查看linux系统版本命令

查看linux系统版本命令

一、查看Linux内核版本命令
1.cat /proc/version
[root@localhost ~]# cat /proc/version Linux version 2.6.32-504.el6.i686 (mockbuild@c6b9.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) ) #1 SMP Wed Oct 15 03:02:07 UTC 2014 2.uname -a
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-504.el6.i686 #1 SMP Wed Oct 15 03:02:07 UTC 2014 i686 i686 i386 GNU/Linux

3.uname -r
[root@localhost ~]# uname -r
2.6.32-504.el6.i686

二、查看Linux系统版本的命令
1】cat /etc/redhat-release，这种方法只适合Redhat系的Linux：

[root@localhost ~]# cat /etc/redhat-release
CentOS release 6.6 (Final)

2】cat /etc/issue，此命令也适用于所有的Linux发行版。

[root@localhost ~]# cat /etc/issue
CentOS release 6.6 (Final)
Kernel \r on an \m

3】有安装红帽的用户执行结果：①登录到linux执行rpm -q redhat-release ,例如如下:[root@someone ~]# rpm -q redhat-release
redhat-release-5Server-5.6.0.3② 登录到服务器执行 lsb_release -a ,即可列出所有版本信息,例如:[root@someone ~]# lsb_release -a
LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch
Distributor ID: RedHatEnterpriseAS
Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
Release: 4
Codename: NahantUpdate4
这个命令适用于所有的Linux发行版，包括Redhat、SuSE、Debian…等发行版。我的没有安装红帽的效果：
