|
3. **Production SSL Certificate (for TURNS):**
|
|
|
|
|
Obtain an SSL certificate for your TURN domain (e.g., `turn.yourdomain.com`).
|
|
|
|
|
```bash
|
|
|
|
|
# Ensure a DNS 'A' record points turn.yourdomain.com to your server's IP
|
|
|
|
|
sudo apt install certbot
|
|
|
|
|
sudo certbot certonly --standalone -d turn.yourdomain.com
|
|
|
|
|
```
|
|
|
|
|
4. **SSL Certificate Permissions:**
|
|
|
|
|
The Coturn process (usually runs as the `turnserver` user) needs permission to read the SSL certificate and private key.
|
|
|
|
|
|
|
|
|
|
- Check current permissions:
|
|
|
|
|
```bash
|
|
|
|
|
sudo ls -lh /etc/letsencrypt/live/turn.yourdomain.com/fullchain.pem
|
|
|
|
|
sudo ls -ld /etc/letsencrypt/archive/
|
|
|
|
|
```
|
|
|
|
|
- If Coturn logs show permission errors:
|
|
|
|
|
Create a group (e.g., `ssl-cert`), add `turnserver` to it, and adjust permissions:
|
|
|
|
|
```bash
|
|
|
|
|
sudo groupadd -f ssl-cert
|
|
|
|
|
# Find the user coturn runs as, usually 'turnserver' or 'coturn'
|
|
|
|
|
# ps aux | grep turnserver
|
|
|
|
|
sudo usermod -a -G ssl-cert turnserver # Replace 'turnserver' if different
|
|
|
|
|
sudo chown -R root:ssl-cert /etc/letsencrypt/
|
|
|
|
|
sudo chmod -R 750 /etc/letsencrypt/
|
|
|
|
|
```
|
|
|
|
|
Verify the new permissions on `/etc/letsencrypt/archive/` and `/etc/letsencrypt/live/`.
|
|
|
|
|
|
|
|
|
|
5. **Configure and Start Coturn:**
|
|
|
|
|
|
|
|
|
|
- Configure `TURN_*` related environment variables in the backend's `.env` file (e.g., username, password, certificate paths).
|
|
|
|
|
- For a **testing environment**, you need to set:
|
|
|
|
|
```
|
|
|
|
|
TURN_EXTERNAL_IP=YourServerPublicIP # e.g., 123.123.456.567
|
|
|
|
|
TURN_REALM=YourServerPublicIP
|
|
|
|
|
TURN_USERNAME=YourTurnUsername
|
|
|
|
|
TURN_PASSWORD=YourTurnPassword
|
|
|
|
|
```
|
|
|
|
|
- For a **production deployment**, you need to set:
|
|
|
|
|
```
|
|
|
|
|
TURN_EXTERNAL_IP=YourServerPublicIP # e.g., 123.123.456.567
|
|
|
|
|
TURN_REALM=turn.yourdomain
|
|
|
|
|
TURN_USERNAME=YourTurnUsername
|
|
|
|
|
TURN_PASSWORD=YourTurnPassword
|
|
|
|
|
TURN_CERT_PATH=/etc/letsencrypt/live/turn.yourdomain/fullchain.pem
|
|
|
|
|
TURN_KEY_PATH=/etc/letsencrypt/live/turn.yourdomain/privkey.pem
|
|
|
|
|
```
|
|
|
|
|
- Use the script provided in the project to generate the configuration file and start the service:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# Located in the backend/ directory
|
|
|
|
|
sudo bash ./docker/TURN/configure.sh path/to/your/.env.production
|
|
|
|
|
# For a development environment, use .env.development
|
|
|
|
|
sudo systemctl status coturn
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- Check the logs at `/var/log/turnserver.log` to confirm there are no errors.
|
|
|
|
|
|
|
|
|
|
6. **Online Testing (Optional):**
|
|
|
|
|
Use an online tool like the Metered TURN Server Tester (https://www.metered.ca/turn-server-testing):
|
|
|
|
|
|
|
|
|
|
- **For Development/Testing (non-TLS):**
|
|
|
|
|
- TURN URL: `YourServerPublicIP`
|
|
|
|
|
- TURN Port: `3478`
|
|
|
|
|
- Username: `YourTurnUsername`
|
|
|
|
|
- Password: `YourTurnPassword`
|
|
|
|
|
- **For Production (TURNS):**
|
|
|
|
|
- TURNS URL: `turn.yourdomain.com`
|
|
|
|
|
- TURNS Port: `5349`
|
|
|
|
|
- Username: `YourTurnUsername`
|
|
|
|
|
- Password: `YourTurnPassword`
|
|
|
|
|
|
|
|
|
|
A successful test should show a "Reachable" message.
