---

Quick start

Bash

# Clone this repo
$ git clone https://github.com/miroslavpejic85/mirotalksfu.git

# Go to to dir mirotalksfu
$ cd mirotalksfu

# Copy app/src/config.template.js in app/src/config.js
$ cp app/src/config.template.js app/src/config.js

# Copy .env.template to .env and edit it if needed
$ cp .env.template .env

---

Config.js

Change the ENVIRONMENT and the ANNOUNCED_IP in the app/src/config.js

JavaScript

const ENVIRONMENT = 'production';
const ANNOUNCED_IP = 'Your Server Public IPv4 or Domain';

Set the port range for WebRTC communication. This range is used for the dynamic allocation of UDP ports for media streams.

JavaScript

/*
    About:
    - Each participant requires 2 ports: one for audio and one for video.
    - The default configuration supports up to 50 participants (50 * 2 ports = 100 ports).
    - To support more participants, simply increase the port range.

    Note: 
    - When running in Docker, use 'network mode: host' for improved performance.
    - Alternatively, enable 'webRtcServerActive: true' mode for better scalability.
    - Make sure these port ranges are not blocked by the firewall, if they are, add the necessary rules
*/
const RTC_MIN_PORT = 40000;
const RTC_MAX_PORT = 40100;

// Maximum workers should not exceed available CPU cores (e.g., 4 workers max on 4-core CPU)
const NUM_WORKERS = 1;

JavaScript

{
    protocol: 'udp',
    ip: '0.0.0.0',
    announcedAddress: 'Your Server Public IPv4',
    portRange: { min: RTC_MIN_PORT, max: RTC_MAX_PORT } },
{
    protocol: 'tcp',
    ip: '0.0.0.0',
    announcedAddress: 'Your Server Public IPv4',
    portRange: { min: RTC_MIN_PORT, max: RTC_MAX_PORT } },
},

// If you are not behind a NAT
{
    protocol: 'udp',
    ip: 'Your Server Public IPv4',
    portRange: { min: RTC_MIN_PORT, max: RTC_MAX_PORT } },
},
{
    protocol: 'tcp',
    ip: 'Your Server Public IPv4',
    portRange: { min: RTC_MIN_PORT, max: RTC_MAX_PORT } },
},

FireWall

Set the inbound rules if needed

Port range	Protocol	Source	Description
3010	TCP	0.0.0.0/0	APP listen on TCP
40000-40100	TCP	0.0.0.0/0	RTC port ranges TCP
40000-40100	UDP	0.0.0.0/0	RTC port ranges UDP

Bash

# Check the firewall Status: (active/inactive)
ufw status

# If active then allow traffic
ufw allow 3010/tcp
ufw allow 40000:40100/tcp
ufw allow 40000:40100/udp

# ssh, http, https, nginx...
ufw allow 22/tcp
ufw allow 80/tcp
ufw allow 443/tcp

WebRTCServer (optional)

You can activate the WebRTCServer option by setting webRtcServerActive: true in the app/src/config.js.

Here's how it works:

• MiroTalk instantiates a Worker for each CPU.
• Each Worker has its own WebRTCServer, which listens on a single port starting from 40000.
• This setup simplifies port management because you only need to open ports for the number of Workers you have.

JavaScript

{
    protocol: 'udp',
    ip: '0.0.0.0',
    announcedAddress: 'Your Server Public IPv4',
    portRange: { min: RTC_MIN_PORT, max: RTC_MIN_PORT + NUM_WORKERS }
},
{
    protocol: 'tcp',
    ip: '0.0.0.0',
    announcedAddress: 'Your Server Public IPv4',
    portRange: { min: RTC_MIN_PORT, max: RTC_MIN_PORT + NUM_WORKERS }
},

---

Install dependencies and start the server

Bash

# Install dependencies - be patient, the first time will take a few minutes, in the meantime have a good coffee ;)
$ npm install

# Start the server
$ npm start

Check if is correctly installed: http://YOUR.DOMAIN.NAME:3010

---

Using PM2 (Process Manager)

Bash

# Install pm2
$ npm install -g pm2

# Start the server
$ pm2 start app/src/Server.js

# Takes a snapshot
$ pm2 save

# Add it on startup
$ pm2 startup

---

Using Docker

Bash

# Install docker
$ sudo apt install -y docker.io

# Instal docker-compose
$ sudo apt install -y docker-compose

# Clone this repo
$ git clone https://github.com/miroslavpejic85/mirotalksfu.git

# Go to to dir mirotalksfu
$ cd mirotalksfu

# Copy app/src/config.template.js in app/src/config.js IMPORTANT (edit it according to your needs)
$ cp app/src/config.template.js app/src/config.js

