How to Install Ejabberd on Amazon EC2: A Guide for Data Scientists

As a data scientist or software engineer, you may find yourself in need of a robust, scalable, and extensible XMPP server. That’s where Ejabberd comes in. Written in Erlang, Ejabberd is a go-to choice for real-time applications where scalability and high availability are paramount. In this guide, we’ll walk you through how to install Ejabberd on an Amazon EC2 instance.

Prerequisites

Before we start, ensure you have:

  • An active AWS account.
  • Basic understanding of Linux commands.
  • Familiarity with Amazon EC2 instances.

Step 1 - Launch an Amazon EC2 instance

First, log in to your AWS Management Console and select EC2. Click on Launch Instance. For this tutorial, we’ll use the latest Ubuntu Server LTS as our instance type. After setting the instance details and security group, launch the instance and connect to it via SSH.

Step 2 - Update the Server

Once connected, update the server using the following commands:

sudo apt-get update -y
sudo apt-get upgrade -y

Step 3 - Install Erlang

Ejabberd requires Erlang to function. Install it as follows:

sudo apt-get install erlang -y

Verify the installation with erl -version.

Step 4 - Install Ejabberd

Now, download and install Ejabberd:

wget https://static.process-one.net/ejabberd/downloads/latest/ejabberd-latest.run
chmod +x ejabberd-latest.run
sudo ./ejabberd-latest.run

The installer will guide you through the setup process.

Step 5 - Configure Ejabberd

Next, navigate to the configuration file (/opt/ejabberd/conf/ejabberd.yml) and customize it to suit your needs, such as domain name, listening ports, and admin user.

sudo nano /opt/ejabberd/conf/ejabberd.yml

Remember to replace localhost with your domain name in hosts section.

Step 6 - Start Ejabberd

Start the Ejabberd service using the following command:

sudo /opt/ejabberd/bin/ejabberdctl start

Check the status with /opt/ejabberd/bin/ejabberdctl status.

Step 7 - Access Ejabberd Web Admin

You can now access the Ejabberd web admin interface via http://your_domain:5280/admin. Log in with the admin credentials you defined in the configuration file.

Conclusion

Congratulations! You have successfully installed Ejabberd on an Amazon EC2 instance. With Ejabberd, you can now build real-time applications in a highly scalable and reliable infrastructure. Explore further to see how Ejabberd’s features can enhance your data science projects.

This guide is a stepping stone in your journey of using Ejabberd in a cloud environment. Looking forward to hearing about your scaling successes!
