Chapter 9. The Piranha Web Interface — Features and Configuration

The Piranha Web Interface provides a structured approach to creating the necessary configuration file for a Piranha cluster. This chapter describes the basic operation of the Piranha Web Interface.

Recommendations

Red Hat recommends that the Piranha Web Interface be used for any configuration file changes. The configuration file must follow strict formatting rules; otherwise, the software may experience failures. Using the Piranha Web Interface is the best method of preventing these kinds of problems.

Once a configuration file has been created or updated, the administrator must be sure to copy this file (usually via rcp or scp) to all nodes in the cluster. All nodes must use identical configuration files. Mismatched files are one of the most common cause of cluster problems.
