Packages

Currently this is built into Fedora, RHEL and its clones and Debian and itsderivates.

Quick Start

Authenticate cluster nodes
Set the same password for the hacluster user on all nodes.
```
# passwd hacluster
```
To authenticate the nodes, run the following command on one of the nodes(replacing node1, node2, node3 with a list of nodes in your future cluster).Specify all your cluster nodes in the command. Make sure pcsd is running onall nodes.
```
# pcs host auth node1 node2 node3 -u hacluster
```
Create a cluster
To create a cluster run the following command on one node (replacingcluster_name with a name of your cluster and node1, node2, node3 with a listof nodes in the cluster). --start and --enable will start your clusterand configure the nodes to start the cluster on boot respectively.
```
# pcs cluster setup cluster_name node1 node2 node3 --start --enable
```
Check the cluster status
After a few moments the cluster should startup and you can get the status ofthe cluster.
```
# pcs status
```
Add cluster resources
After this you can add stonith agents and resources:
```
# pcs -h stonith create
```
and
```
# pcs -h resource create
```

Accessing the Web UI

Apart from command line interface you can use web user interface to view andconfigure your cluster. To access the web UI open a browser to the followingURL (replace nodename with an address of your node):
