虽然在安装软件的过程中，oracle会自动配置SSH对等性，建议在安装软件之前手工配置。
配置oracle用户对等性：
node1:
[root@node1 ~]# su - oracle node1-> env | grep ORA ORACLE_UNQNAME=devdb ORACLE_SID=devdb1 ORACLE_BASE=/u01/app/oracle ORACLE_HOSTNAME=node1.localdomain ORACLE_TERM=xterm ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 node1-> pwd /home/oracle node1-> mkdir ~/.ssh node1-> chmod 700 ~/.ssh node1-> ls -al total 44 drwx—— 4 oracle oinstall 4096 Apr 24 10:47 . drwxr-xr-x 4 root root 4096 Apr 24 09:41 .. -rw——- 1 oracle oinstall 5 Apr 24 10:43 .bash_history -rw-r–r– 1 oracle oinstall 33 Apr 24 09:41 .bash_logout -rw-r–r– 1 oracle oinstall 823 Apr 24 09:41 .bash_profile -rw-r–r– 1 oracle oinstall 124 Apr 24 09:41 .bashrc -rw-r–r– 1 oracle oinstall 515 Apr 24 09:41 .emacs drwxr-xr-x 4 oracle oinstall 4096 Apr 24 09:41 .mozilla drwx—— 2 oracle oinstall 4096 Apr 24 10:47 .ssh -rw-r–r– 1 oracle oinstall 658 Apr 24 09:41 .zshrc node1-> ssh-keygen -t rsa Generating public/private rsa key pair.
