Problem with:

I followed the tutorial as above. The problem I am having is when I enter "mysql -u root -p -e “SHOW STATUS LIKE ‘wsrep_cluster_size’;” it shows a value 0f ‘0’, Zero for the wsrep_cluster_size. Also when I enter: "mysql -u root -p -e “SHOW STATUS LIKE ‘wsrep%’;” ir shows “wsrep_connected = OFF, wsrep_cluster_status = Disconnected and wsrep_ready = OFF”

How can I get connected and turn the OFFs to ONs?
