Node.js is a JavaScript runtime environment based on the Chrome V8 engine. It is an open source, cross-platform JavaScript runtime environment. The application design language is Javascript. It is mainly used to build web servers and network applications. .
As Node.js is used more and more widely, how to deploy Node.js applications to the server has become a very hot topic. This article will introduce how to deploy a server using Node.js.
1. Choose a cloud computing service provider
How to choose a reliable cloud computing service provider is very important for deploying Node.js server. A good cloud service provider can help you Provide more stable and high-quality services. The following are some common cloud computing service providers:
AWS is one of the largest cloud service providers in the world, which provides A variety of computing and storage services, including EC2 instances, Lambda functions, S3 storage and RDS databases, etc.
AWS EC2 is an elastic cloud computing service that allows users to create and launch virtual machine instances and supports a variety of operating systems and applications, including Node.js.
Microsoft Azure is a cloud service platform launched by Microsoft, which provides services such as virtual machines, application services, and storage. Azure also allows users to use multiple programming languages and frameworks, including Node.js.
Google Cloud Platform is a cloud service platform provided by Google, which provides a variety of computing and storage services, including virtual machine instances, cloud storage and Database services, etc. Google Cloud Platform also supports Node.js.
2. Create a virtual machine instance
Before you start, you need to create a virtual machine instance on the cloud service provider's platform and install an operating system. When creating an instance, you need to choose an operating system and virtual machine type that are suitable for your Node.js application.
For example, when creating an instance on AWS EC2, you can choose operating systems such as Ubuntu, Red Hat, Windows, etc., and select instance types, such as t2.micro, t2.small, etc. Among them, t2.micro is the most basic instance type of AWS EC2 and is suitable for beginners.
3. Install and configure Node.js
After we create the virtual machine instance, we need to install the Node.js running environment in the virtual machine. Before installing Node.js, you need to install npm, which is a Node.js package manager that can easily install and manage Node.js modules.
The command to install npm is as follows:
sudo apt-get install npm
Then, you can install Node.js through the following command:
sudo apt-get install nodejs
After the installation is completed, you can check the Node.js through the following command Version:
node -v
It is very important to configure the development environment of Node.js. You can install the development tools through the following command:
sudo apt-get install build-essential
4. Deploy the application
After completing Node Once the .js is installed and configured, you can start deploying your applications by deploying them to the server. Here are some ways to deploy your application:
Deploying from source code is very simple, just upload the source code of your application to server and start running the application using the following command:
node app.js
PM2 is a process manager for Node.js that helps you manage and monitor Your Node.js application. Here are the steps to deploy a Node.js application using PM2:
PM2 can be installed with the following command:
npm install pm2 -g
Use the following command to start the application:
pm2 start app.js
Use the following command to monitor the application Running status:
pm2 monit
Use the following command to stop the application:
pm2 stop app.js
5. Summary
This article Introduces how to use Node.js to deploy servers, including steps such as selecting a cloud computing service provider, creating a virtual machine instance, installing and configuring Node.js, and deploying applications. Through these steps, you can easily deploy your Node.js application to the server and implement functions such as access and monitoring.
