5.3. St art ing ricci
In order to create and distribute cluster configuration files on the nodes of the cluster, the ricci
service must be running on each node. Before starting ricci, you should ensure that you have
configured your system as follows:
1. The IP ports on your cluster nodes should be enabled for ricci. For information on enabling
IP ports on cluster nodes, see Section 2.3.1, “ Enabling IP Ports on Cluster Nodes” .
2. The ricci service is installed on all nodes in the cluster and assigned a ricci password, as
described in Section 2.13, “ Considerations for ricci ” .
After ricci has been installed and configured on each node, start the ricci service on each node:
# servi ce ricci start
Starting ricci: [ OK ]
5.4 . Creat ing and Modifying a Clust er
This section describes how to create, modify, and delete a skeleton cluster configuration with the ccs
command without fencing, failover domains, and HA services. Subsequent sections describe how to
configure those parts of the configuration.
To create a skeleton cluster configuration file, first create and name the cluster and then add the
nodes to the cluster, as in the following procedure:
1. Create a cluster configuration file on one of the nodes in the cluster by executing the ccs
command using the -h parameter to specify the node on which to create the file and the
createcl uster option to specify a name for the cluster:
ccs -h host --createcluster clustername
For example, the following command creates a configuration file on no d e-
0 1. example. co m named mycl uster:
