How to Install Prosody IM on Ubuntu Server Latest?

In this tutorial, we will be installing Prosody IM on Ubuntu Server latest version. Prosody is a lightweight and powerful XMPP server written in Lua. It is easy to set up and manage, offers good security and performance, and provides a flexible and extensible platform for building XMPP-based applications.

Prerequisites

Before we begin with the installation process, make sure that you have a few things ready.

1. A Server running Ubuntu 20.04 LTS
2. A non-root user with sudo privileges
3. A SSH Terminal Client like Putty, Secure CRT, etc.

Step 1: Update the System

Before installing any package or software, ensure that your system is updated. For that, run the following command:

sudo apt update && sudo apt upgrade -y

Step 2: Install Dependencies

To install dependencies, run the below command:

sudo apt-get install lua5.2 liblua5.2-dev lua-socket lua-sec luarocks

Step 3: Download and Install Prosody

To download Prosody IM:

wget https://prosody.im/files/prosody-0.11.9.tar.gz

Unpack the tarball with the following command:

tar -zxvf prosody-0.11.9.tar.gz

Change to the Prosody directory:

cd prosody-0.11.9

Then, compile and install with the following command:

./configure && make && sudo make install

Step 4: Configure Prosody

To configure Prosody, create a new file /etc/prosody/prosody.cfg.lua and add the following configuration:

admins = { "admin@your_domain.com" }

modules_enabled = {

"roster"; -- Allow users to have a roster. Recommended ;)

"saslauth"; -- Authentication for clients and servers. Recommended ;)

"tls"; -- Add support for secure TLS on c2s/s2s connections

"dialback"; -- s2s dialback support

"disco"; -- Service discovery

"posix"; -- POSIX functionality, sends server to background, enables syslog, etc.

}

allow_registration = false -- Disable registration.

log = {

-- Log files (change 'info' to 'debug' for debug logs):

{ levels = {min = "info"}, to = "console" }; -- Log to the console

--{ levels = {min = "info"}, to = "syslog" }; -- Log to syslog

}

VirtualHost "your_domain.com"

ssl = {

  key = "/etc/prosody/certs/your_domain.com.key";

  certificate = "/etc/prosody/certs/your_domain.com.crt";

}

authentication = "internal_plain"

In this configuration:

• Change the admin@your_domain.com to your own Jabber ID or email address.
• In key and certificate fields, update "your_domain.com" to match your own domain name.
• If you want information to be logged to syslog, uncomment the second log line.
• If you want to enable user registration, set allow_registration to true.

Step 5: Create SSL certificates

To create SSL certificates, run the following command:

sudo mkdir /etc/prosody/certs

Then, generate a self-signed SSL certificate by running the following command:

sudo openssl req -new -x509 -nodes -newkey rsa:4096 -keyout /etc/prosody/certs/your_domain.com.key -out /etc/prosody/certs/your_domain.com.crt -days 365

Step 6: Start Prosody

To start Prosody, run the following command:

sudo prosodyctl start

Step 7: Test the Installation

To test the Prosody installation, open a web browser and go to https://your_domain.com:5281. A message will appear indicating that the server is running and is accessible from the web.

Congratulations! You have successfully installed Prosody on your Ubuntu Server. You can now start using Prosody to build XMPP-based applications.
