安装grid之前检查配置 ，报错如下 ：

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

Performing pre-checks for cluster services setup

Checking node reachability...

Check: Node reachability from node "rac1"
  Destination Node                      Reachable?              
  ------------------------------------  ------------------------
  rac2                                  yes                     
  rac1                                  yes                     
Result: Node reachability check passed from node "rac1"


Checking user equivalence...

  rac2                                  failed                  
  rac1                                  failed                  
Result: PRVF-4007 : User equivalence check failed for user "grid"

ERROR:
User equivalence unavailable on all the specified nodes
Verification cannot proceed


Pre-check for cluster services setup was unsuccessful on all the nodes.

解决方法：

后来发现用ssh rac2 date的时候需要输入密码,这个好像不行,于是手工建立SSH用户等效性配置:

 rac1:

$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
$ ssh-keygen -t rsa
$ ssh-keygen -t dsa

rac2:

$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
$ ssh-keygen -t rsa
$ ssh-keygen -t dsa

rac1:
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys 
$ ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
$ scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys
