Question

I have a Symfony2 core, which is used for domain A and domain B. But, if I update the core, I need to update two times, because I don’t know how to configure only one core, with multiple domains with theirs configs/databases.

Suggestions?

Make a copy of the “web” directory into the “public_html” folder on each domain (assuming you are running Apache on Linux)

This “web” directory contains the front controllers of your site (app.php and app_dev.php), locate them and edit them on your favorite text editor. Locate this lines:

require_once __DIR__.'/../app/bootstrap.php.cache';
require_once __DIR__.'/../app/AppKernel.php';

and change the route to the actual relative path where your core is located. It could be something like this:

require_once __DIR__.'/../the_core_is_here/app/bootstrap.php.cache';
require_once __DIR__.'/../the_core_is_here/app/AppKernel.php';

This is flexible, and can be organized as you like, but make sure this two lines have the correct path

Keep in mind that all the assets (JS, CSS, images …) you include into your HTML are relative to the front controller location, so you will need to link them using the full url of the domain name where they reside or copy them also to the B domain or use assetic

At the end you will have something like:

/
.. home
.. .. DOMAINA
.. .. .. public_html
.. .. .. .. app.php
.. .. .. .. img
.. .. .. .. .. image.png
.. .. DOMAINB
.. .. .. public_html
.. .. .. .. app.php
.. .. .. .. img
.. .. .. .. .. image.png
.. .. the_core_is_here
.. .. .. app
.. .. .. src
.. .. .. bin
.. .. .. vendor

Now you should have 2 entry points for your application. You can even put different CSS and images on each to give them different aspect.
