Installation Manual for Tomcat

Purpose of this document

This manual describes the installation of Web Flow including setting up the environment. The manual assumes installation on a Linux system, however installation on other OSes contains similar steps.

If you prefer a faster setup, consider trying our Docker images.

Dependencies

The Web Flow application has following dependencies which should be deployed before deploying Web Flow:

Create required user and group

Create group “tomcat” and user “tomcat”:

$ groupadd tomcat

$ useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat

$ chmod 775 tomcat

Optionally, add your user to the “tomcat” group:

$ usermod -a -G tomcat ext_johndoe

Configure Bouncy Castle Provider

Add an entry to the java.security file, where N is the last number of provider in the file incremented by one:

security.provider.N=org.bouncycastle.jce.provider.BouncyCastleProvider

A recent version of the Bouncy Castle library is bundled with Web Flow and Next Step applications.

Install Tomcat

Unzip Tomcat to “/opt/tomcat” folder. You can download Tomcat here:

https://tomcat.apache.org/download-90.cgi

Change owner of the files to “tomcat” user:

sudo chown -R tomcat:tomcat /opt/tomcat/

Customize application

Create folder “/opt/ext-resources”.

Change owner of the “/opt/ext-resources” to “tomcat:tomcat”:

$ sudo chown -R tomcat:tomcat /opt/ext-resources/

$ sudo chmod -R 775 /opt/ext-resources/

$ sudo chmod -R -x+X /opt/ext-resources/

Copy all resources which you want to modify into this folder. See resources in the powerauth-webflow-customization project which contains original resources which can be modified for the concrete installation.

Add required libraries

The installation instructions are similar for all databases. Note that the JDBC driver version needs to be supported by installed database. Additional application properties may be required to be configured based on database version.

Oracle:

Copy “ojdbc-[version].jar” to “/opt/tomcat/lib” folder, so that the Oracle DB connector is on classpath. You can get the required JAR here:

https://mvnrepository.com/artifact/com.oracle.database.jdbc/ojdbc8

MySQL:

Copy “mysql-connector-java-[version].jar” to “/opt/tomcat/lib” folder, so that the MySQL DB connector is on classpath. You can get the required JAR here:

https://mvnrepository.com/artifact/mysql/mysql-connector-java

PostgreSQL:

Copy “mysql-connector-java-[version].jar” to “/opt/tomcat/lib” folder, so that the MySQL DB connector is on classpath. You can get the required JAR here:

https://mvnrepository.com/artifact/org.postgresql/postgresql

Other databases

Find the JDBC client driver for the database and install it using similar steps as the steps above.

Fix address configurations on Tomcat

Edit “/opt/tomcat/conf/server.xml” so that the HTTP connector has the correct IP address:

<Connector port="8080" protocol="HTTP/1.1" address="10.x.x.x" connectionTimeout="20000" redirectPort="8443" />

Create database schema - MySQL

Create a new database or reuse an existing PowerAuth database.
Run the create_schema.sql script to create tables.
Run the initial_data.sql script to load initial data.

For more details see document Database Table Structure.

Create database schema - Oracle

Create a new database or reuse an existing PowerAuth database.
Run the create_schema.sql script to create tables.
Run the initial_data.sql script to load initial data.

For more details see document Database Table Structure.

Create database schema - PostgreSQL

Create a new database or reuse an existing PowerAuth database.
Run the create_schema.sql script to create tables.
Run the initial_data.sql script to load initial data.

For more details see document Database Table Structure.

Update application configurations

Copy XML files described below to “/opt/tomcat/conf/Catalina/localhost”. Then, update configurations in the files to reflect expected values. Make sure to use absolute URLs, not references to localhost, for example:

<Parameter name="powerauth.dataAdapter.service.url" value="http://10.x.x.x:8080/powerauth-data-adapter"/>

<Parameter name="powerauth.nextstep.service.url" value="http://10.x.x.x:8080/powerauth-nextstep"/>

Note that the JDBC settings differ based on used database vendor and JDBC driver requirements.

Copy applications

Create war artifacts using steps described in Compilation, Packaging and Deployment and copy them into /opt/tomcat/webapps.

Note that the Data Adapter project is available in a separate repository Web Flow customization project.

The following war files are required for complete functionality including PowerAuth:

powerauth-admin.war
powerauth-data-adapter.war
powerauth-java-server.war
powerauth-nextstep.war
powerauth-push-server.war
powerauth-webflow-client.war
powerauth-webflow.war

The following war files are optional:

powerauth-tpp-engine.war

Configure Web Flow

Web Flow needs to be configured before starting. See chapter Web Flow Configuration.

Starting Tomcat

Start Tomcat service as the “tomcat” user:

$ sudo -u tomcat sh /opt/tomcat/bin/catalina.sh start

Launching Tomcat in debug mode

Start Tomcat with following command:

$ JPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=9002,server=y,suspend=n" sh /opt/tomcat/bin/catalina.sh jpda start

Observing Tomcat logs

To observe tomcat logs interactively, use following command:

$ tail -f -n200 /opt/tomcat/logs/catalina.out
