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.
------解决方案--------------------
需要安装一个虚拟网卡，或回环网卡。
或将CentOS 5.4下网络配置好。
------解决方案--------------------
没有错误信息啊，没有关系，只是 是说要尽量配置一个静态IP，可以忽略
------解决方案--------------------
尽管忽略
------解决方案--------------------
你的ip地址如果是动态分配 这个提示就是正常的了
你改成静态的就可以通过了
但是也可以直接过去 不影响的
