yum install nodejs configuration

Under Linux systems, Node.js is a very popular runtime environment that is often used to build web applications and server-side applications. For some novices, it is still a bit difficult to install Node.js under Linux, but the method of using the yum command to install Node.js is relatively simple. In this article, we will introduce how to use the yum command to install Node.js and perform simple configuration.

1. Install Node.js

Before starting to install Node.js, it is recommended to upgrade the system software package to ensure the security and stability of the system. Enter the following command in the terminal:

sudo yum update

After the update is completed, enter the following command to install Node.js:

sudo yum install nodejs

2. Verify the installation

After the installation is completed, you can Use the following command to verify successful installation:

node -v

If the version number is displayed, Node.js has been successfully installed.

3. Install npm

npm is the package management tool for Node.js, which can be used to download and manage Node.js modules. Enter the following command in the terminal to install npm:

sudo yum install npm

After the installation is complete, you can use the following command to verify whether the installation is successful:

npm -v

If the version number is displayed, npm has been successfully installed.

4. Configure npm mirror

Since the default download speed of npm is slow, we can configure the npm mirror to speed up the download speed. Use the following command to configure the npm image:

npm config set registry https://registry.npm.taobao.org

After running the above command, npm will use the Taobao image to download, and the download speed will be greatly improved.

5. Use Node.js

After the installation is complete, you can use npm to install and manage the Node.js module. Suppose we need to install the express module, we can use the following command to install it:

npm install express

Similarly, we can also use npm to uninstall the Node.js module:

npm uninstall express

Enter node in the terminal , you can enter the interactive environment of Node.js, and you can use JavaScript to write and run programs. For example:

$ node
> console.log('Hello, world!');
Hello, world!

Use the command CTRL C to exit the Node.js interactive environment.

6. Summary

Through the above steps, we can use the yum command to easily install and configure Node.js, and use npm to manage Node.js modules. I hope this tutorial can help you solve the problem of installing and configuring Node.js.
