NOTE: If you have used the wizard previously to configure a cfengine master server and rerun it to reconfigure the master server, stop the currently running configuration first. For example, use the following command to stop the running cfservd: /sbin/init.d/cfservd stop

If you have cfagent in cron or are using cfexed, disable them so they do not run while the wizard reconfigures the system.

Configuring a single node in a Serviceguard cluster as a master server is not a highly available configuration and is not recommended. The default configuration to create for a cluster is to create a package for cfengine’s cfservd. (To rerun the wizard in a Serviceguard cluster and change your configuration from one that is highly available to one that is not, halt the existing csync package (use cmhaltpkg) and delete it before running the wizard.)

2.3.1.1 Using the Wizard to Configure a Standalone Synchronization Server

To configure a synchronization server for a standalone system, run the csync_wizard(1) on the standalone system you wish to configure as the master synchronization server:

#/opt/dsau/sbin/csync_wizard

The wizard displays the following introductory screen:

Querying the system local_hostname for current status, one moment...

This Configuration Synchronization Wizard (csync_wizard) helps you set

up the Configuration Engine (cfengine) environment. Cfengine is a powerful tool for performing policy-based management for groups of systems and cluster environments.

csync_wizard is a client/server based utility. With csync_wizard, the user can configure a standalone system or Serviceguard cluster as the cfengine “master”. The master contains the configuration description and configuration files that will be used by all the clients. Clients copy the configuration description from the master and apply it to themselves.

The configuration description supports a rich set of management actions such as copying configuration files from the master to the client, performing edits to files, checking file ownerships, permissions, and checksums, executing shell commands, checking for processes, etc.

For a detailed description of the cfengine management actions, please refer to the cfengine man page.

The csync wizard helps you set up this system as a cfengine master, add or remove cfengine-managed clients, and perform the required security setup.
