Recently I knew some words puppet chef salt. It seems that they are used to setup env for thousands of machines with a master machine.
But I just have one or two vps. How can I create a production env quick with these tools? I found some docs from salt but most of its docs talk about how to use master to create a new production server.
So is there some good way to create a product env for only vps.
chef, puppet etc. work exactly the same way irrespective of the number of VPS you want to manage. You basically write your server configuration in the form of code (in other words, template of a server). Then you run that code as many times as you like.
chef comes with a simpler version called chef-solo. If you have only 2 VPSs to manage, you will be happy with chef-solo, as the learning curve is much smaller.
Vagrant can be a great tool to learn chef-solo or puppet
