.下载mysql镜像
sudo docker pull mysql:laster

2.列出本地镜像

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7

参数说明
-p 3306:3306：将容器的 3306 端口映射到主机的 3306 端口
-v /mydata/mysql/conf:/etc/mysql：将配置文件夹挂载到主机
-v /mydata/mysql/log:/var/log/mysql：将日志文件夹挂载到主机
-v /mydata/mysql/data:/var/lib/mysql/：将配置文件夹挂载到主机
-e MYSQL_ROOT_PASSWORD=root：初始化 root 用户的密码

4.查看
docker ps

5.配置
vi /mydata/mysql/conf/my.cnf

按i

[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

注意：解决 MySQL 连接慢的问题
在配置文件中加入如下，并重启 mysql
[mysqld]
skip-name-resolve
解释：
skip-name-resolve：跳过域名解析
