In this tutorial on CakePHP 3.x, I will be explainging you an overview on how the different concepts in cakePHP are implemented and what are the basic steps required to start the installation process of a CakePHP application on ubuntu operating system.

Quick Steps to Implement and Install CakePHP 3.x Application on Ubuntu

Minimum Requirements for installation:

1. You should have PHP 5.5.9 or higher
2. mbstring extension package
3. intl extension package
3. Web Server For example: Apache having mod_rewrite is recommended

Lets start with the installation process

Step 1.  Download and install the Composer by running the following command

curl -s https://getcomposer.org/installer | php

Step 2: Install intl and mbstring extension packages by running the following command

sudo apt-get install php5-intl
sudo apt-get install mcrypt php5-mcrypt
sudo apt-get install libapache2-mod-php5

Step 3: Edit php.ini file and add following lines

extension = mcrypt.so
extension = intl.so

by running following commands

sudo nano /etc/php5/apache2/php.ini
sudo service apache2 restart

Step 4: To get a new CakePHP application by running this command

sudo php composer.phar create-project --prefer-dist -s dev cakephp/app  Folder_Name

Step 5: Always make sure the directories logs, tmp and all its subdirectories in your CakePHP installation(cakephp folder) are writable.

Step 6: Go to phpmyadmin and create a database e.g:cakephp_3

Step 7: Open Config/app.php and replace the values in the Datasources.default array with database details like database, username and password.

  'Datasources' => [
            'default' => [
                'className' => 'Cake\Database\Connection',
                'driver' => 'Cake\Database\Driver\Mysql',
                'persistent' => false,
                'host' => 'localhost',
                'username' => 'root',
                'password' => '',
                'database' => 'cakephp_3',
                'encoding' => 'utf8',
                'timezone' => 'UTC',
                'cacheMetadata' => true,
                'quoteIdentifiers' => false,
            ],
    ]

Step 8: Now go into your Application folder(eg:cake_project$ bin/cake server) and run

bin/cake server

This will make our application available at http://localhost:8765/. This code will make running the server, and if you want to exit then press

CTRL + C
