MacOS安装nginx，启动、重启、关闭

brew install nginx

Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

To have launchd start nginx now and restart at login:
brew services start nginx
Or, if you don't want/need a background service you can just run:
nginx

nginx配置文件目录：
/usr/local/etc/nginx/nginx.conf

启动nginx：
ngxin

重启nginx：
nginx -s reload

关闭/停止nginx：
先查询nginx对应端口号
ps -ef | grep nginx
