Changing clustering configuration

Clusters > Changing clustering configuration

Clustering is usually configured when you install the proxy. You can, however, configure clustering afterward, or at any time, in Content Gateway Manager.

1.	In Content Gateway Manager, go to the Configure > My Proxy > Basic > Clustering tab.

2.	In the Cluster Type area, select the clustering mode:

Select Management Clustering to include this proxy in a cluster.

Select Single Node if this node is not part of a cluster.

3.	In the Cluster Interface area, enter the name of the network interface. This is the interface used by Content Gateway to communicate with other nodes in the cluster, for example: eth0.

Node configuration information is multicast, in plain text, to other Content Gateway nodes on the same subnet. Therefore, Websense recommends that clients be located on a separate subnet from Content Gateway nodes (multicast communications for clustering are not routed).

On V-Series appliances, P1 (eth0) is the recommended interface. However, you may also use P2 (eth1) if you want to isolate cluster management traffic.

4.	In the Cluster Multicast Group Address area, enter the multicast group address that all members of the cluster share.

If you are using SSL Manager and want SSL configuration information to propagate around the cluster, enter the IP address of the SSL Manager Configuration Server. In a cluster, SSL configuration information is managed via a separate mechanism. You must be familiar with the mechanism to effectively use this feature. See SSL Manager clustering.

6.	Click Apply.

7.	Click Restart on Configure > My Proxy > Basic > General.


	Important Content Gateway does not apply the clustering mode change to all of the nodes in the cluster. You must change the clustering mode on each node individually.
