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="8081"

...

 port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443"
           compress="force"/>

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

...

Modify $TOMCAT/conf/web.xml to change the Tomcat session timeout period from its default value (30 mins). Find the following lines and change as needed:

<session-config>

...

	<session-

...

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:

-

Xms1024m
-Xmx1024m
-verbose:gc

-Djava.awt.headless=true

JAVA_OPTS=

'-Xms1024m -Xmx1024m

 -verbose:gc -Djava.awt.headless=

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

As the root user, install the

...

tomcat script listed

...

in tomcat service scripts and create a

...

soft link to it from the appropriate run-level directory. The actual run-level directories are specific to the particular unix variant

...

You may wish to install tomcat to support secure connections over SSL.

This is described in the standard tomcat documentation - for example https://tomcat.apache.org/tomcat-8.0-doc/ssl-howto.html - but some notes are given here to get you started.

Type of certificate

If access to PhixFlow is only intended for people in your organisation, you may wish to create a self-signed certificate. This still provides a secure connection, but this will generate security warnings when users first connect, and they will not see a padlock in the address bar of their browser. If this is not acceptable to your users or by your company policy, or if you are going to provide access to people outside your organisation, you should obtain your certificate from a certificate authority (CA).

A list of certificate authorities is given on https://en.wikipedia.org/wiki/Certificate_authority.

Overview

All installations process will contain the steps:

1. Obtain a certificate - whether self-signed or from a certificate authority
2. Create a keystore
3. Tell tomcat where to find the keystore

Quick start for HTTPS access to PhixFlow

Obtain certificate and create keystore

Using the Java tool keytool you can create a self-signed certificate and a keystore in one step.

Windows

"%JAVA_HOME%\bin\keytool" -genkey -alias tomcat -keyalg RSA -keystore pathToKeystoreFile

E.g.

"%JAVA_HOME%\bin\keytool" -genkey -alias tomcat -keyalg RSA -keystore C:\app\secure\keystore

Linux

 $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore pathToKeystoreFile

E.g.

 $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore /opt/secure/keystore

To complete the command:

• Enter a keystore password when prompted - keystorePasswd
• Enter data about your company, contact name, etc - this information will be displayed when users access PhixFlow
• Select the default option not to set a separate password for the private key; if you want to do this, consult the tomcat documentation for further details.

Edit the tomcat configuration file

Edit the tomcat configuration file $TOMCAT/conf/server.xml as follows.

• Find the connector specification like:

...

...

.

...

and update it to:

 <!-- Define a SSL/TLS HTTP/1.1 Connector on port 8443         This connector uses the NIO implementation that requires the JSSE
         style configuration. When using the APR/native implementation, the
         OpenSSL style configuration is required as described in the APR/native
         documentation -->
    <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               keystoreFile="pathToKeystoreFile" keystorePass="keystorePasswd"
               clientAuth="false" sslProtocol="TLS" />

E.g.

 <!-- Define a SSL/TLS HTTP/1.1 Connector on port 8443         This connector uses the NIO implementation that requires the JSSE
         style configuration. When using the APR/native implementation, the

    <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               keystoreFile="C:\app\secure\keystore" keystorePass="Hjq43823LfgreN"
               clientAuth="false" sslProtocol="TLS" />

• Restart tomcat. PhixFlow will now be available at

https://localhost:8443/phixflow

Remove standard HTTP access

Edit the tomcat configuration file $TOMCAT/conf/server.xml to comment out the standard connection.

• Update the connection like:

    <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

to

    <!--
         <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    -->
