For replication to work you must enable binary logging on the master. If binary logging is not enabled, replication will not be possible as it is the binary log that is used to exchange data between the master and slaves.

Each server within a replication group must be configured with a unique server-id value. The server ID is used to identify individual servers within the group, and must be positive integer between 1 and (2³²)–1. How you organize and select the numbers is entirely up to you.

To configure the binary log and server ID options, you will need to shut down your MySQL server and edit the configuration of the my.cnf or my.ini file.

You will need to add the following options to the configuration file within the [mysqld] section. If these options already exist, but are commented out, uncomment the options and alter them according to your needs. For example, to enable binary logging, using a log file name prefix of mysql-bin, and setting a server ID of 1:

[mysqld]
log-bin=mysql-bin
server-id=1
