From Nextcloud background jobs.
In order to get systemd to run the cron job every 5 minutes you need to do the following. Here is my configuration for my nextcloud instance (public)
/etc/systemd/system/nextcloud_autotraining.service
[Unit]
Description=Nextcloud cron.php job
[Service]
User=www-data
ExecStart=/usr/bin/php -f /var/www/autotraining.duckdns.org/cron.php
root@raspberrypi:~# cat /etc/systemd/system/nextcloudcron_autotraining.timer
[Unit]
Description=Run Nextcloud cron.php every 5 minutes
[Timer]
OnBootSec=5min
OnUnitActiveSec=5min
Unit=nextcloudcron_autotraining.service
[Install]
WantedBy=timers.target
root@raspberrypi:~# cat /etc/systemd/system/nextcloudcron_autotraining.service
[Unit]
Description=Nextcloud cron.php job
[Service]
User=www-data
ExecStart=/usr/bin/php -f /var/www/autotraining.duckdns.org/cron.php
Now the nextcloud_autotraining.timer
[Unit] Description=Nextcloud cron.php job [Service] User=www-data ExecStart=/usr/bin/php -f /var/www/autotraining.duckdns.org/cron.php root@raspberrypi:~# cat /etc/systemd/system/nextcloudcron_autotraining.timer [Unit] Description=Run Nextcloud cron.php every 5 minutes [Timer] OnBootSec=5min OnUnitActiveSec=5min Unit=nextcloudcron_autotraining.service [Install] WantedBy=timers.target
This now needs to be activated by:
systemctl enable --now nextcloudcron_autotraining.timer
Now as long as your filenames are correct, it should all start and run :)
