Install Apache Tomcat

Pre-requisite

In order to install Apache Tomcat you need to Install a Java Runtime Environment More

Overview

Fusion Meta Data Registry is a Java application which run under a Java Web Application Server.

A number of different open source and commercial options are available, but this guide explains how to install the free to use Apache Tomcat.

Installing the Apache Tomcat

Download and install Apache Tomcat.

Choose either Tomcat 8.5 or 9.0.

Set the Java runtime options

Tomcat needs to be configured to set certain Java options when it starts. The most important is to set the amount of memory that the Fusion Registry service will be allocated. A minimum of 4GB is recommended and the following explains how to do that.

Windows

• Go to tomcat\bin folder
• Create a file called setenv.bat with the following content

set "JAVA_OPTS=-Xmx4G"

Linux

• Go to the tomcat/bin folder
• Create a file called setenv.sh with the following content (it does not need to have 'x' executable permissions, but must be readable 'r')

export JAVA_OPTS="-Xmx4G"

Special purpose Java runtime options

Other Java runtime options that can be set for special purposes and are explained in Tomcat setenv file article.

Changing the Tomcat port number (optional)

Tomcat's default configuration is to serve its applications on port 8080. That means, by default, the Fusion Registry user interface will be available on the following URL:

http://localhost:8080/FusionRegistry

You will need to choose a different port if other software on the machine is already using port 8080.

• Go to tomcat/conf folder
• Edit server.xml
• Search "Connector port"
• Replace "8080" by your port number (8081 for instance)
• Restart tomcat server.
