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。

1.1 Oracle Linux

[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
