How to install nodejs in CentOS ?

If you choose default yum install of nodejs you will get 6.x release which is very old.
To install latest version of nodejs in centos you can execute below command
Command 1

  
  	curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
   

You will get output as below

[vagrant@localhost ps-sinonjs]$ curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -

## Installing the NodeSource Node.js 14.x repo...


## Inspecting system...

+ rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release
+ uname -m

## Confirming "el7-x86_64" is supported...

+ curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_14.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm'

## Downloading release setup RPM...

+ mktemp
+ curl -sL -o '/tmp/tmp.KNA1QsAK2D' 'https://rpm.nodesource.com/pub_14.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm'

## Installing release setup RPM...

+ rpm -i --nosignature --force '/tmp/tmp.KNA1QsAK2D'

## Cleaning up...

+ rm -f '/tmp/tmp.KNA1QsAK2D'

## Checking for existing installations...

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

## Run `sudo yum install -y nodejs` to install Node.js 14.x and npm.
## You may also need development tools to build native addons:
     sudo yum install gcc-c++ make
## To install the Yarn package manager, run:
     curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
     sudo yum install yarn

Your main instructions are here

## Run `sudo yum install -y nodejs` to install Node.js 14.x and npm.
## You may also need development tools to build native addons:
     sudo yum install gcc-c++ make
## To install the Yarn package manager, run:
     curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
     sudo yum install yarn

I mean simply after executing command1 you can execute below commands and it will install latest Node.js version for you.

 sudo yum install -y nodejs 
 sudo yum install gcc-c++ make
 curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
 sudo yum install yarn
