nginx 是一个轻量级的高性能HTTP 以及反向代理服务器，今天在MAC 上安装成功。
我是通过brewhome 来安装的，很简单。brew install nginx 一路顺畅。。。
下面是安装信息。

==> Caveats
In the interest of allowing you to run `nginx` without `sudo`, the default
port is set to localhost:8080.
If you want to host pages on your local machine to the public, you should
change that to localhost:80, and run `sudo nginx`. You'll need to turn off
any other web servers running port 80, of course.
You can start nginx automatically on login running as your user with:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/Cellar/nginx/1.0.8/org.nginx.nginx.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/org.nginx.nginx.plist
Though note that if running as your user, the launch agent will fail if you
try to use a port below 1024 (such as http's default of 80.)
Warning: /usr/local/sbin is not in your PATH
You can amend this by altering your ~/.bashrc file
==> Summary
/usr/local/Cellar/nginx/1.0.8: 6 files, 616K, built in 19 seconds
hematoMacBook-Pro:~ hechangmin$
启动nginx ，sudo nginx ;访问localhost:8080 发现已出现nginx的欢迎页面了。
备注：ln -s /usr/local/sbin/nginx /usr/bin/nginx 做了个软连接。
常用的指令有：
nginx -V 查看版本，以及配置文件地址
nginx -v 查看版本
nginx -c filename 指定配置文件
nginx -h 帮助
nginx -s [reloadreopenstopquit]
brewhome 常用的指令：
brew search mysql : 搜索具体的程序包
brew install mysql : 安装具体的程序包
brew info mysql : 查看具体程序的信息
brew uninstall mysql : 卸载具体的应用（这里只是用mysql 作个例子）
我这里的配置文件地址：/usr/local/etc/nginx/nginx.conf
编辑内容，可以制定web 目录，以及PHP 、python 等
