Download

The System Administrator should have set up a linked directory structure like [c:]/opt/tomcat. The details of this may differ between installations so from this point on, the “root” Tomcat tomcat directory will be referred to as $TOMCAT.

Download the appropriate version of Tomcat 8.0 from tomcat.apache.org and unpack (unzip/uncompress) into the $TOMCAT.

...

(Refer to Compatibility Guide and Upgrade Planning for supported versions).

Install

Some instructions are given here for installing tomcat, and making it run as a service. You should ensure that any installation meets with your company standards.

...

Installing on windows

Run the tomcat installation program.

Installing on unix/ linux

Install the login scripts in tomcat login scripts into the tomcat user home directory. These scripts are correct as of Tomcat 8.0 but the PhixFlow consultant you should confirm that no changes are needed because of environment differences or because of different version of Tomcat.

Installing on Windows

Run the tomcat installation program.

server.xml: Port Specification

Modify versions of tomcat.

Configure tomcat

context.xml: cache settings

The default Tomcat cache settings are insufficient for PhixFlow:

Add <Resources ... /> to at the end of the <Context/> block in context.xml so that the file looks something like this:

<Context>
    <!-- lines omitted -->
	<Resources cachingAllowed="true" cacheMaxSize="1000000" />
</Context>

server.xml: Connector settings

Edit the <Connector block in $TOMCAT/conf/server.xml to specify the port that PhixFlow will use (usually 8081). Find the following lines and change as needed to:

1. Use the required port number (port="8080"). Tomcat defaults to port 8080 for HTTP, but you may need to use a different port if you are running other web servers on the same host.
2. Enable compression (compression="force"). Compressing responses from the server is particularly important if you are going to access the PhixFlow server over a slow connection (e.g. a mobile data connection).

After editing, the <Connector/> block should look like this:

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080" protocol="HTTP/1.1"
          <Connector portconnectionTimeout="8081"
maxHttpHeaderSize="8192" …20000"
           redirectPort="8443"
           compress="force"/>

Remember to enable this port in the server’s firewall (if enabled).

...

<session-config>
	<session-timeout>1440<timeout>720</session-timeout>
</session-config>

Update <session-timeout> to the value you need, e.g. to 1440 720 (minutes i.e. 1 day12 hours).

Java and JVM Options

Download and install Java from java.com. Java JDK 1.8 is required (and version 1.8.0_74 or greater is recommended). The following JVM (Java Virtual Machine) options should be set to control (amongst other things) the amount of memory reserved for Tomcat and therefore made available for PhixFlow. The options are:

...

To set JVM options:

-XX:MaxPermSize=150mXms1024m
-Xmx1024m
-verbose:gc
-Djava.awt.headless=true

JAVA_OPTS=’'-Xms1024m -Xmx1024m -XX:MaxPermSize=150m -verbose:gc -Djava.awt.headless=true’true'

Database JDBC Drivers

The drivers needed to connect to PhixFlow’s own database are now included in within the release and do not have to be downloaded separatelypack and no action is needed.

Drivers used to connect to external databases may still have to be downloaded.

For information on using SQLServer with Integrated Authentication, see Appendix B SQLServer Integrated Authentication.

Start Tomcat

To start Tomcat:

unix> cd $TOMCAT
unix> startup.sh

Make tomcat run as a service

Windows

• Run the Tomcat Monitor.
• Right click on the Apache Tomcat icon in the system tray and select Configure …
• On the ‘General’ tab:
• Set Startup Type to Automatic.

Unix/ Linux

...

...

Note, in particular, that these instructions guide you to setting up tomcat to run as a service under the classic init mechanism on unix/ linux (System V) since this will be available on all platforms, but you should consider using Upstart, a more modern init mechanism that will be available on most modern unix/ linux distributions. Installation using upstart is widely covered on the web. Further, at some versions of tomcat, on certain unix/ linux distribution versions, tomcat can be installed with simply package commands - you can find these from a web search.

As the root user, install the “tomcat” tomcat script listed in in Appendix A in tomcat service scripts and create a softlink soft link to it from the appropriate run-level directory. The actual run-level directories are specific to the particular unix variant.
