vi /etc/mysql/my.cnf
---
server-id = 2

root@Omegha-bcp:~#sudo
/etc/init.d/mysql restart
5. Transfer backup file from the Master to Slave server
root@Omegha-bcp:~#scp -i
~/.ssh/pub-key.pem ubuntu@xx.xx.xx.xx:dbdump.db .
6. Import data
root@Omegha-bcp:~#mysql
-uroot -p*** < dbdump.db
7. Point to master
mysql> change master
to master_host='xx.xx.xx.xx', master_user='repl', master_password='****',
master_log_file='mysql-bin.000001', master_log_pos=330;
mysql> start slave;
mysql> show slave
