JItsi Meet Multiple Videobridges with Load Balancing

Introduction

Jitsi Meet is an open-source WebRTC JavaScript application that uses Jitsi Videobridge to provide high-quality, secure, and scalable video conferences. It can be used as a replacement for popular services like Zoom, Whereby, Teams, Skype, and many others.

Requirements

• At least two Linux systems with Debian 10
• DNS Record for your domain (in our case meet.domain.com)

Installation

First of all, we prepare our system by updating all package lists and packages. To do so run the following commands.

sudo apt update && apt upgrade -y #If you are a root user, then you don't need to use Sudo

Add the Jitsi Repository

echo 'deb https://download.jitsi.org stable/' >> /etc/apt/sources.list.d/jitsi-stable.list
sudo wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | apt-key add -
sudo apt update

Install jitsi meet

Now we are ready to install Jitsi Meet by running the following command. This will install all required components for Jitsi to work, including the web component, jicofo, jitsi-videobridge and much more.

sudo apt install jitsi-meet -y

During the installation, you will be asked to enter the FQDN (Domain name) of the Jitsi Meet instance. Please be sure to enter the correct hostname (in our case meet.domain.com)

Generate a certificate

You can select the letsencrypt or choose other certificates if you.

At this point we are already able to use Jitsi Meet. You can even test it by navigating to the hostname of your Jitsi Meet instance (in our case meet.domain.com)

Load Balancing

Jitsi Meet on a single machine is fine if you only have a few videostreams but at some point, your single instance may get too busy to handle all meetings on its own.

open the file /etc/jitsi/videobridge/sip-communicator.properties. It should look similar to this.

org.ice4j.ice.harvest.DISABLE_AWS_HARVESTER=true
org.ice4j.ice.harvest.STUN_MAPPING_HARVESTER_ADDRESSES=meet-jit-si-turnrelay.jitsi.net:443
org.jitsi.videobridge.ENABLE_STATISTICS=true
org.jitsi.videobridge.STATISTICS_TRANSPORT=muc
org.jitsi.videobridge.xmpp.user.shard.HOSTNAME=localhost
org.jitsi.videobridge.xmpp.user.shard.DOMAIN=auth.meet.domain.com
org.jitsi.videobridge.xmpp.user.shard.USERNAME=jvb
org.jitsi.videobridge.xmpp.user.shard.PASSWORD=hdg6dhdD
[email protected]al.auth.meet.domain.com
org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME=4d45d5-sd44d-5sf42d-2s54-g44sds4s4fg

Add the following lines to the end of this file.

org.jitsi.videobridge.DISABLE_TCP_HARVESTER=true
org.jitsi.videobridge.xmpp.user.shard.DISABLE_CERTIFICATE_VERIFICATION=true

Modify the line org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME to this.

org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME=jvb1

Configure the second machine

Connect to the second machine, add the required repositories and install jitsi-videobridge by running the following commands.

echo 'deb https://download.jitsi.org stable/' >> /etc/apt/sources.list.d/jitsi-stable.list
wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | apt-key add -
sudo apt update
sudo apt install jitsi-videobridge2 -y

Again, you will be asked for the hostname of your installation. Please enter the FQDN of the first machine (in our case meet.domain.com)

Next, also open the file /etc/jitsi/videobridge/sip-communicator.properties and add the following lines to the end.

org.jitsi.videobridge.DISABLE_TCP_HARVESTER=true
org.jitsi.videobridge.xmpp.user.shard.DISABLE_CERTIFICATE_VERIFICATION=true

Find the line org.jitsi.videobridge.xmpp.user.shard.HOSTNAME` and set it to the `meet.domain.com of the first machine. whatever your domain is.
In addition, please change the line org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME to this.
For Short Names

org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME=jvb2

Get the credentials from First Server

On the first machine, please open the file /etc/jitsi/videobridge/config` and find the line `JVB_SECRET. Copy the password and go back to the second machine.

Replace the passwords in the following two files by the password you just copied.

/etc/jitsi/videobridge/config
/etc/jitsi/videobridge/sip-communicator.properties

Restart the services on Server 1

sudo service prosody reload
sudo service jicofo restart
sudo service jitsi-videobridge2 restart # Generally we do not recommand to start the video-bridge on the main meet server. So you can stop it.
sudo service nginx restart

Restart videobridge on Server 2

sudo service jitsi-videobridge2 restart

Done.

Check the following log files on Server 1 to verify the videobridge nodes are joined successfully.

tail -f /var/log/jitsi/jicofo.log
tail -f /var/log/jitsi/jvb.log
/var/log/prosody/prosody.log

Check the following log files on Serve 2.

tail -f /var/log/jitsi/jvb.log
