    Install BigBlueButton on Ubuntu 20.04 LTS

    Before installing BigBlueButton or BBB, first you have to check the minimum server requirements. If you are not sure about number of core your server has, check server core by following command.

    $ sudo grep -c ^processor /proc/cpuinfo

    Recommended server requirements for installing BigBlueButton 2.5 for production are –

    Recommended Server Requirements for Production (BigBlueButton)

    • Ubuntu 20.04 64-bit OS running Linux kernel 5.x
    • Latest version of docker installed
    • 16 GB of memory with swap enabled
    • 8 CPU cores, with high single-thread performance
    • 500 GB of free disk space (or more) for recordings, or 50GB if session recording is disabled on the server.
    • TCP ports 80 and 443 are accessible
    • UDP ports 16384 – 32768 are accessible
    • 250 Mbits/sec bandwidth (symmetrical) or more
    • TCP port 80 and 443 are not in use by another web server or reverse proxy
    • A hostname (such as bbb.example.com) for setup of a SSL certificate
    • IPV4 and IPV6 address

    If you are just testing BigBlueButton or has very limited users, you can reduce the configuration.

    Minimum Server Requirement for Development (BigBlueButton)

    If you are setting up BigBlueButton for local development on your workstation, you can relax some of the above requirements as there will be very less users.

    • 4 CPU cores/8 GB of memory
    • Installation on a local VM container
    • 50G of disk space
    • IPV4 address only

    Recommended Cloud Configuration for BigBlueButton Installation on Ubuntu 20.04

    If you are going to install BigBluButton on Ubuntu 20 VM on Cloud server, you can follow the official recommendations to get best results. Try to choose dedicated CPU instance.

    BigBlueButton installation recommendation cloud hosting wise –

    • AWS – c5a.2xlarge (or larger)
    • Digital Ocean – c-8 compute intensive instances (or larger)
    • Hetzner – AX51 servers or CCX32 instances.

    All the installation need SSL certificate install during BigBlueButton installation on Ubuntu 20.04, regardless the environment is.

    Pre-Installation Steps

    Now, we have our Ubuntu Server ready for installation, you can install BBB on your Local machine also, but please make sure all the server requirements must be fulfilled. Map the domain name to the server IP and setup SSL.

    Install BigBlueButton on Ubuntu 20.04 LTS

    There are multiple ways to install BigBlueButton, but we are going to follow the simplest way, which is “Installation from the script”, I personally found this method is super easy. Let’s dive in then.

    Step 1: Download the BigBlueButton latest Installer Script

    In this step, we will download the installer script from the BBB repository. This script contains all the steps and commands which makes the installation process super easy. Download the installer script by running the following command.

    $ wget -qO- https://ubuntu.bigbluebutton.org/bbb-install-2.5.sh | bash -s -- -v focal-250 -s bbb.example.com -e [email protected]  -a -w -g
    
    -bbb.example.com - Replace with your subdomain or domain
    -[email protected] - replace with your email address
    -v - OS version
    -e - email
    -a - api demos
    -w - firewall
    -g - greenlight

    Wait for command finishes.

    Step 2: Check Installation Server Status

    Run the following command to check the server status.

    $ bbb-conf --check

    You should see following output.
