i am still confused. what is then the right order to install ISPconfig on the listed five VMs? each one of them has mysql-server installed.

1) install ISPconfig on the DB VM and choose for all the server-roles "no"
2) install ISPconfig on the admin VM and choose only for server role "ISP config GUI" yes
3) install ISPconfig on the web/ftp VM and choose the appropriate roles (web, jailkit, ftp)
4) install ISPconfig on the dns VM and choose the dns role.

or do i have to FIRST install the ISPconfig instance on the admin server and then all the others? but i would like to have the "main" dbispconfig on the DB server and all other instances syncing with that one. (so that i mainly have one DB server that needs to be accessible from the other servers).

thanks for your help & have a nice weekend
