oracle RAC手动配置互信

cd $ORACLE_HOME/sshsetup    grid的话是GI_HOME(一个节点上跑即可) ```sql ./sshUserSetup.sh -user oracle -hosts "vma vmb" -advanced -noPromptPassphrase ``` 集群（oracle,grid都要做） node1: ```sql [oracle @ node1~]$ ssh-keygen -t rsa                //一路回车 [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                //一路回车 [oracle @ node2~]$ ssh-keygen -t dsa ``` node1: ```sql [oracle @ node1 .ssh]$ scp authorized_keys node2:/home/oracle/.ssh/         //选yes  输入二节点oracle用户密码 ``` node2: ```sql [oracle @ node2~]$ cd .ssh [oracle @ node2 .ssh]$ cat *.pub >> authorized_keys [oracle @ node2 .ssh]$ scp authorized_keys node1:/home/oracle/.ssh/ ```
