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

---

Config.js

Change the IPv4 with Your Server public IPv4 in app/src/config.js

JavaScript

const IPv4 = 'Your Server Public IPv4'; // This is your server's public IP address. If you're using AWS EC2, you'll use the Elastic IP associated with your instance, as this is the public IP that's persistent across reboots.

JavaScript

{
    protocol: "udp",
    ip: "0.0.0.0",
    announcedAddress: IPv4,
    portRange: { min: 40000, max: 40100 } },
{
    protocol: "tcp",
    ip: "0.0.0.0",
    announcedAddress: IPv4,
    portRange: { min: 40000, max: 40100 }
},

// If you are not behind a NAT
{
    protocol: "udp",
    ip: IPv4,
    portRange: { min: 40000, max: 40100 }
},
{
    protocol: "tcp",
    ip: IPv4,
    portRange: { min: 40000, max: 40100 }
},

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: IPv4,
    portRange: { min: 40000, max: 40000 + numWorkers }
},
{
    protocol: 'tcp',
    ip: '0.0.0.0',
    announcedAddress: IPv4,
    portRange: { min: 40000, max: 40000 + numWorkers }
},

---

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 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

# Edit the apache sites
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
