What to choose to automatically configure servers with data replication for Wordpress?

Question

linux

It is required to create a server with several sites on wordpress, and another server for data replication, for safety net in case the main one falls, with the same settings.
Are there ready-made tools for creating such a configuration (ready-made ones, such as roots trellis, which, unfortunately, is not suitable in this case)? How do you organize your sites?
