Apache Tomcat is a widely-used application server that runs Java Servlets and JavaServer Pages (JSP). While it’s a powerful tool for web developers, there may come a time when you need to uninstall it from your Ubuntu system.
Whether you’re migrating to a different server, facing compatibility issues, or simply cleaning up unused software, this guide will walk you through the process of safely removing Apache Tomcat from your Ubuntu machine.
Let’s get started.
Step 1: Stop the Tomcat Service
Before uninstalling, ensure that the Tomcat server is not running.
sudo systemctl stop tomcat
Step 2: Remove Tomcat Packages
If you installed Tomcat using the package manager, you can remove it using the following command:
sudo apt-get purge tomcat*
This command will remove all packages related to Tomcat.
Step 3: Remove Configuration and Data Files
To ensure a complete removal, delete the configuration, data, and log files.
sudo rm -rf /etc/tomcat* sudo rm -rf /var/lib/tomcat* sudo rm -rf /var/log/tomcat*
Step 4: Remove Tomcat Users and Groups
If you created a specific user and group for Tomcat, you might want to remove them as well.
sudo deluser tomcat sudo delgroup tomcat
Step 5: Check for Remaining Files
To ensure that all Tomcat-related files are removed, you can use the find command:
sudo find / -type f -name "tomcat*"
If this command returns any results, you can manually delete the listed files.
