3.查詢mysql鏡像
查詢鏡像命令：docker images
刪除鏡像命令：docker rmi <image id>
4.用docker啓動mysql容器
啓動命令：docker run --name mysql5.6 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6
命令解析：
--name：容器名
--p：映射宿主主機端口
-v：掛載宿主目錄到容器目錄
-e：設置環境變量，此處指定root密碼
-d：後臺運行容器
mysql:5.6 爲鏡像名稱和tag版本，如果是最新版本後綴可忽略
localhost:~ zhangjiankang$ docker run --name mysql5.6 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6
