Each line in the configuration serves a specific purpose. The comments explain the reasoning behind each setting, making it easier to customize for your specific use case.

Initial Configuration

It's recommended to test this configuration in a staging environment before deploying to production. This helps identify potential compatibility issues and allows you to benchmark performance differences.

# Common panel management commands
sudo hestiacp list
sudo hestiacp restart
sudo hestiacp v-change-web-domain-backend-tpl admin example.com PHP-8.2
sudo hestiacp status

The configuration above sets the recommended values for a VPS with 2-4GB of RAM. Adjust the memory-related settings proportionally if your server has different specifications.

Common Issues and Solutions

• Service won't start: Check the logs with journalctl -xe -u hestiacp. Common causes include port conflicts, missing configuration files, or insufficient permissions.
• High memory usage: Review the configuration for memory-related settings. Reduce worker counts or buffer sizes if running on a low-RAM VPS.
• Permission denied errors: Ensure files and directories have the correct ownership. Use chown -R to fix ownership and chmod for permissions.

Summary

You've successfully configured hestiacp on your VPS. Remember to monitor performance, keep your software updated, and maintain regular backups. If you run into issues, consult the official documentation or open a support ticket for assistance.
