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

原因：

1、主机名没有配置,使用localhost;
2、没有配置IP
3、HOSTS 配置问题
4、DNS问题
