Topic: Multiple Clusters on Apache 2.4

[sri_tnj]

Dear!

I wanted to configure 2 clusters on Apache 2.4. Here are my sample configurations

Cluster 1 config:
----------------

<VirtualHost *:80>
ServerName mywebsite1.com
<IfModule mod_proxy_balancer.c>
<Proxy balancer://sgcluster>
BalancerMember http://IPaddress1:80/ loadfactor=1
BalancerMember http://IPaddress2:80/ loadfactor=2
ProxySet lbmethod=byrequests
</Proxy>
ProxyPass / balancer://sgcluster/
ProxyPassReverse / balancer://sgcluster/
ProxyPassReverseCookieDomain sgcluster mywebsite.com
</IfModule>
</VirtualHost>

Cluster 2 config:
-----------------
<VirtualHost *:80>
ServerName mywebsite2.com
<IfModule mod_proxy_balancer.c>
<Proxy balancer://aucluster>
BalancerMember http://IPaddress3:83/ loadfactor=1
BalancerMember http://IPaddress4:83/ loadfactor=2
ProxySet lbmethod=byrequests
</Proxy>
ProxyPass /account balancer://aucluster/account
ProxyPassReverse /account balancer://aucluster/account
ProxyPassReverseCookieDomain aucluster mywebsite.com

</IfModule>
</VirtualHost>


I've included both configuration file in httpd.conf.
I'm getting the errors, when I tried to start up the apache.

Your kind help is highly appreciated.
