Usage

Before strating the easy Queue package, you need to do the following things:

Operating System

You need to have own Unix-like OS. Such as the Linux distro.For example, the Ubuntu, CentOS, Debian ans so on.

We strongly recommend you use the __Ubuntu__ for this tutorial because it woked well for our testing.

Install the required package

We have some packages for this repo.Here is the installing command for __Ubuntu 16.04 LTS__.

sudo apt-get update
sudo apt-get install beanstalkd
sudo apt-get install php7.0-cli

Getting Statred

This section is the tutorial. Here we go!

• Clone the repo.

git clone https://github.com/peter279k/Scheduler.git

• Download composer.phar and install the required packages.

curl -sS https://getcomposer.org/installer | php
cd path/to/this-project-root
php composer.phar install

• Create the job

The job is an action and asks for Queue to complete the action.

You can refer the `job.php` in `Examples` folder to understand how to create the jobs and push them to Queue.

You can refer the `SendMail.php` in `src` folder to understand how to extend this calss and create the job classes(such as `WeatherJob.php` and `MonitorJob.php`) and let them call in `job.php`.

• Start the Queue pool

Using the following command:

php path/to/Scheduler/src/worker.php

__The Queue pool will be expired after 2 minutes.__

__The timeout is not available for customizing value.__

If you have to make the queue non-stop, you can create a crontab job.

sudo contab -e
# add the following cron job in the cron file.
  * php path/to/Scheduler/src/worker.php >> /dev/null 2>&1

• Start the Job via PHP CLI in terminal

php job.php

If you run the `job.php`, you will look at the terminal window and notice that the output from the job handlers.
