The following post contains a documentation of the tools that liferay offers for portal administration.
The administrative side of liferay can be divided into two major categories.
Liferay Portal -
- Control Panel
- Site Administration
We shall look at both these in detail in the following post.
The Control Panel contains the core tools for managing users, roles, Marketplace plugins, portal settings, and portal-wide settings.
The Control Panel can be further divided as follows -
Users are individuals who perform tasks using the portal. The following are some of the actions that can be taken on a user.
- Edit details about a user.
- Define which roles have permissions to edit the user.
- Manage the public and private pages of the user’s personal site.
- Impersonate the user.
- Deactivate the user’s account.
Organizations in Liferay represent real life organizations. They can be hierarchal to unlimited levels and can be associated with Roles to manage permissions. They can also have organizational sites. The following actions can be taken on an organization –
- Edit or delete an organization.
- Manage the pages of an organization.
- Add new or assign existing users to the organization.
- Add sub-organizations.
- Assign users to organization roles.
- Add a location which is an organization that cannot have children.
User Groups are a specific groupings of users. User groups provide a way to group users independently of the organizations to which they belong. Administrators can define a user group and assign the user group as a member of a site to make all of its users members automatically. User groups can be associated with User Group Sites which can only be accessed by the members of the User Group.
Roles are groupings of users that share a particular function within the portal, according to a particular scope. Administrators can add roles which can be granted permissions to various functions within portlet applications.
Roles combine users with permissions. All permissions in Liferay must be assigned through Roles. Roles can be scoped by – Portal, Organization or Site.
Portal scoped roles are known as regular roles.
By default there are 4 regular roles –
- Administrator – Users with administrative privileges
- User – Regular user
- Power User – User-defined
- Guest (Visitor) – All non-logged in users.
Site / Organization Roles
There are three Site / Organization scoped roles
- Owner – Owners are super users of their site or organization and can assign site roles, including administrator roles to users.
- Administrator – Admins are super users of their site or organization but cannot make other users into site / organization administrators.
- Member / User – All users who belong to a site / organization have this role in that site or organization.
Sites are a set of pages that display content and provide access to specific applications. Sites can have members, which are given exclusive access to specific pages or content. The actions on sites are handled through Site Administration. There are two sets of site pages: public pages (Build a website for the public to see) and private pages (Members of the site to interact and collaborate).
Any user can join these sites from the My Sites portlet.
To join these sites, users must be added by a site administrator. Users can submit requests to join restricted sites through the My Sites portlet.
Similar to restricted sites but they don’t appear in the My Sites portlet. Thus users can’t submit requests to join Private sites; they must be added by a site administrator.
Liferay allows users to install pre-build apps.
Settings is where most of the global portal settings are including names, authentication, default user associations, and mail host names.
Custom Fields allow end users to extend the default data entries. They are also available as a service so that they can be used from custom portlets.
Liferay provides both a Workflow Framework and Workflow Plugin. The Workflow Framework is part of Liferay Portal and is the internal API that allows the built-in portlets and custom portlets to transition through the Workflow process. In order to use Liferay’s Workflow, you will need to install a plugin that provides a workflow engine. Liferay provides the Kaleo Workflow Engine.
Server Administration settings control logs, caching, search indexing, and other advanced features. Advanced administrators can monitor system performance, alter detailed server settings, reindex searches and modify caching.
This option contains configuration for individual sites, including their content, pages, documents, themes, and various assets that belong to that site.
All pages in Liferay Portal belong to Sites. By default individual users have their own personal Sites, which have pages. Liferay allows customization of page based on the look and feel, and addition of portlets.
These pages are accessible to anyone, including those not logged into the portal.
These pages are accessible only to members of the Site.
Any content type in Liferay is considered an asset. Developers can create new content types. Vocabularies and Categories can help
