What should I do if php-fpm fails to start after installing PHP on centOS?

yum install epel-release -y yum update

wget http://am1.php.net/distributions/php-7.2.1.tar.gz tar xvf php-7.2.1.tar.gz

cd /php-7.2.1

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel

make make install

cp php.ini-development /usr/local/php7/etc/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

chmod +x /etc/init.d/php-fpm
