其实rac已经安装好了，我使用cluvfy命令时发现一个有意思的问题(安装前需要使用runcluvfy来验证，因为cluvfy命令还没有被安装进来），安装crs之后cluvfy就可以正常使用了。[@more@]

通过root验证失败，错误提示主要是：Result: Membership check for user "root" in group "oinstall" [as Primary] failed.原因就是说oinstall组不是root用户的主组，执行下面命令把root加到oinstall和dba组里：

# usermod -G root,oinstall,dba -U root

并且root用户注销之后：

[root@node1 ~]# groups
root oinstall dba
[root@node1 ~]#

很显然oinstall已经是root用户的Primary组了，但是依然验证不成功。

[root@node1 ~]# cluvfy stage -pre crsinst -n node1,node2 -verbose
