在Linux上安装Oracle的时候，出现以下错误提示：

wanning:

CheckingNetworkConfiguration 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 OracleSoftware to function properly.See the
InstallationGuidefor 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
2.HOSTS 文件不匹配或不对
3.主机名为localhost
4没有配置DNS
5:修改了主机名后
点击retry 通过了 ，不用重启机器。
　　注:修改主机名方法

　　hostname oracleServer
 　　vi /etc/sysconfig/network  ---修改hostnamehostaname = oracleServer.localdimain
　　 vi /etc/hosts    -- 增加192.168.1.99  oracleServer.localdimain
 　　这里一定要将主机名设置为xxx.xxx的网络主机名形式
