首先在服務器安全組添加3306放行端口
繼而再去面板中添加3306放行端口
在阿里雲服務器中登錄mysql進行遠程配置（權限為root才能配置，否則配置不成功）
1. 先用localhost登錄
# mysql -u root -p
Enter password:
2. 執行授權命令
mysql> grant all privileges on *.* to root@'%' identified by 'password'; 紅色底板的password自行設置
Query OK, 0 rows affected (0.07 sec)
3. 退出再試
mysql> quit
Bye
再試登錄：（這里測試用另一台主機（我這里用win10的cmd命令行連接）就能登錄，得先連網）
C:\Users\ASDS>mysql -uroot -h 主機ip -p 紅色底板的主機ip是要連接的數據庫的載體主機ip
Enter password: ********

第二種授權方式：
先在服務器數據庫中創建一個用戶和密碼：
mysql> create user geek identified by 'password';
Query OK, 0 rows affected (0.00 sec)
執行授權連接單獨的一個數據庫，我這里連接test數據庫：
mysql> grant all privileges on test.* to geek@'%';
Query OK, 0 rows affected (0.00 sec)
登錄測試：
C:\Users\ASDS>mysql -ugeek -h 128.10.2.64 -p
