Configuring the shared hosting environment

Configuring the shared hosting environment is crucial for proper CodeIgniter functionality on the server.

Here are the necessary configurations to be done:

1. Database Setup

  • Create a new MySQL database and note down the credentials.

  • Open CodeIgniter’s configuration file (config.php) and update the database information.

  • Specify the database hostname, username, password, and database name.

2. Setting up Base URL

  • In the same config.php file, find the `$config[‘base_url’]` line and update it.

  • Set the base URL according to your shared hosting setup, e.g., `` or ``.

3. Configuring .htaccess file

  • Create a new file called `.htaccess` in your CodeIgniter project’s root directory.

  • Open the file and add the following code:
RewriteEngine on

RewriteCond $1 !^(index\\.php|images|css|js|robots\\.txt|favicon\\.ico)

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php/$1 [L,QSA]
  • This code enables clean URLs and removes “index.php” from your URLs.

  • Ensure that mod_rewrite is enabled on your shared hosting server.

4. Additional Configurations

  • Adjust the session configurations in the `config.php` file, if required.

  • Specify the encryption key in the same file by setting `$config[‘encryption_key’]`.

  • Set the timezone using the `$config[‘timezone’]` variable to match your application’s needs.

5. Verify and Test

  • Upload your CodeIgniter app to the shared hosting server.

  • Access the application through the defined base URL in a web browser.

  • Verify that the database connection is established and working.

  • Test various features of your app to ensure proper functionality.

By following these necessary configurations, you can ensure that your CodeIgniter app works smoothly on a shared hosting plan.

Testing and troubleshooting

After deploying a CodeIgniter app on shared hosting, comprehensive testing and effective troubleshooting are critical for optimal performance:


  1. Ensure CodeIgniter app compatibility with the shared hosting environment.
