Install Apache Tomcat

Overview

Fusion Registry Core, Fusion Edge Server and other modules are Java applications which run under a Java Web Application Server.

A number of different open source and commerical 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. The following explains how to set the minimim options to allocate Fusion Registry 4GB of memory.

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

export JAVA_OPTS="-Xmx4G"

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
• Restart tomcat server.
