【Docker】安装MySQL彻底解决3306端口占用问题

1.问题闪现:

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 myshop_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: 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：

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

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     
yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ kill -9 9727
bash: kill: (9727) - 不允许的操作
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     
yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ sudo kill -9 9727

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     
yunduo@YunDuo:~/Work/Learning/Docker/docker_compose$ sudo netstat -apn | grep 6623
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      6623/mysqld     
unix  2      [ ACC ]     流        LISTENING     15031431 6623/mysqld         /var/run/mysqld/mysqld.sock

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
