Secondary DNS on ISPCONFIG Help!

I have installed ispconfig3 on ubuntu 16.04 using the perfect server guide. I only used standard install on the "primary" server. everything functions as expected with all "optional" steps in the guide. now my question is, can i spin up a secondary ispconfig using the same steps, and then use expert mode when actually installing ISP config to set the proper variables to make it a secondary? the only guide i found was a multiserver with 5 servers. I just want a secondary dns to act as a part of my public facing name servers to resolve our hosted servers. It works already using just one, but the boss wants best practices enforced so here i am!

 

excellent, so on that note.
question 1: can i just use the root user i set up during the install of ispconfig (primary/master)? i just need a bit of elaboiration on this part as im not as skilled in sql as i would like to be.
question 2: for the secondary, can i just follow the setup guide up to, and including the "bind install" steps, then just skip to the ispconfig install section? or are there necessary steps that need to be completed to get ispconfig running that are after the bind installation step.

 

sorry, got it haha, just read the turtorial a bit more and now i got it. had to create a mysql root on the master under the fqdn and ip of my secondary, then the rest went smoothly, thank you!

 

I am aware that this thread is rather old but I still want to make a reply.
I have the same problem with two servers, I want them both to be my dns servers, on the main server I have installed the web-server and on the second one the mail server. If I configure the second server to be a mirror of the first one, bind zones are created successfully, but then I cannot create mail domains or mail accounts as in the main server the mail option is unmarked. Can I have mirrored bind zones without marking the second server to be a mirror of the first one?
