What is an SSL certificate?
Secure Sockets Layer “SSL” certificate is a digital certificate that is used to encrypt and protect data transmitted between a web server and a browser. It is also known as an HTTPS certificate.
An SSL certificate provides the assurance that the website you are visiting is secure and safe to use. It also helps secure web servers, encrypt email messages, and ensure website security.
An SSL certificate can be purchased from a third-party provider, or self-signed by the website owner, or provided by Let’s Encrypt for free.
What is the Let’s Encrypt SSL certificate?
Let’s Encrypt is a free, automated, and open certificate authority that provides free certificates to people who want to protect their websites with encryption. This means that anyone can easily encrypt their website for free by using Let’s Encrypt.
Let’s Encrypt makes web security easier and more secure by allowing anyone with a domain name to obtain an SSL certificate without having to go through any complicated process or pay a lot of money.
That being said let’s see how we can install a free SSL certificate on any Vultr server.
Point your domain name to the Vultr server IP address
This is crucial, before you can install the SSL certificate on your application you have to point your domain name to your server IP address.
Without your domain name mapping to your server IP address, you can’t install an SSL certificate to your domain name.
You can point to your domain name by adding an “A” record to your domain DNS records or editing the existing one.
The A record is a DNS record type that is used to map an IP address to a domain name. So when someone types your domain name, the domain will direct him to your server application.
To point your domain name to your Vultr server simply copy the IP address of your server which you can find in our server tab in the Products panel.
Next, go to your domain admin platform and then to your domain DNS settings to create an A record or edit the existing one.
Click Add New Record > Choose A Record, type your domain name or “@” in the Host field, paste the server IP address in the Value field, and finally click the YES sign to save the record.
If there’s already an A record click in the Value field and paste the AP address of your Vultr server and save the record.
It may take some time for the new DNS record to fully propagate, so give it some time before start installing the SSL certificate.
There are small differences when installing the Let’s Encrypt SSL certificate on certain operating systems such as Ubuntu, Debian, Apache, or Nginx.
So make sure that you are following the installation process of your application operating system. You can check it from your server tab on your Vultr dashboard.
