1.問題閃現:

myshop_tomcat is up-to-date

2.嘗試解決手段：
[email protected]:~/Work/Learning/Docker/docker_compose$ netstat -apn | grep 3306
(并非所有程序都能被檢測到，所有非本使用者的程序資訊将不會顯示，如果想看到所有資訊，則必須切換到 root 使用者)
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 的密碼：

mysqld殺不死！！！
2.徹底解決手段：
一旦運作MySQL鏡像，MySQL 伺服器自啟動，ubuntu下徹底停止mysql：sudo /etc/init.d/mysql stop
#ubuntu下徹底停止mysql
[email protected]:~/Work/Learning/Docker/docker_compose$ sudo /etc/init.d/mysql stop
[ ok ] Stopping mysql (via systemctl): mysql.service.
#檢視3306端口是否還在占用
[email protected]:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 3306
[email protected]:~/Work/Learning/Docker/docker_compose$ docker-compose up -d
