Here is quick guide how to run ProdigyView - PHP MicroServices Examples on Plain Debian 9 Linux

Setup

Tested OS:

lsb_release -ds
   Debian GNU/Linux 9.9 (stretch)

Problem: We need at least PHP7.1 - using guide from https://blog.venca-x.cz/debian-9-stretch-instalace-php-7-1/

sudo bash
apt-get install apt-transport-https lsb-release ca-certificates
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > \
      /etc/apt/sources.list.d/php.list
apt-get update

Install common requirements:

sudo apt-get install php7.1-cli php7.1-common php7.1-xml \
                     php7.1-mbstring composer git

Optional: Install tmux to have multiple terminal windows available via ssh:

sudo apt-get install tmux

Now we can setup examples (as any unprivileged user):

mkdir ~/projects
cd ~/projects
git clone https://github.com/ProdigyView-Toolkit/Microservices-Examples-PHP.git
cd Microservices-Examples-PHP

Running examples

Running e-mail example:

Install any Mail Transport Agent (MTA) - the example require command /usr/sbin/sendmail in the system. Try for example:

sudo apt-get install exim4

We may partially follow https://github.com/ProdigyView-Toolkit/Microservices-Examples-PHP#how-to-run

cd ~/projects/Microservices-Examples-PHP/email
# NOTE: 'composer install' did not work well in my example (missing classes etc...)
composer update
# ensure that there are no errors (warning are mostly OK :-)

Now we can prepare tmux:

  • run tmux command
  • press Ctrl-b followed by " (without Ctrl !) to open new pane.

Now press Ctrl-b followed by ; to swith to upper pane. And enter command:

php7.1 server.php
# there should be no message

Now press Ctrl-b followed by ; to switch back to lower pane. And enter command:

php7.1 client.php
   Message Sent

In server pane you should see new message Processing...

NOTE: The e-mail will be not actually delivered, however you can look at Exim4 log:

sudo tail /var/log/exim4/mainlog | grep example.com
   2019-06-08 08:43:51 1hZWx5-0003xE-Rq <= [email protected] U=ansible P=local S=921 id=afhIrPchdPmIHhFiNoVTpTJJrAKu63g3bKCUApXk@debian-9
   2019-06-08 08:43:52 1hZWx5-0003xE-Rq ** [email protected] R=nonlocal: Mailing to remote domains not supported
   2019-06-08 08:43:52 1hZWx6-0003xG-8L ** [email protected] R=nonlocal: Mailing to remote domains not supported

To end server do this:

  • press Ctrl-b followed by ; to switch back to upper pane
  • press Ctrl-c to terminate server

Now you can go to next example...

NOTE: To completely exit tmux you can use Ctrl-b followed by x (and answer yes to question Kill pane (y/n)?. And repeat it again to kill next pane. Then tmux will exit.

Running "Video Processing and RabbitMQ" example

We need to install additional dependencies:

sudo apt-get install rabbitmq-server wget ffmpeg php7.1-bcmath

And then basically follow https://github.com/ProdigyView-Toolkit/Microservices-Examples-PHP#video-processing-and-rabbitmq:

cd ~/projects/Microservices-Examples-PHP/video
# NOTE: I rather use update instead of install:
composer update

Ensure there is no error in composer update output (it often means that some required php extension is not installed).

Run server in one terminal/pane:

cd ../video # ensure that your NOT in email directory any longer!
php7.1 server.php

And run client in another terminal/pane:

cd ../video # ensure that your NOT in email directory any longer!
php7.1 client.php
  Sent Video To Server!'

On server pane you should see progress:

Done.

Restful Crud API

You need to install this additional package:

sudo apt-get install php7.1-curl

And then follow https://github.com/ProdigyView-Toolkit/Microservices-Examples-PHP#restful-crud-api (with one exception - I rather used update instead of install).

Also note that this time server is started using:

cd ../rest
php7.1 -S 127.0.0.1:8080
   PHP 7.1.30-1+0~20190531112602.19+stretch~1.gbpab9d28 Development Server started at Sat Jun  8 09:34:12 2019
   Listening on http://127.0.0.1:8080
   Document root is /home/ansible/projects/Microservices-Examples-PHP/rest
   Press Ctrl-C to quit.

And client (standard):

cd ../rest

More examples

Not yet tested (TODO).
