    Install and Configure Jitsi Meet on Ubuntu 20.04 Using centron Infrastructure

    Jitsi Meet is a cost-free, open-source video conferencing solution offering premium-grade features, including excellent audio fidelity, robust encryption and privacy, and cross-platform compatibility. With Jitsi Meet, launching your own video conferencing platform is simple and effective.

    Requirements

    • Fresh Ubuntu 20.04 LTS x64 system hosted via centron.
    • Minimum 2 GB RAM. Choose a High Performance Compute instance for optimal results.
    • Configured sudo user (non-root).
    • Domain (FQDN) pointing to your server’s IP.

    Example Configuration

    • Server hostname: jitsi
    • FQDN: jitsi.example.com
    • IP: 192.0.2.123

    1. Create a Swap Partition

    A 2 GB swap file helps improve system performance for 2 GB RAM servers.

    Copy Code 
    

    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

    2. Set Hostname and Domain

    Define the server’s hostname and domain before enabling HTTPS certificates from Let’s Encrypt.

    Copy Code 
    

    sudo hostnamectl set-hostname jitsi

    3. Configure Firewall Rules

    Allow required ports: OpenSSH, HTTP, HTTPS, and UDP range for media streaming.

    Copy Code 
    

    sudo ufw allow OpenSSH
sudo ufw allow http
sudo ufw allow https
sudo ufw allow in 10000:20000/udp
sudo ufw enable

    Confirm by entering y when prompted.

    4. System Update

    Update the system.

    Copy Code 
    

    sudo apt update && sudo apt upgrade -y

    5. Install OpenJDK 8 JRE

    Install Java Runtime Environment version 8 required by Jitsi Meet.

    Copy Code 
    

    sudo apt install -y openjdk-8-jre-headless
java -version

    Set JAVA_HOME environment variable:

    Copy Code 
    

    echo "JAVA_HOME=$(readlink -f /usr/bin/java | sed 's:bin/java::')" | sudo tee -a /etc/profile
source /etc/profile

    6. Install Nginx Web Server

    Nginx is required for Jitsi Meet’s web interface and will be automatically configured.

    Copy Code 
    

    sudo apt install -y nginx
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

    7. Install Jitsi Meet

    Add the official repository and install Jitsi Meet:

    Copy Code 
    

    wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add -
echo "deb https://download.jitsi.org stable/" | sudo tee -a /etc/apt/sources.list.d/jitsi-stable.list
sudo apt update
sudo apt install -y jitsi-meet

    During setup, input your domain name and select the self-signed SSL option initially.

    8. Install Let’s Encrypt SSL Certificate

    Use the following script to enable HTTPS support.

    Copy Code 
    

    sudo /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh

    Enter your email address when prompted.

    Handle Certbot Error

    If you encounter the missing python-virtualenv error, apply this workaround:

    Install certbot from the official Ubuntu repository:

    Copy Code 
    

    sudo apt install certbot

    Modify the script to replace certbot-auto with certbot:

    Copy Code 
    

    sudo sed -i 's/\.\/certbot-auto/certbot/g' /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh

    Create a symbolic link to satisfy the script’s location requirement:

    Copy Code 
    

    sudo ln -s /usr/bin/certbot /usr/sbin/certbot

    Rerun the SSL script:

    Copy Code 
    

    sudo /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh
