可能会报错，提示需要安装zlib
查看yum是否安装，安装了还是提示错误的话就卸载了自己下载源码包编译安装，
如果zlib版本大于1.2的话可能会提示cmake版本过低，要求升级cmake

下载Cmake

wget https://cmake.org/files/v3.6/cmake-3.6.2.tar.gz

解压Cmake

将cmake移动到/usr/local/cmake3


make && make install

cp php.ini-development /usr/local/php/lib/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

vim /usr/local/php/lib/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

groupadd www-data
useradd -g www-data www-data

cp /usr/local/etc/php-fpm.d/www.conf.default /usr/local/etc/php-fpm.d/www.conf
vim /usr/local/etc/php-fpm.d/www.conf

默认user和group的设置为nobody，将其改为www-data

/usr/local/bin/php-fpm
