Jitsi Meet is a free and open source video conferencing service solution that is packed with various premium features, such as superior sound quality, excellent encryption and privacy, and universal multi-platform availability. With the help of Jitsi Meet, you can easily setup a stunning video conferencing service of your own.
In this tutorial, I will guide you through the process of establishing a video conferencing service on an Ubuntu 18.04 LTS server instance using Jitsi Meet.
- A fresh Vultr Ubuntu 18.04 LTS x64 server instance with an IPv4 address
- A sudo user.
- A domain
jitsimeet.example.combeing pointed to the server instance mentioned above.
Note: When deploying on your own server instance, be sure to replace all example values with your actual ones.
Step 1: Setup a swap partition
For a machine with 2GB of memory, it’s recommended to setup a 2GB (2048M) swap partition in order to improve system performance.
sudo dd if=/dev/zero of=/swapfile count=2048 bs=1M sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab free -m
Note: If you are using a different server size, the size of the swap partition may vary.
Step 2: Setup the machine’s hostname and fully qualified domain name (FQDN)
You need to properly setup a hostname and an FQDN for the machine before you can enable HTTPS security by deploying a Let’s Encrypt HTTPS certificate.
The following commands will setup a hostname,
jitsimeet, and an FQDN,
jitsimeet.example.com, for the machine:
sudo hostnamectl set-hostname jitsimeet sudo sed -i 's/^127.0.1.1.*$/127.0.1.1 jitsimeet.example.com jitsimeet/g' /etc/hosts
Confirm the results:
hostname hostname -f
Step 3: Tweak firewall rules for running Jitsi Meet
As required by Jitsi Meet, you need to allow
HTTPS traffic, along with inbound UDP traffic on port
sudo ufw allow OpenSSH sudo ufw allow http sudo ufw allow https sudo ufw allow in 10000:20000/udp sudo ufw enable
When you see the prompt
Command may disrupt existing ssh connections. Proceed with operation (y|n)?, input
y and then press ENTER.
Step 4: Update the system
For security and performance purposes, its necessary to update the Ubuntu 18.04 LTS system to the latest status:
sudo apt update sudo apt upgrade -y && sudo shutdown -r now
During the upgrade, you may be informed that the currently installed version of the grub configuration file has been locally modified. Since we are actually not responsible for the modification, use the UP arrow to highlight the
install the package maintainer's version option, and then press ENTER.
After the system reboot, log back in as the same sudo user to move on.
Step 5: Install OpenJDK Java Runtime Environment (JRE) 8
Jitsi Meet requires Java Runtime Environment. Install OpenJDK JRE 8:
sudo apt install -y openjdk-8-jre-headless
Having OpenJDK JRE 8 installed, use the following command to verify the result:
The output will be similar to the following:
openjdk version "1.8.0_171" OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11) OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)
In addition, you can setup the
JAVA_HOME environment variable as follows:
echo "JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")" | sudo tee -a /etc/profile source /etc/profile
Step 6: Install the Nginx web server
In order to better serve Jitsi Meet, you can install an Nginx web server before actually installing Jitsi Meet:
sudo apt install -y nginx sudo systemctl start nginx.service sudo systemctl enable nginx.service
Having Nginx installed, you don’t need to manually configure it because the Jitsi Meet installer will deal with this job for you later.
Note: If Nginx or Apache is not in place, the Jitsi Meet installer will automatically install Jetty along with the Jitsi Meet program.
Step 7: Install Jitsi Meet
On a modern Ubuntu or Debian system, you can easily install Jitsi Meet using the official Jitsi deb repo.
First setup the Jitsi repository on your system:
cd wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add - sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list" sudo apt update -y
Then install the full suite of Jitsi Meet:
sudo apt install -y jitsi-meet
During the installation, when you are asked to provide the hostname of the current installation, type in the FQDN
jitsimeet.example.com you setup earlier and then press ENTER.
When you are asked about the SSL certificate, highlight the
Generate a new self-signed certificate (You will later get a chance to obtain a Let's Encrypt certificate) option and then press ENTER.
Having Jitsi Meet successfully installed, use the following script to apply for a Let’s Encrypt SSL certificate:
During the process, input your email
firstname.lastname@example.org as prompted and then press ENTER. This script will automatically handle any tasks related to the Let’s Encrypt SSL certificate.
