##Overview

The tomcat module enables you to install, deploy, and configure Tomcat web services.

##Module Description

Tomcat is a Java web service provider. The Puppet Labs module gives you a way to install multiple versions of Tomcat, as well as multiple copies of a version, and deploy web apps to it. The tomcat module also manages the Tomcat configuration file with Puppet.

##Setup

NOTE: You must have Java installed in order to use this module. The version of Java needed will depend on the version of Tomcat you are installing. Older versions of Tomcat require >=java6, while the latest version of Tomcat needs >=java7.

###Beginning with tomcat

The simplest way to get Tomcat up and running with the tomcat module is to install the Tomcat package from EPEL,

class { 'tomcat': }
class { 'epel': }->
tomcat::instance{ 'default':
  install_from_source => false,
  package_name        => 'tomcat',
}->

and then start the service.

tomcat::service { 'default':
  use_jsvc     => false,
  use_init     => true,
  service_name => 'tomcat',
}

##Usage

###I want to install Tomcat from a specific source.

To download Tomcat from a specific source and then start the service,

class { 'tomcat': }
class { 'java': }
tomcat::instance { 'test':
  source_url => 'http://mirror.nexcess.net/apache/tomcat/tomcat-8/v8.0.8/bin/apache-tomcat-8.0.8.tar.gz'
}->
tomcat::service { 'default': }

###I want to run multiple copies of Tomcat on a single node.

class { 'tomcat': }
class { 'java': }

tomcat::instance { 'tomcat8':
  catalina_base => '/opt/apache-tomcat/tomcat8',
  source_url    => 'http://mirror.nexcess.net/apache/tomcat/tomcat-8/v8.0.8/bin/apache-tomcat-8.0.8.tar.gz'
}->
tomcat::service { 'default':
  catalina_base => '/opt/apache-tomcat/tomcat8',
}

tomcat::instance { 'tomcat6':
  source_url    => 'http://apache.mirror.quintex.com/tomcat/tomcat-6/v6.0.41/bin/apache-tomcat-6.0.41.tar.gz',
  catalina_base => '/opt/apache-tomcat/tomcat6',
}->
tomcat::config::server { 'tomcat6':
  catalina_base => '/opt/apache-tomcat/tomcat6',
  port          => '8105',
}->
tomcat::config::server::connector { 'tomcat6-http':
  catalina_base         => '/opt/apache-tomcat/tomcat6',
  port                  => '8180',
  protocol              => 'HTTP/1.1',
  additional_attributes => {
    'redirectPort' => '8543'
  },
}->
tomcat::config::server::connector { 'tomcat6-ajp':
  catalina_base         => '/opt/apache-tomcat/tomcat6',
  port                  => '8109',
  protocol              => 'AJP/1.3',
  additional_attributes => {
    'redirectPort' => '8543'
  },
}->
tomcat::service { 'tomcat6':
  catalina_base => '/opt/apache-tomcat/tomcat6'

###I want to deploy WAR files.

tomcat::war { 'sample.war':
        catalina_base => '/opt/apache-tomcat/tomcat8',
        war_source => '/opt/apache-tomcat/tomcat8/webapps/docs/appdev/sample/sample.war',
      }

The war_source can be a local file, puppet:/// file, http, or ftp.

##Development

###Contributing

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

You can read the complete module contribution guide on the Puppet Labs wiki.
