Reboot Linux from node.js without fork()ing /sbin/shutdown or going thru initscripts

node-reboot

Reboot Linux/macOS kernel immediately from node without calling /sbin/shutdown or going thru initscripts.

Why?

I'm running a cluster of Linux servers which boot readonly and perform a memory-intensive computations. node-reboot is a part of a watchdog application, which in case of emergencies much reboot the server immediately without fork()ing another process or going thru upstart/initscripts.

Synopsis

Call sync() and then reboot:

require('reboot').reboot();

Reboot without sync()ing:

require('reboot').rebootImmediately();

The function should never return. If it does, it means node has insufficient permissions.

Permissions (Linux only)

If you are to run node process under non-superuser, be sure to give node permissions to reboot the system:

sudo setcap CAP_SYS_BOOT=+ep /usr/local/bin/node

See man capabilities for details.

Installation

npm install reboot

or

npm install .
