正确的启动 [[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
做了端口映射 [[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
当关闭后想要再次启动 首先要知道你做了容器映射后的id 找到指定的id，就可以启动容器了
[[email protected] ~]# docker ps -a /etc/sysconfig/docker: line 4: PTIONS: command not found /etc/sysconfig/docker: line 5: /bin/bash:: No such file or directory CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 707b4adac44f mysql "docker-entrypoint..."

执行这一步操作后就可以连接navicate进行数据库操作了。
