linux centos7 64 bit build node environment
Run node -v if an error is reported bash: ./node: cannot execute binary file
It may be that the downloaded node version is wrong, please check whether it is the linux centos7 64-bit version of node
Install node as follows :
(Because it is a test environment, I first cd to the /home/greatwall folder, and then execute the following command)
1、wget https://nodejs.org/dist/v8.11.1/node-v8.11.1-linux-x64.tar.xz
2、xz -d node-v8.11.1-linux-x64.tar.xz
3. ls (execute this command and you will find that the package name is node-v8.11.1-linux-x64.tar)
4、tar -xvf node-v8.11.1-linux-x64.tar
5, cd node-v8.11.1-linux-x64 / bin
6. Execute the pwd command to view the current directory as /home/greatwall/node/node-v8.11.1-linux-x64/bin
7. Execute the following two commands to install soft connection
ln -s /home/greatwall/node/node-v8.11.1-linux-x64/bin/node /usr/sbin/node
ln -s /home/greatwall/node/node-v8.11.1-linux-x64/bin/npm /usr/sbin/npm
(The execution of the above command may be because the folder does not exist, the operation is as follows: a new window needs to be opened)
