1.问题闪现:###

初次up mysql报3306端口被占用

yunduo@YunDuo:~/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

ERROR: for mysql Cannot start service mysql: driver failed programming external connectivity on endpoint myshop_mysql (c42794af6a45ae1f176660abcd493c6c6345ddaec5c30ac84761e75cd3848484): Error starting userland proxy: listen tcp 0.0.0.0:3306: bind: address already in use

ERROR: Encountered errors while bringing up the project.

2.尝试解决手段：###

杀死占用对应端口进程

yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 3306

tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 9727/mysqld

#kill3306端口占用的进程

yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ sudo kill -9 9727

#再次查询发现3306端口还是被占用

yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 3306

tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 6623/mysqld

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

yunduo@YunDuo:~/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

yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 3306

yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ docker-compose up -d

myshop_redis is up-to-date

Starting myshop_mysql ...

Starting myshop_mysql ... done

yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ docker ps
