4. Best Practices​

4.1 Pre-operation Preparation​

  • Permission Check: Ensure you have root or sudo privileges
  • Data Backup: Back up critical data and configurations before important operations
  • Version Confirmation: Confirm current platform version and choose the correct commands

4.2 Troubleshooting Process​

  1. Check Service Status: Use systemctl status to check service status
  2. Review Log Information: Use journalctl to view detailed error information
  3. Verify System Resources: Check disk space and memory usage
  4. Network Connectivity: Confirm ports and network configuration are correct

4.3 Security Considerations​

  • Regularly backup important data and configuration files
  • Exercise caution when performing data cleanup operations in production environments
  • Record the execution time and results of important operations
  • Recommend performing restart and upgrade operations during maintenance windows
