Editor to share with you how to use Let's Encrypt on Ubuntu18.04 and 16.04LTS to protect Nginx. I hope you will learn a lot after reading this article. Let's discuss it together.

Step 1: prerequisites

Before I begin this task, I assume that I have:

Use the sudo privilege shell to access the running Ubuntu system, with the domain name registered and pointing to the public IP address of the server. For this article we use example.com and www.example.com, which points to our server, runs the nginx web server, and configures virtualhost (for example, .com) and www.example.com for port 80.

Step 2: install the let's encrypt client

You can download the certbot auto-let's encrypt client and save it in the / usr/sbin directory. Use the following command to do this.

$sudo wget https://dl.eff.org/certbot-auto-O / usr/sbin/certbot-auto$ sudo chmod axix / usr/sbin/certbot-auto

Step 3: publish ssl for nginx

Let's encrypt automates domain validation (DV) in multiple challenges. Once the certification authority (CA) has verified the authenticity of your domain, a SSL certificate will be issued.

You don't need to create a virtualhost for ssl/https, let's let's encrypt to create it. You only need to create a virtual host for port 80.

$sudo certbot-auto-nginx-d example.com-d www.example.com

The above command prompts for an email address that is used to send email alerts related to SSL renewal and expiration. In addition, there are a few questions. When finished, it will issue a SSL certificate and create a new virtual host profile on your system.

Step 4: configure SSL automatic renewal

Finally, configure the following command on the server crontab to automatically renew the SSL certificate as needed.

02 * sudo / usr/sbin/certbot-auto-Q renew has finished reading this article. I believe you have some understanding of how to use Let's Encrypt on Ubuntu18.04 and 16.04LTS to protect Nginx. If you want to know more about it, welcome to follow the industry information channel. Thank you for reading!
