Installation guide

Because of its efficiency and ease-of-use, administrators of LVS should use firewall marks instead of
persistence whenever possible for grouping connections. However, you should still add persistence
to the virtual servers in conjunction with firewall marks to ensure the clients are reconnected to the
same server for an adequate period of time.
1.9. Clust er Administ rat ion T ools
Red Hat Cluster Suite provides a variety of tools to configure and manage your Red Hat Cluster. This
section provides an overview of the administration tools available with Red Hat Cluster Suite:
Section 1.9.1, “ Conga”
Section 1.9.2, “ Cluster Administration GUI”
Section 1.9.3, “ Command Line Administration Tools”
1.9.1. Conga
Co ng 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 D eployment 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 Co ng 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.
To administer a cluster or storage, an administrator adds (or registers) a cluster or a computer to a
lu ci server. When a cluster or a computer is registered with lu ci, the FQDN hostname or IP address
of each computer is stored in a lu ci database.
