1.2. Conga
Co n g a is an integrated set of software components that provides centralized configuration and
management of Red Hat clusters and storage. Co n g a provides the following major features:
One Web interface for managing cluster and storage
Automated Deployment of Cluster D ata 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 Co n g a are lu ci and ricci, which are separately installable. lu ci 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 Co n g a.
lu ci is accessible through a Web browser and provides three major functions that are accessible
through the following tabs:
h o meb ase — 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.
clu st er — Provides tools for creating and configuring clusters. Each instance of lu ci lists
clusters that have been set up with that lu ci. 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).
st o rag e — 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.
