A Complete Guide to Apache Tomcat Administration, Tuning, and Troubleshooting

What you'll learn

Understand the fundamentals of Apache Tomcat and its role in Java web application deployment.

Learn the difference between web servers, lightweight, and enterprise application servers.

Explore Tomcat's architecture, including components like Connector, Engine, Host, Context, Service, and Server.

Install and configure Apache Tomcat on local machines and cloud environments (e.g., AWS EC2).

Master Tomcat's directory structure and critical configuration files such as server.xml and web.xml.

Deploy Java web applications using hot, cold, and auto-deployment methods.

Configure data sources and connection pools at both application and global levels.

Set up and manage virtual hosting using name-based and IP-based configurations.

Enable and configure Tomcat clustering and session stickiness for high availability.

Integrate Tomcat with web servers like Apache HTTP Server (via mod_jk, mod_proxy) and Nginx.

Perform performance tuning, including memory management, thread optimization, and connection pool settings.

Configure and manage Tomcat logging for effective monitoring and troubleshooting.

Capture and analyze thread dumps and heap dumps using tools like JConsole, VisualVM, and Eclipse MAT.

Implement secure communication using self-signed and CA-signed SSL certificates.

Gain real-world experience through hands-on labs and cloud-based deployment scenarios.

Requirements

To take this course, all you need is a PC or laptop with a stable internet connection. No prior experience with Apache Tomcat or server administration is required, as the course starts from the very basics and gradually progresses to advanced topics.

For the hands-on labs, you'll have the flexibility to work with Apache Tomcat on either Windows or Linux-based systems, depending on your preference. We'll walk you through the complete process of signing up for AWS Cloud and creating a free-tier EC2 instance, enabling you to run all exercises in a real-world, cloud-hosted environment. Alternatively, you can perform the same labs on your local machine. Other than differences in path notations and execution scripts (.bat for Windows and .sh for Linux), the concepts and configurations remain consistent across platforms.

All necessary software used in this course—including Apache Tomcat and the Java Development Kit (JDK)—is open-source and free to use. Step-by-step instructions are provided for every setup and configuration task, making the course fully accessible whether you're a beginner or a working professional looking to enhance your skills.

By the end, you'll have a fully functional Tomcat environment running both locally and in the cloud, ready to support real-world application deployments and configurations.
