查看Linux版本信息

如何查看Linux系统使用的版本信息呢？下面这篇文章收集、整理了一些常见的查看Linux系统版本的方法。由于手头只有Oracle Linux、Centos Linux、Redhat Linux三个版本Linux，所以像Debian、Ubuntu之类的Linux系统,下面方法在这些版本都没测试过。

   [root@DB-Server ~]# more /etc/issue 
   Oracle Linux Server release 5.7 
   Kernel \r on an \m

1.2 Centos Linux

 
   [root@Centos2 ~]# more /etc/issue 
   CentOS release 6.4 (Final) 
   Kernel \r on an \m 
  

1.3 RedHat Linux

 
   [root@getlnx05 ~]# more /etc/issue 
   Red Hat Enterprise Linux Server release 5.7 (Tikanga) 
   Kernel \r on an \m 
  

2: lsb_release -a 命令查看
