Before you install on multiple machines

• Read Before you install FileMaker Server.

• Ensure that no existing websites on the primary or secondary machines use port 80 or 443. These ports are used by FileMaker Server on both machines. If the FileMaker Server installer detects existing websites using these ports, you must disable those websites and make the ports available.

• If you already have a single-machine deployment of FileMaker Server, you can add a secondary machine to your existing deployment. To add a secondary machine, install FileMaker Server on the secondary machine; see Installing on a secondary machine (Windows and macOS) and Installing on a secondary machine (Linux). Then in the secondary machine Admin Console, connect to the existing, primary machine.
