Security Best Practices | 安全最佳实践

1. Never Commit Secrets

# .gitignore
.env
.env.local
.env.*.local

2. Use Strong Secrets

# Bad
JWT_SECRET=secret

# Good
JWT_SECRET=8f4e7d3c2a1b9f8e7d6c5b4a3f2e1d0c9b8a7f6e5d4c3b2a1f0e9d8c7b6a5f4e3

3. Rotate Keys Regularly

Update JWT_SECRET and API keys periodically.

4. Use Environment-Specific Values

Don't use the same secrets across environments.

5. Limit Access

Restrict who can access production environment variables.

Validation & Troubleshooting | 验证和故障排除

Check Environment Variables

// In Node.js code
console.log('PORT:', process.env.PORT);
console.log('MONGO_URL:', process.env.MONGO_URL);

Common Issues

Issue: Variables not loading

Solution:

1. Check file name is .env (not env.txt)
2. Ensure file is in project root
3. Restart server after changes
4. Check for typos in variable names

Issue: Database connection fails

Solution:

1. Verify MongoDB is running
2. Check MONGO_URL format
3. Test connection: mongo mongodb://127.0.0.1:27017/steedos
4. Check network/firewall

Issue: Redis connection fails

Solution:

1. Verify Redis is running: redis-cli ping
2. Check TRANSPORTER and CACHER URLs
3. Test connection: redis-cli -h 127.0.0.1 -p 6379 ping
