Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with
DHCP-assigned public IP addresses. However, the primary network
interface on the system should be configured with a static IP address in
order for the Oracle Software to function properly. See the
Installation Guide for more details on installing the software on
systems configured with DHCP
可能造成原因：
1.地址是动态分配的，但是大多数人是静态设置的
2.HOSTS 文件不匹配或不对
3.主机名为localhost
4没有配置DNS
注意：修改了主机名后
hostname oracle
vi /etc/sysconfig/network
hostaname = oracle
vi /etc/hosts
ip oracle
点击retry 通过了 ，不用重启机器
不信你试试
