Describe your issue

Hello, after each reboot, php and opendkim services do not work. I’m not sure if the two errors are related, but I think so.
The PHP error :

Jun 12 08:36:05 php-fpm8.3[1135]: [12-Jun-2025 08:36:05] ERROR: unable to bind listening socket for address '/var/run/php/php8.3-fpm-nextcloud.sock': No such file or directory (2)
Jun 12 08:36:05 php-fpm8.3[1135]: [12-Jun-2025 08:36:05] ERROR: FPM initialization failed
Jun 12 08:36:05 systemd[1]: php8.3-fpm.service: Main process exited, code=exited, status=78/CONFIG
Jun 12 08:36:05 systemd[1]: php8.3-fpm.service: Failed with result 'exit-code'.
Jun 12 08:36:05 systemd[1]: Failed to start php8.3-fpm.service - The PHP 8.3 FastCGI Process Manager.

The opendkim error :

Jun 10 13:13:14 opendkim[2686]: can't write pid to /run/opendkim/opendkim.pid: No such file or directory
Jun 10 13:13:14 systemd[1]: opendkim.service: Can't open PID file /run/opendkim/opendkim.pid (yet?) after start: No such file or directory

I can manually resolve the problems like this :
For PHP:

sudo mkdir -p /var/run/php/

For opendkim

sudo mkdir -p /run/opendkim/
sudo chown opendkim:opendkim /run/opendkim/
sudo chmod 755 /run/opendkim/

Then I can restart the two services in the web-admin. But after a reboot the problems are back.

During an update of PHP I saw the following error which might be related :

Detected unsafe path transition / (owned by debianadmin) → /run (owned by root) during canonicalization of /run.

“debianadmin” is the admin which was created during the installation of the underlying RaspberryPi OS. The YunoHost-Admin is a different one.

Hello @clay
A few questions to clarify the situation:

  • can you post the output of namei -l /var/run/php ? My guess is that it’s an ownership misconfiguration : / should be owned by root.
  • Is it the file /var/run/php/php8.3-fpm-nextcloud.sockor the directory /var/run/php that does not exist when you restart?
  • Can you post the content of /etc/php/8.3/fpm/pool.d/nextcloud.conf?

Hi @otm33
Thank you for your reply.

Here come my answers:

  • output of namei -l /var/run/php:
f: /var/run/php
drwxr-xr-x debianadmin debianadmin /
drwxr-xr-x root     root     var
lrwxrwxrwx root     root     run -> /run
drwxr-xr-x debianadmin debianadmin   /
drwxr-xr-x root     root       run
drwxr-xr-x root     root     php

  • The directory /var/run/php does not exist after a reboot. Neither does the directory /run/opendkim

  • the content of /etc/php/8.3/fpm/pool.d/nextcloud.conf:

[nextcloud]

user = nextcloud

chdir = /var/www/nextcloud

listen = /var/run/php/php8.3-fpm-nextcloud.sock

pm = ondemand

php_admin_value[upload_max_filesize] = 10G

php_admin_value[memory_limit] = 512M

Unless there is a specific need, you should restore ownership of / to root.

I think this happened by accident or automatically in the install-process. I can’t remember to have done this on purpose. Can you help me to safely change this to how it should be?

sudo chown root:root /

Problem solved, PHP and opendkim are running after a reboot. Thank you very much :slight_smile:
