1、下载php安装包
http://cn2.php.net/get/php-5.5.36.tar.gz/from/this/mirror
默认情况下Nginx和PHP他俩之间是一点感觉没有的。Apache+PHP编译后生成的是模块文件，而Nginx+PHP需要PHP生成可执行文件才可以，所以要利用fastcgi技术来实现Nginx与PHP的整合，这个只要我们安装时启用 FastCGI即可。此次我们安装PHP不仅使用了FastCGI，而且还使用了PHP-FPM这么一个东东，PHP-FPM说白了是一个管理 FastCGI的一个管理器，它作为PHP的插件存在，在安装PHP时要想使用PHP-FPM就需要把PHP-FPM以补丁的形式安装到PHP中，而且 PHP要与PHP-FPM版本一致，这是必须的，切记！
2、安装
[root@localhost src]# <span>tar</span> -zxvf php-<span>5.5</span>.<span>36</span>.<span>tar</span><span>.gz [root@localhost src]# cd php</span>-<span>5.5</span>.<span>36</span><span> [root@localhost php</span>-<span>5.5</span>.<span>36</span>]# ./configure --prefix=/usr/local/php --with-config-<span>file</span>-path=/usr/local/php/etc --with-png-<span>dir</span>=/usr/local/libpng --with-jpeg-<span>dir</span>=/usr/local/jpeg --with-freetype-<span>dir</span>=/usr/local/freetype --with-zlib-<span>dir</span>=/usr/local/zlib --with-mcrypt=/usr/local/libmcrypt --with-libxml-<span>dir</span>=/usr/local/libxml2/ --with-iconv-<span>dir</span>=/usr/local/libiconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring=all --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-<span>zip</span> --enable-soap --without-pear --with-gettext --enable-session --with-curl --enable-ctype --enable-shared --with-<span>gd [root@localhost php</span>-<span>5.5</span>.<span>36</span>]<span>make</span><span> clean [root@localhost php</span>-<span>5.5</span>.<span>36</span>]<span>make</span><span> [root@localhost php</span>-<span>5.5</span>.<span>36</span>]<span>make</span> <span>install</span>
3、将源码中的php.ini-development复制到设置的 php.ini 的搜索路径下
[root@localhost php-<span>5.5</span>.<span>36</span>]# <span>cp</span> php.ini-development /usr/local/php/etc/php.ini
4、复制一份php-fpm配置文件，命名为php-fpm.conf（/usr/local/php/etc路径下）
[root@localhost etc]# <span>cp</span> php-fpm.conf.default php-fpm.conf
5、启动php-fpm
[root@localhost /]# /usr/local/php/sbin/php-<span>fpm [root@localhost </span>/]# <span>ps</span> aux | <span>grep</span> php-<span>fpm root </span><span>7790</span> <span>0.0</span> <span>0.2</span> <span>27300</span> <span>3048</span> ? Ss <span>22</span>:<span>23</span> <span>0</span>:<span>00</span> php-fpm: master process (/usr/local/php/etc/php-<span>fpm.conf) nobody </span><span>7791</span> <span>0.0</span> <span>0.4</span> <span>27300</span> <span>4380</span> ? S <span>22</span>:<span>23</span> <span>0</span>:<span>00</span> php-<span>fpm: pool www nobody </span><span>7792</span> <span>0.0</span> <span>0.2</span> <span>27300</span> <span>2524</span> ? S <span>22</span>:<span>23</span> <span>0</span>:<span>00</span> php-<span>fpm: pool www root </span><span>8124</span> <span>0.0</span> <span>0.0</span> <span>4420</span> <span>756</span> pts/<span>3</span> S+ <span>23</span>:<span>19</span> <span>0</span>:<span>00</span> <span>grep</span> php-fpm
附：
1、查找php配置文件路径
[root@localhost /]# /usr/local/php/bin/php --<span>ini Configuration File (php.ini) Path: </span>/usr/local/php/<span>etc Loaded Configuration File: </span>/usr/local/php/etc/<span>php.ini Scan </span><span>for</span> additional .ini files <span>in</span><span>: (none) Additional .ini files parsed: (none)</span>
2、关闭php-fpm
[root@localhost /]# <span>killall</span> php-fpm
3、php核心配置选项列表
http://php.net/manual/zh/configure.about.php
