Install PHP 7 Xdebug in Arch Linux

"Normally", these instructions should be also valid (in similar way) for other Linux distros.

1.- Install Xdebug using pacman:

sudo pacman -Sy xdebug

This is a simple way of importing MySQL database in Docker.

In you Dockerfile you must have a shared folder. Shared folder is a directory in your host machine that is mounted to Docker instance.
Put the exported sql file in the shared folder.
Login to your Docker instance via docker exec -it DOCKER_CONTAINER_ID bin/bash.
Login to MySQL via mysql -u USERNAME -p.

Install Supervisor with sudo apt-get install supervisor in Unix or brew install supervisor in Mac OSX. Ensure it's started with sudo service supervisor restart in Unix or brew services start supervisor in Mac OSX.

In Unix in /etc/supervisord/conf.d/ create a .conf file. In this example, laravel_queue.conf (contents below). Give it execute permissions: chmod +x laravel_queue.conf.

In Mac OSX first run supervisord -c /usr/local/etc/supervisord.ini and in /usr/local/etc/supervisor.d/ create a .conf file. In this example, laravel_queue.conf (contents below). Give it execute permissions: chmod +x laravel_queue.conf.

This file points at /usr/local/bin/run_queue.sh, so create that file there. Give this execute permissions, too: chmod +x run_queue.sh.

Now update Supervisor with: sudo supervisorctl reread in Unix and with: brew services restart supervisor in MAc OSX . And start using those changes with: sudo supervisorctl update.

How to setup Let's Encrypt for Nginx on Ubuntu 18.04 (including IPv6, HTTP/2 and A+ SLL rating)

Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

Basic RESTful API with Symfony 3 + FOSRestBundle (JSON format only) + FOSUserBundle + FOSOauthServerBundle

The API we are creating in this gist will follow these rules :

The API only returns JSON responses
All API routes require authenticationu
Authentication is handled via OAuth2 with password Grant Type only (no need for Authorization pages and such).
API versioning is managed via a subdomain (e.g. v1.api.example.com)

The API will be written in PHP with the Symfony 3 framework. The following SF2 bundles are used :

	version: '3.7'

	services:
	elasticsearch:
	image: elasticsearch:7.9.2
	ports:
	- '9200:9200'
	environment:
	- discovery.type=single-node
	ulimits:

	// app/Console/Kernel.php

	<?php

	namespace App\Console;

	use Illuminate\Console\Scheduling\Schedule;
	use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

	class Kernel extends ConsoleKernel
