Read the upgrade guide first!

Preflight Checklist

Before you begin, confirm the following:

  • FileMaker Server is installed and running on your server
  • You have Fully Qualified Domain Name (FQDN) for your server and a valid SSL certificate. The Claris default self signed cert is not sufficient for OttoFMS to work.
  • Your server machine meets the minimum requirements to run OttoFMS
  • You have administrator rights to your server
  • You can access the FileMaker Server Admin Console
  • You have your free OttoFMS license key (opens in a new tab)
  • You can access the OttoFMS license server at (opens in a new tab) using a web browser within your network. If you get a time-out error or you get a blank page, you may need to modify your firewall or network access rules to allow access.

OttoFMS expects FileMaker Server to be running with the default fmserver user and fmsadmin group privileges. This is set during FileMaker Server installation. It is very rarely changed, but if you did change it, OttoFMS will not install correctly.

Select your operating system for specific installation instructions:

Additional preflight checks for Linux:
Make sure your server has a swap file configured for additional virtual memory.

Option 1: Install using our install script

We have set up a hosted install script that you can run on your server to install OttoFMS. This script can also be used to update to a different version of OttoFMS later.

To run, simply copy and paste the following command into your terminal:

sudo curl -sSL "" | bash

If you'd like to install a specific version of OttoFMS, you can specify the version number as a parameter:

sudo curl -sSL "" | bash -s -- -v 4.1.0

Option 2: Manual Install

SSH into your Linux Server

Add installer to Server via FTP or SFTP

The download package you receive is a zip file, unzip it for the actual installer

cd to the directory containing the downloaded installer file

Run the installer via command line

sudo apt -y install ./ottofms-app_|version|_amd64.deb

For example:

sudo apt -y install ./ottofms-app_1.0.0_amd64.deb

Post-Installation Setup
