在多核服务器中将 socket.io 与集群一起使用的好方法? [英] Good way to use socket.io with cluster in multi-core server?

问题描述

我创建了一个在单核中运行良好的 nodejs 应用程序.此应用程序使用 socket.io 进行轻松快速的通信.

I have created a nodejs application which works fine in a single core. This application uses socket.io for light&fast communication.

现在，我想垂直扩展我的应用程序，通过使用 nodejs 中的 cluster 模块使其能够在多核系统上运行.

Now, I wanted to scale my application vertically, by enabling it to run on multi-core system using cluster module in nodejs.

我的应用程序中的所有内容都将数据存储在 Redis 中，因此，处理一些基本数据没有问题&会议.

Everything in my application stores data in Redis, therefore, there isn't a problem dealing with some basic data & sessions.

然而，当我使用集群产生多个工作进程时，似乎每个工作人员都有自己的套接字处理.

However, when I spawn multiple worker processes using cluster, it seems that each worker has its own socket handling.

例如，假设有一个名为客人"的聊天室.

For example, lets assume there is a chat room called 'guest' room.

用户 A 和用户 B 连接到房间，他们被分配到不同的工作进程.

User A and user B connects to the room, and they are distributed to the different worker process.

由于它们在不同的进程中，并且这些进程不共享套接字侦听器，因此用户 A 和用户 B 无法相互交谈.

Since they are in different processs and these processes do not share sockets listener, there is no way for user A and user B to talk to each other.

解决这个问题的好方法是什么?socket.io 是否支持多核系统?

What is a good approach to solve this problem? Does socket.io supports multi-core system?

socket.io 是否只能用于单核?

Is socket.io only for single core use?

推荐答案

您可以照常使用 socket.io，但在后台使用 redis 存储.它还将支持 socket.io 上的多个实例，而无需任何外部库.它甚至支持跨多个实例的房间.

You could use socket.io as normal but with a redis store in the background. It will also support multiple instances on socket.io without any external library. It even supports rooms over multiple instances.