|
|
|
|
|
**Engineer's Note**: Detailed production configuration for Coturn (like SSL certificates, username, password, etc.) will be handled in `Section 4: Application Deployment` alongside Nginx and the main application to ensure a streamlined and unified process.

### 4.3. Configure Nginx as a Reverse Proxy
|
|
|
|
|
|
|
|
|
|
In production, Nginx will act as the entry point for all traffic, handling SSL termination and routing requests to the correct frontend or backend service.
|
|
|
|
|
|
|
|
|
|
1. **Install Nginx:** It's recommended to install a newer version that supports HTTP/3.
|
|
|
|
|
1. **Prepare Production Environment Variables for Backend and Frontend**
|
|
|
|
|
Before deployment, ensure the production environment files for both backend and frontend are ready. You will need to copy them from the example files and modify them with your server's information.
|
|
|
|
|
|
|
|
|
|
2. **Firewall:** Ensure ports `TCP:80 (HTTP)` and `TCP/UDP:443 (HTTPS/HTTP3)` are open.
|
|
|
|
|
- **Backend Configuration:**
|
|
|
|
|
```bash
|
|
|
|
|
# From the project root
|
|
|
|
|
cp backend/.env_production_example backend/.env.production
|
|
|
|
|
```
|
|
|
|
|
Then, edit `backend/.env.production`, configuring at least `CORS_ORIGIN` to your main domain (e.g., `https://privydrop.app`) and your `REDIS` details.
|
|
|
|
|
|
|
|
|
|
3. **Main Domain SSL Certificate:** Obtain a certificate for your main domain (e.g., `yourdomain.com`).
|
|
|
|
|
- **Frontend Configuration:**
|
|
|
|
|
```bash
|
|
|
|
|
# From the project root
|
|
|
|
|
cp frontend/.env_production_example frontend/.env.production
|
|
|
|
|
```
|
|
|
|
|
Then, edit `frontend/.env.production` to set `NEXT_PUBLIC_API_URL` to your backend service domain (e.g., `https://privydrop.app`).
|
|
|
|
|
|
|
|
|
|
2. **Install Nginx:** It's recommended to install a newer version that supports HTTP/3.
|
|
|
|
|
|
|
|
|
|
3. **Firewall:** Ensure ports `TCP:80 (HTTP)` and `TCP/UDP:443 (HTTPS/HTTP3)` are open.
|
|
|
|
|
|
|
|
|
|
4. **Generate Base Nginx Configuration:**
|
|
|
|
|
The `backend/docker/Nginx/` directory provides a configuration script and template. This template uses a temporary "placeholder" certificate to ensure the Nginx configuration is valid before obtaining a real certificate.
|
|
|
|
|
|
|
|
|
|
- Now, edit the `backend/.env.production` file and add the `NGINX_*` related variables. **Do not include SSL certificate paths yet**. Example:
|
|
|
|
|
```
|
|
|
|
|
NGINX_SERVER_NAME=privydrop.app # Your main domain
|
|
|
|
|
NGINX_FRONTEND_ROOT=/path/to/your/PrivyDrop/frontend # Path to the frontend project root
|
|
|
|
|
```
|
|
|
|
|
- Execute the script to generate the Nginx configuration file:
|
|
|
|
|
```bash
|
|
|
|
|
# This script uses variables from your .env file to generate the Nginx config
|
|
|
|
|
sudo bash backend/docker/Nginx/configure.sh backend/.env.production
|
|
|
|
|
```
|
|
|
|
|
### 4.4. Use Certbot to Install a Unified SSL Certificate
|
|
|
|
|
|
|
|
|
|
With the base Nginx configuration in place, we can now use Certbot to obtain and install a real SSL certificate. We will request a single, unified certificate for all our services (main domain, www, and TURN) and let Certbot automatically update our Nginx configuration.
