Nginx Install Ssl Certificate Centos


Nginx Install Ssl Certificate Centos

Introduction

The development of the internet and its associated technologies has made secure connections a must for anyone who wants to have a website accessible to the public. A secure connection is essential for e-commerce websites that accept credit card payments and for certain banking operations. One of the most popular methods for establishing secure HTTP connections is the use of Secure Socket Layer (SSL) certificates. This article will provide an overview of the Nginx install SSL certificate in CentOS.

Setup SSL on Nginx

Before we can begin installing our Nginx SSL certificate on CentOS, we need to make sure that we have the necessary packages installed. If you are using a version of CentOS that is compatible with the EPEL repository, then you can use the command line to install the necessary packages:

sudo yum install -y nginx mod_ssl

If the EPEL repository is not available for your version of CentOS, then you will need to download the packages from the nginx.org website. Once the packages have been installed, you can start the nginx server with the following command:

sudo /opt/nginx/bin/nginx Start

Generate SSL Certificate

Now that our nginx server is running, we can generate a 2048-bit RSA private key and an SSL certificate signing request for our self-signed SSL certificate. To do this, we need to use the OpenSSL command line utility:

openssl req -newkey rsa:2048 -nodes -keyout mydomain.key -out mydomain.csr

While running the command, you will be asked a series of questions to fill out the SSL certificate signing request. Make sure to double-check all the information you provide, since any errors could cause problems when trying to install the certificate. Once you have completed the command, you will have two new files in the current directory – mydomain.key and mydomain.csr.

Install the SSL Certificate

The next step is to install the self-signed SSL certificate. To do this, we need to use the OpenSSL command line utility again:

openssl x509 -req -days 365 -in mydomain.csr -signkey mydomain.key -out mydomain.crt

This time, you will not have to provide any information; the command will automatically create a self-signed SSL certificate with the information in the certificate signing request. Once the command has completed, you should have three files in the current directory – mydomain.key, mydomain.csr, and mydomain.crt.

Configure Nginx to Use SSL

Now it’s time to configure nginx to use the certificate we generated. This can be easily done by editing the appropriate configuration file. For example, on CentOS, the default configuration file can be found at /etc/nginx/nginx.conf. The following four lines need to be added to the default configuration file in order to tell nginx to use the SSL certificate:

ssl_certificate /path/to/mydomain.crt;

ssl_certificate_key /path/to/mydomain.key;

ssl_ciphers HIGH:!aNULL:!MD5;

ssl_prefer_server_ciphers on;

Once these changes have been made, you can restart the nginx server with the command line:

sudo /opt/nginx/bin/nginx restart

Enable Forced SSL Usage

To make sure that our website is served over HTTPS instead of HTTP, we need to configure nginx to force SSL usage. This is done by editing the appropriate configuration file. Again, on CentOS, the default configuration file can be found at /etc/nginx/nginx.conf. We need to add the following two lines to the file:

server {

listen 443 ssl;

Once these changes have been made, we can restart the nginx server with the command line:

sudo /opt/nginx/bin/nginx restart

Conclusion

We have successfully installed an SSL certificate on our Nginx server running on CentOS. We’ve also configured the server to force SSL usage. As a result, our website can now be served over a secure HTTPS connection, providing extra security to our visitors. We hope this tutorial has been helpful to you as you set up an SSL certificate for your website.
