brew命令

brew info nginx： 可以查看我用brew install 安装nginx后的信息

nginx: stable 1.15.7 (bottled), HEAD
HTTP(S) server and reverse proxy, and IMAP/POP3 proxy server
https://nginx.org/
Not installed
From: https://mirrors.ustc.edu.cn/homebrew-core.git/Formula/nginx.rb
==> Dependencies
Required: openssl ✔, pcre ✘
Optional: passenger ✘
==> Options
--with-passenger
    Compile with support for Phusion Passenger module
--HEAD
    Install HEAD version
==> Caveats
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
