Load Balancing Installation

#Definitions:

JMS – Your Jeets-Meet Server

JVB – The additional Jitsi Videobridge Server

#Quick Setup

all commands are issued as root user

#Update ubuntu to the latest patches on JVB

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 -apt-get install apt-transport-https

apt update

apt upgrade

#Setup your firewall on the new videobridge-server JVB

ufw status
ufw allow ssh
ufw allow 443/tcp
ufw allow 4443/tcp
ufw allow 10000:20000/udp
ufw enable

#Setup the firewall on the jitsi-meet server where the first instance is running on JMS

ufw allow 5222/tcp
ufw reload

#Install jitsi-videobridge on the new videobridge-server JVB

apt -y install jitsi-videobridge2

enter the DNS Name from your jitsi-meet server (JMS) during installation on the JVB

look into the file /etc/jitsi/videobridge/config on JVB; it should like:

# Jitsi Videobridge settings # sets the XMPP domain (default: none)JVB_HOSTNAME=<your jitsi-meet domain name which you entered during installation> # sets the hostname of the XMPP server (default: domain if set, localhost otherwise)JVB_HOST= # sets the port of the XMPP server (default: 5275)JVB_PORT=5347 # sets the shared secret used to authenticate to the XMPP serverJVB_SECRET=fg4t55z # extra options to pass to the JVB daemonJVB_OPTS=”–apis=,” # adds java system props that are passed to jvb (default are for home and logging config file)JAVA_SYS_PROPS=”-Dnet.java.sip.communicator.SC_HOME_DIR_LOCATION=/etc/jitsi -Dnet.java.sip.communicator.SC_HOME_DIR_NAME=videobridge -Dnet.java.sip.communicator.SC_LOG_DIR_LOCATION=/var/log/jitsi -Djava.util.logging.config.file=/etc/jitsi/videobridge/logging.properties”

#Copy the values from your jitsi-meet server (JMS) to the JVB Server:

on JMS open the file /etc/jitsi/videobridge/sip-communicator.properties, copy all content to clipboard and paste it on the JVB Server also in the file /etc/jitsi/videobridge/sip-communicator.properties replacing all other in it.
the content on JVB should be like:

org.jitsi.videobridge.DISABLE_TCP_HARVESTER=trueorg.jitsi.videobridge.ENABLE_STATISTICS=trueorg.jitsi.videobridge.STATISTICS_TRANSPORT=mucorg.jitsi.videobridge.xmpp.user.shard.HOSTNAME=<your jitsi-meet Server as DNS like jitsi.example.tld>org.jitsi.videobridge.xmpp.user.shard.DOMAIN=auth.<your jitsi-meet Server as DNS like jitsi.example.tld>org.jitsi.videobridge.xmpp.user.shard.USERNAME=jvborg.jitsi.videobridge.xmpp.user.shard.PASSWORD=<secret from JMS – keep it; do not change it>org.jitsi.videobridge.xmpp.user.shard.MUC_JIDS=JvbBrewery@internal.auth.<your jitsi-meet Server as DNS like jitsi.example.tld>org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME=<any unique name here; important: unique value for each videobridge like “jvb2”>org.jitsi.videobridge.xmpp.user.shard.DISABLE_CERTIFICATE_VERIFICATION=true

the file on the JMS-Server should look nearly the same, only with a other MUC_NICKNAME (keep it from installation, it is fine).
restart the videobridge-service on JVB and you should be good to go!

/etc/init.d/jitsi-videobridge2 restart

look into the logs if all is fine. The logs are located under:

JVB: /var/log/jitsi/jvb.logJMS: /var/log/jitsi/jvb.log and most important: /var/log/jitsi/jicofo.log

in jicofo-log you should see the connecting bridges:

Jicofo INFORMATION: [30] org.jitsi.jicofo.xmpp.BaseBrewery.processInstanceStatusChanged().329 Added brewery instance: jvbbrewery@internal.auth.<your jitsi-domain>/<your JVB NICKNAME like jvb2>Jicofo INFORMATION: [30] org.jitsi.jicofo.bridge.BridgeSelector.log() Added videobridge: jvbbrewery@internal.auth.<your jitsi-domain>/<your JVB NICKNAME like jvb2> v: null

#Test

To simply test the installation, shutdown the videobridge on JMS Server and check if you still can connect to JitsiMeet and do a videomeeting. The Jicofo Service will automatically use a available server.

/etc/init.d/jitsi-videobridge2 stop
