# Upstream to abstract backend connection(s) for PHP. # Additional upstreams can be added to /etc/nginx/upstreams/*.conf and then you just # change `default php74` to whatever the new upstream is (could be php83 for example). upstream php83 { server unix:/run/php/php8.3-fpm.sock; } include /etc/nginx/upstreams/*.conf; map '' $upstream { default php83; }
