How to kill childprocess in nodejs?

问题:

Created a childprocess using shelljs

!/usr/bin/env node

require('/usr/local/lib/node_modules/shelljs/global');
   fs = require("fs");  
   var child=exec("sudo mongod &",{async:true,silent:true});

   function on_exit(){
        console.log('Process Exit');
        child.kill("SIGINT");
        process.exit(0)
    }

    process.on('SIGINT',on_exit);
    process.on('exit',on_exit);

Child process is still running .. after kill the parent process

回答1:

If you can use node's built in child_process.spawn, you're able to send a SIGINT signal to the child process:

var proc = require('child_process').spawn('mongod');
proc.kill('SIGINT');

An upside to this is that the main process should hang around until all of the child processes have terminated.
