cluster-service

A service launcher supporting two modes, development and production.

In development mode (default), forever-monitor is used to launch a single instance and keep it alive.

In production mode, recluster is used to launch a node.js cluster of a given service. A PID file is created in os.tmpdir() with the file name ${pidDir}/cluster-serverice-master-${serviceName}.pid. By default, as many workers are stated as CPU cores can be detected. The cluster also listens to SIGUSR2 and SIGTERM signals.
