4. 创建配置文件

cp php.ini-development /usr/local/php7/php.ini
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
// 方法1
cp -R sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
// 如果没有权限启动
cd /etc/init.d/php-fpm
chmod 755 php-fpm
//启动停止
/etc/init.d/php-fpm start|stop
// 方法2
cp php-7.2.1/sapi/fpm/php-fpm /usr/local/bin/
//启动停止
php-fpm | pkill php-fpm
