Perform following steps to install your SSL certificate fast on a node.js.

Step 2: Create https_server.js file & upload SSL files to Server directory

To create the https_server.js file, use the following values. Note that, you can give any name to the Server.js file.

#vim https_server.js
var https = require('https');

var fs = require('fs');

var https_options = {

  key: fs.readFileSync("/path/to/private.key"),

  cert: fs.readFileSync("/path/to/your_domain_name.crt"),

  ca: [



https.createServer(options, function (req, res) {


 res.end("Welcome to Node.js HTTPS Servern");



path/to/private.key – the full path of the private key file.

path/to/your_domain_name.crt – the full path of the SSL Certificate file

path/to/CA_root.crt’ – the full path of the CA root certificate file.

path/to/ca_bundle_certificate – the full path of the CA bundle file

Step 3: Start Node.js
