [root@q1test01 ~]# uname -a

linux q1test01 2.6.9-22.elsmp #1 smp mon sep 19 18:00:54 edt 2005 x86_64 x86_64 x86_64 gnu/linux

3) [root@q1test01 ~]# uname -r

2.6.9-22.elsmp

2. 檢視linux版本:

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

[[email protected] ~]# [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-

ia32:graphics-3.0-noarch

distributor id: redhatenterpriseas

description: red hat enterprise linux as release 4 (nahant update 2)

release: 4

codename: nahantupdate2

注: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/issue,例如如下:

[root@q1test01 ~]# cat /etc/issue

red hat enterprise linux as release 4 (nahant update 2)

kernel \r on an \m

3) 登入到linux執行cat /etc/redhat-release ,例如如下:

[root@q1test01 ~]# cat /etc/redhat-release

red hat enterprise linux as release 4 (nahant update 2)

注:這種方式下可以直接看到具體的版本號,比如 as4 update 1

4)登入到linux執行rpm -q redhat-release ,例如如下:

[root@q1test01 ~]# rpm -q redhat-release

redhat-release-4as-3

注:這種方式下可看到乙個所謂的release號,比如上邊的例子是3

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

另:第3)、4)兩種方法只對redhat linux有效
