How to manually upgrade the node version under CentOs

1. Find the corresponding nodejs package, refer to https://nodejs.org/download/release/

2. Switch to the location where node is installed, which is /usr/local/lib/nodejs

No existence can be established

mkdir /usr/local/lib/nodejs

3. Download

wget node-v8.12.0-linux-x64.tar.xz

4. Unzip

 tar -xJvf node-8.12.0-linux-x64.tar.xz -C /usr/local/lib/nodejs 
 mv /usr/local/lib/nodejs/node-8.12.0-linux /usr/local/lib/nodejs/node-8.12.0

5. Configure environment variables

vim ~/.profile

Enter the following

 export NODEJS_HOME=/usr/local/lib/nodejs/node-8.12.0/bin
 export PATH=$NODEJS_HOME:$PATH

6. Refresh environment variables immediately

~/.profile

7. Detection version

node -v

8. Establish system links to simplify calls

 sudo ln -s /usr/local/lib/nodejs/node-8.12.0/bin/node /usr/bin/node
 sudo ln -s /usr/local/lib/nodejs/node-8.12.0/bin/npm /usr/bin/npm
 sudo ln -s /usr/local/lib/nodejs/node-8.12.0/bin/npx /usr/bin/npx
