首先，准备好网络、主机名、存储等相关配置，以下会跳过相关程度不大的步骤

2.4 创建用户和组

要确保每个节点的用户和组有相同的UID和GID

1. groupadd oinstall
   
2. groupadd dba
   
3. groupadd oper
   
4. 
   
5. useradd -u 200 -g oinstall -G dba,oper oracle
   
6. 
   
7. passwd oracle

配置用户等效性

以oracle用户登录

点击(此处)折叠或打开

1. mkdir ~/.ssh
   
2. chmod 700 ~/.ssh
   
3. 
   
4. ssh-keygen -t rsa
   
5. 
   
6. ssh-keygen -t dsa
   
7. 
   
8. #在所有节点完成后继续以下
9. touch ~/.ssh/authorized_keys
   
10. cd ~/.ssh
    
11. ssh node1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
    
12. 
    
13. ssh node1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
    
14. ssh node2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
    
15. 
    
16. ssh node2 cat /home/oracle/.ssh/id_dsa.pub >>authorized_keys
    
17. 
    
18. scp authorized_keys node2:/home/oracle/.ssh/

在所有节点上配置完后，验证：
