Mod_cluster can't read status in non-multicast environment

[funa516]

Hi,

I implemented mod_cluster, but frontend httpd cannot read STATUS command from backend jboss.web.

I checked Mod_cluster status page by web browser,
the status is following.

===================================================================
mod_cluster/1.1.x
Auto Refresh show DUMP output show INFO output

Node 127.0.0.1:8009:jboss.web (ajp://127.0.0.1:8009):

60000000,Status: NOTOK,Elected: 0,Read: 0,Transferred: 0,Connected: 0,Load: -1
===================================================================

"Status: NOTOK". And on backend jboss server, executing run.sh -c all, it outputs following error.

========================
04:16:26,188 ERROR [org.jboss.modcluster.mcmp.impl.DefaultMCMPHandler] Error [MEM: MEM: Can't read node: {4}] sending command STATUS to proxy /xxx.xxx.xxx.xxx:6666, configuration will be reset
========================

Httpd proxy port is 6666, and proxyList is xxx.xxx.xxx.xxx:6666 .
How can I repair the httpd and jboss server ?

Apache httpd.conf is,
========= begin httpd.conf ========================
<Location /mod_cluster-manager>
SetHandler mod_cluster-manager
Order deny,allow
Deny from all

</Location>

========= end httpd.conf ========================

JBOSS mod_cluster-jboss-beans.xml file is
$JBOSS_HOME/server/all/deploy/mod_cluster.sar/META-INF/mod_cluster-jboss-beans.xml
========= mod_cluster-jboss-beans.xml ========================
    <!-- Comma separated list of address:port listing the httpd servers

   <!-- <property name="proxyList">${jboss.mod_cluster.proxyList:}</property> -->

    <!-- URL prefix to send with commands to mod_cluster.  Default is no prefix. -->
    <!--property name="proxyURL"></property-->
========= mod_cluster-jboss-beans.xml ========================

Thanks and regards,

It seems you get the node more than once in the mod_cluser table {4} you have 4 nodes?

Try to remove the

ServerAdvertise off
AdvertiseFrequency 5

From the httpd.conf file.

Thank you.

No, I have only a Mod_cluster httpd server and a JBossWeb-Tomcat server.

I don't know why mod_cluster table has 4 nodes.

I removed these, and retried.

However, I got same error messages.

23:55:38,335 ERROR [org.jboss.modcluster.mcmp.impl.DefaultMCMPHandler] Error [MEM: MEM: Can't read node: {4}] sending command

STATUS to proxy /xx.xxx.xxx.xxx:6666, configuration will be reset

Mod_Cluster version is,

  - LB: mod_cluster-1.1.0.CR1

  - AP: jboss-6.0.0.20100216-M2

And I checked these in Amazon EC2, I opened almost all network ports, but it cannot get status.

Any ideas ?

Set httpd loglevel to debug and post the log (error_log) to the forum.

[funa516]

Thank you.

I set loglevel debug, and  watched error_log.

I noticed following error.

  [Tue May 11 03:39:54 2010] [error] (111)Connection refused: proxy: ajp: attempt to connect to 127.0.0.1:8009 (127.0.0.1) failed

ajp couldn't connect 127.0.0.1.

I checket netstat, 8009 port isn't opened.

On the mod_cluster server, I just installed jboss httpd server.

Is it neccessary to install jboss tomcat into the mod_cluster (LoadBalancer) server ?

I checked following page, and configured it.

On the same server, I didn't install jboss AS.

ajp couldn't connect 127.0.0.1.

I checket netstat, 8009 port isn't opened.

It seems jboss is running on another box and the AJP connector use the address localhost that can't work.

> It seems jboss is running on another box and the AJP connector use the address localhost that can't work.

Thanks.

But I still don't understand the meaning.

How can I make it ?

By the way,

I configured httpd and Java side in a box. ( in one node)

After that, I checked mod_cluster-manager page, I got following messages.

