Setup CodeIgniter

This example will use wget to install CodeIgniter from within the Devilbox PHP container.

After completing the below listed steps, you will have a working CodeIgniter setup ready to be served via http and https.

local

Overview

The following configuration will be used:

Project name	VirtualHost directory	Database	TLD_SUFFIX	Project URL
my-ci	/shared/httpd/my-ci	my_ci	loc	http://my-ci.loc https://my-ci.loc

Note

* Inside the Devilbox PHP container, projects are always in /shared/httpd/. * On your host operating system, projects are by default in ./data/www/ inside the Devilbox git directory. This path can be changed via env_httpd_datadir.

Walk through

It will be ready in eight simple steps:

1. Enter the PHP container
2. Create a new VirtualHost directory
3. Download CodeIgniter
4. Symlink webroot directory
5. Add MySQL database
6. Configure datbase connection
7. Setup DNS record
8. Visit http://my-ci.loc in your browser

1. Enter the PHP container

All work will be done inside the PHP container as it provides you with all required command line tools.

Navigate to the Devilbox git directory and execute shell.sh (or shell.bat on Windows) to enter the running PHP container.

host> ./shell.sh

* enter_the_php_container * work_inside_the_php_container * available_tools

2. Create new vhost directory

The vhost directory defines the name under which your project will be available. ( <vhost dir>.TLD_SUFFIX will be the final URL ).

devilbox@php-7.0.20 in /shared/httpd $ mkdir my-ci

env_tld_suffix

3. Download CodeIgniter

Navigate into your newly created vhost directory and install CodeIgniter.

devilbox@php-7.0.20 in /shared/httpd $ cd my-ci
devilbox@php-7.0.20 in /shared/httpd/my-ci $ wget https://github.com/bcit-ci/CodeIgniter/archive/3.1.8.tar.gz
devilbox@php-7.0.20 in /shared/httpd/my-ci $ tar xfvz 3.1.8.tar.gz

How does the directory structure look after installation:

devilbox@php-7.0.20 in /shared/httpd/my-ci $ tree -L 1
.
├── 3.1.8.tar.gz
└── CodeIgniter-3.1.8

1 directory, 1 file

4. Symlink webroot

Symlinking the actual webroot directory to htdocs is important. The web server expects every project's document root to be in <vhost dir>/htdocs/. This is the path where it will serve the files. This is also the path where your frameworks entrypoint (usually index.php) should be found.

Some frameworks however provide its actual content in nested directories of unknown levels. This would be impossible to figure out by the web server, so you manually have to symlink it back to its expected path.

devilbox@php-7.0.20 in /shared/httpd/my-ci $ ln -s CodeIgniter-3.1.8/ htdocs

How does the directory structure look after symlinking:

devilbox@php-7.0.20 in /shared/httpd/my-ci $ tree -L 1
.
├── 3.1.8.tar.gz
├── CodeIgniter-3.1.8
└── htdocs -> CodeIgniter-3.1.8

2 directories, 1 file

As you can see from the above directory structure, htdocs is available in its expected path and points to the frameworks entrypoint.

Important

When using Docker Toolbox, you need to explicitly allow the usage of symlinks. See below for instructions:

• Docker Toolbox and howto_docker_toolbox_and_the_devilbox_windows_symlinks

5. Add MySQL Database

devilbox@php-7.0.20 in /shared/httpd/my-ci $ mysql -u root -h 127.0.0.1 -p -e 'CREATE DATABASE my_ci;'

6. Configure database connection

devilbox@php-7.0.20 in /shared/httpd/my-ci $ vi htdocs/application/config/database.php

<?php
$db['default'] = array(
        'dsn'   => '',
        'hostname' => '127.0.0.1',
        'username' => 'root',
        'password' => '',
        'database' => 'my_ci',
        'dbdriver' => 'mysqli',
        'dbprefix' => '',
        'pconnect' => FALSE,
        'db_debug' => (ENVIRONMENT !== 'production'),
        'cache_on' => FALSE,
        'cachedir' => '',
        'char_set' => 'utf8',
        'dbcollat' => 'utf8_general_ci',
        'swap_pre' => '',
        'encrypt' => FALSE,
        'compress' => FALSE,
        'stricton' => FALSE,
        'failover' => array(),
        'save_queries' => TRUE
);

7. DNS record

If you have Auto DNS configured already, you can skip this section, because DNS entries will be available automatically by the bundled DNS server.

If you don't have Auto DNS configured, you will need to add the following line to your host operating systems /etc/hosts file (or C:\Windows\System32\drivers\etc on Windows):

127.0.0.1 my-ci.loc

• howto_add_project_hosts_entry_on_mac
• howto_add_project_hosts_entry_on_win
• setup_auto_dns

8. Open your browser

All set now, you can visit http://my-ci.loc or https://my-ci.loc in your browser.

setup_valid_https
