Welcome to this hands-on lab, where we’ll configure logging in Tomcat.
We are using Apache’s Tomcat, a Java-based application platform built around deploying and managing Java Web Applications. The server provided in this lab environment is running Red Hat Enterprise 8 and has Tomcat 9 pre-installed for you. The Tomcat instance is available on port **8080**.
You will log into the server and ensure that logging is enabled and operational, and that logs are going to the correct location.
You will check that accessing the Manager App in the GUI is logging to the correct log files.
Successfully complete this lab by achieving the following learning objectives:
- Test to Ensure You Can Access the Preconfigured Tomcat Instances on Port 8080
Connect to the Tomcat GUI in a web browser by visiting the server’s public IP address on port 8080. The username and password there are the same as what’s provided for CLI access.
For example, if the server’s IP address was 184.108.40.206, then this is the URL you’d type into the browser:
You should see the Tomcat GUI.
Note: It may take from 3 to 10 mins after the Hands-On Lab has started before you can access the Tomcat servers on Port 8080.
- Examine the logging.properties File and Check for Any Incorrect Entries
logging.propertiesfile contents instruct Tomcat to log several items. For some reason not all the logs are being placed into the
If you examine the
/usr/local/tomcat9directory, you will see that an incorrect folder is receiving some of the logs.
- Fix Any Incorrect Entries in the logging.properties File
Fix any entries in the
logging.propertiesfile so that all the logs are being placed into the
Do what is required to ensure new log entries are routed correctly.
- Test to Make Sure Your Tomcat Server Is Logging Correctly
Test and ensure that all logs are now going to the correct location.
