Upgrading Binlog Router to MaxScale to 1.3

Upgrading Binlog Router to MaxScale to 1.3

This document describes upgrading the Binlog Router module to MaxScale version 1.3.

What's new

The master server details are now provided with a master.ini file located in the binlog directory and it can be changed using a CHANGE MASTER TO command issued via a MySQL connection to MaxScale.

This file, properly filled, is now mandatory and without it the binlog router cannot connect to the master database.

Before starting binlog router after MaxScale 1.3 upgrade, please add relevant information to master.ini, example:

[binlog_configuration]
master_host=127.0.0.1
master_port=3308
master_user=repl
master_password=somepass
filestem=repl-bin

Additionally, the option servers=masterdb in the service definition is no longer required.
