## 📦 Prerequisites
|
||
|
||
Before building Carbon, ensure you have the following dependencies installed:
|
||
|
||
```bash
|
||
# Update package lists
|
||
sudo apt-get update
|
||
|
||
# Install required dependencies
|
||
sudo apt-get install -y \
|
||
build-essential \
|
||
libssl-dev \
|
||
libmagic-dev \
|
||
libnghttp2-dev \
|
||
pkg-config
|
||
```
|
||
|
||
## 🚀 Installation
|
||
|
||
### Using HTTP configuration
|
||
|
||
```bash
|
||
# Clone the repository
|
||
git clone https://github.com/Azreyo/Carbon.git
|
||
cd Carbon
|
||
|
||
# Install dependencies
|
||
sudo apt-get update
|
||
sudo apt-get install -y build-essential libssl-dev libmagic-dev libnghttp2-dev
|
||
|
||
# Build the server
|
||
make
|
||
|
||
# Run the server
|
||
sudo ./server
|
||
```
|
||
|
||
### Build Options
|
||
|
||
Carbon provides multiple build configurations:
|
||
|
||
```bash
|
||
make # Standard build
|
||
make debug # Debug build with symbols
|
||
make release # Optimized release build
|
||
make clean # Clean build artifacts
|
||
```
|
||
|
||
### Manual Compilation
|
||
|
||
If you prefer manual compilation:
|
||
|
||
```bash
|
||
gcc src/server.c src/config_parser.c src/server_config.c src/websocket.c src/http2.c -o server \
|
||
-D_GNU_SOURCE \
|
||
-Wall -Wextra -O2 \
|
||
-lssl -lcrypto -lpthread -lmagic -lnghttp2
|
||
```
|
||
|
||
## ⚙️ Configuration
|
||
|
||
### SSL/TLS Setup
|
||
|
||
> **⚠️ Important**: Self-signed certificates should only be used for testing purposes. For production, use certificates from a trusted Certificate Authority like [Let's Encrypt](https://letsencrypt.org/).
|
||
|
||
```bash
|
||
# Create certificates directory
|
||
mkdir -p ssl ssl/certs ssl/key
|
||
|
||
# Generate self-signed certificate (for testing only)
|
||
openssl req -x509 -newkey rsa:2048 \
|
||
-keyout ssl/key/key.key \
|
||
-out ssl/cert/cert.pem \
|
||
-days 365 -nodes \
|
||
-subj "/C=US/ST=State/L=City/O=Organization/CN=localhost"
|
||
```
|
||
|
||
### Server Configuration
|
||
|
||
Create or edit `server.conf` in the project root. Carbon uses a traditional Linux-style configuration format with `key = value` pairs:
|
||
|
||
```conf
|
||
# Carbon Web Server Configuration File
|
||
# Lines starting with # are comments
|
||
|
||
# Server listening port
|
||
port = 443
|
||
|
||
# Enable HTTPS (requires valid certificates in certs/ directory)
|
||
use_https = true
|
||
|
||
# Log file location
|
||
log_file = log/server.log
|
||
|
||
# Maximum number of worker threads
|
||
max_threads = 4
|
||
|
||
# Server running state
|
||
running = true
|
||
|
||
# Server name or IP address (used for logging and response headers)
|
||
server_name = 10.0.0.206
|
||
|
||
# Enable verbose logging
|
||
verbose = true
|
||
|
||
# Enable HTTP/2 support (requires HTTPS)
|
||
enable_http2 = true
|
||
|
||
# Enable WebSocket support
|
||
enable_websocket = false
|
||
```
|
||
|
||
**Configuration Options:**
|
||
- `port`: HTTP port (default: 8080)
|
||
- `use_https`: Enable HTTPS - accepts: true/false, yes/no, on/off, 1/0 (requires SSL certificates)
|
||
- `https_port`: HTTPS port (default: 443)
|
||
- `enable_http2`: Enable HTTP/2 support (requires HTTPS and ALPN)
|
||
- `enable_websocket`: Enable WebSocket support (default: true)
|
||
- `log_file`: Path to log file
|
||
- `max_threads`: Number of worker threads
|
||
- `server_name`: Your domain or IP address
|
||
- `verbose`: Enable detailed logging - accepts: true/false, yes/no, on/off, 1/0
|
||
- `ssl_cert_path`: Path to ssl certificate
|
||
- `ssl_key_path`: Path to ssl key
|
||
|
||
**Note:** Boolean values are flexible and accept multiple formats:
|
||
- True: `true`, `yes`, `on`, `1`
|
||
- False: `false`, `no`, `off`, `0`
|
||
|
||
Values can optionally be quoted with single or double quotes.
