2. Conga
Conga is an integrated set of software components that provides centralized configuration and
management of Red Hat clusters and storage. Conga provides the following major features:
• One Web interface for managing cluster and storage
• Automated Deployment of Cluster Data and Supporting Packages
• Easy Integration with Existing Clusters
• No Need to Re-Authenticate
• Integration of Cluster Status and Logs
• Fine-Grained Control over User Permissions
The primary components in Conga are luci and ricci, which are separately installable. luci is a
server that runs on one computer and communicates with multiple clusters and computers via
ricci. ricci is an agent that runs on each computer (either a cluster member or a standalone
computer) managed by Conga.
luci is accessible through a Web browser and provides three major functions that are
accessible through the following tabs:
• homebase — Provides tools for adding and deleting computers, adding and deleting users,
and configuring user privileges. Only a system administrator is allowed to access this tab.
• cluster — Provides tools for creating and configuring clusters. Each instance of luci lists
clusters that have been set up with that luci. A system administrator can administer all
clusters listed on this tab. Other users can administer only clusters that the user has
permission to manage (granted by an administrator).
• storage — Provides tools for remote administration of storage. With the tools on this tab, you
can manage storage on computers whether they belong to a cluster or not.
