1、通過官方查詢需要安裝的版本
https://github.com/nodesource/distributions
2、在CentOS下獲取相應版本的nodejs資源（以NodeJS 14.x為例）
粘貼 curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
3、運行 sudo yum install -y nodejs 進行nodejs安裝
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
4、確認安裝成功
node -v
npm -v
