Are you saying you would have two physical machines, each machine would be running: One webserver (ie: IIS or Apache) and CF Ent with two instances
So you would have a total of four CF instances in two clusters across two physical machines? That should work fine. You'd just install CF, setup the instances, then setup the clusters, then connect the clusters to the webservers using either the wsconfig GUI or commandline app. I am not sure what the ports question refers to. The webservers would be running on port 80/443, and those would typically be the only ports visible to the outside word (or to the loadbalancer). If you have installed CF on JRun there will be a few JNDI ports int he 2900 range used by JRun to manage the cluster, a couple of ports in the 51000 range used by the webserver connector as a proxy to the webserver, and a couple of ports in the 8300 range used for the build in JRun webserver (which you should hardly ever use directly). The 2900 range ports should be visible among all the CF instances and will be used to discover cluster members, the webservers need to see the 51000 range ports to pass requests, the 8300 range ports don't really matter unless you are doing some kinda config task, and the 80/443 ports need to be visible to anyone requesting pages fromt he internet or loadbalancer.. -Cameron Mark Ireland wrote: > I am considering two webservers each with 2 coldfusion instances, where one > instance has the higher priority apps on it. > > If this is advisable, I want to know how the ports might be setup? > > >> From: Cameron Childress <[EMAIL PROTECTED]> >> Reply-To: [email protected] >> To: CF-Server <[email protected]> >> Subject: Re: Hardware Load Balancing >> Date: Wed, 18 Jul 2007 16:23:32 -0700 >> >> Actually, for a ColdFusion Cluster, you just need more than one >> ColdFusion instance, not more than one webserver.
