Laravel from it version 5 and above has make this process very simple with the help of the artisan command. to listen or start you queue work in local develpment it's nothing that running the following commands:
php artisan queue:table
this first command is necessary to auto generate the queue migration file preset by laravel, after that you have to migrate that table with this traditional artisan command:
php artisan migrate
with all these set you only have one thing to do which is to set you queue driver in your
.env file as follow
QUEUE_DRIVER=database to tell Laravel that you queue driver will be using you database.
Then, if you are able to create an store you task in your queue table you can run the following command to listen and fire those task from your queue.
php artisan queue:work --queue=high,default
Even though these processes is very simple to do on local develpment, it some how tidious to implement when you want to deploy your application. and it defer from server hosting and platform. In this article we will see how to settup the supervisor on a VPS linux server.
Supervisor can be installed with
pip install: by running the this command:
pip install supervisor
Depending on the permissions of your system’s Python, you might need to be the root user to install Supervisor successfully using
You can also install supervisor in a virtualenv via
Supervisor configuration files are typically stored in the
/etc/supervisor/conf.d directory. Within this directory, you may create any number of configuration files that instruct supervisor how your processes should be monitored. For example, let's create a
laravel-worker.conf file that starts and monitors a
Once the installation is complete, we have to generate our configuration file. Create a folder named
/etc to do that run the following command:
sudo mkdir /etc/supervisor
And then execute the following. To notice that the echo_supervisor_conf was provided by supervisor.
echo_supervisord_conf > /etc/supervisor/supervisord.conf
now you can go at the [program] session of the file and edit it with your information as needed inspiring from the code bellow.
[program:laravel-worker] process_name=%(program_name)s_%(process_num)02d command=php /path/to/your-laravel-app/artisan queue:work sqs --sleep=3 --tries=3 autostart=true autorestart=true user=forge numprocs=8 redirect_stderr=true stdout_logfile=/home/forge/app.com/worker.log
In this example, the
numprocs directive will instruct Supervisor to run 8
queue:work processes and monitor all of them, automatically restarting them if they fail. Of course, you should change the
queue:work sqs portion of the
command directive to reflect your desired queue connection.
Once the configuration file has been created, you may update the Supervisor configuration and start the processes using the following commands:
sudo supervisorctl reread sudo supervisorctl update sudo supervisorctl start laravel-worker:*
This is just a simple helper to setting up your worker on production and there still a lot to learn about supervison. you can visit their supervisor-official-website for more information.
