Prerequisites

Due to the multitude of Java implementations you might want to use, this cookbook does not attempt to address the installation of a JRE/JDK. Please make sure that Java has been configured on the machine prior to the application any resources or recipes shipped in this cookbook.

Usage

Simply include the recipe where you want Tomcat installed.

Due to the ways that some system init scripts call the configuration, you may wish to set the java options to include JAVA_OPTS. As an example for a java app server role:

name "java-app-server"
run_list("recipe[tomcat]")
override_attributes(
  'tomcat' => {
    'java_options' => "${JAVA_OPTS} -Xmx128M -Djava.awt.headless=true"
  }
)

Running Multiple Instances

To run multiple instances of Tomcat, populate the instances attribute, which is a dictionary of instance name => array of attributes. Most of the same attributes that can be used globally for the tomcat cookbook can also be set per-instance - see resources/instance.rb for details.

If they are not set for a particular instance, the base, home, config_dir, log_dir, work_dir, context_dir, and webapp_dir attributes are created by modifying the global values to use the instance name. For example, under Tomcat 7, with home /usr/share/tomcat7, home for instance "instance1" would be set to /usr/share/tomcat7-instance1. The port attributes - port, proxy_port, ssl_port, ssl_proxy_port, ajp_port, and shutdown_port - are not inherited and must be set per-instance. Other attributes that are not set are inherited unmodified from the global attributes. Each instance must define shutdown_port, and at least one of port, ssl_port or ajp_port.

If you only want to run specific instances and not the "base" tomcat instances, you can set run_base_instance to false.

Here is an example partial role:

...
"override_attributes": {
  "tomcat": {
    "run_base_instance": false,
    "instances": {
      "instance1": {
        "port": 8081,
        "shutdown_port": 8006
      },
      "lookup": {
        "port": 8082,
        "shutdown_port": 8007,
        "java_options": "-Xms1G -Xmx2G"
      }
    },
    ...
  }
  ...
}

Managing Tomcat Users

The recipe tomcat::users included in this cookbook is used for managing Tomcat users. The recipe adds users and roles to the tomcat-users.xml conf file.

Users are defined by creating a tomcat_users data bag and placing Encrypted Data Bag Items in that data bag. Each encrypted data bag item requires an 'id', 'password', and a 'roles' field. The data bag key is retrieved from the default location /etc/chef/encrypted_data_bag_secret.

{
  "id": "reset",
  "password": "supersecret",
  "roles": [
    "manager",
    "admin"
  ]
}

If you are a Chef Solo user the data bag items are not required to be encrypted and should not be.
