Core services

The current JKPanel Server environment uses Nginx for web serving, PHP-FPM for PHP runtimes, MariaDB for databases and Redis for local runtime/cache functions. Mail deployments may additionally use Postfix and Dovecot.

Service health

• Confirm the expected service is running.
• Check whether the expected socket or network port is listening.
• Review service logs before restarting repeatedly.
• Understand customer impact before stopping a production service.

Restart policy

A restart may clear a symptom without identifying its cause. Review relevant logs and configuration validation before using service restarts as a corrective action.
