How to install Node.js in Cenos7

Node.js is a development platform for building high-performance web applications using JavaScript. Created by Ryan Dahl in 2009, it uses an event-driven, non-blocking I/O model, allowing it to easily handle large numbers of concurrent connections.

Cenos7 is a popular Linux operating system with rich features and excellent performance, so it is often used to build high-performance network applications. In this article, we will explain how to install Node.js in Cenos7.

Step 1: Install Node.js

There are several different methods you can use to install Node.js in Cenos7. The quickest and recommended way is to install it using the NodeSource plugin. By default, the Node.js version provided in CentOS's package manager may be too old to meet your needs.

1.1: Install the EPEL repository

Before you begin, the first step is to install the EPEL repository. The EPEL repository provides a large number of extra packages for CentOS that are usually not available in the default CentOS repository. In many cases, NodeSource plugins depend on the EPEL repository. To install the EPEL repository, you can use the following command:

sudo yum install epel-release

1.2: Install the NodeSource plugin

After installing the EPEL repository, we can now proceed to install the NodeSource plugin. This is a special pre-compiled package that makes it easy to install Node.js.

To install the NodeSource plug-in, open a terminal and execute the following command:

curl -sL https://rpm.nodesource.com/setup_12.x | sudo bash -

This command will download and run the script setup_12.x from the NodeSource official site, which adds the NodeSource repository to the system .

1.3: Install Node.js

After installing the NodeSource plugin, use the following command to install Node.js in Cenos7:

sudo yum install nodejs

This command will download and install Node. js binary package and its dependencies. At this point, your Cenos7 system has the latest Node.js version installed.

Step 2: Verify Node.js

After installing Node.js, let us execute the following command to verify that it was installed correctly:

node -v

If everything goes well, the command will return Current Node.js version. This means that Node.js has been successfully installed on the Cenos7 system.

Step 3: Install npm

Npm is a package manager for Node.js that makes it easy to install and manage dependencies for any Node.js application. To install npm on Cenos7, use the following command:

sudo yum install npm

This command will download and install npm and its dependencies. After the installation is complete, you can use the following command to verify that npm is installed correctly:

npm -v

If all goes well, the command will return the current version of npm and you have successfully installed Node.js and npm on Cenos7.

Conclusion

In this article, we introduced how to install Node.js on Cenos7 and manage its version using the NodeSource plugin. Node.js is an excellent platform for building high-performance web applications, and CentOS is an excellent Linux operating system for building and managing these web applications. Therefore, by installing Node.js and npm, you can get the best performance from your CentOS architecture and manage and manage your Node.js applications more efficiently.