|
|
|
|
|
|
|
|
|
|
1. **Install Certbot's Nginx Plugin:**
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
sudo apt install python3-certbot-nginx
|
|
|
|
|
sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
4. **Nginx Configuration File:**
|
|
|
|
|
The `backend/docker/Nginx/` directory in the project provides a configuration script and template.
|
|
|
|
|
2. **Run Certbot to Request the Certificate:**
|
|
|
|
|
- This command automatically detects your Nginx configuration.
|
|
|
|
|
- The `-d` flag specifies all domains to be included in the certificate. Ensure your domains' DNS records correctly point to your server's IP.
|
|
|
|
|
- The `--deploy-hook` is a crucial parameter: it will automatically restart the Coturn service after a successful certificate renewal, applying the new certificate. This enables fully automated certificate maintenance.
|
|
|
|
|
|
|
|
|
|
- Add the `NGINX_*` related variables to your backend's `.env.production` file, including the domain, certificate paths, and the **root directory of the frontend build artifacts**. Example:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
NGINX_SERVER_NAME=yourdomain.com # The full domain name
|
|
|
|
|
NGINX_SSL_CERT=/etc/letsencrypt/live/yourdomain.com/fullchain.pem
|
|
|
|
|
NGINX_SSL_KEY=/etc/letsencrypt/live/yourdomain.com/privkey.pem
|
|
|
|
|
NGINX_FRONTEND_ROOT=/path/to/your/frontend/.next # Path to frontend build output
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
5. **Apply Configuration:** Generate the Nginx config, create a symbolic link, and restart Nginx.
|
|
|
|
|
```bash
|
|
|
|
|
# This script uses NGINX_* variables from your .env file to generate the Nginx config
|
|
|
|
|
sudo bash backend/docker/Nginx/configure.sh backend/.env.production
|
|
|
|
|
# Replace privydrop.app with your main domain
|
|
|
|
|
sudo certbot --nginx \
|
|
|
|
|
-d privydrop.app \
|
|
|
|
|
-d www.privydrop.app \
|
|
|
|
|
-d turn.privydrop.app \
|
|
|
|
|
--deploy-hook "sudo systemctl restart coturn"
|
|
|
|
|
```
|
|
|
|
|
Follow the on-screen prompts from Certbot (e.g., enter your email, agree to the ToS). Once complete, Certbot will automatically modify your Nginx configuration to enable HTTPS and reload the Nginx service.
|
|
|
|
|
|
|
|
|
|
3. **Verification and Troubleshooting (Important):**
|
|
|
|
|
First, verify that the certificate path in your Nginx configuration has been updated automatically.
|
|
|
|
|
```bash
|
|
|
|
|
sudo grep ssl_certificate /etc/nginx/sites-available/default
|
|
|
|
|
```
|
|
|
|
|
You should see a path pointing to `/etc/letsencrypt/live/privydrop.app/`.
|
|
|
|
|
|
|
|
|
|
If, after running `certbot --nginx`, the path still points to the old placeholder, run the following command to force the certificate installation:
|
|
|
|
|
```bash
|
|
|
|
|
sudo certbot install --cert-name privydrop.app -d privydrop.app -d www.privydrop.app -d turn.privydrop.app
|
|
|
|
|
# Then, reload Nginx to apply the changes
|
|
|
|
|
sudo systemctl reload nginx
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 4.4. Configure Environment Variables
|
|
|
|
|
### 4.5. Configure and Start the TURN Service (Production)
|
|
|
|
|
|
|
|
|
|
- **Backend:**
|
|
|
|
|
- Create a `.env.production` file in the `backend/` directory.
|
|
|
|
|
- Fill in the necessary environment variables (e.g., `BACKEND_PORT`, `REDIS_HOST`, `REDIS_PORT`, `CORS_ORIGIN`).
|
|
|
|
|
- For Nginx integration, also add `NGINX_SERVER_NAME`, `NGINX_SSL_CERT`, `NGINX_SSL_KEY`, and `NGINX_FRONTEND_ROOT`.
|
|
|
|
|
- **Frontend:**
|
|
|
|
|
- Create a `.env.production` file in the `frontend/` directory.
|
|
|
|
|
- Fill in the `NEXT_PUBLIC_API_URL` variable.
|
|
|
|
|
With the unified SSL certificate obtained, we can now complete the production configuration for the Coturn service.
