[users@httpd] mod_proxy_balancer problem

[PIRONET Benoit <Be...@sword-technologies.com>]

Hello everybody

 

I have an apache 2.2.4 on a freebsd 5.4 server.

 

I try to set up a virtual host with load balancing. 

 

Here is a part of my httpd.conf: 

LoadModule proxy_module libexec/apache22/mod_proxy.so

LoadModule proxy_balancer_module libexec/apache22/mod_proxy_balancer.so

LoadModule proxy_http_module libexec/apache22/mod_proxy_http.so

LoadModule proxy_connect_module libexec/apache22/mod_proxy_connect.so

LoadModule proxy_ftp_module libexec/apache22/mod_proxy_ftp.so

LoadModule proxy_ajp_module libexec/apache22/mod_proxy_ajp.so

 

The load balancer status:

<Location /balancer-manager>

SetHandler balancer-manager

 

Order Deny,Allow

Deny from all

Allow from all

</Location>

 

And the configuration of my vhost for load balancing:

<VirtualHost *:80>

        ServerName lbtest.lifeonline.be

        ServerAdmin benoit.pironet@gmail.com

        ProxyPass / balancer://mycluster2 stickysession=PHPSESSIONID
nofailover=On

        <Proxy balancer://mycluster2>

                BalancerMember http://www.lifeonline.be:80

        </Proxy>

        ErrorLog /var/log/http-balancer_error

</VirtualHost>

 

I get two problems: 

 - I can't get sub-ressources out of a balanced host using the load
balancer virtual host. 

   I get this error in the error log file: 

[Sun Mar 25 18:49:00 2007] [warn] proxy: No protocol handler was valid
for the URL /img/logo.jpg. If you are using a DSO version of mod_proxy,
make sure the

proxy submodules are included in the configuration using LoadModule.

 

I read on the web that sub modules of mod_proxy has to be enabled but
they are. And I don't find any other solution.

 

The second problem is about http://www.lifeonline.be/balancer-manager
The url runs but no balancing options are proposed. I only get this:


Load Balancer Manager for www.lifeonline.be


Server Version: Apache/2.2.4 (FreeBSD) mod_ssl/2.2.4 OpenSSL/0.9.7e

Thank you very much for your help,

If you are using mod_proxy_http you have to create one ProxyPassReverse
for each BalancerMember you define in the balancer.
