Installing Otto on Linux

Before you begin


Checking off each item in this list before you start the actual installation will help ensure the that everything goes smoothly.

  • FileMaker Server is installed on your server.
  • Your server meets the minimum requires for Otto. See Tech Specs.
    • Make sure your server has a a swap file configure for addional virtual memory.
  • Port 3030 is open.
    • FileMaker Server installs a firewall that will block port 3030, unless you open it. See below for instuctions on how to do that.
  • You know your SSL Passphrase, if your server uses an SSL certificate that requires one.

Otto 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, Otto will not install correctly.


  1. SSH into your Linux server.
  2. Download the installer file, or upload it with SFTP or FTP from your desktop.
    • The download package you received is a zip archive. Unzip it to get to the actual installer.
    • To access your file downloads, log in to your account and navigate to the Purchase History tab.
  3. cd to the directory containing downloaded installer file
  4. Run the installer via command line
sudo apt -y install ./otto-app_|version|_amd64.deb

Make sure you substitute |version| for the version string found in the new installer. For example,

sudo apt -y install ./otto-app_3.0.1_amd64.deb

Installing license

Open Otto's web console at port 3030 on your server. Follow the prompts to enter your license key.

Opening ports

The following commands will open port 3030 in the firewall that FileMaker Server installs.

sudo firewall-cmd --permanent --add-port=3030/tcp
sudo firewall-cmd --reload
