HomeWeb Front-endFront-end Q&Aweb server deployment nodejs

As a popular back-end development language, Node.js has become increasingly popular in recent years. Node.js uses an event-driven, non-blocking I/O model that provides excellent performance when handling large numbers of concurrent requests. Therefore, it has become the choice of many Internet companies.

In practical applications, deploying Node.js applications to production environments is an important topic. Deploying a Node.js application involves selecting an appropriate server, configuring the server environment, installing Node.js, and publishing the application. This article will introduce how to deploy Node.js applications on CentOS 7 systems.

Step 1: Select a server

The first step in deploying a Node.js application is to select a server. In CentOS 7 systems, Nginx is a popular web server that can reverse proxy requests to Node.js applications. Therefore, when choosing a server, consider using an Nginx-based system.

In server selection, the hardware configuration and performance of the server also need to be considered. Depending on the application's expected load and traffic, choosing an appropriate server will ensure the stability and reliability of the application. At the same time, the scalability of the server also needs to be considered so that it can be upgraded later according to actual needs.

Step 2: Configure the server environment

After selecting the server, you need to configure the server environment. In CentOS 7 systems, you can install necessary software and tools through the yum command.

First, you need to install Node.js and npm. The command is as follows:

yum install -y nodejs
yum install -y npm

Then, you need to install pm2, which is a Node.js process manager that can restart the application when the application crashes, and can also perform load balancing and monitoring operations. The command is as follows:

npm install pm2 -g

Next, you need to install Git. In future application releases, Git can be used for code management and version control. The command is as follows:

yum install -y git

Finally, Nginx needs to be installed. Nginx is a high-performance web server that can reverse proxy requests to Node.js applications. The command is as follows:

yum install -y epel-release
yum install -y nginx
systemctl start nginx

After the installation is complete, you can test whether Nginx is running normally by accessing the server's IP address.

Step 3: Deploy the application

After configuring the server environment, you need to deploy the Node.js application to the server.

1. Clone the code

Enter the ~/ directory and use Git to clone the application code. The command is as follows:

cd ~
git clone <应用代码仓库地址>

2. Install dependencies

Enter the application directory , use npm to install application dependencies, the command is as follows:

cd <应用目录>
npm install

3. Start the application

Use pm2 to start the application, the command is as follows:

pm2 start <应用入口文件>

4. Configure Nginx

Finally, Nginx needs to be configured to reverse proxy the request to the Node.js application.

First, back up the default configuration file of Nginx, the command is as follows:

mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak

Then, create a new Nginx configuration file, the command is as follows:

vi /etc/nginx/nginx.conf

Add the following to the configuration file Content:

http {
    upstream <应用名称> {
        server 127.0.0.1:<应用端口>;
        keepalive 64;
    }

    server {
        listen       80;
        server_name  <应用域名>;

        location / {
            proxy_http_version 1.1;
            proxy_set_header Connection "";
            proxy_pass http://<应用名称>;
        }
    }
}

Among them, and are the name and port number of the application respectively, and is the domain name accessed by the application. It needs to be replaced according to the actual situation.

Finally, restart the Nginx service to make the configuration take effect. The command is as follows:

systemctl restart nginx

Now, the Node.js application has been successfully deployed to the server. You can access the application through , and you can also use pm2 to monitor and manage the application.

Summary

To deploy a Node.js application to a server, you need to select a suitable server, configure the server environment, install Node.js, install pm2, install Git, and configure Nginx. This article gives detailed steps for deploying Node.js applications on CentOS 7 systems. I hope it will be helpful to readers.

React: The Foundation for Modern Frontend DevelopmentReact: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AM

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

React: A Powerful Tool for Building UI ComponentsReact: A Powerful Tool for Building UI ComponentsApr 19, 2025 am 12:22 AM

React is a JavaScript library for building user interfaces. Its core idea is to build UI through componentization. 1. Components are the basic unit of React, encapsulating UI logic and styles. 2. Virtual DOM and state management are the key to component work, and state is updated through setState. 3. The life cycle includes three stages: mount, update and uninstall. The performance can be optimized using reasonably. 4. Use useState and ContextAPI to manage state, improve component reusability and global state management. 5. Common errors include improper status updates and performance issues, which can be debugged through ReactDevTools. 6. Performance optimization suggestions include using memo, avoiding unnecessary re-rendering, and using us

Using React with HTML: Rendering Components and DataUsing React with HTML: Rendering Components and DataApr 19, 2025 am 12:19 AM

Using HTML to render components and data in React can be achieved through the following steps: Using JSX syntax: React uses JSX syntax to embed HTML structures into JavaScript code, and operates the DOM after compilation. Components are combined with HTML: React components pass data through props and dynamically generate HTML content, such as. Data flow management: React's data flow is one-way, passed from the parent component to the child component, ensuring that the data flow is controllable, such as App components passing name to Greeting. Basic usage example: Use map function to render a list, you need to add a key attribute, such as rendering a fruit list. Advanced usage example: Use the useState hook to manage state and implement dynamics
