Step-by-Step Guide: Installing Apache Tomcat 10 on Ubuntu 22.04

Apache Tomcat, a widely used Java Servlet container, provides a powerful platform for deploying Java-based web applications. In this tutorial, we’ll walk through the process of installing Tomcat 10 on Ubuntu 22.04, enabling you to set up a robust environment for Java web development.

Step 1: Update Package Index

Before installing Tomcat, it’s essential to ensure that your package index is up to date. Run the following command to update the package index:

$ sudo apt update

Step 2: Install Java Development Kit (JDK)

Tomcat requires Java to run. Install the default JDK package using the following command:

$ sudo apt install default-jdk

Step 3: Download Apache Tomcat

Navigate to the official Apache Tomcat website and download the latest version of Tomcat 10. Alternatively, you can use wget to download the Tomcat archive directly from the command line:

$ wget https://downloads.apache.org/tomcat/tomcat-10/v10.x.x/bin/apache-tomcat-10.x.x.tar.gz

Replace v10.x.x with the latest version number.

Step 4: Extract Tomcat Archive

Once the download is complete, extract the Tomcat archive using the following command:

$ sudo tar -xf apache-tomcat-10.x.x.tar.gz -C /opt

Step 5: Set Environment Variables

Set the CATALINA_HOME environment variable to point to the Tomcat installation directory:

$ echo 'export CATALINA_HOME="/opt/apache-tomcat-10.x.x"' | sudo tee -a ~/.bashrc
$ source ~/.bashrc

Step 6: Start Tomcat Service

Navigate to the Tomcat bin directory and start the Tomcat service:

$ cd $CATALINA_HOME/bin
$ ./startup.sh

Step 7: Access Tomcat Web Interface

Open your web browser and navigate to http://localhost:8080 to access the Tomcat web interface. You should see the Tomcat welcome page, indicating that Tomcat has been successfully installed and is running.

Conclusion

Congratulations! You’ve successfully installed Apache Tomcat 10 on Ubuntu 22.04. With Tomcat up and running, you can now deploy and manage Java web applications with ease. Explore the features and capabilities of Tomcat to build powerful and scalable web solutions.
