Answer 1

you need to install supervisor also. Here is a tutorial on using beanstalkd with laravel:

Here are details on supervisor also:

http://supervisord.org/installing.html

I personally use a redis instance and run my queue with supervisor from there. I find its a bit more memory effective then beanstalkd personally but each to there own.

Supervisor will execute the queue:listen command from artisan and this will run a job, if you have multiple supervisor processes then you can run multiple in line items. depending on what you are doing i would almost look into python and multithereading also as i have used this for a few things i used to use a queue for and it has provided even better results.

example config file for supervisor:

[program:myqueue]
command=php artisan queue:listen --env=your_environment
directory=/path/to/laravel
stdout_logfile=/path/to/laravel/app/storage/logs/myqueue_supervisord.log
redirect_stderr=true
autostart=true
autorestart=true

Answer 2

You can also make use of Laravel's Task Scheduler i.e add the php artisan queue:listen command to the scheduler and sets its frequency to whatever you wants.

So that will make sure to call queue listen process automatically.

Hope it will make sense.
