Node.js is a JavaScript runtime environment that allows developers to run JavaScript code on the server-side. It provides an event-driven architecture and a non-blocking I/O model, making it highly efficient for building scalable and real-time applications. In this tutorial, we will walk you through the steps to install Node.js on CentOS 7.
Before installing Node.js, it is recommended to update the system packages to their latest versions. Open the terminal and run the following command:
sudo yum update -y
To install the latest version of Node.js, we will enable the Node.js Yum repository on our CentOS system. Run the following command to enable the Node.js Yum repository:
sudo curl -sL https://rpm.nodesource.com/setup_15.x | sudo bash -
After enabling the Node.js Yum repository, we can install Node.js and its package manager (npm) using the following command:
sudo yum install nodejs
Once the installation is complete, you can verify the version of Node.js and npm by running the following commands:
node -v
npm -v
If the installation is successful, you will see the version numbers for Node.js and npm printed on the terminal.
Congratulations! You have successfully installed Node.js on your CentOS 7 system. Now you can start building scalable and efficient applications using Node.js.
