    bind-address = Your-Master-IP
  4. Next, uncomment the following line –

    log_bin = /var/log/mysql/mysql-bin.log log_bin_index =/var/log/mysql/mysql-bin.log.index relay_log = /var/log/mysql/mysql-relay-bin relay_log_index = /var/log/mysql/mysql-relay-bin.index
  6. Save and close the file then restart the MySQL service to apply the changes –
    systemctl restart mysql
