|
||||
|
||||
## Environment Configuration
|
||||
|
||||
### Backend Environment Variables
|
||||
|
||||
Create `backend/.env` with the following configuration:
|
||||
|
||||
```env
|
||||
# Database
|
||||
MYSQL_HOST=your-mysql-host
|
||||
MYSQL_PORT=3306
|
||||
MYSQL_USER=your-username
|
||||
MYSQL_PASSWORD=your-secure-password
|
||||
MYSQL_DATABASE=project_control
|
||||
|
||||
# Redis
|
||||
REDIS_HOST=your-redis-host
|
||||
REDIS_PORT=6379
|
||||
REDIS_DB=0
|
||||
|
||||
# JWT (IMPORTANT: Generate a secure random key)
|
||||
JWT_SECRET_KEY=your-256-bit-secret-key-here
|
||||
JWT_ALGORITHM=HS256
|
||||

|
||||
|
||||
# Environment
|
||||
ENVIRONMENT=production
|
||||
DEBUG=false
|
||||
|
||||
# CORS (comma-separated origins)
|
||||
CORS_ORIGINS=["https://your-frontend-domain.com"]
|
||||
|
||||
# File Encryption (Optional - generate with provided command)
|
||||
ENCRYPTION_MASTER_KEY=
|
||||
|
||||
# Rate Limiting
|
||||
RATE_LIMIT_STANDARD=60
|
||||
RATE_LIMIT_SENSITIVE=20
|
||||
RATE_LIMIT_HEAVY=5
|
||||
```
|
||||
|
||||
### Frontend Environment Variables
|
||||
|
||||
Create `frontend/.env.production`:
|
||||
|
||||
```env
|
||||
VITE_API_URL=https://your-api-domain.com
|
||||
```
|
||||
|
||||
## Database Setup
|
||||
|
||||
### 1. Create Database
|
||||
|
||||
```sql
|
||||
CREATE DATABASE project_control CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
|
||||
CREATE USER 'pjctrl'@'%' IDENTIFIED BY 'your-secure-password';
|
||||
GRANT ALL PRIVILEGES ON project_control.* TO 'pjctrl'@'%';
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### 2. Run Migrations
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
alembic upgrade head
|
||||
```
|
||||
|
||||
## Backend Deployment
|
||||
|
||||
### Option A: Docker (Recommended)
|
||||
|
||||
```dockerfile
|
||||
# Dockerfile
|
||||
FROM python:3.11-slim
|
||||
|
||||
WORKDIR /app
|
||||
COPY requirements.txt .
|
||||
RUN pip install --no-cache-dir -r requirements.txt
|
||||
|
||||
COPY . .
|
||||
EXPOSE 8000
|
||||
|
||||
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]
|
||||
```
|
||||
|
||||
### Option B: Manual Deployment
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
|
||||
# Create virtual environment
|
||||
python -m venv venv
|
||||
source venv/bin/activate
|
||||
|
||||
# Install dependencies
|
||||
pip install -r requirements.txt
|
||||
|
||||
# Run with gunicorn (production)
|
||||
gunicorn app.main:app -w 4 -k uvicorn.workers.UvicornWorker -b 0.0.0.0:8000
|
||||
```
|
||||
|
||||
## Frontend Deployment
|
||||
|
||||
### Build for Production
|
||||
|
||||
```bash
|
||||
cd frontend
|
||||
npm install
|
||||
npm run build
|
||||
```
|
||||
|
||||
### Serve Static Files
|
||||
|
||||
The `dist/` folder contains static files that can be served by:
|
||||
- Nginx
|
||||
- Apache
|
||||
- CDN (CloudFront, Cloudflare)
|
||||
- Static hosting (Vercel, Netlify)
|
||||
|
||||
### Nginx Configuration Example
|
||||
|
||||
```nginx
|
||||
server {
|
||||
listen 80;
|
||||
server_name your-domain.com;
|
||||
|
||||
root /var/www/project-control/frontend/dist;
|
||||
index index.html;
|
||||
|
||||
# SPA routing
|
||||
location / {
|
||||
try_files $uri $uri/ /index.html;
|
||||
}
|
||||
|
||||
# API proxy
|
||||
location /api {
|
||||
proxy_pass http://localhost:8000;
|
||||
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;
|
||||
}
|
||||
|
||||
# WebSocket proxy
|
||||
location /ws {
|
||||
proxy_pass http://localhost:8000;
|
||||
proxy_http_version 1.1;
|
||||
proxy_set_header Upgrade $http_upgrade;
|
||||
proxy_set_header Connection "upgrade";
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Security Checklist
|
||||
|
||||
Before going live, ensure:
|
||||
|
||||
- [ ] `DEBUG=false` in production
|
||||
- [ ] `ENVIRONMENT=production` is set
|
||||
- [ ] Strong `JWT_SECRET_KEY` (256-bit random)
|
||||
- [ ] Database password is secure
|
||||
- [ ] CORS origins are restricted to your domain
|
||||
- [ ] HTTPS is enabled (SSL/TLS certificate)
|
||||
- [ ] Rate limiting is configured
|
||||
- [ ] File upload directory has proper permissions
|
||||
- [ ] Redis is password-protected (if exposed)
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Health Check Endpoints
|
||||
|
||||
| Endpoint | Auth | Description |
|
||||
|----------|------|-------------|
|
||||
| `GET /health` | No | Basic health status |
|
||||
| `GET /health/live` | No | Liveness probe |
|
||||
| `GET /health/ready` | No | Readiness probe |
|
||||
| `GET /health/detailed` | Admin | Detailed system status |
|
||||
|
||||
### API Documentation
|
||||
|
||||
- Swagger UI: `https://your-api-domain.com/docs`
|
||||
- ReDoc: `https://your-api-domain.com/redoc`
|
||||
|
||||
## Backup Strategy
|
||||
|
||||
### Database Backup
|
||||
|
||||
```bash
|
||||
# Daily backup
|
||||
mysqldump -h $MYSQL_HOST -u $MYSQL_USER -p$MYSQL_PASSWORD project_control > backup_$(date +%Y%m%d).sql
|
||||
```
|
||||
|
||||
### File Attachments
|
||||
|
||||
Backup the `uploads/` directory containing user attachments.
|
||||
|
||||
### Encryption Key
|
||||
|
||||
**CRITICAL**: Backup `ENCRYPTION_MASTER_KEY` securely. If lost, encrypted files cannot be recovered.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **CORS errors**: Verify `CORS_ORIGINS` includes your frontend domain
|
||||
2. **401 Unauthorized**: Check JWT token expiry and refresh token flow
|
||||
3. **WebSocket disconnects**: Ensure proxy supports WebSocket upgrade
|
||||
4. **Rate limiting**: Adjust `RATE_LIMIT_*` values if needed
|
||||
|
||||
### Logs
|
||||
|
||||
Backend logs are output to stdout. Configure your logging infrastructure to capture them.
|
||||
|
||||
```bash
|
||||
# View logs in Docker
|
||||
docker logs -f project-control-backend
|
||||
```
|
||||
|
||||
## Scaling
|
||||
|
||||
### Horizontal Scaling
|
||||
|
||||
- Backend: Run multiple instances behind a load balancer
|
||||
- Redis: Use Redis Cluster for high availability
|
||||
- Database: Use read replicas for read-heavy workloads
|
||||
|
||||
### WebSocket Considerations
|
||||
|
||||
When running multiple backend instances, ensure WebSocket connections are sticky (session affinity) or use a shared pub/sub system (Redis pub/sub is already implemented).
