Access denied when trying to use PHP unix sock

[patrick-vlt]

I'm trying to use the docker image hipages/php-fpm_exporter with docker-compose.

Which user runs the php-fpm exporter process? I keep seeing this error:

2023-08-25 21:56:59 time="2023-08-25T19:56:59Z" level=error msg="Pool[unix:///socket/fpm/unix.sock]: Access denied.\n"

The permissions for this sock are set to:

/fpm/unix.sock
srw-rw----    1 2002     web              0 Aug 25 19:28 /socket/fpm/unix.sock

I added the root user to the web group, but this didn't solve the problem.

Do you have rights set up on pool?

listen.mode = 0660 (default). I'm using 0666, since I need to flush opcache with library via pipeline and read it, but you should be ok with 0664

Having the same error, but on a Ubuntu 20 machine:

ll /run/php/php8.1-fpm.sock

srw-rw---- 1 www-data www-data 0 Oct 10 13:49 /run/php/php8.1-fpm.sock

sudo -u www-data ./php-fpm-exporter server --phpfpm.scrape-uri=unix:/run/php/php8.1-fpm.sock

INFO[0000] Starting server on :9253 with path /metrics

ERRO[0003] invalid character 'A' looking for beginning of value

but curl seems to respond with a valid result:

You're missing the path and therefore you're getting the access denied error and incomplete data.

It needs to be like this sudo -u www-data ./php-fpm-exporter server --phpfpm.scrape-uri='unix:/run/php/php8.1-fpm.sock;/status'
