Hi, to make my service to do graceful shutdown,
I'm trying to write signal handler for worker processes(to flush buffered
internal logs to external log server, etc.)
but they just dies without signal handling. I don't know why and how to fix
this issue.
but code below is example. try running it and kill it(not Ctrl-C, use `kill
[pid]`)
var cluster = require('cluster');
>
> if (cluster.isMaster) {
> cluster.fork();
> function handleExit() {
> var id, w;
> for (id in cluster.workers) {
> w = cluster.workers[id];
> w.kill('SIGTERM');
> }
> };
> process.on('SIGTERM', handleExit);
> process.on('SIGINT', handleExit);
> return;
> }
>
> setInterval(function() {
> console.log('alive');
> }, 1000);
>
> process.on('SIGQUIT', function() {
> console.log('SIGQUIT');
> });
>
> process.on('SIGTERM', function() {
> console.log('SIGTERM!!!!');
> });
>
> process.on('SIGINT', function() {
> console.log('SIGINT!!!');
> });
>
> process.on('exit', function() {
> console.log('EXIT!!!');
> });
>
> process.on('message', function(msg) {
> console.log("Got Message " + msg);
> });
