Hi,

I have a HA cluster setup with Apache nodes using Heartbeat. It works like a charm. I have it setup in combination with ldirectord for load balancing. I started out using a tutorial from http://www.howtoforge.com and completed the HA by setting up master-master replication for the MySQL databases.

Kind regards,

Eric

Heartbeat is being deprecated by corosync. In either case they should be used as a component of Pacemaker as linked above.

You might be right, but I'm a fan of:

Code:

If it works; don't break it!

and the way I have it set up it does exactly what we need.

Thanks for the heads up though.

Kind regards,

Eric

You can check out the following web pages that elaborate the
problems of conventional HA solutions like VCS and block level
replication solutions like DRBD. The web site also offer
new solutions for HA and many other areas.
