I'd like to do a multi-server configuration of ISPConfig which has only two servers to start, web-server and database server. For now I'm not likely to use email or DNS services. I found a multi-server tutorial for Debian on five-servers which seems like overkill for me, also I'm thinking of hosting on CentOS. Are there any tutorials for a two-server config on CentOS? Or should I be able to work out how to do only a two-server install from that tutorial? I'm also thinking of installing on a single server to start, getting everything working, and then adding the dedicated database server later. Is that possible, any instructions out there on how to migrate a service to another server after-the-fact? Thanks!
