How To Install Apache Tomcat on Ubuntu 22.04 LTS

Install Apache Tomcat on Ubuntu 22.04

In this tutorial, we will show you how to install Apache Tomcat on Ubuntu 22.04 LTS. For those of you who didn’t know, Apache Tomcat is an open-source web server that allows you to run web applications written in Java. Tomcat is a platform-independent tool and runs where Java is installed.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Apache Tomcat on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Step 4. Configure Firewall.

Now we set up an Uncomplicated Firewall (UFW) with Apache to allow public access on default web ports for 8080:

sudo ufw allow 8080/tcp
sudo ufw reload
sudo ufw enable

Step 5. Create a user for the Web Application Manager.

Now create a user for the Web Application Manager in the Tomcat Server:

sudo nano /etc/tomcat9/tomcat-users.xml

Add the following file:

<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="idroot" password="passwd"roles="admin-gui,manager-gui"/>

Save and close the file, then restart the Tomcat server to take change effect:

sudo systemctl restart tomcat9

Step 6. Accessing Apache Tomcat Web Interface.

Once successfully installed, open your web browser and access the Apache Tomcat Web interface using the URL http://Your-IP-address:8080/manager/html. You will be redirected to the following page:
