Node.js has gained immense popularity among developers due to its efficient and scalable nature when it comes to building fast, real-time web applications. If you're planning to deploy a Node.js application on a Centos 7 server, you've come to the right place. In this article, we'll guide you through the step-by-step process of installing Node.js on Centos 7, ensuring a smooth and hassle-free deployment experience.

Centos 7 is a widely used and highly reliable Linux distribution that provides a stable and secure platform for running web servers. It offers excellent compatibility for Node.js, making it an ideal choice for hosting Node.js applications. Before we dive into the installation process, let's quickly introduce Node.js and its benefits.

Node.js is an open-source, cross-platform JavaScript runtime environment built on Chrome's V8 JavaScript engine. It allows developers to execute JavaScript code outside of a web browser, enabling server-side scripting and building powerful networking applications. Its event-driven, non-blocking I/O model makes it highly efficient and perfect for real-time and scalable applications.

Now, let's get started with the installation process.

Step 1: Update the Operating System

Before installing Node.js, it is crucial to ensure that your Centos 7 server is up to date. Open a terminal and run the following commands:

```

sudo yum update

```

This command will update all the installed packages on your Centos 7 server, ensuring a secure and stable environment for Node.js installation.

Step 2: Install Node.js using Node Version Manager (NVM)

To simplify the installation process and manage multiple Node.js versions, we'll use Node Version Manager (NVM). NVM allows you to easily switch between different Node.js versions and manage the associated packages.

Start by downloading and installing NVM by executing the following commands:

```

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

```

Once the installation is complete, close and reopen the terminal to ensure that NVM is properly configured.

Step 3: Install Node.js using NVM

After installing NVM, we can proceed to install the desired version of Node.js. To list all available versions, use the following command:

```

nvm ls-remote

```

Select the version you wish to install, such as the latest LTS version or a specific version. For example, to install the latest stable LTS version, execute the following command:

```

nvm install --lts

```

This command will download and install the specified version of Node.js. After the installation is complete, you can verify the installed version by running:

```

node -v

```

Step 4: Configuring Node.js Environment

To ensure that Node.js is readily available in your environment, you need to configure the environment variables. This can be done by adding the following lines to your ~/.bashrc file:

```

export NVM_DIR="$HOME/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

```

Save the changes and apply the modifications by running the following command:

```

source ~/.bashrc

```

This will configure the necessary environment variables, ensuring that Node.js is accessible from anywhere on your Centos 7 server.

Step 5: Verifying the Installation

To ensure that Node.js is successfully installed and accessible, you can check the installed version using the following command:

```

node -v

```

This should display the version number you installed earlier, confirming a successful installation.

Congratulations! You have now successfully installed Node.js on your Centos 7 server. You are now ready to deploy and run your Node.js applications on this platform. Node.js offers excellent compatibility with Centos 7 and provides a stable and efficient runtime environment.

As you continue building and deploying your Node.js applications, it's recommended to keep your Node.js version up to date. NVM makes it incredibly easy to switch between different versions and update Node.js as new versions are released.

In conclusion, installing Node.js on Centos 7 doesn't have to be a complex task. By following these steps and utilizing the power of NVM, you can simplify the deployment process and enjoy the benefits of Node.js in your projects. Get started today and harness the power of Node.js on your Centos 7 server.
