我想使pm2集羣模塊與socketio一起工作，但是當我訪問/ hello時出現錯誤。 鑑於集羣利用了所有的CPU核心，socketio會感到困惑，所以我安裝了socket.io-redis模塊來處理這個，但它看起來好像根本不會做任何與Redis（它是空的）或socket .io，我可能錯過了一些非常明顯的東西。使用pm2的集羣模塊與socket.io和socket.io-redis
我使用Nginx作爲Web服務器，我的express服務器localhost：8000指向localhost：80。
檢查：
Nginx的作品，http://localhost/hello回報socketio的反應，我看到它的瀏覽器控制檯上。
Redis的實例是
它的工作原理，如果我開始我的服務器npm start不使用集羣，但在sudo pm2 start bin/www -i 0問題的底部產生錯誤。
