Step By Step Install SSL Certificate Nginx


SSL (Secure Sockets Layer) certificates are used in order to establish encrypted connections between clients and servers on the web. They are essential in order to ensure that data is being transferred securely as well as to verify the identity of the server. This article will take you through the steps of installing an SSL certificate on an Nginx webserver.

Choosing an SSL Certificate Provider

The first step towards securing your website is to find and purchase an SSL certificate from a trusted provider. There are many providers out there, so it’s important to do research before making a decision. Consider the option of free certificates from Let’s Encrypt or other open source solutions, or paid certificates, such as Comodo or Symantec, if you do not have the resources or technical expertise to manage the setup and installation of an SSL certificate on your own.

Generate a Certificate Signing Request (CSR)

In order to obtain an SSL certificate, you must first generate a Certificate Signing Request (CSR). This can be done using the OpenSSL command line tool. The CSR file will contain information about the certificate, such as the domain name, public key, and signature algorithm, which must be included in the request. You should also include a private key, which will be used to generate the signed certificate. Once you have generated the CSR, you should submit it to the SSL certificate provider in order to obtain your certificate.

Install SSL Certificate on Nginx

Once you have received your SSL certificate, you can begin the installation process. First, you will need to install the certificate on the webserver. This can be done by copying the certificate and private key into the Nginx configuration file. Next, you should enable HTTPS support by adding the SSL protocol and the certificate details to the server block in the Nginx configuration file. You should then test the setup by trying to connect to the server over HTTPS.

Verifying Certificate Installation

After the SSL certificate has been installed, you should verify its installation and configuration. This can be done using an online tool such as SSL Labs, which will scan the server and provide a detailed report about the certificate and HTTPS configuration. This is a good way to check that the certificate has been installed correctly and is being used properly by the server.

Optional Configuration Steps

There are a few optional configuration steps you can take in order to further improve the security and performance of your website. For instance, you may want to enable OCSP stapling in order to improve security by reducing the time needed for the browser to check the validity of the certificate. You should also enable HTTP/2 support in order to take advantage of the bandwidth savings and performance improvements that it provides. Finally, you can enable HSTS (HTTP Strict Transport Security) in order to prevent users from accessing your website over an insecure connection.


Installing an SSL certificate on an Nginx webserver can be done relatively quickly and easily. By purchasing an SSL certificate from a trusted provider, generating a Certificate Signing Request (CSR), installing the certificate, and verifying that it has been properly installed, you can enhance the security of your website and ensure that data is being transferred securely.
