Question

Is it possible to turn on/off redis subscribe dynamically from the master cluster? The reason I ask is that I just want one cluster subscribed at a time, but in case that cluster dies I need to get another one to subscribe.

从根本上说,主组是否能够通过一纸pi向幸运的集群发出信息?

在主人中,你可以轻松地向集群发出信息,而你只是要挽救因“k()”电话而产生的工人物体。

var cluster = require("cluster");
worker = cluster.fork();
worker.on("message,function(msg){
  console.log("Master says:" + msg);
});
worker.send({message: hello });
