I stop Heartbeat on both nodes. And get following error on

2015-08-18 16:50:38 7081 [ERROR] Slave I/O: Fatal error: The slave I/O
thread stops because master and slave have equal MySQL server ids;
these ids must be different for replication to work (or the
--replicate-same-server-id option must be used on slave but this does
not always make sense; please check the manual before using it).
Error_code: 1593

I try to fix it.
