Download link : Node.js Chinese website
Modify the downloaded compressed package name as: nodejs.tar.xz
Switch to the directory where you want to install node and upload nodejs.tar.xz
cd usr/software

Download Node.js in this step, which can also be achieved by using wget
wget https://npm.taobao.org/mirrors/node/v11.7.0/node-v11.7.0-linux-x64.tar.xz
ps:
Linux wget is a tool for downloading files, used on the command line. It is an indispensable tool for Linux users, especially for network administrators, who often have to download some software or restore backups from a remote server to a local server. If we use a virtual host, we can only download from the remote server to our computer disk first, and then upload it to the server using the ftp tool. This is a waste of time and energy. But for Linux VPS, it can be downloaded directly to the server without going through the upload step. The wget tool is small in size but complete in function. It supports breakpoint download function, supports FTP and HTTP download methods, supports proxy server and is easy to set up and easy to
install.
yum -y install wget
1.2 Unzip nodejs.tar.xz and rename it
tar -xvf nodejs.tar.xz
mv node-v14.15.4-linux-x64 nodejs
1.3 Establishing a soft connection to become global
We see that the bin directory points to user/bin:
At this time, using node -v cannot display the version number of node, because the node command cannot be used globally, and a soft link needs to be established to make it global.
Global variables need to be configured under similar windows.
The bin directory of the unzipped file contains commands such as node and npm. We can use the ln command to set up the soft connection:
ln -s /usr/software/nodejs/bin/node /usr/bin/
ln -s /usr/software/nodejs/bin/npm /usr/bin/
After creation, it will point to /user/bin/node and /user/bin/npm;
1.4 Check whether the installation is successful
node -v
npm -v
Just see the version information displayed
