Reference

CreateBalancers

This configuration option defines how the mod_cluster balancers are created in the httpd virtual hosts. Possible values are:

• 0: Create a balancer in all VirtualHosts defined in httpd.
• 1: Do not create balancers. In this case one or more balancers are created only when a ProxyPass or a ProxyPassMatch directive that specifies the balancer by name (as balancer://<balancer-name>/) is encountered. If this option is used, the balancer must be configured in the ProxyPass directive, because the default is empty sticky session and nofailover=Off, and the values received via the MCMP CONFIG messages are ignored.
• 2 (the default configuration): Create only the main server.
