virtual host changes in each nodes config files?

rajeshchande Nov 21, 2006 10:05 AM

Hello,

I am setting up a cluster consisting of atleast 2 nodes on solaris. The cluster runs fine in terms of farm deployment.

The applications deployed use virtual host for getting accessed. http://aaa-devl.abc.xyz.com. In accordance the $JBOSS_HOME/server/$NODE1/deploy/jbossweb-tomcat55.sar/server.xml would have following details:
 <Host name="aaa" autoDeploy="false" deployOnStartup="false" deployXML="false">
 <Alias>aaa-devl.abc.xyz.com</Alias>
 <Valve className="org.apache.catalina.valves.FastCommonAccessLogValve"
 prefix="access" suffix=".log" rotatable="false"
 pattern="common" directory="${jboss.server.home.dir}/log/aaa"
 resolveHosts="false" />
 </Host>
My question is, since this is in a cluster, i need to replicate the above configurations on other Nodes (ALL other instances) in a cluster? Any way to just change it at one location and all the instances should read the new changes?

Regards,

Was my question a real tough one? Or no one understood it? OR a real silly one? ;-)

just wondering if can get some inputs on this?

You need to redo the same config on all servers. The server.xml file is not replicated.

Thanks for that.

Although this may be the fact, does not sound a good feature, that each new deployment would ask for restart of all nodes.

One workaround is to load balance across two clusters and bring one cluster down at a time in order to deploy the changes. I've seen a few 24/7 production environments that do this, but it won't work for every architecture.
