SSL certificates are used to secure our website and encrypt the details sent to the server. We will use a free self-signed SSL certificate and configure the SSL certificate using the NGINX web server. We need the oracle Linux cloud instance and NGINX server up and running. This step is prerequisite for this tutorial. Please refer to below link to install the oracle Linux and NGINX server. https://www.tech4learners.com/2022/01/how-to-create-linux-instance-with-24-gb.html https://www.tech4learners.net/2022/01/install-nginx-web-server-in-linux-cloud.html Once your compute instance and NGINX are up and running, proceed with the following steps. First step is to create PRIVATE / PUBLIC keys using the openssl command. We are using the RSA algorithm as an encryption method.  Replace the <IP_ADDRESS> with your Linux instance IP ADDRESS. sudo openssl req -new -x509 -days 30 -nodes -newkey rsa:2048 -keyout private.key \-out public.crt -subj '/C=US/ST=Ca/L=Sunnydale/CN=<IP_ADDRESS>

  Step 1: Login to oracle Linux instance using SSH client. Step 2: Enter the NGINX installation command as follows. > sudo yum install nginx If you face 'No package nginx available' error, we need to install the 'EPEL' repository. To install the EPEL repo, use the below command. > sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm We can install NGINX server once EPEL is installed . Enter the command  'sudo yum install nginx' again. Wait until the installation is complete. Step 3: We need to start the NGINX server once the installation is complete. Also, we need to make NGINX startup as a service.So that we don't need to start the NGINX server manually after reboot. Command to make the NGINX as a service is as follows. > sudo systemctl enable --now nginx.service Step 4: Verify the NGINX server status using the following command. > sudo systemctl status nginx Step 5: Add the HTTP firewall for port 80 using the
