make && make install

cp php.ini-development /usr/local/php/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp sapi/fpm/php-fpm /usr/local/bin

vi /usr/local/php/php.ini
打开php配置文件找到cgi.fix_pathinfo配置项，这一项默认被注释并且值为1，根据官方文档的说明，这里为了当文件不存在时，阻止Nginx将请求发送到后端的PHP-FPM模块，从而避免恶意脚本注入的攻击，所以此项应该去掉注释并设置为0

然后网上一些教程说让修改php-fpm.conf添加以上创建的用户和组，
find / -name php-fpm.conf
vim ....php-fpm.conf

默认情况下etc/php-fpm.d/下有一个名为www.conf.defalut的配置用户的文件，执行下面命令复制一个新文件并且打开：
cp www.conf.default www.conf
vi www.conf
默认user和group的设置为nobody，将其改为合适的。
