Was soll ich tun, wenn php-fpm nach der Installation von PHP auf centOS nicht startet?

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 /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
