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