Ubuntu 18.04 Letsencrypt Nginx

What is Ubuntu and Why is it Used for Nginx?

Ubuntu is a Linux-based operating system designed for open-source use. It is regularly updated, secure, and is popular among users because it is incredibly user-friendly and cost-effective. The most recent update to the Ubuntu operating system is 18.04, and it is specifically designed to run software such as Nginx. Nginx is an open-source web server that provides features such as scalability, speed, reliability, and focused modernization. It is an ideal web server for those who need their websites to be secure and reliable.

What is the Purpose of Letsencrypt on Ubuntu?

Letsencrypt is a free, open-source certification authority (CA) that provides SSL/TLS encryption to assist in keeping website data secure. This type of encryption is invaluable for any website that requires personal data to be transferred, like online stores or banking websites. It also ensures compliance with web standards such as the Payment Card Industry Data Security Standard (PCI DSS). Without one of these secure certificates, website visitors would be warned by their browser that the website is not secure. Having a secure certificate allows the website to access visitors’ browsers data more securely.

How to Install Letsencrypt on Ubuntu 18.04 for Use With Nginx?

Installing Letsencrypt and obtaining a secure certificate is very simple. First, you’ll need to make sure you have Nginx installed on your server. Nginx will likely already be installed on your Ubuntu machine, but if not, it can be done with a simple command. Once you confirm that Nginx is installed, you’ll need to navigate to Letsencrypt’s website, where you can create an account. You’ll then need to provide the website with details about your server, such as a domain name, and then upload a verification file. Once completed, you’ll receive a certificate that needs to be validated, followed by an install which takes just a few minutes.

Testing The Installation of Letsencrypt With Nginx

Once the installation is complete, you’ll want to test the connection to ensure everything is working properly. To do this, you’ll need to run test commands via the command line. First, run Nginx –t to check for any errors. You’ll also need to run sudo certbot renew –dry-run to test for any certificate renewals. If both of these tests pass, then the connection should be secured. You can reach out to Letsencrypt’s website with any questions or issues that arise in the process.

Using Nginx and Letsencrypt Together

Once the tests have passed, you can start using Nginx and Letsencrypt together. You’ll need to configure Nginx to use the certificate and make sure it is working properly. To do this, you’ll need to modify Nginx’s configuration file and add the certificate and key paths for it to use. After this, you’ll need to configure Nginx to listen to port 443, which should be the port Letsencrypt already uses. Once these steps are complete, Nginx will be using the Letsencrypt certificate for all incoming requests.


Ubuntu 18.04 and Nginx are an ideal combination for websites that need secure and reliable hosting. The addition of Letsencrypt helps to ensure that data is transferred safely and securely, and can be easily integrated with Nginx. Installing and configuring both of these services is relatively straightforward, and there is a wealth of information available online if you’re ever stuck. With this guide, you should now have a secure, reliable website that complies with industry standards.
