Apache Tomcat (or simply Tomcat) is an open source web server and servlet container developed by the Apache Software Foundation (ASF).

How To Secure Tomcat 10 with Apache or Nginx on Ubuntu 20.04

Apache Tomcat serves traffic unencrypted by default, including passwords or other sensitive data. To secure your Tomcat installation, you will integrate Let’s Encrypt TLS certificates to all HTTP connections. To incorporate TLS, you can set up a reverse proxy with configured certificates, which will securely negotiate with clients and hand requests to Tomcat. While TLS connections can be configured in Tomcat itself, it’s not recommended because Tomcat does not have the latest TLS standard and security updates available. In this tutorial, you will configure this connection with either Apache or Nginx. They are both widespread and well-tested, whereas software that automates Let’s Encrypt certificate provision, such as certbot, does not provide support for Tomcat. If you want to try both Apache and Nginx, you will need separate servers for each.
