How to Install CodeIgniter on Amazon EC2: A Guide
As a data scientist or software engineer, there may come a time when you need to install CodeIgniter on Amazon EC2. This PHP framework is renowned for its speed, flexibility, and security, making it a preferred choice for many web developers. This article will guide you through the process of installing CodeIgniter on an Amazon EC2 instance, step by step.
What is Amazon EC2?
Amazon EC2 (Elastic Compute Cloud) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale computing easier, offering complete control of your computing resources and letting you run on Amazon’s proven computing environment.
What is CodeIgniter?
CodeIgniter is a powerful PHP framework designed to help developers write clean and efficient code. It offers a rich set of libraries for common tasks, a simple interface, and logical structure to access these libraries.
Prerequisites
Before we start, ensure that you have the following:
- An Amazon EC2 instance running
- SSH access to the EC2 instance
- Basic knowledge of Linux commands
Step 1: Update Your System
First, log into your Amazon EC2 instance. Once you’re in, update the system to the latest stable version. Use the following commands:
sudo apt-get update
sudo apt-get upgrade
Step 2: Install Apache
Install Apache web server using the following command:
sudo apt-get install apache2
To check if Apache is installed, enter your Amazon EC2 Public DNS URL into your web browser. You should see the Apache2 Ubuntu Default Page.
Step 3: Install PHP
Next, install PHP and necessary modules:
sudo apt-get install php libapache2-mod-php php-mcrypt php-mysql
To verify the installation, create a test PHP file in the Apache document root:
sudo nano /var/www/html/info.php
Add this line to the file:
<?php phpinfo(); ?>
Save and close the file. Now, if you access http://<your EC2 instance public DNS>/info.php in your browser, you’ll see the PHP info page.
Step 4: Install CodeIgniter
Download the latest version of CodeIgniter from the official website using wget:
cd /var/www/html/
sudo wget https://github.com/bcit-ci/CodeIgniter/archive/3.1.11.tar.gz
Extract the CodeIgniter files and move them to the Apache document root:
sudo tar xvf 3.1.11.tar.gz
sudo mv CodeIgniter-3.1.11/* /var/www/html/
Step 5: Configuring CodeIgniter
Open the database.php file found in the application/config/ directory:
sudo nano /var/www/html/application/config/database.php
Modify the hostname, username, password, and database to match your settings.
Step 6: Test CodeIgniter
To verify if CodeIgniter is correctly installed, access http://<your EC2 instance public DNS>/index.php in your browser. You should see the CodeIgniter welcome page.
Conclusion
That’s it! You’ve successfully installed CodeIgniter on an Amazon EC2 instance. Now, you can start developing your web applications on a secure, scalable environment. If you have any questions or run into any issues, feel free to leave a comment.
Remember to keep your systems updated and monitor your applications to ensure they are running optimally. Happy coding!
