Running under systemd You can setup the daemon as a simple systemd service like this: [Unit] Description=ttrss_backend After=network.target mysql.service postgresql.service [Service] User=www-data ExecStart=/path/to/tt-rss/update_daemon2.php [Install] WantedBy=multi-user.target Use journalctl -u ttrss_backend to look through daemon console output.

Look for .lock or .stamp files that do not have the owner/group “www-data” (the webserver account).

Upgrading with Git Update base tt-rss code Change to tt-rss directory on your server and run git pull origin master.
