Instructions for Installing Apache Tomcat Version 11.0.7 Together with Nginx on Ubuntu OS 24.04

In this article, we'll guide you through the process of deploying a Java web application using Apache Tomcat 11.0.7 and Nginx on Ubuntu 24.04 LTS. This setup combines the backend capabilities of Tomcat with Nginx's efficiency and frontend versatility, providing a reliable and performant solution for Java web applications.

Installing and Configuring Apache Tomcat 11.0.7

1. Install OpenJDK 17, which is required to run Tomcat 11.0.7. You can install it using the following command:

1. Download Tomcat 11.0.7 from the official Apache site and extract it to its directory.
2. Create a system user, group, and home directory for Tomcat, and set the ownership and permissions of the Tomcat directory for the Tomcat user.
3. Create a systemd service file for Tomcat and set it to start and enable on boot.
4. Deploy your file to Tomcat’s directory or configure the server.xml/context.xml appropriately. Secure Tomcat by restricting admin access and enabling proper user roles.

Setting up Nginx as a Reverse Proxy

1. Install Nginx using Ubuntu’s package manager:

1. Configure Nginx to proxy HTTP and HTTPS requests to Tomcat, which typically runs on port 8080. Use the directive in an Nginx server block to forward requests.

```nginx server { listen 80; server_name your.domain.com;

} ```

Enable SSL/TLS in Nginx

Use Let's Encrypt or another certificate authority to secure your domain via HTTPS. Configure Nginx for SSL termination, forwarding decrypted requests to Tomcat.

Performance and Security Best Practices

• Tune Tomcat thread pools and connection settings based on your load.
• Use Nginx caching or compression if appropriate.
• Monitor Tomcat and Nginx logs for errors.
• Harden the server by keeping OS and packages updated on Ubuntu 24.04.
• Use firewall rules to expose only necessary ports (e.g., 80, 443 for Nginx).
• Consider configuring Nginx for rate limiting or Web Application Firewall (WAF) features.

Automate Deployment and Updates

• Use CI/CD pipelines for building and deploying the files.
• Reload Nginx configuration smoothly when changes occur.
• Manage Tomcat as a service with systemd for auto-start and restart.

Though the search results provided do not detail this specific stack setup, these recommendations are established best practices for deploying a Java web app with Tomcat behind Nginx on Ubuntu Linux distributions, and Ubuntu 24.04 will be compatible and similar in setup to previous Ubuntu LTS releases for these components.

With these steps, you can successfully deploy a Java web application using Apache Tomcat 11.0.7 and Nginx on Ubuntu 24.04 LTS. This setup offers numerous benefits, including TLS/SSL offloading with Let's Encrypt, static content delivery, protection features, GZIP compression and caching, and a better concurrency model for high-traffic apps.

In the realm of home-and-garden for tech enthusiasts, this elucidation encompasses more than just deploying a Java web application. It delves into data-and-cloud-computing aspects, as the use of CI/CD pipelines and efficient configuration management contributes to an improved lifestyle by minimizing manual tasks. Furthermore, the technology employed here combines the robustness of Tomcat with Nginx's versatile efficiency, elevating your lifestyle by offering a reliable and performant solution for Java web applications.
