You may wish to install tomcat to support secure connections over SSL, that is, via HTTPS.
This is described in the standard tomcat documentation - for tomcat 8 at https://tomcat.apache.org/tomcat-8.0-doc/ssl-howto.html - but some notes are given here to get you started.
...
A list of certificate authorities is given on in https://en.wikipedia.org/wiki/Certificate_authority.
Overview
All installations process The installation of a certificate will contain the steps:
- Obtain a certificate - whether self-signed or from a certificate authority
- Create a keystore
- Tell tomcat where to find the keystore
...
These instructions will help you get an HTTPS connection to PhixrFlowPhixFlow, using a self-signed certificate, on linux and windows. There are the two commonest platforms for PhixFlow, and the instructions are provided to help you set PhixFlow up quickly to operate securely over with HTTPS.
| Warning |
|---|
These quick start instructions will allow you to connect to PhixFlow over an HTTPS connection, but there are other security implications when setting up a production system using certificates - in particular, whether you use a certificate from a certificate authority. Therefore, you may need to check this set up against your company security policies. Consult the standard tomcat documentation for full details of alternative methods of installation. |
The examples use a Java tool called keytool, so you must have Java installed to follow thesethem.
Obtain certificate and create keystore
...
| Code Block | ||
|---|---|---|
| ||
"%JAVA_HOME%\bin\keytool" -genkey -alias tomcat -keyalg RSA -keystore C:\app\secure\keystore.jks |
Linux
| Code Block | ||
|---|---|---|
| ||
$JAVA$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore pathToKeystoreFile |
E.g.
| Code Block | ||
|---|---|---|
| ||
$JAVAsudo mkdir /opt/tomcat/secure $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore /opt/tomcat/secure/keystore.jks sudo chown -R tomcat:tomcat /opt/tomcat/secure sudo chmod 500 /opt/tomcat/secure sudo chmod 400 /opt/tomcat/secure/keystore.jks |
| Warning |
|---|
Ensure that you create your keystore in a location that is only accessible to privileged users |
To complete the command:
- Enter a keystore password when prompted - keystorePasswd
- Enter data information 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.

<!-- 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="C:\app\secure\keystore" keystorePass="Hjq43823LfgreN"
clientAuth="false" sslProtocol="TLS" /> |
| Info |
|---|
By default, tomcat uses the port 8443 for SSL connections; if you want to use a different port, update the port setting of the connection details in the server.xml file |
| Warning |
|---|
Because the password for the keystore is stored in the server.xml file, ensure that this file is only accessible to privileged users |
- Restart tomcat. PhixFlow will now be available at
| Code Block |
|---|
https://server:portNumber/webappName |
E.g.
| Code Block |
|---|
https://localhost:8443/phixflow |

Using a Certificate from a Certificate Authority
To use a certificate from a certificate authority, follow instructions in the standard tomcat documentation, e.g. the section Installing a Certificate from a Certificate Authority on the page https://tomcat.apache.org/tomcat-8.5-doc/ssl-howto.html
