今天是第二次安装RAC,但是遇到了一个很奇怪的问题,这里写下来,防止以后发生类似的问题。
环境是:在Vmware Workstation 8上安装两个CentOS4.4 ,并配置好网络,NTP,RAW,SSH以及参数等等。但是在检查用户等价时总是提示失败,我也到网站上找了好几篇文章来看,可以还是没能解决,后来也按照ORACLE官方文档来做了,但是还是失败,郁闷了半天,但是最后还是解决了,哎,其实这个真的不是问题啊,其他的文件都检查了,就把这个个给遗漏了,做了大量无用的工作,最后还是回到了原点,哈哈。
错误提示如下:

处理如下:
检查了SSH没问题
检查了网络没问题,都可以正常通信
检查了安装包
但是问题依然存在,最近看了service ntpd status 都是stop的状态,原来问题是出在这里
把ntp服务重新启动后,检查通过,顺利安装crs软件。
最后总结:
1。时间必须同步
2。public网卡的ip一定要记得设置网关,保证网关能ping通
3。保证ssh互信
4。需要的安装包都装上
