How to install Jitsi Meet on Ubuntu 18.04
IntroductionJitsi is a collection of free and open-source multiplatform voice (VoIP), videoconferencing, and instant messaging applications for the web platform, Windows, Linux, macOS, iOS, and Android. The Jitsi project began with the Jitsi Desktop (previously known as SIP Communicator). With the growth of WebRTC, the project team focus shifted to the Jitsi Video bridge for allowing web-based multi-party video calling. Later the team added Jitsi Meet, a full video-conferencing application that includes web, Android, and iOS clients. Jitsi also operates meet.jit.si, a version of Jitsi Meet hosted by Jitsi for free community use. Other projects include Jigasi, lib-jitsi-meet, Jidesha, and Jitsi. This tutorial explains to you on How to install Jitsi Meet on Ubuntu 18.04 LTS server instance.
Step 1: Setup a swap partitionFor 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
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.*$/127.0.1.1 jitsimeet.example.com jitsimeet/g' /etc/hostsConfirm the results:
hostname hostname -fStep 3: Tweak firewall rules for running Jitsi Meet As required by Jitsi Meet, you need to allow OpenSSH, HTTP, and HTTPS traffic, along with inbound UDP traffic on port 10000 through port 20000:
sudo ufw allow OpenSSH sudo ufw allow http sudo ufw allow https sudo ufw allow in 10000:20000/udp sudo ufw enable
Step 4: Update the systemFor security and performance purposes, its necessary to update the Ubuntu 18.04 LTS system to the latest status:
sudo apt update sudo apt upgrade -y && sudo shutdown -r nowDuring the upgrade, you may be informed that the currently installed version of the grub configuration file has been locally modified. Since we are actually not responsible for the modification, use the UP arrow to highlight the install the package maintainer’s version option, and then press ENTER. After the system reboot, log back in as the same sudo user to move on.
Step 5: Install OpenJDK Java Runtime Environment (JRE) 8Jitsi Meet requires Java Runtime Environment. Install OpenJDK JRE 8:
sudo apt install -y openjdk-8-jre-headlessHaving OpenJDK JRE 8 installed, use the following command to verify the result:
java -versionThe output will be similar to the following:
openjdk version "1.8.0_171" OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11) OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)In addition, you can set up the JAVA_HOME environment variable as follows:
echo "JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")" | sudo tee -a /etc/profile source /etc/profile
Step 6: Install the Nginx webserverIn 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.serviceHaving 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 MeetOn 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 -yThen install the full suite of Jitsi Meet:
sudo apt install -y jitsi-meetDuring 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:
sudo /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.shDuring the process, input your email [email protected] as prompted and then press ENTER. This script will automatically handle any tasks related to the Let’s Encrypt SSL certificate. Finally, point your favorite web browser to http://jitsimeet.example.com or https://jitsimeet.example.com to access your Jitsi Meet Video conferencing service. Feel free to explore the interface. Clicking the GO button will immediately create a Video conferencing channel for you.
