recluster.js

//https://www.npmjs.com/package/recluster
var recluster = require('recluster'),
    path = require('path');
 
var cluster = recluster(path.join(__dirname, 'server.js'),{workers : 2});

cluster.run();
 
process.on('SIGUSR2', function() {
    console.log('Got SIGUSR2, reloading cluster...');
    cluster.reload();
});
 
console.log("spawned cluster, kill -s SIGUSR2", process.pid, "to reload");
//Use this command to kill and reload the nodejs cluster
//[root@linux90 ~]# kill -s SIGUSR2 2091
