liferay #5

Supports: precise
Add to new model


Installs Liferay Portal, a Java-based, open source enterprise portal. Liferay provides a powerful Web CMS, collaboration, and enterprise integration functionality with a lightweight footprint and flexible development model. See for details.

Liferay Portal

is an
open source enterprise web platform for building business solutions that deliver
immediate results and long-term value. Liferay Portal started out as a personal
development project in 2000 and was open sourced in 2001.

To get started, check out the project's community homepage at!

This Juju Charm will install the pre-built Liferay Portal bundle, including
Apache Tomcat. To use this Charm once it is installed, use your web browser and
visit http://:8080 where is the hostname or IP address of the Juju
service node running Liferay (discoverable via juju status).

Installing the Liferay Charm

This Liferay Charm has a dependency on the MySQL charm. To create a Juju
environment and get started using Liferay, run the following:

$ juju bootstrap
$ juju deploy mysql
$ juju deploy liferay
$ juju add-relation liferay mysql

This will create your Juju environment, deploy MySQL and Liferay, and connect
them together via add-relation. For more information on Juju commands, visit
The Juju Site.

After a while, Liferay will be up and running on the machine instance that
was created for it. You can discover the network address of Liferay by running

$juju status

Look for the public-address setting for the Liferay service, and access
Liferay using http://hostname_or_ip:8080. Note that on the first Liferay
page you get, the MySQL configuration values are already set to the values
necessary to connect Liferay to MySQL and should not be changed. Other settings
can be changed as needed, such as the screen name or password of the default
user, the name of the portal, and so on.

If something goes wrong, you can view the log files using

$juju debug-log --replay

Charm Service Configuration Options

This charm supports the following configuration options:

  • http-port - The port on which Liferay will listen for HTTP connections (Default:
  • java-opts - Option string to pass to the Java VM command line during startup.
    See the config.yaml file for the default settings. This option can be used to,
    for example, set the default Java VM heap size, or tune garbage collection.

To configure Liferay at deploy time, first create a yaml-formatted text file
specifying the values you wish to use.

  http-port: 5050
  java-opts: -Dfile.encoding=UTF8 -Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false -Duser.timezone=GMT -Xmx2g -XX:MaxPermSize=512m

Then issue the deploy command, specifying the file: juju deploy --config myconfig.yaml liferay

To modify service configuration after the charm has been deployed, use the
juju set command. For example: juju set liferay http-port=4321

Upgrading the Liferay Charm

When a new version of the Liferay Charm is available, you can upgrade to it
using the following command:

$ juju upgrade-charm liferay

This command will upgrade to the latest release of the Liferay charm. If the
charm also contains support for a newer version of Liferay, the Liferay service
associated with the charm will also be upgraded, by downloading the new version
of Liferay, migrating configuration from the previous version of Liferay,
and starting the new Liferay version in place of the old Liferay version. For
more information on how Liferay upgrades itself, see the
Upgrading Liferay
chapter in Liferay's official documentation.

Currently, the charm will copy your files and your
Liferay data directory, but not modify their contents. Future releases of
this charm will add additional logic to deal with future Liferay upgrade

Stopping the Liferay Charm

The Liferay Charm supports all of the lifecycle operations of Juju, so
adding/removing relations, and starting/stopping services will cause Liferay
to start and/or stop as needed. To stop the Liferay service, use the
juju destroy-service liferay command.

Source Code

Liferay's main source code resides in two repositories:
liferay-portal and
liferay-plugins. Liferay has
additional repositories for the following:

Liferay Portal releases are built from the liferay-portal repository and
include select plugins from the liferay-plugins repository. You can build
