How to Use Wildcard SSL Certificate on Multiple Servers?
Wildcard SSL certificates are becoming increasingly popular due to their ease of use and ability to secure multiple subdomains on the same domain. It allows secure connections from a single domain name to multiple servers or subdomains. It provides encryption and authentication for the server and its visitors, protecting data exchanged between them from malicious attacks.
Using this certification on multiple servers not only ensures security but also saves time and money, as you don’t have to buy separate certificates for each server. While it’s easy to install a wildcard SSL once, many website owners ask how they can install them on multiple servers.
In this article, we’ll explain how to use Wildcard SSL certificate on multiple servers in detail. So read on if you need help setting up your own multi-server setup with a Wildcard SSL!
Preparation for Installing a Wildcard SSL Certificate on Multiple Servers
A. Choosing an Appropriate Server and Software Configuration:
When you’re installing a Wildcard SSL Certificate on multiple servers, make sure to choose an appropriate server and software configuration. The server you choose has to meet all the requirements for a wild card certificate and should be installed and configured properly.
B. Acquiring Necessary Files and Generating Keys and Certificates
Once the server, domain name, and hosting provider have been identified, you must acquire all necessary files for installation. This includes obtaining a cheap wildcard SSL certificate from a trusted Certificate Authority (CA) and generating associated keys and validations on each of your servers.
C. Creating an RSA Private Key Pair
Once all the relevant information has been gathered, you must create a new RSA private key pair. The generated files should be secure and stored in a safe place. Generating an RSA private key pair involves creating two components: a public key and the associated private key. Servers use the public Key to identify your request; the private key is only used locally on your machine or server for signing certificates.
D. Downloading Required Files from the Certification Authority (CA)
Once the correct certificate has been generated and signed by the CA, it is necessary to download the required files from the CA. Depending on the type of SSL certificate you purchased, this may include a root certificate, intermediate certificates, and end-entity (domain) certificates. Usually, these will be provided as separate ZIP packages containing the files needed for installation. It’s crucial to ensure that all of these files are downloaded in preparation for installing it on multiple servers.
E. Verifying Domain Ownership
The final step in getting a wildcard SSL is verifying domain ownership. This can be done in several ways, depending on the issuing authority you choose for your certification needs. It could involve providing contact information to the issuing authority or authorizing access to specific DNS records.
Installing the Wildcard SSL Certificate on Each Server
A. Installing the Root Certificate
The first step to installing the Wildcard SSL is to install the root certificate. This process is different for each server, so follow the instructions provided by your provider. Generally, you will need to upload the root certificate file to your server and install it using a command line tool or SSL management software.
B. Installing the Intermediate Certificates
Another important step in securing your website is installing intermediate certificates. These may be provided by the issuer and must be uploaded to the web server hosting your domain. This helps ensure that all browsers recognize your certificate as valid instead of displaying security warnings.
C. Installing the SSL Certificate on each Server
Once you have received the certificate, it must be installed on each web server. Each server requires its own installation process, so it is essential to follow the instructions that came with your certificate. If you need help with the installation process, contact your hosting provider or a security specialist who can guide you through the process.
D. Verifying that The Wildcard SSL Certificate is Working Properly
Once you have installed it onto your server, it is crucial to verify that it is working properly. This will ensure that all your subdomains are secure and encrypted when visitors access them.
To confirm that it is installed correctly, use a tool such as SSL Labs’ SSL Server Test or Certspotter Site Checker. When using either service, simply enter the domain name you wish to test, and they will scan for the Wildcard Certificate and report any issues or errors.
Benefits of Using a Wildcard SSL Certificate
- It reduces the cost burden of buying and managing multiple certificates, as it covers all subdomains of your domain in one single certificate.
- Managing it is always easier than traditional certificates as you only need to purchase and manage one for a domain instead of individual certificates for each subdomain.
- You can use the same certificate on different servers without having paying any additional price. This feature makes it ideal for firms that use multiple web hosts or have cloud-based applications.
The Bottom Line
Wildcard SSL offers a cost-effective and convenient way to secure multiple subdomains and servers with one certificate. Businesses need to research the features, pricing, and compatibility of different providers before deciding on which SSL to choose. With the proper implementation, you can ensure your website is safe from malicious threats while maintaining customer trust.
