使用 DECLI 配置Exadata上cell节点的celladmin的信任关系

在Exadata上缺省没有配置cell节点的celladmin用户的信任关系，但是有时候我们需要用，那么手工配置一下吧。

借助dcli工具，使得配置很简单：

[celladmin@dm01cel01 ~]$ mkdir ~/.ssh
[celladmin@dm01cel01 ~]$ chmod 700 ~/.ssh
[celladmin@dm01cel01 ~]$ 

[celladmin@dm01cel02 ~]$ mkdir ~/.ssh
[celladmin@dm01cel02 ~]$ chmod 700 ~/.ssh
[celladmin@dm01cel02 ~]$ 

[root@dm01cel03 ~]# su - celladmin
[celladmin@dm01cel03 ~]$ mkdir ~/.ssh
[celladmin@dm01cel03 ~]$ chmod 700 ~/.ssh
[celladmin@dm01cel03 ~]$ 


[celladmin@dm01cel01 ~]$ cat cell.txt
dm01cel01
dm01cel02
dm01cel03
[celladmin@dm01cel01 ~]$ 

[celladmin@dm01cel01 ~]$ dcli -k -g cells.txt

[celladmin@dm01cel01 ~]$ 

[celladmin@dm01cel01 ~]$ ssh-keygen -t dsa
