[rabbitmq-discuss] RabbitMQ -- communicate between 3 different machines?

Mon Jul 18 02:07:46 BST 2011

Hi Alvaro,

Thank you for the link and your book recommendation.

Just so that I get things straight, if I install RabbitMQ on 2 different
IPs -- say, {192.168.0.1, 192.168.0.2} -- will both of these be
considered DIFFERENT, independent RabbitMQ servers?
Meaning, each server will carry on its own tasks, messages etc?

Thanks,
Shalom.

Hi Shalom,

You can read the guide here: http://www.rabbitmq.com/pacemaker.html

Not that I like to do self advertisement, but you can also read our book
about RabbitMQ that discusses clustering too: http://bitly.com/rabbitmq

Cheers,

Alvaro
