1.问题闪现:
[email protected]:~/Work/Learning/Docker/docker_compose$ docker-compose up -d
myshop_tomcat is up-to-date
Starting myshop_mysql ...
myshop_redis is up-to-date
Starting myshop_mysql ... error

2.尝试解决手段：
[email protected]:~/Work/Learning/Docker/docker_compose$ netstat -apn | grep 3306
(并非所有进程都能被检测到，所有非本用户的进程信息将不会显示，如果想看到所有信息，则必须切换到 root 用户)
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN -
[email protected]:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 3306
[sudo] yunduo 的密码：

mysqld杀不死！！！
2.彻底解决手段：
一旦运行MySQL镜像，MySQL 服务器自启动，ubuntu下彻底停止mysql：sudo /etc/init.d/mysql stop
#ubuntu下彻底停止mysql
[email protected]:~/Work/Learning/Docker/docker_compose$ sudo /etc/init.d/mysql stop
[ ok ] Stopping mysql (via systemctl): mysql.service.
#查看3306端口是否还在占用
[email protected]:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 3306
[email protected]:~/Work/Learning/Docker/docker_compose$ docker-compose up -d
