How to Install and Upgrade Node.js on Red Hat 7

Installing Node.js on a Red Hat 7 system is a relatively straightforward process that involves adding a repository and running a few commands. In this article, we will guide you through the steps of installing and upgrading Node.js using the 'yum' package manager utility.

Remove Existing Versions

Before installing a new version of Node.js, it's recommended to remove any existing versions installed on your system. Run the following command as root:

```

sudo yum remove -y nodejs npm

```

Check if Node.js is Already Installed

Run the following command to check if Node.js is already installed and what its current version is:

```

rpm -qa 'node|npm' | grep -v nodesource

```

If the output shows that Node.js is already installed, you can proceed with upgrading it. Otherwise, continue with installing a new version.

Install NodeSource Repository

To install the latest version of Node.js, we need to add the NodeSource repository to our system. Run the following command as root:

```

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

```

This command downloads and executes the 'setup_12.x' script using bash.

Upgrade to Latest Version

Once the repository is installed, you can upgrade Node.js to the latest version by running the following command as root:

```

sudo yum install -y nodejs

```

Verify Installation

To verify that Node.js has been successfully installed and upgraded, run the following command:

```

node -version

```

This should display the current version of Node.js.

In conclusion, upgrading to the latest version of Node.js on a Red Hat 7 system is a simple process that involves adding a repository and running a few commands. By following these steps, you can ensure that your system has the latest and most secure version of Node.js installed.
