Hello all, I think I already know the answer, but prefer to ask. Is there a matter to have not only one server the ISPConfig Web-Interface in a cluster. I mean, if I add a server to the cluster, with Apache server and ISPConfig Web-Interface enabled at the install, will I be able to connect to THIS server to manage the cluster as I use the first one. In one word, can I choose between multiple server to manage the same cluster? Thank you!
This depends on the setup of your cluster. Normally there is just one master server, if you attach another server to this master, then this additional server amy not run a ispconfig interface. If you would install a interfacethere, then any change you do there will cause a conflict with changes that you do in the master server and the system will break sooner or later. An example for such a setup is this guide: http://www.howtoforge.com/multiserv...se-servers-on-debian-squeeze-with-ispconfig-3 If you setup the two servers as mirror system like it is desctibed in thsi guide: http://www.howtoforge.com/installin...tabase-cluster-on-debian-6.0-with-ispconfig-3 Then you will be able o use the ispconfig interface on both servers because the ispconfig database of the first and second server are mirrored with mysql master/master replication. So changes get synced in both directions.
Thank you for the answer ! That's what I was thinking, and that's logic... Ok, I'm gonna keep only one master with the interface so. Thanks again for the advice.
Sorry for waking such an old discussion, can there be master-master-master-master-master mirrored panels?
As per your answer above @till, I am building this setup with three servers instead of two and using mariadb galera cluster instead of mysql master/master replication; so this setup should still be safe to install ISPConfig interface on the second and/or third, right or am I wrong? I am also interested to know about unison which from my readings is supporting any two servers, so if I want to add support for third servers for /var/www and other path like /etc/letsencrypt etc., is it better that I simply add unison on the second server to resync with the third server; or that I use other sync software like lsyncd so all servers can be resynced at once?
