1、查询 mysql

docker search mysql

[root@iz2zei0x4t16rv0e5buzvhz /]# docker search mysql

2、安装 mysql

关键命令：

docker run -p 3306:3306 --name mysql \
-v /mysoft/mysql/conf/:/etc/mysql/conf.d/    \
-v /mysoft/mysql/logs:/logs  \
-v /mysoft/mysql/data:/var/lib/mysql   \
-e MYSQL_ROOT_PASSWORD=123456  \
-d mysql:5.7
--character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

3、查看 mysql 进程

[root@iz2zei0x4t16rv0e5buzvhz /]# docker ps
CONTAINER ID        IMAGE          COMMAND                  CREATED          STATUS     PORTS                                              NAMES
84694b113c10        mysql:5.7      "docker-entrypoint.s…"   7 seconds ago       Up 5 seconds     0.0.0.0:3306->3306/tcp, 33060/tcp               mysql      

4、登录 mysql server

[root@iz2zei0x4t16rv0e5buzvhz /]# docker exec -it 84694b113c10 /bin/bash
root@84694b113c10:/# mysql -uroot -p

4、设置防水墙

因为使用的是阿里云轻应用服务器，添加端口号：

5、mysql 客户端 SQLyog 登录

6、乱码问题

https://blog.csdn.net/m0_37639542/article/details/72852875

我遇到乱码问题

mysql> select * from student;
+----+--------+------+---------------------+---------------------+--------+
| id | name   | age  | create_time         | update_time         | remark |
+----+--------+------+---------------------+---------------------+--------+
|  1 | ?? |   20 | 2018-12-13 10:10:05 | 2018-12-13 10:10:08 |        |
|  2 | ?? |   30 | 2018-12-13 10:10:15 | 2018-12-13 10:10:17 |        |
+----+--------+------+---------------------+---------------------+--------+

解决方法：
1、查看是否是utf8 ，或 utf8mb4

mysql>SHOW VARIABLES LIKE 'character_set_%';//查看数据库字符集

mysql>SSHOW VARIABLES LIKE 'collation_%';

2、设置编码方式

SET NAMES 'utf8';

3、再次查询

mysql> select * from student;
+----+--------+------+---------------------+---------------------+--------+
| id | name   | age  | create_time         | update_time         | remark |
+----+--------+------+---------------------+---------------------+--------+

|  2 | 李四 |   30 | 2018-12-13 10:10:15 | 2018-12-13 10:10:17 |        |
