1,查看内核版本命令: cat /proc/version uname -a uname -rcat /etc/issue man uname 2,查看linux版本:抄录如下: 1) 登录到服务器执行 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 Descrīption: Red Hat Enterprise Linux AS release 4 (Nahant Update 1) Release: 4 Codename: NahantUpdate1 [root@3.5.5Biz-46 ~]# 这个命令适用于所有的linux,包括Redhat、SuSE、Debian等发行版。 2) 登录到linux执行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 ~]# 这种方式下可以直接看到具体的版本号,比如 AS4 Update 1 3)登录到linux执行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 ~]# 这种方式下可看到一个所谓的release号,比如上边的例子是2.4 这个release号和实际的版本之间存在一定的对应关系,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)两种方法只对Redhat Linux有效
