In the last blog which features creating a basic module in Puppet here and here, this is a sample init.pp I’ve created to install, tomcat,mysql,subversion,java1.5 and load a database from a dump file. Notice that JDK is installed while accepting the license by using debconf-utils package. Tested in Ubuntu hardy which is launch from Amazon EC2.

Hope this will help some of my friends in their Puppet configurations.

     file { "/root/db.sql":
         source=> "puppet://$servername/hostmanager/db.sql"
     }

         source=> "puppet://$servername/hostmanager/tomcat5.5"

Let’s start learning more about puppet. 🙂
