@Izorkin there are many modules using phpfpm I suggest a checklist might be worth making.

I've been testing through bits and bobs and yeah, I can't seem to find any breakage. So I think we should pull it in and hope that people report errors if something breaks.

@Izorkin I'm having a few issues with this module now.

Also, I don't recall why the socket location was changed from /run/phpfpm/ to /run/phpfpm-${name}. This is a breaking change and I can't seem to remember the justification for it at the moment. Something to do with permissions?

To prevent the user "user1" View the contents of the folder / run / phpfpm-example-php73.
Example:

sudo ls -lah /run | grep phpfpm
drwxr-x---  2 user1   user1    60 июн 27 22:05 phpfpm-example-php72
drwxr-x---  2 user2   user2    60 июн 27 22:05 phpfpm-example-php73

sudo ls -lah /run/phpfpm-example-php72

drwxr-x---  2 user1   user1    60 июн 27 22:05 .
drwxr-xr-x 22 root    root    620 июн 28 13:28 ..
srw-------  1 user1   user1     0 июн 27 22:05 php72.sock.sock

sudo ls -lah /run/phpfpm-example-php73

drwxr-x---  2 user2   user2    60 июн 27 22:05 .
drwxr-xr-x 22 root    root    620 июн 28 13:28 ..
srw-------  1 user2   user2     0 июн 27 22:05 php73.sock.sock
