安装：
brew install nginx
以下是安装完成之后打印出来的提示信息
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 nginxOr, if you don't want/need a background service you can just run: nginx
按照提示启动
brew services start nginx
查看状态：
nginx -t
如果报错
nginx: [emerg] open() "/usr/local/var/run/nginx.pid" failed (13: Permission denied)
权限问题
sudo chown -R $(whoami) /usr/local/var/run # 具体路径参考报错提示中的路径
重启nginx服务器
brew services stop nginx # 停止brew services start nginx # 启动
提示中默认显示8080端口
http://127.0.0.1:8080/
网页中出现下面的文字，就启动成功了

静态服务器
在路径/usr/local/var/www下放入文件mytest.html内容如下：
<h1>hello nginx! 2018-07-10</h1>
通过链接访问测试： http://127.0.0.1:8080/mytest.html
通用配置user nobody;
worker_processes 1;
events {
worker_connections 1024;
}
http { include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
client_max_body_size 20M; include conf.d/*.conf;}
注意到include conf.d/*.conf; 这样就可以将conf.d这个文件夹中的所有配置文件加载进来，实现单独配置，互不影响。
