之前流行过一段时间的Nginx+以fastCGI方式运行的PHP来搭建Web站点的方法。但是经过一段时间考量之后，大家经常发现会出现一些502的错误。其实一般是Nginx+fastCGIPHP的形式不太稳定造成。于是尝试了牛人推荐的一种是用Nginx做前端转发PHP请求给Apache的方法来进行服务器平台建设。这种方法有效的避免了Apache在应付大并发时候的些许不足和Nginx配合fastCGIPHP不太稳定的弊端。同时又在一定程度上利用了Nginx速度上的优势。说白了就是一些静态文件有Nginx来处理，PHP请求转发给后端Apache来处理。但是在效率上或者内存等资源占用上不如Nginx+fastCGI方式。
在PHP页面处理使用了suPHP,关于suPHP各位可以参照这里。suPHP其实现在被应用在很多空间租用商的服务器上。主要功能为了使用目录所有者的权限来执行特定位置的PHP页面，不是使用Apache默认Apache或者wwwdata或者nobody用户。
这样的好处主要有两点：
1.空间租用者（使用者）不需要在设置复杂权限了，在自己空间中PHP拥有完全权限。
2.空间租用者（使用者）存放网站文件的目录更安全，不需要开启Apache，wwwdate或者nobody之类权限对于自己站点，避免了777这样的高危权限。但是suPHP要求在编译安装PHP的时候必须编译为PHP-CGI形式才能是用，也就是不能使用平时我们所使用的CLI启动方式。
简单原理如下： CLI传统模式的图解：PHP是作为Apache一个模块存在，就像Apache的一个功能一样。
suPHP模式图解：suPHP作为Apache一个模块，在需要的时候以特定用户权限来启动PHP-CGI，从而实现以目录所有者权限执行PHP的功能。
最终原理图大致如下：由Nginx接受全部目的端口为80的Web请求，根据请求内容的不同进行过滤。静态文件例如：MP3、GIF、JPG、JS等文件 由Nginx处理，其他PHP Web请求转发到后端Apache服务器上。Apache服务器利用suPHP模块按照目录所有者权限运行PHP程序从而返回页面给客户端。稍加改动就可 以实现跨越多台计算机的群集功能。
我们操作系统平台为CentOS5.5，姑且称呼他为：Nginx+Apache+MySQL+suPHP

编辑Pure-FTP配置文件
#配置pure-ftpd,这里采用PureDB的验证方式. vim /usr/local/pureftpd/etc/pure-ftpd.conf #查找 PureDB /etc/pureftpd.pdb 取消前面的#号并设置成 PureDB /usr/local/pureftpd/etc/pureftpd.pdb #查找 PassivePortRange 取消前面的#号 # PS：如果想用系统用户验证 设置成以下值。 UnixAuthentication yes #MinUID 100 UnixAuthentication yes表示系统用户可以登录FTP。 MinUID 100表示用户的ID大于100才能登录，我们注释掉它，任何的用户ID都能登录了。
三、设置各服务开机自运行并启动服务
chkconfig --level 35 mysql on chkconfig --level 35 httpd on chkconfig --level 35 nginx on 启动和停止PureFTPd service pure-ftpd stop service pure-ftpd start service pure-ftpd status #以下内容为一行，请注意 echo '/usr/local/bin/memcached -d -m 64 -p 11211 -u nobody -l localhost' >>/etc/rc.d/rc.local service mysql start service httpd start service nginx start /usr/local/bin/memcached -d -m 64 -p 11211 -u nobody -l localhost

添加FTP帐户用于维护Web服务器
useradd -s /sbin/nologin whypc_info chmod a+x ~whypc_info pure-pw useradd whypc_info -u whypc_info -g \ whypc_info -d /home/whypc_info/ #该命令之后会提示你设置FTP用户密码 pure-pw mkdb #该命令每次添加用户之后都需要执行，不需要重启服务。 #启动Pure-FTP因为刚才还没有产生用户数据库，所以在这里启动。 /usr/local/pureftpd/sbin/pure-config.pl\ /usr/local/pureftpd/etc/pure-ftpd.conf --daemonize
更改Apache配置文件增加虚拟主机
cd /usr/local/apache/conf/vhosts
vim whypc.info.conf
#添加如下内容，IP地址和域名根据实际情况。

ServerName whypc.info
ServerAlias www.whypc.info

更改Nginx配置文件增加虚拟主机
cd /usr/local/nginx/conf/vhosts/
vim whypc.info.conf
#添加如下内容，IP地址和域名根据实际情况。
server {

五、创建测试文件
vim ~whypc_info/public_html/test.php
#写入如下内容
<?php
system("id");
?>
chown whypc_info:whypc_info ~whypc_info/public_html/test.php
通过浏览器查看是否为目录所有者权限（非nobody）。

新版PHP，已经不会出现502错误了，建议用新版PHP-FPM
@InBi 是的，已经在使用单Nginx配合PHP-FPM。^_^
