一直没安装过11G，这几天没事想玩玩11G，心想玩单机的太没意思，于是直接在虚拟机环境搭11G RAC环境，在网上下了点资料，看了些博客就开始做了，但在安装Oracle Grid Infrastructure时，第二个节点执行root.sh报错，这个问题困扰了我两天了

在百度里找半天都没找到什么有用的东西，后来在google 上找到答案了

原来是自己犯了点小错误，以后大家遇到这个问题也可以做个参考，检查一下/etc/hosts的配置

因为我是先做好一台虚拟机，然后直接拷过去用的，结果/etc/hosts中127.0.0.1这一行忘记改了，还是对应的第一台主机的主机名，如127.0.0.1 racdb01 localhost.localdomain localhost

将它改成127.0.0.1 racdb02 localhost.localdomain localhost

就可以了，真是发狂，拷到另一台主机后需要改的配置很多，那么多都没改错，居然在这犯这种低级错误。改过之后再

/app/product/grid/11.2.0/crs/install/roothas.pl -delete -force -verbose
/app/product/grid/11.2.0/root.sh

一切OK了
