查看linux版本命令

1. 查看核心版本命令：   1) [root@q1test01 ~]# cat /proc/version    Linux version 2.6.9-22.ELsmp (bhcompile@crowe.devel.redhat.com) (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. 查看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:   [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-   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碼，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:這種方式下可看到一個所謂的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
