82 Chapter 6: Using Multiple Server Instances
5 Open the jrun_root/lib/security.properties file and add the IP addresses of the other JRun
servers in the cluster to
jrun.trusted.hosts.
6 Open the JMC and create a cluster that contains your server instances.
Note: Do not add the admin JRun server to a cluster.
7 If using failover, perform the following steps in the JMC:
a Open the cluster by clicking the cluster name in the left panel.
b Open the first server instance by clicking its name in the list.
c Open the Macromedia ColdFusion MX application.
d Specify the context path (usually /).
e Select Enable Session Replication.
f In the New Replication Buddy field, enter the names of the other servers in the cluster one-
by-one, and click Add.
g Click Apply.
h Perform these steps for every server instance in the cluster.
8 Run the Web Server Configuration Tool. Choose your website, but instead of choosing a single
server instance, select the cluster. For more information, see “Web server configuration”
on page 59.
9 Store the application’s CFM files in your external web server root directory.
10 Test the application to ensure that load balancing and failover work as expected.
