FastCGI原理和CGI一样不过区别是把动态语言和HTTP服务器分离出来
C/S架构：客户端服务端
B/S ： 浏览器服务器
特点：
1、    FastCGI是HTTP服务器和动态脚本语言间通信的接口或者工具
2、    FastCGI优点是把动态语言解析和HTTP服务器分离开来
3、    Nginx、Apache、lighttpd以及多数动态语言都支持FastCGI
4、    FastCGI接口方法采用C/S结构，分为客户端（HTTP服务器）和服务器（动态语言解析服务器）
5、    PHP动态语言服务端可以启动多个FastCGI的守护进程
6、    http服务器通过（Nginx fastcgi_pass）FastCGI客户端和动态语言FastCGI服务端通信(如：php-fpm)

[root@A tools]# yum install mhash-devel -y                →下载
[root@A tools]# rpm -qa mhash mhash-devel            →检查
mhash-0.9.9.9-3.el6.x86_64
mhash-devel-0.9.9.9-3.el6.x86_64

[root@A tools]# yum install mcrypt mcrypt-devel -y   →下载mcrypt
[root@A tools]# rpm -qa  mcrypt                    →检查是否安装mcrypt
mcrypt-2.6.8-10.el6.x86_64

1、yum install libxslt-devel -y yum install openssl-devel -y
2、tar xf php-5.5.32.tar.gz
3、php参数

上面的错了就用这个

1、配置php解析文件
[root@A php-5.3.27]# ls -l php.ini-*
-rw-r--r—. 1 101 101 69606 7月  11 2013 php.ini-development    →生产环境
-rw-r—r—. 1 101 101 69627 7月  11 2013 php.ini-production     →开发环境
区别：生产环境把错误关闭，开发环境把错误打开

做php解析
首先修改下面的配置文件
[root@A php-5.3.27]# cp php.ini-production /application/php/lib/php.ini   --》把生产环境配置文件修改

2、配置php配置文件（fastcgi模式）配置文件php-fpm.conf
[root@A ~]# cd /application/php/etc/            ---》配置文件目录
[root@A etc]# ls
pear.conf  php-fpm.conf.default                
[root@A etc]# cp php-fpm.conf.default php-fpm.conf        --》要把这个改名才可以用

3、之后配置php-fpm.conf

　4、mkdir /app/logs

5、启动php
[root@A /]# /application/php/sbin/php-fpm  ---》如果下面什么也不出现就是启动成功了
6、查看端口
ss -lntup|grep 9000
