编译安装 php5.6

下载php56

http://cn2.php.net

解压：

tar -zxvf php-5.6.xx.tar.gz

进入php56目录，configure，注意下自己安装目录

./configure  --enable-fpm  --with-fpm-user=www  --with-fpm-group=www  --prefix=/usr/local/php-56  --with-config-file-path=/etc/php/56  --sysconfdir=/etc/php/56  --with-config-file-scan-dir=/etc/php/56/conf.d  --enable-mbstring  --enable-pcntl  --with-mysql=mysqlnd  --with-zlib  --with-png-dir  --with-jpeg-dir  --with-freetype-dir  --with-gd  --enable-gd-native-ttf  --with-curl=shared  --with-mysqli=mysqlnd  --enable-soap=shared  --enable-sockets=shared  --enable-mysqlnd  --with-pdo-mysql=mysqlnd  --with-gettext=shared  --with-mcrypt=shared  --with-openssl=shared

将php56软链到/usr/sbin下

sudo ln -s /usr/local/php-56/bin/php php56

php扩展的目录，请看configure --prefix参数，如上配置/usr/local/php-56/lib/php/extensions/，扩展的配置文件请看configure   --with-config-file-path参数，如上/etc/php/56，在/etc/php/56目录下建立conf.d目录，扩展配置的配置文件放到conf.d目录下，如mcrypt.so扩展配置文件mcrypt.ini

extension=mcrypt.so

添加php56-fpm service，在/etc/init.d目录下新建php56-fpm文件，文件内容

#! /bin/sh
