config apache mod_cluster

[fnossair]

i installed an apache server with mod_cluster.

i used this config

LoadModule proxy_module /appli/apache2/modules/mod_proxy.so

LoadModule proxy_ajp_module /appli/apache2/modules/mod_proxy_ajp.so

LoadModule slotmem_module /appli/apache2/modules/mod_slotmem.so

LoadModule manager_module /appli/apache2/modules/mod_manager.so

LoadModule proxy_cluster_module /appli/apache2/modules/mod_proxy_cluster.so

LoadModule advertise_module /appli/apache2/modules/mod_advertise.so

## MOD_CLUSTER_ADDS

<IfModule manager_module>

  Listen adr_server:8796

  ManagerBalancerName mycluster

<VirtualHost adr_server:8796>

    <Directory />

     Order deny,allow

#     Deny from all

     Allow from all

    </Directory>

    EnableMCPMReceive

    KeepAliveTimeout 300

    MaxKeepAliveRequests 0

    #ServerAdvertise on http://@IP@:6666

    AdvertiseFrequency 5

    #AdvertiseSecurityKey secret

    #AdvertiseGroup @ADVIP@:23364

    <Location /mod_cluster_manager>

       SetHandler mod_cluster-manager

       Order deny,allow

#    Deny from all

       Allow from all

    </Location>

  </VirtualHost>

</IfModule>

but it doesnt work, and i have this message in the apache error log file "[warn] proxy: No protocol handler was valid for the URL /. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule."

can any bady help me?

Your mod_cluster seems to be advertizing connections to HTTP but you have only loaded the AJP module for mod proxy (LoadModule proxy_ajp_module /appli/apache2/modules/mod_proxy_ajp.so).

SO you either need to load this module:

LoadModule proxy_http_module modules/mod_proxy_http.so 

Or switch your AS isntallation to use AJP instead of HTTP (I would recommend this option).

this is what i did in the AS installation :

<subsystem xmlns="urn:jboss:domain:modcluster:1.0">

                <mod-cluster-config advertise-socket="modcluster" proxy-list="adr_apache:8796">

                    <dynamic-load-provider>

                        <load-metric type="busyness"/>

                    </dynamic-load-provider>

                </mod-cluster-config>

            </subsystem>

<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false" instance-id="server-web1">

                <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>

                <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>

                <virtual-server name="default-host" enable-welcome-root="true">

                    <alias name="localhost"/>

                    <alias name="example.com"/>

                </virtual-server>

            </subsystem>

is that correcte?

what can i change to switch the AS isntallation to use AJP?

thanks for your help

Please, update your AS7 and mod_cluster, if you can.

urn:jboss:domain:modcluster:1.0 suggests you are not really up to date.

If you set <mod-cluster-config connector="ajp"...

it will use the connector indicated.

[fnossair]

tkans for your reply

but how can i update mod_cluster without updating the AS7?

[rhusar]

For that you would have to update entire AS7 installation.
