方法一、docker pull mysql
查找Docker Hub上的mysql鏡像
#docker search mysql
這里我們拉取官方的鏡像,標簽為5.6
#docker pull mysql:5.6
（第一次啟動Docker-MySql主要是查看Docker里面MySQL的默認配置，數據位置，日志位置，配置文件位置）
#docker run -it --entrypoint /bin/bash --rm mysql:5.6 （創建並進入容器里，方便查看容器里面的默認設置，--rm參數表示退出容器會自動刪除當前容器） #cat /etc/mysql/mysql.cnf(查看默認配置文件)
（第二次啟動Docker-MySql）
#docker run --detach \
--publish 13306:3306 \ --restart always \ --volume /data/mysql/conf:/etc/mysql/conf.d \ --volume /data/mysql/mysqldata:/var/lib/mysql \ --volume /data/mysql/backup:/data/backup \ --volume /etc/localtime:/etc/localtime \ --env MYSQL_ROOT_PASSWORD=1234 \ mysql:5.6 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
停止容器，修改配置文件
#docker ps
#docker stop 4b6967498e1b
增加自定義配置文件，
vim /data/mysql/conf/my.cnf
my.cnf文件內容

重新啟動容器
#docker start 4b6967498e1b
進入容器，修改默認root用戶的Host為%，否則在容器外面登錄不進去mysql數據庫。
#docker exec -it 4b6967498e1b /bin/bash
重啟MySql服務
#service mysql restart
