1、打开终端, 查看是否已经安装了Homebrew, 直接终端输入命令
    localhost:~ xxx$ man brew
    如果Mac已经安装了, 会显示一些命令的帮助信息. 此时输入Q退出即可

    5、查询要安装的软件nginx是否存在
    localhost:~ xxx$ brew search nginx
    6、安装nginx*
    localhost:~ xxx$ brew install nginx

    ==> 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

    查看nginx配置文件目录
    open /usr/local/etc/nginx/

    查看ginx被安装到的目录　
    open /usr/local/Cellar/nginx
    7、启动nginx*
    localhost:~ xxx$ sudo nginx
    测试是否成功
    打开浏览器访问：localhost:8080

    出现下图 表示成功

    8 关闭nginx*

    localhost:~ xxx$ sudo nginx -s stop
