  1. Navigate to the directory /opt:

    cd /opt

  2. Clone the FediFetcher repository from GitHub:

    git clone https://github.com/nanos/FediFetcher.git

  3. Create a Python Virtual Environment named fedifetcher:

    python3 -m venv fedifetcher

  4. Change to the FediFetcher directory:

    cd FediFetcher

  5. Activate the virtual environment:

    source /opt/fedifetcher/bin/activate

  6. Install the required Python packages from the requirements.txt file:

    pip install -r requirements.txt

  7. Deactivate the virtual environment:

    deactivate

  8. Configure FediFetcher according to the instructions provided at: Configuration Options.

  9. Run FediFetcher for the first time:

    /opt/fedifetcher/bin/python3 find_posts.py -c=artifacts/config.json

  10. Create a systemd service file for FediFetcher:

    nano /etc/systemd/system/fedifetcher.service

    Paste the following content:

    [Unit]
Description=FediFetcher Service
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/opt/FediFetcher
ExecStart=/opt/fedifetcher/bin/python find_posts.py -c=artifacts/config.json

[Install]
WantedBy=multi-user.target

  11. Create a systemd timer file for FediFetcher:

    nano /etc/systemd/system/fedifetcher.timer

    Paste the following content:

    [Unit]
Description=FediFetcher Timer

[Timer]
OnCalendar=*-*-* *:*:00
Persistent=true

[Install]
WantedBy=timers.target

    Explanation:

    • OnCalendar: This option defines when the timer should elapse. The format is YYYY-MM-DD HH:MM:SS. *-*-* *:00:00 means every hour, *-*-* *:*:00 means at the start of every minute. So, the timer will trigger every minute. More informations.
    • Persistent=true: This option ensures that if the system is unable to trigger the timer at the specified time (e.g., if the system is asleep or powered off), it will run the missed events when the system is next awake or powered on.
    • WantedBy=timers.target: This specifies that the timer should be enabled when the timers.target is active, which is usually during system startup.

  12. Reload the systemd daemon configuration:

    systemctl daemon-reload

  13. Start the FediFetcher timer and enable it to start at every system boot:

    systemctl start --now fedifetcher.timer

With these steps, FediFetcher should be successfully set up on your system and automatically started to fetch posts regularly.
