Requirements: nginx reverse proxy to php-fpm processing, communication uses TCP protocol, how to use more efficient UDS for communication?
.NET/C# processes communicate between gRPC and Unix domain sockets

For single-server deployments or when the web server and PHP-FPM are on the same machine: Unix domain sockets are often preferred due to their performance and security benefits. Because UDS avoids the overhead of the TCP/IP protocol stack, it reduces data replication and context switching, making it more efficient. In real-world tests, using UDS can typically increase throughput by 10%~30% with lower latency.

First, modify the php-fpm configuration, for example:www.conffile, configured as follows:

If you have a php-fpm container running on docker,UDS may not take effectThe reason is because zz-docker.conf overwrites our configuration, and the modification is as follows:

Dockerfile：The hyperlink login is visible.

At the same time, when starting the container, the UDS is mapped and increased-v /data/phprun:/var/runParameter.



The first letter is s to indicate that this is a socket file (i.e. UDS)

nginx is modified as follows:

Reference:The hyperlink login is visible.
