[SOLVED] How to keep Laravel Queue system running on server

Issue

I recently setup a Laravel Queue system. The basics are a cronjob calls a command which adds jobs to a queue and calls a second command which sends an email.

The system works when I ssh into my server and run php artisan queue:listen, but if I close my terminal the listener shuts down and the jobs stack up and sit in queue until I ssh back in and run listen again.

What is the best way to keep my queue system running in the background without needing to keep my connection open via ssh?

I tried running php artisan queue:work --daemon, and it completed the jobs in the queue, but when I closed my terminal it closed the connection and the background process.

Solution

Running

nohup php artisan queue:work --daemon &

Will prevent the command exiting when you log out.

The trailing ampersand (&) causes process start in the background, so you can continue to use the shell and do not have to wait until the script is finished.

See nohup

nohup - run a command immune to hangups, with output to a non-tty

This will output information to a file entitled nohup.out in the directory where you run the command. If you have no interest in the output you can redirect stdout and stderr to /dev/null, or similarly you could output it into your normal laravel log. For example

nohup php artisan queue:work --daemon > /dev/null 2>&1 &

nohup php artisan queue:work --daemon > app/storage/logs/laravel.log &

But you should also use something like Supervisord to ensure that the service remains running and is restarted after crashes/failures.
