    So I have read the howto's, but I am confused on a couple of points:

    How is the configuration between two apache web servers sync'd? Does ISP config manage multiple server configurations?

    If there is 2 NFS servers that hold the data for the websites, then those servers need ftp. How is the login information synced?

    Anyone that could answer these would be my new best friend.

    Are you referring to the APache-cluster howto? The configuration isn't synced between the Apache nodes, why should it be?

    No, not in the current version. This will be available in ISPConfig 3.

    The NFS servers don't need FTP. You need an FTP account on the NFS client. The FTP user can then upload to the NFS share which will be snyced between the two NFS nodes (with DRBD).

    Thanks for the reply! With regards to apache configuration, the configuration needs to be synced because if I add a virtual host on one, then the other would also need to know it?

    Also with the ftp issue, I understand that I asked the wrong question. How do I keep the ftp user accounts in sync between the nfs clients?

    Normally you host one big web site on such a cluster and don't change the Apache configuration very often. I wrote the tutorials with this in my mind.
    If you change your Apache configuration often, you have to find a solution for yourself if you don't want to sync manually. Maybe put the configuration on an NFS share?

    If you have just one client, then there's no problem. If you have multiple clients, you must do it manually or find another solution.
