nginx本身不能处理PHP，当接收到php请求后，则发给php解释器处理，并把结果返回给客户端。

nginx一般是把请求发fastcgi管理进程处理，fascgi管理进程选择cgi子进程处理结果并返回被nginx

本文介绍如何使用nginx支持PHP

安装php-fpm

下载源码包

http://www.php.net/downloads.php

http://at1.php.net/distributions/php-5.6.29.tar.gz

[root@bogon ~]# tar zxvf php-5.6.29.tar.gz 

[root@bogon ~]# cd php-5.6.29

安装前 先安装phpa安装所依赖的库文件

[root@bogon php-5.6.29]# yum -y install gcc automake autoconf libtool make 

[root@bogon php-5.6.29]# yum -y install gcc gcc-c++ glibc  

[root@bogon php-5.6.29]# yum -y install libmcrypt-devel mhash-devel libxslt-devel

[root@bogon php-5.6.29]# yum -y install bzip2 bzip2-devel curl-devel openssl openssl-deve readline-devel

安装中报错configure: error: mcrypt.h not found. Please reinstall libmcrypt.

下载个源码包安装。下载地址：

[root@bogon php-5.6.29]# ./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-inline-optimization --disable-debug --disable-rpath --enable-shared --enable-opcache --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-gettext --enable-mbstring --with-iconv --with-mcrypt --with-mhash --with-openssl --enable-bcmath --enable-soap --with-libxml-dir --enable-pcntl --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-sockets --with-curl --with-zlib --enable-zip --with-bz2 --with-readline --without-sqlite3 --without-pdo-sqlite --with-pear

[root@bogon php-5.6.29]# make

[root@bogon php-5.6.29]# nake install

添加 PHP 命令到环境变量

vim /etc/profile

在末尾加入

PATH=$PATH:/usr/local/php/bin

export PATH

要使改动立即生效执行

source /etc/profile

 配置php-fpm

cd /usr/local/php/etc

cp php-fpm.conf.default php-fpm.conf

启动php-fpm

/usr/local/php/sbin/php-fpm

nginx安装步骤在此不赘述，直接配置nginx. conf 文件

location / {

root /data/123;

index index.html index.htm index.php;

}

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /data/123 $fastcgi_script_name;

include fastcgi_params;

}

nginx+php
