Your question is ambiguous. Can you please invest a bit more effort to explain what you have installed and plan to do?
Generally, you cannot use a Linux cluster as a substitute for running Oracle RAC. Oracle RAC provides the required software and infrastructure to be able to run a single database on multiple nodes. It requires to install RAC on at least 2 nodes and special shared storage devices providing block level access. The later is typically iSCSI or Infinitiband or Fiber cable, or Oracle Direct NFS.

thanks my friend .
you answered my question as you mentioned we need at least two node for running cluster.
but I have another question can I add node to rac one node database?

You can install cluster on one node, the with your business grows, you and extend your cluster to other nodes, it's quite flexible. It makes economic sense.
