关于如题所示的报错的完整输出场景如下:

产生这个错误的原因是因为你没有完整的配完SSH等价关系:

你可以这么操作,解决这个问题:

测试下是否真的解决这个问题了:

这样就可以了。

按照上面的操作,在RAC的各个节点上对grid和oracle都作出一样的操作。
注意:对于新增的节点rac3来说,他需要对grid和oracle,做到所有节点的IP和私有IP的等价关系。
建立方法和上面也是一样的:
ssh-copy-id -i .ssh/id_rsa.pub rac1
ssh-copy-id -i .ssh/id_rsa.pub rac1-priv

ssh-copy-id -i .ssh/id_rsa.pub rac2
ssh-copy-id -i .ssh/id_rsa.pub rac2-priv

ssh-copy-id -i .ssh/id_rsa.pub rac3
ssh-copy-id -i .ssh/id_rsa.pub rac3-priv

——————————
Done。
