How can I determine the current config of php-fpm?

Question

I'd like to determine the current config that is 'loaded'. These would be all the values listed here: http://php.net/manual/en/install.fpm.configuration.php

These values are not returned by phpinfo().

Answer 1

If you have access to server, try, depending on php version

sudo php-fpm7.0 -tt sudo php-fpm7.x -tt sudo php-fpm7.4 -tt 

It test the current config file and show config params values (also default ones). The displayed values can differs from current running config if a modification happened and php-fpm hasn't been reloaded.

Only tested out on php-fpm 7.4

Note: Output from the command goes to standard error and that makes piping to something like grep or less inconvenient. To account for this:

php-fpm7.4 -tt 2>&1 | grep access 

Answer 2

There are two ways to check it out, as far as I know

1. use ps command to locate the fpm config file and read it

 root@c56686e9854c:/# ps aux | grep php-fpm  | grep master 

root 1 0.0 0.9 455112 37324 ? Ss 12:01 0:00 php-fpm: master process (/usr/local/etc/php-fpm.conf)

2. use php-fpm's own command

root@c56686e9854c:/# php-fpm -tt
