Some of you might have encountered this problem while setting up CodeIgnitor Project on your local machine or server. Let me explain the problem scenario.

The Problem

I had to make some changes to the existing codeigniter project. I downloaded the project, extracted the archive and moved the project to /var/www/html/ directory. Normally, any PHP project inside /var/www/html/ would work perfectly ( putting the database and other configurations aside) and this project was also supposed to work. But, I didn’t have any experience on CodeIgniter specifically. Anyway, I, then tried to launch a browser and entered a url I usually would: http://localhost/project_folder . But immediately it threw the 404 Not Found Error. I tried other routes as well but none worked.

I, then wondered if it work on xampp server and moved folder to /opt/lampp/htdocs/ . I stopped apache2 using sudo service apache2 stop and started xampp using sudo service xampp start . I don’t know why but it worked like a charm.

I could just stick to xampp and proceed to work but I didn’t get satisfied about that. I was curious about not working on apache2 and working on xampp. So, I started reading some dev articles and found a solution. Let’s talk about the solution.

404 Page Not Found: Codeigniter Project On Apache2 Ubuntu | Solution

The solution is to create a virtual host environment and run the project on that environment. Let me break down the solution into steps so that its easier to proceed.

Part 1

  1. Create A Virtual Host Environment
    Open your Terminal and go to this directory: /etc/apache2/sites-available. You might have to use sudo if do not have root privilege.
  2. Then create a new virtual host configuration, For now, we will name this configuration testproject. Use the following command:
    sudo vim testproject.conf
    Paste the following into the file:
<VirtualHost *:80>
    ServerName testproject.local
    DocumentRoot /var/www/html/testproject
    <Directory /var/www/html/testproject/>
        AllowOverride All
        Require all granted
        Allow from all

Now, save the file and exit to the terminial.

Part 2

  1. Edit the /etc/hosts (hosts file) using sudo vim /etc/hosts) and add the following line at the end of file: localhost testproject.local
    Now save the file and exit vim.
  2. Execute the following commands:
    sudo a2ensite testproject.conf
    sudo a2enmod rewrite
  3. Restart the apache2:
    sudo service apache2 reload or sudo service apache2 restart

We are all done now. Try to access your application using http://testproject.local . You should be able to see the CodeIgniter pages you were supposed to.
