Starting HAS
Helix Authentication Service does not rely on a database because all data is stored temporarily in memory. The configuration is defined by environment variables.
After you know the service can start, see After configuring and starting HAS.
npm
The simplest way to run the Helix Authentication Service is using npm start from a terminal window. However, that is not robust because if the service fails, it must be restarted. Therefore, we recommend that you use a Node.js process manager to start and manage the service.
systemd
If you are using the systemd process manager for Linux, the systemd service unit is named helix-auth, and you can start and stop the HAS service by using the systemctl command that systemd provides.
Process Managers
Node.js process managers generally offer many advantages over using just npm to run a Node.js application. Such managers include pm2, forever, and StrongLoop. These Node.js process managers typically hook into the system process manager (for example, systemd) and thus will only go down if the entire system goes down.
