几种查看linux版本信息的方法:
- uname -a
- cat /proc/version
- cat /etc/issue
- lsb_release -a
详解 lsb_release -a
- 登录到服务器执行 lsb_release -a ,即可列出所有版本信息,例如:
这个命令适用于所有的linux,包括Redhat、SuSE、Debian等发行版。- [root@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
- [root@3.5.5Biz-46 ~]#
- [root@3.5.5Biz-46 ~]# lsb_release -a
- 登录到linux执行cat /etc/redhat-release ,例如如下:
这种方式下可以直接看到具体的版本号,比如 AS4 Update 1- [root@3.5.5Biz-46 ~]# cat /etc/redhat-release
- Red Hat Enterprise Linux AS release 4 (Nahant Update 1)
- [root@3.5.5Biz-46 ~]#
- [root@3.5.5Biz-46 ~]# cat /etc/redhat-release
- 登录到linux执行rpm -q redhat-release ,例如如下
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- [root@3.5.5Biz-46 ~]# rpm -q redhat-release
- redhat-release-4AS-2.4
- [root@3.5.5Biz-46 ~]#
这个release号和实际的版本之间存在一定的对应关系,如下:
注意:第2、3两种方法只对Redhat Linux有效- 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
- [root@3.5.5Biz-46 ~]# rpm -q redhat-release
