2.9 Configure the HA Cluster
There are multiple methods to configure the HA cluster, such as using command line, directly
editing configuration files, and using a GUI. Configuring an HA cluster occurs on a single node
and is then pushed to the remiaining nodes in the cluster.
2.9.1 Create an HA Cluster
Perform the following steps to create the HA cluster with CCS command line:
1. Specify your password for ricci with command:
passwd ricci
2. Start the following services:
service ricci start
service rgmanager start
3. Create an HA cluster.
Create the HA cluster with the following command:
ccs -h host --createcluster clustername
Host is the hostname of the node where the “cluster.conf” file will be created.
Clustername can be defined by the user.
For example:
ccs –h HA02.SH --createcluster mycluster
The system will ask for the password that you have defined for “ricci” at step 1.
4. Add nodes to the cluster.
Configure the nodes that the cluster contains by running the following command:
ccs -h host --addnode node
For example:
“ccs –h HA02.SH --addnode HA02.SH”
“ccs –h HA02.SH --addnode HA01.SH”
