系统环境
centos 6.5 64位
nginx 1.6.2
mysql 5.6.23
php 5.6.6
依赖库
#为了省事，直接用yum来安装吧yum -y install libmcrypt-devel libxml2-devel curl-devel libjpeg-devel libpng-devel freetype-devel openssl-devel
创建php的日志目录mkdir -p /var/logs/php
设置编译参数./configure \--prefix=/usr/local/php \--with-config-file-path=/usr/local/etc/php \--with-mysql=/usr/local/mysql \--with-mysqli \--with-gd \--with-jpeg-dir \--with-png-dir \--with-freetype-dir \--with-curl \--enable-mbstring \--enable-sockets \--enable-pcntl \--enable-fpm \--with-fpm-user=nginx \--with-fpm-group=nginx \--with-mcrypt \--with-openssl \--with-pdo-mysql \--with-libxml-dir \--with-zlib \--with-pcre-dir
开始编译和安装make && make install
注：如果在编译过程中出现“virtual memory exhausted: cannot allocate memory”错误，则代表机器的内存太小，这时候可以试一下在编译参数中增加一个--diable-fileinfo，然后再重新编译安装配置php-fpm.conf
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/etc/php/php-fpm.confvi /usr/local/etc/php/php-fpm.conf
主要修改的地方有：
注：user和group要跟nginx的运行用户和组保持一致
配置php.ini
cp /usr/local/src/php-5.6.6/php.ini-development /usr/local/etc/php/php.inivi /usr/local/etc/php/php.ini
主要修改的地方有：
启动php-fpm
/usr/local/php/sbin/php-fpm -c /usr/local/etc/php/php.ini -y /usr/local/etc/php/php-fpm.conf
修改nginx.conf
重新启动nginx
/usr/local/sbin/nginx/nginx -s stop/usr/local/sbin/nginx/nginx -c /usr/local/etc/nginx/nginx.conf
以上就介绍了centos以源码方式安装php，包括了方面的内容，希望对php教程有兴趣的朋友有所帮助。
