Installing Apache Tomcat: Step-by-Step Guide for Beginners

Access the Official Apache Tomcat Website: Navigate to the Apache Tomcat homepage at https://tomcat.apache.org.

Download the Tomcat distribution: Navigate to the “Downloads” section

# wget https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.76/bin/apache-tomcat-9.0.76.tar.gz
Extract the distribution archive
# tar -xvf apache-tomcat-9.0.76.tar.gz
Start Tomcat
# sh startup.sh

Configuring Apache Tomcat to Support PHP Scripts
Download php-java bridge file

# wget https://sourceforge.net/projects/php-java-bridge/files/Binary%20package/php-java-bridge_7.2.1/JavaBridgeTemplate721.war/download

After downloading the JavaBridgeTemplatexx.war file, extract its contents and move the two essential JAR files, JavaBridge.jar and php-servlet.jar, into the lib directory of your Apache Tomcat instance.

1. To enable PHP functionality on the Tomcat server, you’ll need to configure the web.xml file appropriately. Include the necessary configuration details and ensure that index.php is set as the default welcome file. Insert the code snippet after the opening <web-app> tag in the web.xml file.

   Testing PHP Scripts on Apache Tomcat
   Go to the parent directory of your Tomcat installation and find the bin folder.
   Ensure the catalina.sh file has execution permissions.
   Place your PHP scripts in either of these directories:webapps/ROOT/
   webapps/yourapplication/index.php
   For example create  “phpinfo.php” file in webapps/ROOT/
   After creating the PHP file, restart Tomcat:

   # ./shutdown.sh

   # ./startup.sh

2. Browse  http://IP:8080/phpinfo.php OR http://domain:8080/phpinfo.php

   Conclusion
   Running PHP scripts on Apache Tomcat combines the power of a robust Java server with PHP’s versatility, eliminating the need for separate environments. This setup simplifies resource management, reduces system complexity, and enables efficient deployment of dynamic and scalable web applications.