# Copy .env.template to .env and edit it if needed
$ cp .env.template .env

# Copy docker-compose.template.yml in docker-compose.yml and customize it according to your needs if needed
$ cp docker-compose.template.yml docker-compose.yml

# Pull the official Docker image
$ docker pull mirotalk/sfu:latest

# Create and start containers (-d as daemon)
$ docker-compose up

Check if is correctly installed: http://YOUR.DOMAIN.NAME:3010

Configuring Nginx & Certbot

In order to use it without the port number and to have encrypted communications (mandatory to make it work correctly), we going to install nginx and certbot

Bash

# Install Nginx
$ sudo apt-get install -y nginx

# Install Certbot (SSL certificates)
$ sudo apt install -y snapd
$ sudo snap install core; sudo snap refresh core
$ sudo snap install --classic certbot
$ sudo ln -s /snap/bin/certbot /usr/bin/certbot

# Configure Nginx
$ sudo vim /etc/nginx/sites-enabled/default

Add the following:

Bash

# HTTP — redirect all traffic to HTTPS
server {
    listen 80;
    listen [::]:80;
    server_name YOUR.DOMAIN.NAME;

    return 301 https://$host$request_uri;
}

Bash

# Test Nginx configuration
$ sudo nginx -t

# Enable HTTPS with Certbot (follow the instruction)
$ sudo certbot certonly --nginx

# Add Let's Encrypt configuration to Nginx
$ sudo vim /etc/nginx/sites-enabled/default

Paste this:

Bash

# MiroTalk SFU - HTTPS — proxy all requests to the Node app
server {
    # Enable HTTP/2
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name YOUR.DOMAIN.NAME;

    # Use the Let’s Encrypt certificates
    ssl_certificate /etc/letsencrypt/live/YOUR.DOMAIN.NAME/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/YOUR.DOMAIN.NAME/privkey.pem;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://localhost:3010/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Bash

# Test Nginx configuration again
$ sudo nginx -t

# Restart nginx
$ service nginx restart
$ service nginx status

# Set up auto-renewal for SSL certificates
$ sudo certbot renew --dry-run

# Show certificates
$ sudo certbot certificates

Check Your MiroTalk SFU instance: http://YOUR.DOMAIN.NAME

---

Apache Virtual Host (Alternative to Nginx)

If you prefer Apache, configure it with the equivalent settings provided in this guide.

Bash

# Install apache with certbot
$ apt install python3-certbot-apache -y

# Setting up ssl
$ certbot --apache --non-interactive --agree-tos -d YOUR.DOMAIN.NAME -m your.email.address

# Edit the apache sites
$ sudo vim /etc/apache2/sites-enabled/YOUR.DOMAIN.NAME.conf

Add the following:

Bash

# HTTP — redirect all traffic to HTTPS
<VirtualHost *:80>
    ServerName YOUR.DOMAIN.NAME
    Redirect permanent / https://YOUR.DOMAIN.NAME
</VirtualHost>

# MiroTalk SFU - HTTPS — proxy all requests to the Node app
<VirtualHost *:443>
    ServerName YOUR.DOMAIN.NAME

    # SSL Configuration
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/YOUR.DOMAIN.NAME/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/YOUR.DOMAIN.NAME/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf

    # Enable HTTP/2 support
    Protocols h2 http/1.1

    <Location />
        # Proxy Configuration for Node.js App
        ProxyPass http://localhost:3010/
        ProxyPassReverse http://localhost:3010/

        ProxyPreserveHost On

        RequestHeader set X-Forwarded-For "%{REMOTE_ADDR}s"
        RequestHeader set X-Forwarded-Proto "https"
        RequestHeader set Host "%{HTTP_HOST}s"

        # Enable WebSocket proxy support for Socket.IO
        RewriteEngine On
        RewriteCond %{HTTP:Upgrade} =websocket [NC]
        RewriteRule /(.*) ws://localhost:3010/socket.io/$1 [P,L]
        # Adjust the WebSocket path according to your Socket.IO configuration
        # For Socket.IO 3.x or higher, use /socket.io/?EIO=4&transport=websocket
    </Location>
</VirtualHost>

Bash

# Check configuration
sudo apache2ctl configtest

sudo a2enmod proxy # Enables the `mod_proxy` module, which is essential for proxying HTTP and WebSocket connections.
sudo a2enmod proxy_http # Enables the `mod_proxy_http` module, which adds support for proxying HTTP connections.
sudo a2enmod proxy_wstunnel # Enables the `mod_proxy_wstunnel` module, which provides support for tunneling WebSocket connections

# Restart apache
sudo systemctl restart apache2
