Server Farm setup
In this section we are going to configure the server farm. For server
farm I understard the logical configuration of the machines, or how
to group them to build cluster. So, a cluster is a group of machines,
used to server resources, and the server farm is all the clusters
configured.
The configuration directive for this feature is serverfarm
Under this tag, you can configure the clusters and the servers that build
them. Inside this tag, you have to configure, at least, one cluster, with
at least one host inside of them.
The configuration parameters for this tag are:
| Option |
Description |
| cluster |
This is the configuration directive. Under this, you can
configure the hosts that belongs to this cluster.
Configuration options
- name: This is the name of the cluster.
Now, under this configuration directive, you add the hosts
that belongs to this cluster. To do this, you use the
server directive:
Server
- host: This is the name of the host that belongs to
this cluster. You can specify their name in
the two common ways; dotted notation, or
by name.
- port: The port where the service is running
- weight: This is the relative weight that has this
server in the cluster. For example, if we
configure a cluster with three servers,
and their weights are 25, 25 and 50, this
means that the 25% of the requests go to
the first server, 25% of them to the
another server, and the rest to the last
one.

ServerFarm Sample
<serverfarm>
<cluster name="cluster1">
<server host="192.168.0.1" port="80" weight="50" />
<server host="192.168.0.2" port="8080" weight="50" />
</cluster>
<cluster name="cluster2">
<server host="192.168.0.1" port="8080" weight="100" />
</cluster>
</serverfarm>
