Create and activate a virtualenv for the next steps 
virtualenv venv
source venv/bin/activate

Install Python Libraries

Ubuntu 
sudo pip3 install wheel pycairo
!!! note Use of pip with sudo is not recommended, and you will be warned about this!
Centos/RHEL/Fedora 
pip install wheel pycairo

Remove Old Installation

YOU MUST DO THIS IF:

  • Free TAK Server has been installed before
  • An upgrade fails
  • A previous installation was not completed
Ubuntu 
sudo pip3 uninstall FreeTAKServer
sudo pip3 uninstall FreeTAKServer-UI
Delete the database and log folders 
sudo rm /opt/FTSDataBase.db
sudo rm -r /usr/local/lib/<your-python-version>/<dist or site>-packages/FreeTAKServer
Centos/RHEL/Fedora 
deactivate
rm -rf venv/
pip uninstall FreeTAKServer FreeTAKServer-UI
Delete the database and log folders 
sudo rm /opt/FTS/FTSDataBase.db

Install FreeTAKServer

Install the FreeTAKServer and the associated Web UI

Ubuntu 
sudo python3 -m pip install FreeTAKServer[ui]
Centos/RHEL/Fedora 
pip install FreeTAKServer[ui]

The FreeTAKServer can be installed without the UI, however this makes the server much more difficult to use and is probably not what you want. This can be done using the FreeTAKServer pip package only.

Advanced Installations:

Install a specific version To install a special version of a FreeTAKServer pip package by appending `==version-number` to the installation command. 
python3 -m pip install FreeTAKServer[ui]==version-number
For example, if you want to install version Alpha of the requests package, you can run the following command: 
python3 -m pip install FreeTAKServer[ui]==0.2.0.13
Old installations can be installed in the same way, if desired. This will download and install version 0.2.0.13 of FreeTAKServer. If no version number is specified, then the latest normal release will be installed.

Check Installation

The pip utility allows the user to check the installation and dependency status of a package.

pip check FreeTakServer

You should see No broken requirements found. displayed, in which case you can proceed. Otherwise, there was an issue with the pip installation, and you should investigate the pip-generated installation logs for more information.

Configure and Run FreeTAKServer

FTS versions older than 1.9 are not configured this way. For versions <1.9 you will need to locate older versions of this document in the repo history.

Start the FreeTAKServer

Ubuntu 
sudo python3 -m FreeTAKServer.controllers.services.FTS
Centos/RHEL/Fedora 
python -m FreeTAKServer.controllers.services.FTS

:memo: Note: Warnings about failed to register component are OK. Your system will run fine with these warnings. Starting with FTS 2.0 some future functionality is declared but not fully implemented.

On the first run, a configuration wizard will help set up the config file.

:memo: Note: If the wizard does not appear, see troubleshooting.

Using the Wizard

The default configuration option is presented in [brackets]. If the default is acceptable you can simply press enter without entering any text to automatically use the default.

An example is provided below, your exact configuration will differ.

would you like to use a yaml config file, 
 if yes you will be prompted for further configuration options [yes]:
where would you like to save the yaml config [/opt/fts/FTSConfig.yaml]: 
enter ip [127.0.0.1]: 
enter the preferred database type (MySQL is highly experimental if you're not sure leave default) [SQLite]: 
enter the preferred database path [/opt/fts/FTSDataBase.db]: 
enter the preferred main path [/usr/local/lib/python3.11/site-packages/FreeTAKServer]: 
enter the preferred log file path [/opt/fts/Logs]:

:memo: Note: The IP in this configuration wizard is the FTS_MAIN_IP. This must be your EXTERNAL IP.

MySQL usage is beyond the scope of this guide, if you wish to use MySQL, it is assumed you know how to configure database servers already. Some additional information for MySQL installations is available in the FTS-UI configuration section.

The database and log filepaths can be anywhere that the server's host user can access.

The main path should be the directory where pip installed FreeTAKServer. This can be found under your python packages directory. In virtualenv installations, it is inside the virtualenv directory.

The wizard creates the YAML configuration file under the location you selected, the default location is /opt/fts/FTSConfig.yaml.

FreeTAKServer will then proceed start all the services.

FTS Configuration

Manual FTSConfig.yaml

Warning

Before modifying the YAML file, FreeTAKServer must be stopped!

