Replace “server.yourdomain.com” with your actual domain name. Verify the hostname is set correctly:

hostname -f

This should return your fully qualified domain name.

Verify Network Configuration

Ensure your server has a static IP address and that DNS records correctly point to your server. You can check your current IP configuration with:

ip addr show

System Time Configuration

Accurate system time is essential for proper log records and certificate validation. Set your timezone with:

sudo timedatectl set-timezone Your/Timezone

Replace “Your/Timezone” with your appropriate timezone (e.g., Asia/Jakarta).

Disable Conflicting Services

If you have any previously installed web servers, mail servers, or other control panels, it’s best to remove them completely to prevent conflicts:

sudo apt purge apache2 nginx mysql-* postfix exim4 bind9
sudo apt autoremove -y

Create a Backup (Optional)

If you’re working with an existing server that contains important data, create a backup before proceeding:

sudo tar -czf /root/server-backup-$(date +%F).tar.gz /etc /var/www /home

Plan ahead for critical DNS changes by lowering TTL values in advance
Most changes propagate globally within 24-48 hours

DNS Record Validation

Verify your DNS configuration with these tools:

Use the “nslookup” or “dig” command from terminal:
```
dig @your-server-ip yourdomain.com any
```
Online DNS lookup tools can verify proper propagation
Check DNS resolution from multiple geographic locations

Troubleshooting DNS Issues

Common DNS problems and solutions:

Records not resolving:
- Verify nameserver configuration at your registrar
- Check that Bind service is running: systemctl status named
- Review Bind logs in /var/log/named/
Zone transfer issues:
- Check zone file syntax
- Verify secondary nameserver configurations
Propagation delays:
- Temporarily reduce TTL values
- Use DNS propagation checker tools

Proper DNS management ensures reliable access to your websites and services. By understanding these DNS management principles in HestiaCP, you can maintain full control over your domain’s name resolution system.
