首先，這個連線方法，有個缺點，就是特別慢，暫時沒有找到解決方法，找到咯在補上。哪位猿友知道的，麻煩給我留個連線哈~

一、首先要mysql授權

    mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;  
    Query OK, 0 rows affected (0.00 sec)  
      
    mysql>FLUSH PRIVILEGES;  
    Query OK, 0 rows affected (0.00 sec)  

mysql> select host,user from user;  
+-------------------------+------+  
| host                    | user |  
+-------------------------+------+  
| %                       | root |  
| 127.0.0.1               | root |  
| iz2ze3hkpeilimy9kn68tvz |      |  
| iz2ze3hkpeilimy9kn68tvz | root |  
| localhost               |      |  
| localhost               | root |  
+-------------------------+------+  
6 rows in set (0.00 sec) 
 

說明:[修改許可權後查詢user表 ]

二、Navicat遠端連線阿里雲ECS資料庫

2、進行SSH設定
