Description

Failure with mod_cluster

Having the following setting:

mod_cluster.conf

LoadModule slotmem_module modules/mod_slotmem.so
LoadModule manager_module modules/mod_manager.so
LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
LoadModule advertise_module modules/mod_advertise.so

MemManagerFile "/tmp/mod_cluster-eap6/jboss-ews-2.0/var/cache/mod_cluster"
ServerName [2620:52:0:105f::ffff:50]:2080

<IfModule manager_module>

      SetHandler mod_cluster-manager
      Order deny,allow
      Deny from all
      Allow from all
    </Location>
  </VirtualHost>
</IfModule>

I get a weird proxy: DNS lookup failure as soon as worker sends CONFIGURE}:

access_log

An attempt to access the mod_cluster manager console yields an unpleasant NOTOK (obviously, we have All workers are in error state...):

curl -g [2620:52:0:105f::ffff:50]:6666/mcm

You might take a look at the logs: error_log-mod_cluster, access_log-mod_cluster.

ProxyPass itself works just fine

On the other hand, when I had tried this:

proxypass.conf

LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

ServerName [2620:52:0:105f::ffff:50]:2080
Listen [2620:52:0:105f::ffff:50]:6666

    <Directory />
        Order deny,allow
        Deny from all
        Allow from all
    </Directory>
</VirtualHost>

I received:

And from the client's side, it worked:
curl -g [2620:52:0:105f::ffff:50]:6666/ brought me the worker's home page (EAP's welcome in this case).

Take a look at the whole log error_log-proxypass.

Note: The http.conf was the same both for mod_cluster and for proxypass test.
