Hey @TanawatTor

What you need to focus on here is;
The slave I/O thread stops because master and slave have equal MySQL server UUIDs

To resolve this you should follow these steps;

Remove the file; sudo rm /var/lib/mysql/auto.cnf
Restart mysqld; service mysql restart

This needs to be done on only one of your instances.

HTH,

Andrew
