How to use Corridor-Daemons to start, stop, and check the status of Corridor Platform processes.

This section describes how to use Corridor-Daemons to manage the corridor processes for each component of the platform, as an alternative to an OS-level tool like Systemd. Daemons can be used to:

  • start
  • stop
  • check status of the processes.

Installation

Section titled “Installation”

There is no system dependency in case of Corridor-Daemons, so no additional installation is required.

Configuration

Section titled “Configuration”

No additional configurations are required when running Corridor processes using Corridor-Daemons. We can use the below set of commands to start/stop/check_status. The logfile and pidfile for each process can be saved at custom locations by using the parameters:

  • logfile: location of the log file
  • pidfile: location of the pid file

The default logfile directory is: INSTALL_DIR/instances/INSTANCE/logs

The default pidfile directory is: INSTALL_DIR/instances/INSTANCE/pids

To start the processes, we can do:

Terminal window
INSTALL_DIR/venv-api/corridor-api daemon start
INSTALL_DIR/venv-api/corridor-worker daemon start
INSTALL_DIR/venv-app/corridor-app daemon start
INSTALL_DIR/venv-jupyter/corridor-jupyter daemon start

To stop the processes, we can do:

Terminal window
INSTALL_DIR/venv-api/corridor-api daemon stop
INSTALL_DIR/venv-api/corridor-worker daemon stop
INSTALL_DIR/venv-app/corridor-app daemon stop
INSTALL_DIR/venv-jupyter/corridor-jupyter daemon stop

To check the status of the processes, we can do:

Terminal window
INSTALL_DIR/venv-api/corridor-api daemon status
INSTALL_DIR/venv-api/corridor-worker daemon status
INSTALL_DIR/venv-app/corridor-app daemon status
INSTALL_DIR/venv-jupyter/corridor-jupyter daemon status
