oracle RAC手動配置互信

cd $ORACLE_HOME/sshsetup  

 grid的話是GI_HOME(一個節點上跑即可)

```sql

./sshUserSetup.sh -user oracle -hosts "vma vmb" -advanced -noPromptPassphrase

```

叢集（oracle,grid都要做）

node1:

```sql

[oracle @ node1~]$ ssh-keygen -t rsa                //一路回車

[oracle @ node1~]$ ssh-keygen -t dsa

[oracle @ node1~]$ cd .ssh

[oracle @ node1.ssh]$ cat *.pub > authorized_keys

```

    

node2:

```sql

[oracle @ node2~]$ ssh-keygen -t rsa                //一路回車

[oracle @ node2~]$ ssh-keygen -t dsa

```

node1:

```sql

[oracle @ node1 .ssh]$ scp authorized_keys node2:/home/oracle/.ssh/        

//選yes  輸入二節點oracle使用者密碼

```

node2:

```sql

[oracle @ node2~]$ cd .ssh

[oracle @ node2 .ssh]$ cat *.pub >> authorized_keys

[oracle @ node2 .ssh]$ scp authorized_keys node1:/home/oracle/.ssh/

```
