The central server is the core network device of many organizations and needs to run various applications and scripts, including Node.js. Node.js is an open source, cross-platform, fast and scalable JavaScript runtime environment. This article will introduce you how to install Node.js on CentOS.

Step 1: Update the system

Before installing Node.js, you first need to ensure that the system has been updated to the latest version. Update the system using the following command:

sudo yum update

After completing the update, reboot the system for the changes to take effect.

Step Two: Install Node.js Dependencies

Node.js requires some local dependencies to function properly. Install these dependencies using the following command:

sudo yum install curl gcc-c++ make

Step Three: Install Node.js

To install Node.js on CentOS, it is best to use the NodeSource repository. Use the following command to add the NodeSource repository to the CentOS system:

curl -sL https://rpm.nodesource.com/setup_14.x | sudo -E bash –

Please note that in the above command, we are using the Node.js 14.x version, you can change it by replacing "14" with other version number to install other versions.

Next, install Node.js using the following command:

sudo yum install nodejs

Once the installation is complete, verify that Node.js has been installed correctly by running the following command:

node -v

If All goes well and you should see the version information for Node.js.

Step 4: Install NPM

NPM (Node Package Manager) is a package manager that is used to install and manage Node.js software packages. NPM is automatically installed when installing Node.js on CentOS.

To verify that NPM has been installed correctly, run the following command:

npm -v

If all goes well, you will see the version information of NPM.

Step 5: Using Node.js

You have now successfully installed Node.js. To run a Node.js server or execute a Node.js script, run the following command:

node script.js 或 node server.js

Note that in this example, "script.js" and "server.js" are the ones you want to run. The name of the script and server. Make sure to upload npm packages to the server before running them.

Summary

Node.js is a very popular JavaScript runtime environment that developers can use to build a variety of applications and scripts. This article shows you how to easily install Node.js on CentOS and run tasks with it. You should now have successfully installed Node.js and be ready for the next step.

HTML and React's Integration: A Practical GuideApr 21, 2025 am 12:16 AM

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React and HTML: Rendering Data and Handling EventsApr 20, 2025 am 12:21 AM

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

The Backend Connection: How React Interacts with ServersApr 20, 2025 am 12:19 AM

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React: Focusing on the User Interface (Frontend)Apr 20, 2025 am 12:18 AM

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React in the HTML: Building Interactive User InterfacesApr 20, 2025 am 12:05 AM

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React: 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.

The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AM

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.
