After i follow the Howto mysql clustrering (not include load balacing yet) i type "show" in management node. The problem is the mysqld(API) show "not connected , accepting conect from any host". Before this, everything seem ok( including all test of mysql table), but after i restart the pc and restart the cluster, the mysqld api just wont re-connect on one of the sql node. The other sql node seem ok and connected.
The sql node connected, but at the bottom part mysql (API) shows "not connected , accepting connection from any host". Because it connected so there were no error log. Just the mysql (API ) not connected. I realised when API not connected, there will no data exchange for tht node.
