How to Install BigBlueButton on NixOS Latest

Introduction

BigBlueButton is an open-source web conferencing system that enables teachers to build a virtual classroom. In this tutorial, we will explain how to install and configure BigBlueButton on NixOS Latest.

Prerequisites

Before you proceed with this tutorial, make sure you have the following:

• A server running NixOS Latest
• A user account with sudo privileges

Step 1: Install and Configure Nginx

BigBlueButton is built to run behind an Nginx server, so we need to install and configure it first.

To install Nginx, run the following command:

sudo nix-env -iA nixos.nginx

Next, we need to configure Nginx by adding a virtual host for BigBlueButton. Edit the Nginx configuration file with the following command:

sudo nano /etc/nginx/nginx.conf

Add the following block to the configuration file:

server {
    listen 80;
    server_name your.domain.com;
    location / {
        proxy_pass http://127.0.0.1:5000;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_buffering off;
        client_max_body_size 500m;
    }
}

Replace your.domain.com with your own domain name. Save and close the file.

Finally, restart Nginx for changes to take effect:

sudo systemctl restart nginx

Step 2: Install BigBlueButton

Now that we have Nginx set up, we can install BigBlueButton. To do so, run the following commands:

sudo nix-env -iA nixos-unstable.bigbluebutton
sudo nixos-rebuild switch

This will install the latest version of BigBlueButton and rebuild the system with the new package.

Step 3: Configure BigBlueButton

Once BigBlueButton is installed, we need to configure it. The configuration files are located in the /etc/bigbluebutton directory.

First, we need to set the hostname for BigBlueButton. Edit the bbb-conf file with the following command:

sudo nano /etc/bigbluebutton/bbb-conf/apply-config.sh

Locate the BIGBLUEBUTTON_HOST variable and set it to your domain name:

BIGBLUEBUTTON_HOST=your.domain.com

Save and close the file.

Next, we need to configure the Nginx proxy. Edit the nginx configuration file with the following command:

sudo nano /etc/bigbluebutton/nginx/web.nginx

Replace the server name and IP address with your own:

server {
        listen 80; ## listen for ipv4; this line is default and implied
        ## listen for ipv6
        # listen [::]:80 default_server ipv6only=on;

        server_name your.domain.com;
...
        proxy_pass http://127.0.0.1:8000;
...

Save and close the file.

Finally, we need to enable HTTPS encryption. To do so, run the following command:

sudo bbb-conf --setip your.server.ip.address --enablessl -t

Replace your.server.ip.address with the IP address of your server. This command generates a new SSL certificate for your domain, updates the Nginx configuration file to use HTTPS, and restarts Nginx to apply the changes.

Step 4: Start BigBlueButton

After completing the configuration, we can start BigBlueButton:

sudo systemctl start bigbluebutton

You can then access the BigBlueButton web interface by navigating to https://your.domain.com in a web browser.
