2. 運行
[root@localhost my.Shells]# docker run --name docker-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=wzy123 -d mysql //用戶默認是root，密碼默認是root的密碼 283a1fa17fef310d9e329e11f10b8179e5be5fd88310be64fb0b4fa75ab5d80f [root@localhost my.Shells]# docker ps //mysql容器已經啟動了 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 283a1fa17fef mysql "docker-entrypoint.sh" 7 seconds ago Up 6 seconds 0.0.0.0:3306->3306/tcp docker-mysql

1.工具登錄
2.命令行登錄 [root@localhost my.Shells]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 283a1fa17fef mysql "docker-entrypoint.sh" 18 hours ago Up 3 seconds 0.0.0.0:3306->3306/tcp docker-mysql [root@localhost my.Shells]# docker exec -it docker-mysql bash root@283a1fa17fef:/# ls bin boot dev docker-entrypoint-initdb.d entrypoint.sh etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var root@283a1fa17fef:/# mysql -u root -p Enter password: //wzy123 Welcome to the MySQL monitor.

注意：當使用docker rm [id]后，mysql數據庫的所有數據會全部清除，再重新開啟一個鏡像是一個嶄新的數據庫。
mysql 遠程連接數據庫的二種方法
一、連接遠程數據庫：
1、顯示密碼
如：MySQL 連接遠程數據庫（192.168.5.116），端口“3306”，用戶名為“root”，密碼“123456”
C:/>mysql -h 192.168.5.116 -P 3306 -u root -p123456
2、隱藏密碼
如：MySQL 連接本地數據庫，用戶名為“root”，
C:/>mysql -h localhost -u root -p
Enter password:
Enter password:
二、配置mysql允許遠程鏈接
默認情況下，mysql帳號不允許從遠程登陸，只能在localhost登錄。本文提供了二種方法設置mysql可以通過遠程主機進行連接。
一、改表法
在localhost登入mysql后，更改 "mysql" 數據庫里的 "user" 表里的 "host" 項，將"localhost"改稱"%"
例如：
#mysql -u root -p
Enter password:
……
mysql>
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
二、授權法
例如： 你想myuser使用mypassword（密碼）從任何主機連接到mysql服務器的話。
mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允許用戶myuser從ip為192.168.1.6的主機連接到mysql服務器，並使用mypassword作為密碼
mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3'IDENTIFIED BY
'mypassword' WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES
使修改生效，就可以了
常見問題：
1、在采用法二授權法之后，無法在本地登錄mysql（如：#mysql -u root -p -h 192.168.5.116
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'loadb116' (using password: YES)
上例中loadb116是主機名.
解決方法：
1、這時可以使用：mysql -u root -p 登錄，進入到mysql后。
mysql> grant all privileges on *.* to 'root'@'loadb116'
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)
2、在本地使用ip地址登錄
# mysql -u root -p -h 192.168.5.116
Enter password:
