Hello everyone !! Well I have been following the Ispconfig emails, dns, sites, mysql cluster on debian 8 for setting up ispconfig in HA. I noticed that the tutorial is related to ispconfig Master-Slave architecture. However I want to set up ispconfig Master-Master Setup where if one of my ispconfig node fails than other node can handle to read/write request. The in the current turorial I am only able to add sites,emails on the master server and not from the slave server, if my master server goes down than client wont be able to add new sites from the slave server. Is there any way i can deploy master-master archtecture for HA ???
