2.后台php需要开启900端口，也就是说要编译或者安装php，php的监听的地址修改为本机的ip地址，不能在是127.0.0.1了 否则nginx无法代理
3.nginx每个项目代码需要保存一份，php后台每个项目需要保存一份，代码目录要一致
静态的html用户请求 请求的是nginx上面的代码,动态的请求，请求的php服务器上面的代码
举一个简单的例子：bbs.sense.com 的代码在nginx上面/www/bbs 下保存一份，也得在php所在的服务器上面的/www/bbs 下面保存一份，静态的请求请求nginx服务器的代码，动态的请求请求php服务器的代码
上面基础架构存在问题：nginx单点 php单点 nginx单点可以用keepalived解决，但是php单点必须得增加后端服务器，如果增加后端的服务器，那么nginx应该怎么配置呢
第二种架构

这样做是轮询的方式从后端的php日志依然能够得出来,静态文件还是请求nginx动态文件还是请求php服务器，nginx和后端的php服务器组依然要部署和nginx相同路径的代码
