查看Linux发行版本
lsb_release -a命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版。
[[email protected]3.5.5Biz-46 ~]# 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] ~]# lsb_release -a LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 6.5 (Final) Release: 6.5 Codename: Final
对于Redhat 和其派生出的发行版, 例如 Centos, 使用 cat /etc/redhat-release, 这种方式下可以直接看到具体的版本号，比如 AS4 Update 1
[[email protected]3.5.5Biz-46 ~]# cat /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 1) [[email protected] ~]# cat /etc/redhat-release CentOS release 6.5 (Final)
对于Redhat 使用 rpm -q redhat-release
[[email protected]3.5.5Biz-46 ~]# rpm -q redhat-release redhat-release-4AS-2.4
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
