How to Know Tomcat Version in Linux

Understanding Tomcat

Tomcat is a popular Java-based web server that is widely used in enterprise environments. It provides a robust and scalable platform for building and deploying web applications. In this article, we will explore how to determine the version of Tomcat installed on your Linux system.

Step 1: Check the Tomcat Installation Directory

The first step is to check the installation directory of Tomcat. You can do this by running the following command:

ls /usr/local/tomcat

This will list the directories where Tomcat is installed. The default installation directory is /usr/local/tomcat.

Step 2: Check the Tomcat Configuration File

Next, you need to check the configuration file of Tomcat. The configuration file is usually named tomcat.conf or server.xml. You can find this file in the Tomcat installation directory. Here’s how to find it:

cd /usr/local/tomcat

ls -l server.xml

Step 3: Check the Tomcat Version

Once you have found the configuration file, you can check the version of Tomcat by running the following command:

cat server.xml | grep -i version

This command will display the version of Tomcat in the server.xml file.

Step 4: Check the Tomcat Port

Another way to determine the version of Tomcat is to check the port number it is listening on. You can do this by running the following command:

netstat -tlnp | grep 8080

This command will display the port number Tomcat is listening on.

Step 5: Check the Tomcat Logs

You can also check the Tomcat logs to determine the version of Tomcat. You can do this by running the following command:

tail -f /var/log/tomcat8/server.log

This command will display the logs of Tomcat.
