Jitsi is a true open-source solution for video conferencing. Integrating with Zimbra Collaboration Suite, we have a feasible open-source collaboration solution that has been installed on Linux VPS servers.

Step 1 — Setting the System Hostname Creates jitsi and auth hostname records on an external DNS server as screenshots below

Change hostname of the machine to jitsi.cisa2380.tk.

#sudo hostnamectl set-hostname jitsi.cisa2380.tk

Ping the hostname to check it is reachable.

Step 2 — Configuring the Firewall

Allow some ports below for Jitsi services on Ubuntu Linux Firewall.

Port 80 : uses in the TLS certificate request.

Port 443: uses for the conference room creation web page.

Port 4443/tcp 10000/udp: uses to transmit and receive the encrypted call traffic.

sudo ufw allow 80/tcp

sudo ufw allow 443/tcp

sudo ufw allow 4443/tcpsudo ufw allow 10000/udp

Step 3 — Installing Jitsi Meet

First, download the Jitsi GPG key with the wget downloading utility:

#wget https://download.jitsi.org/jitsi-key.gpg.key

#sudo nano /etc/apt/sources.list.d/jitsi-stable.list to add this line below to the file for the Jitsi repository:deb https://download.jitsi.org stable/

Finally, perform a system update to collect the package list from the Jitsi repository #sudo apt update

Install Jitsi meet with the command below.

#sudo apt install jitsi-meet

Enter the domain name for your Jitsi Meet instance.

Select the option below to create and use a self-signed TLS certificate for Jitsi system.

Step 4 — Obtaining a Signed TLS Certificate

#sudo apt install certbot

#sudo apt install certbot

Step 5 — Locking Conference Creation

Allow registered users to create conference rooms by changing the information as the file below

#sudo nano /etc/prosody/conf.avail/your_domain.cfg.lua

Change authentication = “anonymous” to authentication = “internal_plain”

Then, add to the end of the file:

VirtualHost “guest.jitsi.your_domain”

    authentication = “anonymous”     c2s_require_encryption = false

Next, edit the file /etc/jitsi/meet/jitsi.your_domain-config.js 

#sudo nano /etc/jitsi/meet/jitsi.your_domain-config.js

Change this line:

// anonymousdomain: ‘guest.jitsi.your_domain’,

To: anonymousdomain: ‘guest.jitsi.your_domain’,

Open /etc/jitsi/jicofo/sip-communicator.properties:

#sudo nano /etc/jitsi/jicofo/sip-communicator.properties

Add the line below to the end of the file. org.jitsi.jicofo.auth.URL=XMPP:jitsi.your_domain

Now, Jitsi Meet is configured to require authenticated users for video conferencing.

Use the prosodyctl utility to create user and password for Jitsi users.

#sudo prosodyctl register user your_domain password

Finally, restart the Jitsi Meet services.

sudo systemctl restart prosody.service

sudo systemctl restart jicofo.service sudo systemctl restart jitsi-videobridge2.service

The Jitsi server has been installed and securely configured.
