Oracle 11g RAC安装时，，在第一个节点执行root.sh时遭遇了CRS-0184/PRCR-1070，Google了很多帖子也没有找到解决办法。呜呜，还是静下心来看日志！！最后的发现原来是一个不经意的小问题，如下面的描述。

1、故障现象

#安装环境
[root@linux1 ~]# more /etc/issue
Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)
Kernel \r on an \m

[root@linux1 ~]# uname -a

[root@linux1 bin]# ./crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.1.0]

#执行root时，出现了下面的错误，仅列出错误部分
CRS-0184: Cannot communicate with the CRS daemon. #这个是主要的错误提示，不能同crs通信

#使用crsctl check时收到了crs-4535错误
[root@linux1 bin]# ./crsctl check cluster

2、分析日志

#查看grid的crsd部分的日志，注意该日志位于$CRS_HOME/log/node_name/crsd
[root@linux1 crsd]# tail -30 crsdOUT.log

# Meatlink [ID 1230899.1] 有关于该问题的描述，就是需要添加localhost到hosts文件
# Author : Robinson
# Blog :

3、解决故障

#查看本地的hosts文件，下面是更改后的hosts配置文件
[root@linux1 bin]# more /etc/hosts | grep 127.0
#127.0.0.1 linux1.orasrv.com linux1 localhost.localdomain localhost #这个是安装OS时自动生成的
#127.0.0.1 linux1.orasrv.com linux1 #这个是安装rac之前配置的，看来这个写法有问题，一定要写localhost
127.0.0.1 localhost.orasrv.com localhost #添加一个新的关于localhost的解析entry

#尝试启动crs
[root@linux1 bin]# ./crsctl start res ora.crsd -init
CRS-2672: Attempting to start 'ora.crsd' on 'linux1'
CRS-2676: Start of 'ora.crsd' on 'linux1' succeeded
