🐳 Simplest Deployment Method (Docker)

If you're too lazy to set up the environment, use Docker directly:

# 1. Download project
git clone https://github.com/yourusername/claude-relay-service.git
cd claude-relay-service

# 2. One-click start
docker-compose up -d

# 3. Check if started successfully
docker-compose ps

That simple, the service is running.

📦 Manual Deployment (For Tinkerers)

Step 1: Environment Setup

Ubuntu/Debian users:

# Install Node.js
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt-get install -y nodejs

# Install Redis
sudo apt update
sudo apt install redis-server
sudo systemctl start redis-server

CentOS/RHEL users:

# Install Node.js
curl -fsSL https://rpm.nodesource.com/setup_18.x | sudo bash -
sudo yum install -y nodejs

# Install Redis
sudo yum install redis
sudo systemctl start redis

Step 2: Download and Configure

# Download project
git clone https://github.com/yourusername/claude-relay-service.git
cd claude-relay-service

# Install dependencies
npm install

# Copy configuration files (Important!)
cp config/config.example.js config/config.js
cp .env.example .env

Step 3: Configuration File Setup

Edit .env file:

# Generate these two keys randomly, but remember them
JWT_SECRET=your-super-secret-key
ENCRYPTION_KEY=32-character-encryption-key-write-randomly

# Redis configuration
REDIS_HOST=localhost
REDIS_PORT=6379
REDIS_PASSWORD=

Edit config/config.js file:

module.exports = {
  server: {
    port: 3000,          // Service port, can be changed
    host: '0.0.0.0'     // Don't change
  },
  redis: {
    host: '127.0.0.1',  // Redis address
    port: 6379          // Redis port
  },
  // Keep other configurations as default
}

Step 4: Start Service

# Initialize
npm run setup # Will randomly generate admin account password info, stored in data/Init.json

# Start service
npm run service:start:daemon   # Run in background (recommended)

# Check status
npm run service:status

---

🎮 Getting Started

1. Open Management Interface

Browser visit: http://your-server-IP:3000/web

Default admin account: Look in data/Init.json

2. Add Claude Account

This step is quite important, requires OAuth authorization:

1. Click "Claude Accounts" tab
2. If you're in China, configure proxy first (Important!)
3. Click "Add Account"
4. Click "Generate Authorization Link", will open a new page
5. Complete Claude login and authorization in the new page
6. Copy the returned Authorization Code
7. Paste to page to complete addition

Note: If you're in China, this step may require VPN.

3. Create API Key

Assign a key to each user:

1. Click "API Keys" tab
2. Click "Create New Key"
3. Give the key a name, like "Zhang San's Key"
4. Set usage limits (optional)
5. Save, note down the generated key

4. Start Using API

Now you can replace the official API with your own service:

Original request:

curl https://api.anthropic.com/v1/messages \
  -H "x-api-key: official-key" \
  -H "content-type: application/json" \
  -d '{"model":"claude-3-sonnet-20240229","messages":[{"role":"user","content":"Hello"}]}'

Current request:

curl http://your-domain:3000/api/v1/messages \
  -H "x-api-key: cr_your-created-key" \
  -H "content-type: application/json" \
  -d '{"model":"claude-3-sonnet-20240229","messages":[{"role":"user","content":"Hello"}]}'

Just change the domain and API Key to your own generated one, everything else is the same.

🛠️ Advanced Usage

Production Deployment Recommendations (Important!)

Strongly recommend using nginx reverse proxy + SSL certificate

It's recommended to use nginx reverse proxy with SSL certificate:

1. Install nginx and obtain SSL certificate

# Ubuntu/Debian
sudo apt install nginx certbot python3-certbot-nginx

# Get free SSL certificate (using Let's Encrypt as example)
sudo certbot --nginx -d your-domain.com

2. nginx configuration example

Create /etc/nginx/sites-available/claude-relay configuration file:

server {
    listen 80;
    server_name your-domain.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name your-domain.com;
    
    # SSL configuration
    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    
    # Security headers
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    add_header X-Frame-Options DENY;
    add_header X-Content-Type-Options nosniff;
    
    # Reverse proxy configuration
    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_cache_bypass $http_upgrade;
        
        # Timeout settings
        proxy_connect_timeout 60s;
        proxy_send_timeout 60s;
        proxy_read_timeout 60s;
    }
}

3. Enable configuration

# Enable site
sudo ln -s /etc/nginx/sites-available/claude-relay /etc/nginx/sites-enabled/

# Test configuration
sudo nginx -t

# Restart nginx
sudo systemctl restart nginx

4. Update service configuration

Modify your service configuration to listen only locally:

// config/config.js
module.exports = {
  server: {
    port: 3000,
    host: '127.0.0.1'  // Listen only locally, proxy through nginx
  }
  // ... other configurations
}

5. Use HTTPS API

After configuration, your API address becomes:

curl https://your-domain.com/api/v1/messages \
  -H "x-api-key: cr_your-key" \
  -H "content-type: application/json" \
  -d '{"model":"claude-3-sonnet-20240229","messages":[{"role":"user","content":"Hello"}]}'

Security advantages:

• 🔒 Data Encryption: All API requests transmitted through HTTPS encryption
• 🛡️ Hide Ports: Don't directly expose service ports, reduce attack surface
• 🚀 Better Performance: nginx's static file serving and caching capabilities
• 📊 Access Logs: nginx provides detailed access logs and monitoring

---

💡 Usage Recommendations

Account Management

• Regular Checks: Check account status weekly, handle exceptions promptly
• Reasonable Allocation: Can assign different API keys to different people, analyze usage based on different API keys

Security Recommendations

• Use HTTPS: Strongly recommend configuring nginx reverse proxy and SSL certificate to ensure secure data transmission
• Regular Backups: Back up important configurations and data
• Monitor Logs: Regularly check exception logs
• Update Keys: Regularly change JWT and encryption keys
• Firewall Settings: Only open necessary ports (80, 443), hide direct service ports

---

🆘 What to Do When You Encounter Problems?

Self-troubleshooting

1. Check Logs: Log files in logs/ directory
2. Check Configuration: Confirm configuration files are set correctly
3. Test Connectivity: Use curl to test if API is normal
4. Restart Service: Sometimes restarting fixes it
