【RAC】11gR2 RAC安装中的Task resolv.conf Integrity问题

Roderick

这两天我在虚拟机OEL5.7 Linux环境装RAC时，一直未解决Prerequisite Checks的Task resolv.conf Integrity问题。请各位赐教！

版本：Oracle Database 11g R2（11.2.0.3）

Host环境：
Win7 SP1 x64 + VirtualBox 4.1.2

Guest环境：
两个主机rac1，rac2各配置2个网卡，皆以Bridged Adapter方式以Host的以太网卡相连。
系统： Oracle Enterprise Linux 5.7

在安装grid中的Prerequisite Checks步骤遇到Task resolv.conf Integrity问题一直未能解决。

用cluvfy进行检查，./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose发现如下问题（其它皆已passed，输出省略）：

你好

如果没有配置DNS的话 检测/etc/resolv.conf 这步骤是会失败的， 但是不影响安装 ，直接 ignore 即可
