Installing Phalcon PHP in Ubuntu 18.04

requirements

  • database connectivity will require the php_pdo extension which can be found in the php7.2-common package

  • MySQL/ MariaDB or Aurora databases will need php_mysqlnd extension , while PostgreSQL will need php_pgsql extension. Both extensions are in the php7.2-pdo* packages

Hardware requirements

An AWS VM with 512 RAM and 1vCPU will be enough for simple sites such as blogs.

software prerequisites

We assume that we want to use PHP 7+ (e.g. 7.2)

Step 1 will be to install the following prerequisite programs:

  • curl
  • gettext
  • gd2 (php-gd)
  • libpcre3-dev
  • json (php-json)
  • mbstring (php-mbstring)
  • pdo_* (php7.2-pdo*)
  • fileinfo (php7.2-common)
  • openssl

Note that depending on what you want to do, pdo_* , openssl and mbstring may be optional.

Installation proper

  1. Get a stable release script: 
 curl - https://packagecloud.io/install/repositories/phalcon/stable/script.deb.sh | sudo bash
  1. Install Phalcon
sudo apt-get update &&
sudo apt-get install php7.2-phalcon
  1. Install Phalcon Developer Tools for Linux
sudo apt install -y git
cd
git clone git://github.com/phalcon/phalcon-devtools.git
  1. Enter the cloned directory and run
cd phalcon-devtools/
. ./phalcon.sh
  1. Create a symlink to the phalcon script
sudo ln -s ~/phalcon-devtools/phalcon.php /usr/bin/phalcon
sudo chmod ugo+x /usr/bin/phalcon
  1. Check for installation success using phalcon commands
$ phalcon commands

Generating a Project Skeleton

$ cd
$ mkdir projects
$ cd projects
$ phalcon create-project store

Using the Built-in Webserver (for Development)

$(which php) -S localhost:8000 -t public .htrouter.php
  • $(which php) - will insert the absolute path to your PHP binary
  • -S localhost:8000 - invokes server mode with the provided host:port
  • -t public - defines the servers root directory, necessary for php to route requests to assets like JS, CSS, and images in your public directory
  • .htrouter.php - the entry point that will be evaluated for each request

Go to http://localhost:8000/ to check if everything is working.
