Hello Everyone,

I have a working MySQL cluster which is based on 2 nodes.

Now on my 3rd server i want to use it as a Load balancer for the MySQL cluster.

As, i do not have that much experience in load balancing part so i Google for it and i finally made my configuration file.

Kindly take a look at the attached config file.

And please tell me if i am missing some parameters.

Thanks,

usmangt
