Configure systemd services

This section describes the steps you must perform to start and stop, or update, Transfer CFT from Central Governance with Linux systemd services defined.

Note To perform the authorization procedures described in this page, you may want to refer to the sudoers documentation that corresponds with your Linux operating system.

Start the service using Central Governance or Copilot

Perform the following steps to configure the Transfer CFT systemd service to start via Central Governance or Copilot, where:

  • The Transfer CFT systemd service is called: cft
  • The command to start this service is: sudo systemctl start cft
  1. Authorize the Transfer CFT user to start the service without requiring a password. On Ubuntu/Debian, use the visudo command to add a file called cft to /etc/sudoers.d/:
    2. sudo visudo -f /etc/sudoers.d/cft
  2. Then add the following line:
    3. <USERNAME> ALL=NOPASSWD:/bin/systemctl start cft
  3. Create a script in the $CFTDIRRUNTIME/conf directory, for example called copcftstart, as follows:
    4. #!/bin/sh

    sudo systemctl start cft

    rm $0
  4. Set the UCONF copilot.misc.cftstart parameter to conf/copcftstart.
    5. uconfset id=copilot.misc.cftstart, value=conf/copcftstart

Update using Central Governance with systemd services defined

Configure support for the systemd service to apply updates via Central Governance, where:

  • The systemd service created for Transfer CFT is called: cft
  • The systemd service created for Copilot is called: cftcopilot
  1. Authorize the user that operates Transfer CFT to start and stop both services without requiring a password.

    2. On Ubuntu/Debian, use the visudo command to add a file called cft to /etc/sudoers.d/:

    sudo visudo -f /etc/sudoers.d/cft

    Add the following lines:

    <USERNAME> ALL=NOPASSWD:/bin/systemctl start cft

    <USERNAME> ALL=NOPASSWD:/bin/systemctl stop cft

    <USERNAME> ALL=NOPASSWD:/bin/systemctl start cftcopilot

    <USERNAME> ALL=NOPASSWD:/bin/systemctl stop cftcopilot
  2. Create a script in the $CFTDIRRUNTIME/conf directory for each command as follows:
    1. Define a copcftstart script that starts the Transfer CFT service:

    #!/bin/sh

    sudo systemctl start cft

    rm $0
    1. Define a copcftstop script that stops the Transfer CFT service:

    #!/bin/sh

    sudo systemctl stop cft

    rm $0
    1. Define a copcopilotstart script that starts the Copilot service:

    #!/bin/sh

    sudo systemctl start cftcopilot

    rm $0
    1. Define a copcopilotstop script that stops the Copilot service:

    #!/bin/sh

    sudo systemctl stop cftcopilot

    rm $0
  3. Set the following UCONF parameters, which reference the scripts to start and stop both services.

    4. uconfset id=copilot.misc.cftstart, value=conf/copcftstart

    uconfset id=copilot.misc.cftstop, value=conf/copcftstop

    uconfset id=copilot.misc.copstart, value=conf/copcopilotstart

    uconfset id=copilot.misc.copstop, value=conf/copcopilotstop
