imeshd Nov 26, 2013 10:35 PM

I am trying to use mod_cluster and this is my first clustering experience. My apache is working fine and I see It works! page.

but when I try to access http://localhost/mod_cluster-manager I get page not found error.

Jboss AS 6.1.0 final

mod_cluster version mod_cluster-1.2.0

in error_log I see below error

[error] [client 127.0.0.1] File does not exist: C:/Documents and Settings/user/My Documents/Downloads/openlogic-mod_cluster-1.2.0-windows-ia32-bin-1/mod_cluster-1.2.0/httpd-2.2/htdocs/mod_cluster-manager

Here is my httpd.conf file snipt.

Ok at least I was able to view the page. with change <VirtualHost *:80>. Can anyone explain me why and how this happened? whats the relation ship with this tag?
I see the below details now in the http://localhost/mod_cluster_manager page. but still cluster nodes are not showing.

The SetHandler mod_cluster-manager is in a VirtualHost so that is normal you should have accesss to http://localhost:6666/mod_cluster-manager
The nodes need see the advertise messages you probably have a firewall that prevent that. (See http://docs.jboss.org/mod_cluster/1.2.0/html/faq.html).

Hi Jean,
Thanks for the quick revert.
I have switch off the firewall already as I saw ppl were advised to do so. I just want to tell that I did basic Jboss configuration that is I copied the whole jboss distribution to two folders (node_1 and node_2) and start one by one. ( I changed the port to ports-default and ports-01
I start jboss as run.bat -c all
below is the output of the first after I start the second node. This means clustering works fine.

I have add this line in to run.conf file in each jboss node.

imeshd Nov 29, 2013 2:55 AM (in response to jfclere)

Hi Jean,

If I got what you said, I uncomment the "ServerAdvertise on http://127.0.0.1:6666" line. Now the httpd.conf snipt as follows.

    KeepAliveTimeout 300
    MaxKeepAliveRequests 0
    ServerAdvertise on http://127.0.0.1:6666                      <-- uncommented this line.
    AdvertiseFrequency 5
    #AdvertiseSecurityKey secret
    AdvertiseGroup 239.255.100.100:23364
    EnableMCPMReceive

And now the out put of "http://localhost/mod_cluster_manager"

mod_cluster/1.2.0.Final
start of "httpd.conf" configuration
mod_proxy_cluster.c: OK
mod_sharedmem.c: OK
Protocol supported: AJP
mod_advertise.c: OK
Server: TSA-ST-9TK6NX1.sgp-tsd.dsd

end of "httpd.conf" configuration

Check that you have AS6 configured according to http://docs.jboss.org/mod_cluster/1.2.0/html/java.config.html#ModClusterListener
Check that you have mod_cluster bean started in AS6: there should be mod_cluster message while starting the server.
BTW: Why are you using such an old version of AS?

Hi Jean,

When I follow that instructions I get below error.

Hi Jean,

Which jar file?
I already have \server\all\deploy\mod_cluster.sar folder and mod_cluster.jar file is inside.

jfclere Nov 29, 2013 4:14 AM (in response to imeshd)

That is an old version.... that is mod_cluster 1.1.0.Final.
you should remove the mod_cluster.sar folder and replace it by the mod_cluster.sar from http://www.jboss.org/mod_cluster/downloads/1-2-6-Final-bin.html
again why are you using an old version?

Hi Jean,

Sorry,My company wants to use this version. And I can not change it. May be "Old is gold". Hope you will assist me to fix this further.

OK I downloaded the file java bundles from the page you gave and their were 3 folders call demo, JBossWeb-Tomcat, mod_cluster.sar
I simply copied mod_cluster.sar folder to jboss1\server\all\deploy folder.

I have this error now.
