Domain Management

Domain management covers adding and configuring domains, subdomains, and domain aliases for hosting subscriptions.

Overview

Domains

The domain table shows all configured domains:

Column	Description
Domain	Full domain name
Type	Primary domain, Additional domain, or Alias
Customer	Assigned customer
Site	Associated website
SSL	SSL status (active/inactive)
DKIM	DKIM status
Created	Creation date

---

Add Domain

1. Click Add Domain
2. Fill out the form:

Field	Required	Description
Subscription	Yes	Associated hosting subscription
Domain	Yes	Domain name (e.g. example.com)
Website	Yes	Assign to an associated website

1. Click Add

The system automatically configures:

• Nginx vhost entry for the domain
• DNS zone in PowerDNS (if enabled)
• SSL certificate via Let's Encrypt

DNS Settings

Make sure the domain's DNS records point to your server before requesting an SSL certificate.

Domain Redirect

Domains can be configured as redirects. No web space is needed — the domain redirects directly to the target URL.

Set Up a Redirect

1. Create a domain or edit an existing one
2. Set the Status to Redirect
3. Enter the Redirect URL (e.g. https://new-domain.com)
4. Select the Redirect Type:

Type	Description
301 — Permanent	Search engines adopt the new URL permanently. Recommended for permanent moves.
302 — Temporary	Search engines keep the old URL. For temporary redirects.

1. Click Save

The system automatically creates an Nginx vhost that performs the redirect. No Linux user, PHP-FPM pool, or document root required.

SSL for Redirects

Redirect domains can have SSL certificates. This is important so that https://old-domain.com correctly redirects to the target URL without a browser error.

1. Navigate to SSL Certificates
2. Find the redirect domain
3. Click Enable SSL

ACME Challenge

The redirect vhost includes a /.well-known/acme-challenge/ location so Let's Encrypt can issue the certificate before the redirect becomes active.

Changing Status

When a redirect is no longer needed, change the status back to Active or Disabled. The redirect vhost is automatically removed.

---

Enable SSL

1. Select a domain in the table
2. Click Enable SSL
3. The system automatically requests a Let's Encrypt certificate

Prerequisites:

• The domain must point to the server via DNS (A or AAAA record)
• Port 80 must be reachable (for ACME challenge)

Automatic Renewal

SSL certificates are automatically renewed before expiration. The Certbot timer regularly checks all certificates.

---

Configure DKIM

DKIM (DomainKeys Identified Mail) digitally signs outgoing emails:

1. Select a domain
2. Click Enable DKIM
3. The system generates a DKIM key
4. The required DNS TXT record is displayed

If PowerDNS is active, the DKIM record is automatically added to the DNS zone.

Email Deliverability

Enable DKIM together with SPF and DMARC for optimal email deliverability.

---

Subdomains

Subdomains are created through the subdomain management:

Create Subdomain

1. Navigate to Subdomains
2. Click Create Subdomain

Field	Required	Description
Subdomain	Yes	Prefix (e.g. shop for shop.example.com)
Domain	Yes	Parent domain
Document Root	No	Custom directory (default: subdirectory)
PHP Version	No	Custom PHP version possible

Delete Subdomain

1. Click the Delete icon
2. Confirm the deletion

---

Domain Aliases

Domain aliases redirect a domain to an existing website:

Create Alias

1. Navigate to Domain Aliases
2. Click Create Alias

Field	Required	Description
Alias Domain	Yes	The additional domain (e.g. example.net)
Target Site	Yes	Website the alias points to
Type	Yes	Redirect (301) or Mirror

Redirect: Visitors are redirected to the primary domain via a 301 redirect.

Mirror: The website is displayed identically under both domains.

Delete Alias

1. Click the Delete icon
2. Confirm the deletion

---

Delete Domain

1. Click the Delete icon in the action column
2. Confirm the deletion

When deleting, the following are removed:

• Nginx vhost entry
• DNS zone (if present)
• SSL certificate
• DKIM configuration
