CPU满负载，故停止测试（1G还是不够看，系统有损耗。）

煮酒品茶：非官方说法，nginx处理静态界面非常不错，终于被逮着一个500错误，处理高锋时比较占CPu，内存基本上就是系统所消，处理静态页面更多依靠的是流量来PD，所以静态页面可以放心的交给nginx处理。
下章测phpinfo，然后再测优化内核以及优化其它选项结果。

总图：
煮酒品茶;最开始用1G单核测，系统本身要占用资源，静态页面轻松的当掉是没有问题的，后增加四核四G内存测试，效果才慢慢出来，测试数据采集有所不精确请原谅，直至最后phpinfo.php页面5w***端当掉为止。此为采样数据。有所不当的地方请指教。
个人分析：1k-5w的连接cpu占用率为40左右单70左右，内存一直占用1G左右，连接的地页面的压缩优化至关重要。
安装参数：
Nginx依赖包：
Yum install -y gcc openssl-devel pcre-devel zlib-devel
Nginx安装：
Wget http://www.nginx.org/download/nginx-1.2.1.tar.gz
Tar zxvf nginx-1.2.1.tar.gz
Cd nginx-1.2.1
./configure --prefix=/usr/local/nignx
Make
Make install
Php依赖包：
Yum install -y gcc-c++ libxml2 libxml2-devel autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel
安装Php;
http://cn2.php.net/get/php-5.3.14.tar.gz/from/cn.php.net/mirror
cd php-5.3.14
./configure --prefix=/usr/local/php --enable-fpm
Make
Make install
cp /usr/local/php/etc/php-fpm.conf.default/usr/local/php/etc/php-fpm.conf
修改nginx.conf让其支持php：
保证有以下行
--------------------------------------------------------------
location ~ \.php$ {
root /data/www;
fastcgi_pass 127.0.0.1:9000;
fastcgi_indexindex.php;
fastcgi_paramSCRIPT_FILENAME/data/www$fastcgi_script_name;
include fastcgi_params;
}
启动nginx与php
/usr/local/nginx/sbin/nginx
/usr/local/php/sbin/php-fpm
