正確的啟動 [[email protected] ~]# docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql b874c56bec49fb43024b3805ab51e9097da779f2f572c22c695305dedd684c5f [[email protected] ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b874c56bec49 mysql "docker-entrypoint.sh" 4 seconds ago Up 3 seconds 3306/tcp
做了埠對映 [[email protected] ~]# docker run -p 3306:3306 --name mysql02 -e MYSQL_ROOT_PASSWORD=123456 -d mysql ad10e4bc5c6a0f61cbad43898de71d366117d120e39db651844c0e73863b9434 [[email protected] ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ad10e4bc5c6a mysql "docker-entrypoint.sh" 4 seconds ago Up 2 seconds 0.0.0.0:3306->3306/tcp my

執行這一步操作後就可以連線navicate進行資料庫操作了。
