Simple and rude, first use xshell or other software to connect to the server
1. Download (the version here is modified according to the official website version)
wget https://npm.taobao.org/mirrors/node/v8.9.3/node-v8.9.3-linux-x64.tar.xz
2. Unzip
xz -d node-v8.9.3-linux-x64.tar.xz someone tar -xzvf node-v8.9.3-linux-x64.tar.gz
tar -xvf node-v8.9.3-linux-x64.tar
3. Configure environment variables (need to be executed in the root directory)
ln -s /root/node-v8.9.3-linux-x64/bin/node /usr/local/bin/node
ln -s /root/node-v8.9.3-linux-x64/bin/npm /usr/local/bin/npm
4. Check whether the installation is successful (if the correct version number appears, the installation is successful)
node -v
npm -v
Note: The download dependency of the lower version of npm is relatively slow. Use the following command to upgrade npm to the latest version
npm install -g npm
