Oracle-RAC等价性验证错误：Result: PRVF-4007 : User equivalen

安装RAC做oracle集群件要求出现错误，错误信息如下：

 1 [[email?protected] grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

 3 Performing pre-checks for cluster services setup

22 Result: PRVF-4007 : User equivalence check failed for user "grid"

一开始的思路是rac1 ssh rac2，rac2 ssh rac1；验证通过后执行命令后还是报同样的错误，代码如下：

1 ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose

后来在论坛中发现一篇文章，里面提到，集群不仅要验证对方，同时也要验证自己：

 1 [[email?protected] ~]# su - oracle
 2 [[email?protected] ~]$ ssh rac2 date
 3 The authenticity of host ‘rac2 (127.0.0.1)‘ can‘t be established.
 4 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15.
 5 Are you sure you want to continue connecting (yes/no)? yes

随后再执行命令就全部pass（通过）。
