How can I programmatically shutdown a node program and restart it without using any libraries?

问题

I need to shutdown a node program and have it restart. I need to do this within the itself program without having to use something like forever needing to be setup.

I know I can use process.exit() to shut the program down, but anything I can think of that would open it back up that I can kick off from within node would be killed by process.exit() before it could finish. Is there a way I'm not seeing to detach a exec call from the process before I exit? Any other ideas? Do I have to suck it up and go use forever?

回答1:

Quick and dirty, not very well tested:

var child_process = require('child_process');

process.on('SIGINT', function() {
  console.log('restarting...');
  child_process.fork(__filename); // TODO: pass args...
  process.exit(0);
});

console.log('Running as %d', process.pid);

setTimeout(function(){}, 1000000); // just some code to keep the process running
