Deploying a Node.js Application to an ECS Instance

In the previous article, we have discussed how to deploy a local Java application directly to an Alibaba Cloud Elastic Compute Service (ECS) instance, and received a lot of feedback from our readers. So to help answer the questions from our readers, we will further introduce how to deploy a Node.js application to an Alibaba Cloud ECS instance in this article.

Develop an Application Locally

const http = require('http');
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Alibaba Cloud Toolkit: Hello World');
});
server.listen(port, '0.0.0.0', () => {});

The preceding code is a standard Node.js project used to print the string “Hello World” on a Web page.

Install Plug-in

URL of the plug-in: https://www.aliyun.com/product/cloudtoolkit_en

The installation process of this Eclipse-based plug-in is similar to that of a common plug-in, and therefore will not be detailed here.

Configure the Plug-in Preferences

Top menu > Window > Preferences > Alibaba Cloud Toolkit > Accounts

When the following page is displayed, configure the AK and SK of your Alibaba Cloud account to complete the configuration of preferences.( If you are using a RAM user account, enter the AK and SK of the RAM user.)

Deploy the Application

In the Deployment Configurations dialog box, set the deployment parameters, and click Deploy to complete the initial deployment.

The /root/nodejs-demo/restart.sh file contains the following content:

source ~/.bash_profile
killall node
nohup node /root/nodejs-demo/helloworld.js > nohup.log 2>&1 &

Description of Deployment Parameters

  • Maven Build: If Maven is used to build the current project, you can use Alibaba Cloud Toolkit to directly build and deploy the application.
  • Upload File: If Maven is not used to build the current project, or a locally packaged deployment file already exists, you can select and directly upload the local deployment file.
  • Target Deploy ECS: Select a region from the drop-down list, and then select the ECS instance to be deployed in the region.
  • Deploy Location: Enter the deployment path on the ECS instance, for example, /root/nodejs-demo.
  • Command: Enter the application startup command, for example, sh /root/nodejs-demo/restart.sh. This parameter specifies the command to be executed after the deployment is completed. For a Node.js program, this is usually the startup command node XXX.js.
