Nginx और Nodejs के साथ सबसे अच्छा और सरल सेटअप Ngin को HTTP_protocol सक्षम के साथ HTTP और TCP लोड बैलेंसर के रूप में उपयोग करना है। इस संदर्भ में, Nginx नोडज को आने वाले अनुरोधों को प्रॉक्सी करने में सक्षम होगा, और SSL कनेक्शन को बैकएंड Nginx सर्वर (एस) से भी समाप्त करेगा, और प्रॉक्सी सर्वर को ही नहीं। (एसएसएल-पासथ्रू)
मेरी राय में, गैर-एसएसएल उदाहरण देने का कोई मतलब नहीं है, क्योंकि सभी वेब एप्लिकेशन सुरक्षित वातावरण का उपयोग कर रहे हैं (या होना चाहिए)।
प्रॉक्सी सर्वर के लिए, /etc/nginx/nginx.conf में उदाहरण का विन्यास

और अंत में, 2 नोडज वीबसेर्वर्स का एक नमूना : पहला सर्वर:
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello From Nodejs\n');
}).listen(8080, "192.168.1.4");
console.log('Server running at http://192.168.1.4:8080/');
दूसरा सर्वर:
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello From Nodejs\n');
}).listen(8080, "192.168.1.5");
console.log('Server running at http://192.168.1.5:8080/');
अब सब कुछ पूरी तरह से काम और लोड-संतुलित होना चाहिए।
कुछ समय पहले मैंने लिखा था कि डॉकटर में टीसीपी लोड बैलेंसर के रूप में निगनेक्स को कैसे स्थापित किया जाए । यह जांचें कि क्या आप डॉकर का उपयोग कर रहे हैं।
