Replace supervisor with systemd unit

[linux019]

As almost linux distros have been shipped with powerful systemd daemon it's not neccessary to install supervisord it to run queus
A simple unit like that does all the job

[Unit]
Description=Laravel queue worker

[Service]
User=www-data
Group=www-data
Restart=on-failure
ExecStart=/usr/bin/php /laravel/artisan queue:work

[Install]
WantedBy=multi-user.target

you have to place it in /etc/systemd/system
systemctl daemon-reload
systemctl enable laravel-queue.service
systemctl start laravel-queue.service

In reality, there is nothing to replace because supervisor is just a suggestion; i.e. there's no real technical dependency on it. Of course I see that the docs talk only about it, as this is just the way the docs were written.

I suggest you rather make a nice documentation PR how one can use systemd with the workers (and also horizon) so we all can benefit from it.

IMO this is a complex topic, it would be nice if it would cover everything the current guide for supervisor covers (i.e. stdout/stderr log redirection, max restart tries, etc.)

How do you run multiple queue workers that way?

[linux019]

[Unit]
Description=Laravel queues

[Service]
User=www-user
Group=www-user
Type=simple
Restart=on-failure
RestartSec=30
Nice=10
WorkingDirectory=/www/laravel/
ExecStart=/usr/bin/php artisan queue:work --queue=default --sleep=30 --timeout=1800 --tries=1 --memory=256
StandardOutput=null
TimeoutStartSec=30
[Install]
RequiredBy=multi-user.target

This one works for me well but it's not indeed to Ctrl+C and Ctrl+V into projects.
To run multiple workers you have to list them in "queue" parameter, add more lines ExecStart or create mutiple service units

Agree with @mfn this is a DOC pr rather than an idea for Laravel

Using systemd for multiple workers quickly becomes weird. You cannot list them in the queue parameter as suggested, this just adds more queues to the responsibility of a single worker process. I don't think that a systemd unit with type=simple supports several ExecStart.

A quick look around makes me think we need some a parent unit and several child units, where the child units uses WantedBy=parent-unit.target and PartOf=parent-unit.target, so when you start/stop the parent the children will also be affected. You would also need a WantedBy=multi-user.target if you want to start them when booting. It seems it can be done, but it will require more configuration that suggested.

Supervisor's numprocs=3 makes this really easy.

Could this help? https://unix.stackexchange.com/a/288310

/etc/systemd/system/test@.service - the important bit is the @ symbol

Still, Supervisor's numprocs=3 looks better - but systemd is already there.
Also, systemd units/targets can be started from an unprivileged user.

If you're using Laravel with AWS Elasticbeanstalk, AWS EB doesn't provide supervisor out of the box and I ended up integrating systemd.
