Usually /var/run and /run are symlinks one of the other so that makes /var/rum/php7.0-fpm.sock and /run/php7.0-fpm.sock the same unix domain socket

Hello, So, the need to make sense of this is not an issue: I will be using the mod_proxy_fcgi to use php-fpm. I am just curious. While trying various configurations to get php-fpm to work, I found the following conundrum: the following configuration should NOT work but it does... Here is the apache configuration snippet derived from this site <https://www.howtoforge.com/tutorial/apache-with-php-fpm-on-ubuntu-16-04/> dated last August. <Directory /usr/lib/cgi-bin> Require all granted </Directory> <IfModule mod_fastcgi.c> AddHandler php7-fcgi .php Action php7-fcgi /php7-fcgi virtual Alias /php7-fcgi /usr/lib/cgi-bin/php7-fcgi FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi -socket /var/run/php/php7.0-fpm.sock -pass-header Authorization </IfModule> Here is the php-fpm www pool socket definition as configured out-of-the-box: listen = /run/php/php7.0-fpm.sock My test php script calls phpinfo() only. It works. It’s not clear how it works. Apache opens /var/run/php/php7.0-fpm.sock php-fpm opens /run/php/php7.0-fpm.sock removal of either file causes php not to work. When I point apache to the socket file php-fpm opens, it does not work. HOW? How does apache manage to connect to php-fpm when the defined socket paths do not make sense? As far as I know, the unix socket file is simply opened and read/written to: there’s no way to tell linux “connect both files to each other” from within a program... Thanks for your time!
