安裝RAC做oracle集群件要求出現錯誤，錯誤信息如下：

1 [grid@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose 2 3 Performing pre-checks for cluster services setup 4 5 Checking node reachability... 6 7 Check: Node reachability from node "rac1" 8 Destination Node Reachable? 9 ------------------------------------ ------------------------ 10 rac2 yes 11 rac1 yes 12 Result: Node reachability check passed from node "rac1" 13 14 15 Checking user equivalence... 16 17 Check: User equivalence for user "grid" 18 Node Name Comment 19 ------------------------------------ ------------------------ 20 rac2 passed 21 rac1 failed 22 Result: PRVF-4007 : User equivalence check failed for user "grid"

一開始的思路是rac1 ssh rac2，rac2 ssh rac1；驗證通過后執行命令后還是報同樣的錯誤，代碼如下：

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

后來在論壇中發現一篇文章，里面提到，集群不僅要驗證對方，同時也要驗證自己：

1 [root@rac2 ~]# su - oracle 2 [oracle@rac2 ~]$ 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 6 Warning: Permanently added 'rac2' (RSA) to the list of known hosts. 7 Fri Aug 17 12:49:01 CST 2018 8 [oracle@rac2 ~]$ ssh rac2priv date 9 The authenticity of host 'rac2priv (172.16.0.92)' can't be established. 10 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15. 11 Are you sure you want to continue connecting (yes/no)? yes 12 Warning: Permanently added 'rac2priv,172.16.0.92' (RSA) to the list of known hosts. 13 Fri Aug 17 12:49:09 CST 2018 14 [oracle@rac2 ~]$ su - grid 15 Password: 16 [grid@rac2 ~]$ ssh rac2 date 17 The authenticity of host 'rac2 (127.0.0.1)' can't be established. 18 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15. 19 Are you sure you want to continue connecting (yes/no)? yes 20 Warning: Permanently added 'rac2' (RSA) to the list of known hosts. 21 grid@rac2's password: 22 Permission denied, please try again. 23 grid@rac2's password: 24 Fri Aug 17 12:49:33 CST 2018 25 [grid@rac2 ~]$ ssh rac2priv date 26 The authenticity of host 'rac2priv (172.16.0.92)' can't be established. 27 RSA key fingerprint is 00:38:d0:f8:99:20:fa:41:90:d6:9b:68:06:68:d8:15. 28 Are you sure you want to continue connecting (yes/no)? yes 29 Warning: Permanently added 'rac2priv,172.16.0.92' (RSA) to the list of known hosts. 30 grid@rac2priv's password: 31 Fri Aug 17 12:49:43 CST 2018

隨后再執行命令就全部pass（通過）。
