MiroTalk C2C Self-Hosting Guide


  • Server Selection:
  • OS: Ubuntu 22.04 LTS.
  • Node.js (LTS) and npm
  • Domain or Subdomain Name (e.g., with a DNS A record pointing to your server's IPv4 address.
  • Recommend utilizing a Turn Server the installation documentation accessible here.


Install NodeJS 18.X and npm using Node Version Manager

Quick start

# Clone the project repo
$ git clone

# Go to project dir
$ cd mirotalkc2c

# Copy .env.template in .env and customize it according to your needs if needed
$ cp .env.template .env

# Install dependencies
$ npm install

# Start the server
$ npm start

Check if is correctly installed:

Using PM2 (Process Manager)


# Install pm2
$ npm install -g pm2

# Start the server
$ pm2 start backend/server.js

# Takes a snapshot
$ pm2 save

# Add it on startup
$ pm2 startup

Using Docker


# Install docker
$ sudo apt install -y

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

# Copy .env.template in .env and customize it according to your needs 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/c2c:latest

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

Check if is correctly installed:

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

# 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:

# HTTP — redirect all traffic to HTTPS
server {
    listen 80;
    listen [::]:80;

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

Add the following:

# MiroTalk C2C - HTTPS — proxy all requests to the Node app
server {
    # Enable HTTP/2
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    # Use the Let’s Encrypt certificates
    ssl_certificate /etc/letsencrypt/live/;
    ssl_certificate_key /etc/letsencrypt/live/;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_pass http://localhost:8080/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
# 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 C2C instance:

Apache Virtual Host (Alternative to Nginx)


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

# Edit the apache sites
vim /etc/apache2/sites-enabled/

Add the following:

# HTTP — redirect all traffic to HTTPS
<VirtualHost *:80>
    Redirect permanent /

# MiroTalk C2C - HTTPS — proxy all requests to the Node app
<VirtualHost *:443>

    # SSL Configuration
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/
    SSLCertificateKeyFile /etc/letsencrypt/live/
    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:8080/
        ProxyPassReverse http://localhost:8080/

        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:8080/$1 [P,L]
        # Adjust the WebSocket path according to your Socket.IO configuration
        # For Socket.IO 3.x or higher, use /
# 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

Updating Your Instance

To keep your MiroTalk C2C instance up to date, create an update script:

$ cd
# Create a file
$ vim

For PM2:


cd mirotalkc2c
git pull
pm2 stop backend/server.js
sudo npm install
pm2 start server.js

For Docker:


cd mirotalkc2c
git pull
docker-compose down
docker-compose pull
docker images |grep '<none>' |awk '{print $3}' |xargs docker rmi
docker-compose up -d

Make the script executable:

$ chmod +x

To update your MiroTalk C2C instance to the latest version, run the script:
