環境：mysql執行在阿里雲ECS的dokcer裡面

1. docker ps -a 發現mysql執行正常

[root@hadoop101 ~]# docker ps -a

進入mysql檢視是否存在資料庫jeesite

2. docker exec -it mysql bash

　　mysql -u root -p

mysql> show databases;
+--------------------+
| Database           |

| information_schema |
| jeesite            |

| performance_schema |
| sys                |
+--------------------+
5
 
 rows in set (0.00 sec)

3. netstat -tlnp #發現3306埠也開著

[root@hadoop101 ~]# netstat -tlnp
Active Internet connections (only servers)

[root@hadoop101 ~]# docker exec -it mysql bash

4. Navicat for mysql也能連線成功

5. 執行init-data.sh報錯如下：

　　init datasource error:jdbc....

6. 到處都是正常的，最後發現是阿里雲安全組裡面的3306埠沒有配，配完了再執行就成功了
