Re: load-balancing-with-apache-karaf-cellar-and-mod_proxy_balancer

[asookazian2 <as...@gmail.com>]

I have a Mac host with 3 VM's: one Win7 for Karaf node, another Win7 for
Karaf node and one Ubuntu for httpd.

following directions here: 
http://blog.nanthrax.net/2013/02/load-balancing-with-apache-karaf-cellar-and-mod_proxy_balancer/
<http://blog.nanthrax.net/2013/02/load-balancing-with-apache-karaf-cellar-and-mod_proxy_balancer/>  

I have added the following config to /etc/apache2/apache2.conf in Ubuntu
13.10 distro.  Note that there is no /etc/httpd dir.  Following URL is
working on Ubuntu: http://localhost (I see the "It works!", etc.)

I edited the apache2.conf file and stopped/started apache2 service:

service apache2 stop
service apache2 start

Contents of config change in /etc/apache2/apache2.conf:

<Proxy balancer://mycluster>
  BalancerMember http://192.168.2.111:8181
  BalancerMember http://192.168.2.110:8181
</Proxy>
ProxyPass /ws balancer://mycluster

<Location /balancer-manager>
  SetHandler balancer-manager
  Order allow,deny
  Allow from all
</Location>

I added this config at the very bottom of the file w/o editing anything
else.

I started karaf on both nodes of the cluster.  I am able to navigate to
http://localhost:8181/ws on both nodes.

When I navigate to http://localhost/balancer-manager I get:

The requested URL /balancer-manager was not found on this server.

Plz advise how to fix.  thx.
