There are many things you can customize.
If you are referring to the
/usr/local/directadmin/custombuild/options.conf
file for example, you can copy that to another server. However, you still have to use the build commands to build what is in there.
When you create this directory the correct way before you are installing Directadmin, then when using setup to install DA, there is an option to use an existing options.conf file. But I don't know that command by head, it's in the
docs.
Also other customisations made, can be ofcourse copied. Depending on how you want to work.
If you mean you want to create some template yourself, which has everything included, which you can copy to a new server and then when using setup the server is installed and configured exactly the same as the other server, then I don't know if that is possible.
There are people here which do some default setup, maybe somebody will know.
Maybe
@Zhenyapan or
@jamgames2 any clue on this?
