3. Create DB. This repository contains a simple datatabase schema.

Create a database with the database name and user / password credentials you defined in the previous resource.

4. Generate WAR file. build your grails app with ./gradlew assemble.

5. Copy your app to tomcat webapps

cp app/build/libs/app-0.1.war apache-tomcat-8.5.2.3/webapp/app-0.1.war

6. Start tomcat

apache-tomcat-8.5.2.3/bin/$ ./startup.sh

Your grails application should populate the database with three books.
