Nginx Https Letsencrypt Setting Location

Introduction to Nginx and HTTPS

Nginx is an open source web server that is very popular in the web hosting industry. It is extremely flexible, highly reliable, and is a great choice for any website. Nginx is often used as a reverse proxy for web applications because of its performance and scalability. Along with its flexibility, Nginx also offers the capability to serve websites over an encrypted HTTPS connection. This adds an extra layer of security to your site and strengthens its security against hackers.

To enable HTTPS on Nginx, you first must obtain a digital certificate known as a TLS certificate. This certificate is issued by a certification authority (CA) and authenticated by a third-party. They validate the identity of the website or domain in order to establish trust and secure communication between the server and the client. To make the process easier, many web hosting providers offer the free Let’s Encrypt certificates that are automatically renewed every few months.

Setting Up Let’s Encrypt with Nginx

In this step, you will be installing the Let’s Encrypt software and configuring Nginx to use the HTTPS server. To get started, you will need to log in to your server as the root user, or use an SSH connection with root privileges. Once you are logged in, you can install the Let’s Encrypt software.

You can install Let’s Encrypt using your native package manager. For example, if you are using an Ubuntu or Debian server, you can use apt-get to install the software. If you are using CentOS, you can use yum. After the installation is complete, you can use the Let’s Encrypt command to generate and install a certificate. The command takes the following form:

letsencrypt certonly --cert-name example.com --webroot path/to/example.com/public_html

In the above command, you should replace the “cert-name” and “webroot” parameters with your own settings. The cert-name is your domain name, and the webroot is the directory of your website’s public HTML folder. In some cases, you may have to use the –agree-tos option to accept the terms of service.

Once Let’s Encrypt has been installed, you can configure Nginx to use the TLS certificate. You should open the main Nginx configuration file located at /etc/nginx/nginx.conf. You will need to add a few lines of configuration code to the server block for your domain. The following is an example of code that you can use to configure the HTTPS server:

listen 443 ssl;

ssl on;

ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;

ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

Once the configuration has been applied, you can test Nginx to make sure that the HTTPS server is running correctly. You can use the “nginx -t” command to do this, and then restart your Nginx server using the “service nginx reload” command.

Setting up Redirection

Once you have the HTTPS server running, you will need to configure your website’s domain to redirect all traffic to the HTTPS protocol. To do this, you can use the Nginx “return” directive in your server block configuration. This directive will redirect all traffic to the HTTPS protocol, regardless of whether it was requested via HTTP or HTTPS. The following is an example of how this can be configured:

server {

    server_name example.com www.example.com;

    listen 80;

    return 301 https://$host$request_uri;

}

Adding HSTS Header

To further improve your website’s security, you can add the HSTS header to your website’s configuration. This header is used to indicate the level of security that is being used by the website, and this information will be used by all modern browsers to ensure that HTTPS is used when accessing the website. The following is an example of how the HSTS header can be configured in Nginx:

add_header Strict-Transport-Security "max-age=31536000; includeSubdomains; preload";

Once the header has been set up, you can then restart Nginx to apply the changes. This will ensure that all requests to your website will be redirected to the HTTPS protocol.

Conclusion

Setting up HTTPS on Nginx is a relatively simple process. By using Let’s Encrypt, you can quickly and easily obtain a TLS certificate and configure your server to serve your website over an encrypted connection. You should also take measures to add security enhancements such as HSTS headers and redirects to ensure your website is as secure as possible. By following the steps outlined above, you should be able to set up HTTPS on your Nginx server in no time.