Use the keyboard chord CTRL + C twice in the console running FTS to stop FreeTAKServer.

A separate guide is maintained for manual configuration of your FTS install.

MainConfig.py

FTS sends a welcome message on client connection which is configurable. See the FreeTAKServer/core/configuration/MainConfig.py file to change it.

ConnectionMessage = f'Welcome to FreeTAKServer {version}. The Parrot is not dead. It’s just resting'

FTS-UI Configuration

Edit the config.py file in the FreeTAKServer-UI directory where it was installed by pip

Where is that? > The FreeTAKServer-UI directory lives at the same level as the FreeTAKServer directory that was set in the initial configuration of FTS. >Usually that means it's inside your python packages directory. In virtualenv installations, it is inside the python installation in side the virtualenv directory.

Standard UI Config

Edit the IP value to your external IP, for example:

# this IP will be used to connect with the FTS API
IP = '192.168.1.100'

Set the web map IP address, for example:

# the public IP your server is exposing
APPIP = '0.0.0.0'
# webmap IP
WEBMAPIP = "192.168.1.100"

In a default installation, the port should be 19023. Advanced users may wish to use a different port.

# Port the  UI uses to communicate with the API
PORT = '19023'

Custom Secrets Configuration

The following items can be updated to use your own secrets, however the values must be updated in both the FreeTAKServer-UI/config.py and the FreeTAKServer/core/configuration/MainConfig.py files.

The API key used by the UI to communicate with FTS. Generate a new system user and then set it.

app.config['APIKEY'] = 'Bearer [API_TOKEN]'
app.config['WEBSOCKETKEY'] = '[Your_Web_socket_Key]'

MySQL Configuration

To use a MySQL database, update the URI to point to your database.

Database setup is beyond the scope of this document.

SQLALCHEMY_DATABASE_URI = 'mysql://' + 'user:pass@localhost/dbname'

Miscellaneous Parameters

Some additional parameters can be found in the __init__.py file in the FreeTAKServer-UI/app/__init__.py directory.

These configure dashboard update frequency, ~~health pings?~~, ~~status messages?~~, and the file size limit for data packages.

app.config['USERINTERVAL'] = '180000';
app.config['SERVERHEALTHINTERVAL'] = '180000';
app.config['SYSSTATUSINTERVAL'] = '600000';
app.config['DATAPACKAGESIZELIMIT'] = '15360000';

Start UI

In the terminal, navigate to the FreeTAKServer-UI directory wherever it was installed by the pip utility.

Start the UI from the terminal using python:

Ubuntu 
sudo python3 run.py
Centos/RHEL/Fedora 
python run.py

You will see the UI server start up in your terminal, which should look similar to that shown below.

(55501) wsgi starting up on http://0.0.0.0:5000
(55501) accepted ('192.168.1.100', 49842)

Next Steps

Create a service

To run the server without keeping the console open, a service can be created.

See: Service

Installation on a Separate machine

Typically, the web UI is installed on the same machine as FTS; however, you can install it on a separate machine and even use it to manage several instances.

If you're installing FTS-UI on a separate server the following commands may help:

sudo pip install WTForms==2.3.3
sudo pip install SQLAlchemy==1.3.20
sudo pip install eventlet

The config file will also need to be updated.

IP = '[FTS external IP]'
APPIP = '[FTS-UI internal IP]'

Check Installation

After finishing all the steps, make sure your configuration is acceptable and server running properly.

sudo python3 -m FreeTAKServer.controllers.services.FTS

If you see FTS start without error you may hit ctrl+c twice and move onto running FTS.

your FTS is now configured

If you have set up the UI, from the Admin console send a message hello world to the client

Troubleshooting

Default Login

The default credentials for the UI are admin and password.

You are encouraged to update these quickly.

WTForms Error Troubleshooting

In the event of a wtforms error, install it using pip:

pip3 install WTForms==2.3.3

Failed to Register Components

Warnings about failed to register component are OK. Your system will run fine with these warnings. Starting with FTS 2.0 some future functionality is declared but not fully implemented.

UI Can't See Server

Usually this happens when you are using an OS that has a strong default firewall.

Ensure all the ports you have set in your config files are open on the firewall for TCP traffic.

Centos/RHEL/Fedora 
firewall-cmd --add-port=19023/tcp