--------------------------

mod_cluster/1.1.x

Auto Refresh show DUMP output show INFO output

Node 127.0.0.1:8009:jboss.web (ajp://127.0.0.1:8009):

Enable Contexts Disable Contexts
Balancer: mycluster,Domain: ,Flushpackets: Off,Flushwait: 10000,Ping: 10000000,Smax: 26,Ttl: 60000000,Status: OK,Elected: 0,Read: 0,Transferred: 0,Connected: 0,Load: 100

-----------------------------

Like this, the status became OK.

But this is in a box, and I'd like to configure httpd and ap which are separated.

Thanks and regards,

Kenji

When you start the JBoss instances, use the -b switch to cause them to bind their sockets to a different address than localhost/127.0.0.1. If you don't use the -b switch, by default all sockets are bound to localhost. The httpd server running on a different machine obviously can't communicate with such a socket.

Thank you.

I run following cmd on backend java-side server.

run.sh -c all -b xxx.xxx.xxx.xxx

And I got following information on mod-manager page.

--------

mod_cluster/1.1.x

--------

It seems that it could get the status.

However, I tried to access http://<mod_cluster ip>/ ,

mod_cluster doesn't foward it to backend jbossweb.

I just saw "It works!" apache httpd page.

I'd like mod_cluster to foward it.

Is it necessary to add ProxyPass into httpd.conf ?

Otherwise, how can I config it ?

httpd.conf is following

---------- /opt/jboss/httpd/httpd/conf/httpd.conf --------

<Location /mod_cluster-manager>
SetHandler mod_cluster-manager
Order deny,allow

Allow from all
</Location>

# ProxyPass /balancer-manager !

<VirtualHost xxx.xxx.xxx.xxx:6666>
   <Directory />
      Order deny,allow
      Deny from all
      Allow from xx.xxx.xxx.
      Allow from xx.xxx.xxx.
   </Directory>

KeepAliveTimeout 60
MaxKeepAliveRequests 0

ManagerBalancerName mycluster
# ServerAdvertise off
# AdvertiseFrequency 2

</VirtualHost>

Check excludedContexts. It seems you don't have any context deployed or all are in the excludedContexts list.

[funa516]

> Check #excludedContexts. It seems you don't have any context deployed or all are in the excludedContexts list.

Thanks.

I add "all" in mod_cluster-jboss-beans.xml, like this.

------

<property name="excludedContexts">${jboss.mod_cluster.excludedContexts:ROOT,admin-console,invoker,jbossws,jmx-console,juddi,web-console,all}</property>

------

And I can access jbosswd and juddi pages .etc.

But how can I access them from mod_cluster to them.

For example,

  - JBOSS WS page url : http://<JBOSS AP IP>:8080/jbossws  ( Access succeeded )

  - httpd mod_cluster url : ???  ( http://<httpd mod_cluster IP>/jbossws ?? )

I'd like to know the url.

And if I mistook some configurations, please let me know.

Thanks and regards,

Kenji

try:

<property name="excludedContexts">${jboss.mod_cluster.excludedContexts:ROOT,admin-console,invoker,jmx-console,juddi,web-console}</property>

[funa516]

> try:

> <property name="excludedContexts">${jboss.mod_cluster.excludedContexts:ROOT,admin-console,invoker,jmx-console,juddi,web-console}</property>

I tried this, and I succeeded to access from mod_cluster httpd to jbossws.

I got following message.

  23:50:25,059 INFO  [org.jboss.web.tomcat.service.deployers.TomcatDeployment] deploy, ctxPath=/jbossws

But strange to say, after run.sh -c all -b <ip address>, and Jboss AS started,

I waited for deployment completed, but 5min, 10min, 15min, I could not get above message.

And finally, deployment was executied at a moment's notice after I access http://<jboss ap ip>:8080/jbossws directly by using Web Browser.

I don't know why deployment has not started until I access Jboss AP directly.

Anyway, thank you for your help!
