It sounds like you need configuration management software. You already have several machines by the sounds of it, so it's a good time to look in to it. Ansible can be very simple and quick to learn and everything you've mentioned in your post can easily be done with it. I found Puppet a bit of a nicer thing to develop in, but a lot more complicated and a lot more work to keep up to date, so I switched to Ansible. Other configuration management software is available and I don't think it matters that much which one you go for; you will no doubt discover your preferences. All configuration management solutions will cover the use case of different config for different hosts or groups of hosts, templating of configuration files, and pushing files and assets out to where they need to be. You can invent your own with a big shell script and an ssh loop but to be honest, Ansible is really very simple, may as well use something that has solved all these problems.
