php – proxy: unix does not work with httpd in centos 7

I use httpd as a web server and php language with fpm but everything I get blank page
without errors

conf file:

SetHandler "proxy: unix: /var/run/php7.2-fpm.eslam.eslam.sock | fcgi: // localhost /"

php-fpm: listen = /var/run/php7.2-fpm.eslam.eslam.sock

How can I solve this problem ??