|
|
|
|
|
|
|
|
|
|
### 4.5. Run the Application with PM2
|
|
|
|
|
1. **Configure Environment Variables**:
|
|
|
|
|
Open your `backend/.env.production` file and configure all `TURN_*` related variables.
|
|
|
|
|
```ini
|
|
|
|
|
# .env.production
|
|
|
|
|
|
|
|
|
|
# ... other variables ...
|
|
|
|
|
|
|
|
|
|
# TURN/STUN Server (Coturn) Configuration
|
|
|
|
|
TURN_REALM=turn.privydrop.app # Your TURN domain
|
|
|
|
|
TURN_USERNAME=YourTurnUsername # Set a secure username
|
|
|
|
|
TURN_PASSWORD=YourTurnPassword # Set a strong password
|
|
|
|
|
|
|
|
|
|
# Critical: Point to the unified certificate generated by Certbot for your main domain
|
|
|
|
|
TURN_CERT_PATH=/etc/letsencrypt/live/privydrop.app/fullchain.pem
|
|
|
|
|
TURN_KEY_PATH=/etc/letsencrypt/live/privydrop.app/privkey.pem
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
2. **Verify SSL Certificate Permissions**:
|
|
|
|
|
The Coturn process typically runs as a low-privilege user (e.g., `turnserver` or `coturn`), while certificates generated by Certbot are owned by `root`. We need to adjust permissions to allow Coturn to read the certificate.
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# (Optional) Find the user the coturn service runs as
|
|
|
|
|
# ps aux | grep turnserver
|
|
|
|
|
|
|
|
|
|
# Create a shared group and add the turnserver user to it
|
|
|
|
|
sudo groupadd -f ssl-cert
|
|
|
|
|
sudo usermod -a -G ssl-cert turnserver # Replace 'turnserver' if the user is different
|
|
|
|
|
|
|
|
|
|
# Change ownership and permissions of the certificate directories
|
|
|
|
|

3. **Generate Configuration File and Start the Service**:
|
|
|
|
|
Run the provided script, which will generate `/etc/turnserver.conf` from your `.env.production` file and restart Coturn.
|
|
|
|
|
```bash
|
|
|
|
|
# Located in the backend/ directory
|
|
|
|
|
# Use the path to your .env file
|
|
|
|
|
sudo bash ./docker/TURN/configure.sh backend/.env.production
|
|
|
|
|
```
|
|
|
|
|
4. **Check Service Status and Test Online**:
|
|
|
|
|
- Check the service status:
|
|
|
|
|
```bash
|
|
|
|
|
sudo systemctl status coturn
|
|
|
|
|
# Also, check the logs to ensure there are no permission errors
|
|
|
|
|
# sudo journalctl -u coturn -f
|
|
|
|
|
```
|
|
|
|
|
- **Online Test (Recommended)**:
|
|
|
|
|
Once the service is running, use an online tool like the [Metered TURN Server Tester](https://www.metered.ca/turn-server-testing) to verify that your TURNS service is working correctly:
|
|
|
|
|
- **TURNS URL**: `turns:turn.privydrop.app:5349` (replace with your domain)
|
|
|
|
|
- **Username**: `The username you set in your .env file`
|
|
|
|
|
- **Password**: `The password you set in your .env file`
|
|
|
|
|
|
|
|
|
|
If all checkpoints show a green "Success" or "Reachable", your TURN server is configured successfully.

- **Connection Issues:** Check firewall settings, Nginx proxy configurations, `CORS_ORIGIN` settings, and ensure all PM2 processes are running.
|
|
|
|

- **Nginx Errors:** Use `sudo nginx -t` to check syntax and review `/var/log/nginx/error.log`.

## 6. Security & Maintenance
|
|
|
|
|
|
|
|
|
|
- **SSL Certificate Renewal (Production):** You can refer to the `backend/docker/Nginx/renew_ssl.sh` script to automate renewal.
|
|
|
|
|
- **SSL Certificate Renewal:** When you successfully configure your certificate using `certbot --nginx` with the `--deploy-hook`, Certbot automatically creates a renewal task for both Nginx and Coturn. No manual intervention is required; the certificate will be renewed and applied automatically before it expires.
|
|
|
|
|
- **Firewall:** Maintain strict firewall rules, only allowing necessary ports.
