Linux下查看版本号的命令

Linux下查看版本号的命令
1，查看内核版本命令：cat   /proc/versionuname   -auname   -rcat   /etc/issueman   uname2，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 -aLSB Version: 1.3Distributor ID: RedHatEnterpriseASDescrīption: Red Hat Enterprise Linux AS release 4 (Nahant Update 1)Release: 4Codename: 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-releaseRed 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 13）登录到linux执行rpm -q redhat-release ，例如如下[root@3.5.5Biz-46 ~]# rpm -q redhat-releaseredhat-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 3redhat-release-3AS-7.4 -> Redhat Enterprise Linux AS 3 Update 4redhat-release-4AS-2 -> Redhat Enterprise Linux AS 4redhat-release-4AS-2.4 -> Redhat Enterprise Linux AS 4 Update 1redhat-release-4AS-3 -> Redhat Enterprise Linux AS 4 Update 2redhat-release-4AS-4.1 -> Redhat Enterprise Linux AS 4 Update 3redhat-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
