How To Install CodeIgniter on Ubuntu 18.04 LTS

Install CodeIgniter on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install CodeIgniter on Ubuntu 18.04 LTS. For those of you who didn’t know, CodeIgniter is a powerful PHP framework with a very small footprint, built for PHP coders who need a simple and elegant toolkit to create full-featured web applications.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of CodeIgniter on a Ubuntu 18.04 LTS (Bionic Beaver) server.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install CodeIgniter on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB, and PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also, install all required PHP modules:

apt-get install php7.1-cli php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Installing CodeIgniter on Ubuntu 18.04 LTS.

First, download the latest stable release of Codeigniter:

wget https://github.com/bcit-ci/CodeIgniter/archive/3.1.8.zip
unzip 3.1.8.zip
cp -r CodeIgniter-3.1.8 /var/www/html/codeigniter

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/codeigniter
chmod -R 777 /var/www/html/codeigniter/

Step 4. Configuring Apache web server for CodeIgniter.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘codeigniter.conf’ on your virtual server:

touch /etc/apache2/sites-available/codeigniter.conf
ln -s /etc/apache2/sites-available/codeigniter.conf /etc/apache2/sites-enabled/codeigniter.conf
nano /etc/apache2/sites-available/codeigniter.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin admin@yourdomain.com
DocumentRoot /var/www/html/codeigniter
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory /var/www/html/codeigniter/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
</VirtualHost>

Now, we can restart the Apache webserver so that the changes take place:

sudo a2ensite codeigniter.conf
sudo a2enmod rewrite
sudo systemctl restart apache2.service

Step 5. Accessing CodeIgniter.

CodeIgniter will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com or http://your-server-ip and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.

Congratulations! You have successfully installed CodeIgniter. Thanks for using this tutorial for installing CodeIgniter on your Ubuntu 18.04 LTS (Bionic Beaver) system. For additional help or useful information, we recommend you to check the official CodeIgniter website.