|
||
|
||
### Directory Structure
|
||
|
||
Set up the required directory structure:
|
||
|
||
```bash
|
||
# Create web root and subdirectories
|
||
mkdir -p www/{css,js,images}
|
||
|
||
# Create logs directory
|
||
mkdir -p log
|
||
```
|
||
|
||
## 🎯 Usage
|
||
|
||
### Starting the Server
|
||
|
||
```bash
|
||
# Run the server
|
||
./server
|
||
|
||
# The server will start on the configured port (default: 8080)
|
||
# Access it at http://localhost:8080
|
||
```
|
||
|
||
### Firewall Configuration
|
||
|
||
If you're using UFW, allow the necessary ports:
|
||
|
||
```bash
|
||
# Allow HTTP port
|
||
sudo ufw allow 8080/tcp
|
||
|
||
# Allow HTTPS port (if using SSL)
|
||
sudo ufw allow 443/tcp
|
||
|
||
# Reload firewall
|
||
sudo ufw reload
|
||
```
|
||
|
||
### Testing
|
||
|
||
```bash
|
||
# Test HTTP endpoint
|
||
curl http://localhost:8080
|
||
|
||
# Test HTTPS endpoint (if enabled)
|
||
curl -k https://localhost:443
|
||
|
||
# Test HTTP/2 (requires HTTPS)
|
||
curl --http2 -k https://localhost:443
|
||
|
||
# Verify HTTP/2 negotiation
|
||
openssl s_client -connect localhost:443 -alpn h2 < /dev/null 2>&1 | grep "ALPN protocol"
|
||
```
|
||
|
||
### WebSocket Usage
|
||
|
||
Carbon includes full WebSocket support for real-time bidirectional communication.
|
||
|
||
**JavaScript Client Example:**
|
||
```javascript
|
||
// Connect to WebSocket server
|
||
const ws = new WebSocket('ws://localhost:8080');
|
||
|
||
// Connection opened
|
||
ws.addEventListener('open', (event) => {
|
||
console.log('Connected to server');
|
||
ws.send('Hello Server!');
|
||
});
|
||
|
||
// Listen for messages
|
||
ws.addEventListener('message', (event) => {
|
||
console.log('Message from server:', event.data);
|
||
});
|
||
|
||
// Handle errors
|
||
ws.addEventListener('error', (error) => {
|
||
console.error('WebSocket error:', error);
|
||
});
|
||
|
||
// Connection closed
|
||
ws.addEventListener('close', (event) => {
|
||
console.log('Disconnected from server');
|
||
});
|
||
```
|
||
|
||
**Secure WebSocket (wss://):**
|
||
```javascript
|
||
const wss = new WebSocket('wss://your-domain.com');
|
||
// Same API as above
|
||
```
|
||
|
||
**Testing with wscat:**
|
||
```bash
|
||
# Install wscat
|
||
npm install -g wscat
|
||
|
||
# Connect to WebSocket server
|
||
wscat -c ws://localhost:8080
|
||
|
||
# Connect to secure WebSocket
|
||
wscat -c wss://localhost:443 --no-check
|
||
|
||
# Type messages and press Enter to send
|
||
# The server will echo them back
|
||
```
|
||
|
||
**Python Client Example:**
|
||
```python
|
||
import websocket
|
||
|
||
def on_message(ws, message):
|
||
print(f"Received: {message}")
|
||
|
||
def on_open(ws):
|
||
print("Connected")
|
||
ws.send("Hello from Python!")
|
||
|
||
ws = websocket.WebSocketApp("ws://localhost:8080",
|
||
on_message=on_message,
|
||
on_open=on_open)
|
||
ws.run_forever()
|
||
```
|
||
|
||
### HTTP/2 Support
|
||
|
||
Carbon includes full HTTP/2 support with automatic protocol negotiation via ALPN.
|
||
|
||
**Features:**
|
||
- ✅ HTTP/2 server push (stream multiplexing)
|
||
- ✅ HPACK header compression
|
||
- ✅ Binary framing protocol
|
||
- ✅ Automatic fallback to HTTP/1.1
|
||
- ✅ ALPN protocol negotiation
|
||
- ✅ Server-side stream management
|
||
|
||
**Configuration:**
|
||
|
||
Enable HTTP/2 in `server.conf`:
|
||
```ini
|
||
use_https = true
|
||
enable_http2 = true
|
||
https_port = 443
|
||
```
|
||
|
||
**Testing HTTP/2:**
|
||
|
||
```bash
|
||
# Test with curl (verbose)
|
||
curl -v --http2 -k https://localhost:443/
|
||
|
||
# Check ALPN negotiation
|
||
openssl s_client -connect localhost:443 -alpn h2 < /dev/null 2>&1 | grep "ALPN protocol"
|
||
|
||
# Test with h2load (load testing)
|
||
h2load -n 1000 -c 10 https://localhost:443/
|
||
|
||
# Use the diagnostic script
|
||
./check-http2.sh
|
||
```
|
||
|
||
**Browser Support:**
|
||
|
||
All modern browsers support HTTP/2:
|
||
- ✅ Chrome/Chromium 40+
|
||
- ✅ Firefox 36+
|
||
- ✅ Safari 9+
|
||
- ✅ Edge (all versions)
|
||
- ✅ Opera 27+
|
||
|
||
Browsers automatically negotiate HTTP/2 when connecting to HTTPS sites that support it.
|
||
|
||
**Performance Benefits:**
|
||
|
||
HTTP/2 provides significant performance improvements:
|
||
- **Multiplexing**: Multiple requests over a single connection
|
||
- **Header Compression**: Reduced overhead with HPACK
|
||
- **Server Push**: Proactive resource delivery
|
||
- **Binary Protocol**: More efficient parsing
|
||
- **Stream Prioritization**: Better resource loading

|
||
- ✅ **Obtain proper SSL certificates** from Let's Encrypt or another CA
|
||
- ✅ **Keep dependencies updated** regularly
|
||
- ✅ **Monitor server logs** for suspicious activity
|
||
- ✅ **Conduct regular security audits**
|
||
- ✅ **Implement firewall rules** to restrict access
|
||
- ✅ **Use strong passwords** and authentication mechanisms
|
||
|
||
**Reporting Security Issues**: Please report security vulnerabilities to the maintainers privately before public disclosure.
