Autoinstall works if you just want a database server that you manage with ISPConfig. If you have an existing ISPConfig setup, and want to add a new server, that works also, read the documentation page on "ISPConfig 3 in a Multiserver- and Cluster environment".
Thanks for the answer I have installed the latest web and dns servers with Code: wget -O - https://get.ispconfig.org | sh -s -- But reading the --help for it I can't se I can do a MariaDB ONLY install. So assume I have to do it like in the documentation and install manualy.
The autoinstall has --no-web, --no-dns, --no-mail, --no-roundcube, --no-ftp. If that leaves installed something you do not want, turn off those services.
You do not need to since all ISPConfig server has MariaDB installed and each servers run its own database, to make each work faster and more efficient. In a web server you set up, backup routine can also be set for each websites too, for both files and database. You do not need to, as explained above.
We run multiple server on not so power full servers. So to distribute the load we use multiple servers. It works wary well I ended up running this: Code: wget -O - https://get.ispconfig.org | sh -s -- --no-web --no-mail --no-roundcube --no-dns -no-ftp --use-php=system And adding the server to the existing server in expert mode. Thanks for the help.
