基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境：4.安装Oracle RAC FAQ-4.3.Oracle 集群节点间连通失败

1.检查节点连通性的错误

[grid@linuxrac1 grid]$ ./runcluvfy.sh stage -post hwos -n linuxrac1,linuxrac2 -verbose

Performing post-checks for hardware and operating system setup

Checking node reachability...

Check: Node reachability from node "linuxrac1"

Destination Node                      Reachable?

------------------------------------  ------------------------

linuxrac1                             yes

linuxrac2                             yes

Result: Node reachability check passed from node "linuxrac1"

Checking user equivalence...

Check: User equivalence for user "grid"

Node Name                             Comment

------------------------------------  ------------------------

linuxrac2                             failed

linuxrac1                             failed

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

ERROR:

User equivalence unavailable on all the specified nodes

Verification cannot proceed

Post-check for hardware and operating system setup was unsuccessful on all the nodes.

[root@linuxrac1 Downloads]# scp root@10.10.97.161:/home/linuxrac1/Downloads/test.txt root@10.10.97.167:/home/linuxrac2/Downloads

Connection to 10.10.97.161 closed.

解决办法：重新配置用户等效性

1.首先通过执行ssh linuxrac1 date; ssh linuxrac2 date，检查用户等效性是否配置好，用户等效性配置成功的特点是，执行ssh linuxrac1 date后，直接显示节点的时间，不会提示输入密码：

[grid@linuxrac1 ~]$ ssh linuxrac1 date

Thu Sep 25 20:09:12 PDT 2014

[grid@linuxrac1 ~]$ ssh linuxrac1-priv date

Thu Sep 25 20:09:23 PDT 2014

[grid@linuxrac1 ~]$ ssh linuxrac2 date

Thu Sep 25 20:09:31 PDT 2014

[grid@linuxrac1 ~]$  ssh linuxrac2-priv date

Thu Sep 25 20:09:40 PDT 2014
