查看服务端口列表
方法1：
lsof -i:8080
方法2:
netstat -anp tcp|grep 8080
杀死进程：PID 占用端口号的进程ID
kill -9 PID
但是8080一般是nginx服务，使用ngnix停止命令更合适，清理更彻底：
回忆一下nginx安装：
nginx安装
brew install nginx
Docroot is: /opt/homebrew/var/www
The default port has been set in /opt/homebrew/etc/nginx/nginx.conf to 8080 so that nginx can run without sudo.
nginx will load all files in /opt/homebrew/etc/nginx/servers/.
启动nginx服务
nginx启动，保持后台运行：
To restart nginx after an upgrade:
brew services restart nginx
nginx前台运行的方式启动：
Or, if you don't want/need a background service you can just run:
/opt/homebrew/opt/nginx/bin/nginx -g daemon off;
停止nginx服务
brew services stop nginx
所以解决方法就是：
brew services stop nginx
