Tomcat Puppet module

Build Status

Manages Tomcat configuration.

This module is provided by Camptocamp.

This module will install tomcat, either using you system's package manager or from a compressed archive available on one of the tomcat-mirrors.

This is done by including the tomcat class for a package based setup or declaring the class with the parameter sources => true for a source based setup.

Instances

You'll then be able to define one or more tomcat instances, where you can drop your webapps in the ".war" format. This is done with the tomcat::instance definition.

The idea is to have several independent tomcats running on the same host, each of which can be restarted and managed independently. If one of them happens to crash, it won't affect the other instances. The drawback is that each tomcat instance starts it's own JVM, which consumes memory.

This is implemented by having a shared $CATALINA_HOME, and each instance having it's own $CATALINA_BASE. More details are found in this document: http://tomcat.apache.org/tomcat-6.0-doc/RUNNING.txt

Logging

To offer more flexibility and avoid having to restart tomcat each time catalina.out is rotated, tomcat is configured to send it's log messages to log4j. By default log4j is configured to send all log messages from all instances to /var/log/tomcat/tomcat.log.

This can easily be overridden on an instance base by creating a custom log4j.properties file and setting the common.loader path to point to it, by editing /srv/tomcat/<name>/conf/catalina.properties.

Dependencies

The Apache puppet module available at http://github.com/camptocamp/puppet-apache is required if you want to make use of Apache integration.

The Archive puppet module available at http://github.com/camptocamp/puppet-archive is required if you want to install tomcat from a compressed archive (it uses archive).

Defaults

By default a new tomcat instance create by a tomcat::instance resource will listen on the following ports:

  • 8080 HTTP
  • 8005 Control
  • 8009 AJP

You should override these defaults by setting attributes server_port, http_port and ajp_port.

Limitations

  • there is no way to automatically manage webapps (\*.war files).
  • the initscript calls catalina.sh instead of using jsvc. This prevents tomcat from listening on ports < 1024.

Examples

Simple standalone instance:

Create a standalone tomcat instance whose HTTP server listen on port 8080:

include tomcat

tomcat::instance {'myapp':
  ensure    => present,
  http_port => '8080',
}

If you want to install a specific tomcat version from a specific mirror:

$tomcat_mirror = 'http://archive.apache.org/dist/tomcat/'
$tomcat_version = '6.0.32'
include tomcat::source

Apache integration

Pre-requisites:

include apache

apache::module {'proxy_ajp':
  ensure  => present,
}

apache::vhost {'www.mycompany.com':
  ensure => present,
}

Create a tomcat instance which is accessible via Apache using AJP on a given virtualhost:

include tomcat

tomcat::instance {'myapp':
  ensure      => present,
  ajp_port    => '8000'
}

apache::proxypass {'myapp':
  ensure   => present,
  location => '/myapp',
  vhost    => 'www.mycompany.com',
  url      => 'ajp://localhost:8000',
}

Multiple instances

If you create multiple Tomcat instances, you must avoid port clash by setting distinct ports for each instance:

include tomcat

tomcat::instance {'tomcat1':
  ensure      => present,
  server_port => '8005',
  http_port   => '8080',
  ajp_port    => '8009',
}

tomcat::instance {'tomcat2':
  ensure      => present,
  server_port => '8006',
  http_port   => '8081',
  ajp_port    => '8010',
}

Create a tomcat instance with custom connectors

First you have to declare you connectors then they are added to the tomcat-instance:

include tomcat

tomcat::connector{'http-8080':
  ensure   => present,
  instance => 'tomcat1',
  protocol => 'HTTP/1.1',
  port     => 8080,
  manage   => true,
}

tomcat::connector{'ajp-8081':
  ensure   => present
  instance => 'tomcat1'
  protocol => 'AJP/1.3',
  port     => 8081,
  manage   => true,
}

tomcat::instance {'tomcat1':
  ensure    => present,
  group     => 'tomcat-admin',
  manage    => true,
  connector => ['http-8080','ajp-8081'],
}
