Automatic Deployment of Unlimited Wildcard SSL Certificates on Eenos
SSL certificates are an essential part of modern web hosting security. They protect websites, APIs, applications, and subdomains by encrypting communication between visitors and servers. Managing SSL certificates manually for multiple domains and subdomains can become complicated, especially for hosting providers managing hundreds or thousands of websites.
With the latest Eenos SSL automation improvements, wildcard SSL certificates are now the default choice for automatic SSL deployment. Eenos uses the Eenos Certbot DNS Plugin to automatically issue and install unlimited wildcard SSL certificates for hosted domains.
Wildcard SSL certificates simplify SSL management by securing the main domain and all first-level subdomains with a single certificate.
Example:
bash
example.com
*.example.com
This single certificate can secure:
bash
www.example.com
mail.example.com
shop.example.com
api.example.com
dev.example.com
without requiring separate SSL certificates for every subdomain.
Eenos Certbot DNS Plugin: Automatic Wildcard SSL Deployment
Eenos integrates with Certbot using the native Eenos DNS authentication plugin to automate wildcard certificate generation.
During SSL deployment, Eenos automatically:
- Detects the domain configuration.
- Requests a wildcard SSL certificate using DNS validation.
- Creates the required DNS TXT challenge record.
- Completes Let's Encrypt validation.
- Installs the certificate.
- Updates the web server SSL configuration.
- Reloads required services automatically.
The entire process happens without manual certificate generation or DNS record management.
Unlimited Wildcard SSL Certificates
Eenos supports unlimited wildcard SSL certificate deployment based on the Let's Encrypt certificate authority limits.
Users can automatically generate wildcard certificates for hosted domains without additional licensing costs.
Benefits include:
- Unlimited SSL certificate automation.
- Automatic wildcard certificate renewal.
- Support for unlimited subdomains.
- Reduced SSL management overhead.
- Better security coverage for hosted applications.
Wildcard SSL as the Default SSL Deployment Method
Previously, SSL deployment commonly relied on HTTP validation using the webroot method. While HTTP validation works well, wildcard certificates require DNS validation.
With Eenos, wildcard SSL is now the preferred deployment method.
When deploying SSL for:
Eenos will automatically attempt:
bash
example.com
*.example.com
Using DNS validation through the Eenos Certbot DNS plugin.
This provides complete SSL coverage for future subdomains without requiring additional certificate deployment.
Automatic Fallback for External DNS Domains
Not every domain uses Eenos-managed DNS.
For domains where DNS is hosted externally, wildcard SSL DNS validation may not be possible because Eenos cannot automatically create DNS TXT records.
In this situation, Eenos automatically falls back to HTTP-01 webroot validation.
The fallback process:
- Attempts wildcard SSL deployment using DNS validation.
- Detects unavailable DNS automation.
- Uses HTTP webroot validation.
- Installs a standard domain SSL certificate.
This ensures SSL automation continues working even when external providers manage DNS.
SSL Deployment Automation from Terminal
Eenos provides a command-line SSL deployment utility:
bash
/scripts/installautosslfordomain
This tool allows system administrators to manually trigger SSL deployment, renewal, and certificate replacement directly from the server terminal.
Example:
bash
/scripts/installautosslfordomain -d example.com
The command automatically:
- Requests a certificate.
- Deploys SSL configuration.
- Updates supported services.
- Applies the latest certificate.
Replacing Existing SSL Certificate with Wildcard SSL Certificate
Existing SSL certificates can easily be replaced with wildcard certificates.
First, remove the existing SSL deployment:
bash
/scripts/installautosslfordomain --delete example.com
Then deploy the new wildcard SSL certificate:
bash
/scripts/installautosslfordomain -d example.com
Eenos will create a new wildcard certificate:
bash
example.com
*.example.com
and update the server configuration automatically.

Why Use Wildcard SSL Certificates on Eenos?
Simplified SSL Management
Instead of managing certificates individually:
bash
www.example.com
mail.example.com
api.example.com
shop.example.com
a wildcard certificate protects all subdomains:
Better Hosting Automation
Hosting providers can deploy new websites and subdomains without waiting for additional SSL issuance.
Improved User Experience
Website owners automatically get secure HTTPS access without having to request certificates.
Reduced Administration Work
Eenos handles:
- Certificate generation.
- DNS validation.
- Installation.
- Renewal.
- Service reload.
Frequently Asked Questions (FAQ)
What is a wildcard SSL certificate?
A wildcard SSL certificate secures a domain and all of its first-level subdomains using a single certificate.
Example : *.example.com
protects: mail.example.com, www.example.com, api.example.com
Does Eenos support unlimited wildcard SSL certificates?
Yes. Eenos supports automatic deployment of unlimited wildcard SSL certificates using the Eenos Certbot DNS plugin, subject to Let's Encrypt rate limits.
Does wildcard SSL work with external DNS providers?
Eenos attempts wildcard SSL deployment first using DNS validation.
If DNS is managed externally and cannot be updated automatically, Eenos falls back to HTTP webroot validation.
How do I manually install a wildcard SSL certificate?
Run: /scripts/installautosslfordomain -d example.com
Eenos will automatically attempt wildcard certificate deployment.
How do I replace my existing SSL certificate with wildcard SSL?
- Remove the current certificate
- Then reinstall the new certificate
Does Eenos automatically renew wildcard SSL certificates?
Yes. Certificates deployed through Eenos are automatically renewed through the integrated Certbot renewal process.
Do I need to manually create DNS TXT records?
No. If the domain DNS is managed by Eenos, the Certbot DNS plugin automatically creates and removes DNS challenge records.
