<p class=MsoNormal>I’ve been bashing my head into a wall the past few
days on this.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am trying to setup a Load Balanced MySQL Cluster. I can
get the MySQL NDB Clusters working, but when I try to install the HA Load
Balancers, I can’t get past the step of the shared Virtual IP. I’m
basing my sequence on HowToForge Guide written for Debain (<a
href="http://www.howtoforge.com/loadbalanced_mysql_cluster_debian_p7">http://www.howtoforge.com/loadbalanced_mysql_cluster_debian_p7</a>).
I’ve added my own tweaks and use the appropriate CentOS x64 commands and
configurations.<o:p></o:p></p>

<p class=MsoNormal>I am creating a loopback interface with the following
