[Pacemaker] Apace HA

[emmanuel segura]

if you configured apache to bind to the floating ip address configurared in
your cluster, you need to use colocation constrain or a group, because if
you have ip address in one node and apache try to start on a node without
the ip address, apache fails to bind the

colocation ipapache inf: Apache Cluster_Server
order ipapache inf: Cluster_Server Apache

using group

group grp_webserver Cluster_Server Apache


for mo re information you can use the clusterlabs DOCS
