In this tutorial we will show you how to install and configuration of Apache Tomcat on Debian 10. For those of you who didn’t know, Apache Tomcat is an open source web server and servlet container developed by the Apache Software Foundation. It implements the Java Servlet, JavaServer Pages (JSP), Java Unified Expression Language and Java WebSocket specifications from Sun Microsystems and provides a web server environment for Java code to run in.
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 through the step by step installation Apache Tomcat 9 on a Debian 10 (Buster) server.
Install Tomcat on Debian 10
Step 1. Before we install any software, it’s important to make sure your system is up to date by running these following apt-get commands in the terminal:
Step 2. Installing Java.
Tomcat 9.0 requires Java SE 8 or later to be installed on the server. Run the following command to install the OpenJDK package:
Verify installed Java version.
For best practice, Tomcat should never be run as privileged user (root). We recommend you to create a separate system user which will run the Tomcat server. Therefore, issue the following command:
First thing to do is to go to Apache Tomcat’s download page and download the latest stable version of Apache Tomcat, At the moment of writing this article it is version 9.0.27:
Change the ownership of the extracted directory:
Make the scripts inside the bin directory executable:
sudosh-c'chmod +x /opt/tomcat/latest/bin/*.sh'
Let’s create a systemd init file so you can start/restart/stop Tomcat:
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"
Notify systemd that a new unit file exists and start the Tomcat service by typing:
You may need to allow Tomcat server requests in the firewall so that we can access the application from the external network:
Step 5. Test the Installation
Finally, open apache tomcat from your browser, go to your IP or domain with the 8080 port (because Tomcat will always run on the 8080 port) as an example: your-domain.com:8080, replace your-domain.com with your IP or domain.
Congratulation’s! You have successfully installed Tomcat. Thanks for using this tutorial for installing Apache Tomcat on Ubuntu Debian 10 Buster system. For additional help or useful information, we recommend you to check the official Apache Tomcat website.
