Today, the editor will share with you the relevant knowledge points about how to deploy nodejs in Centos. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Install node and npm

Download the compiled node package from the official website:

Wget https://nodejs.org/dist/v6.10.2/node-v6.10.2-linux-x86.tar.xzxz-d node-v6.10.2-linux-x86.tar.xztar-xf node-v6.10.2-linux-x86.tar

Unzip it to get the node-v6.10.2-linux-x86 folder, which contains a bin directory that contains the node and npm we need.

It should be noted here that npm is linked to.. / lib/node_modules/npm/bin/npm-cli.js and cannot be copied directly to / usr/bin/, otherwise there will be errors, which can be seen using ll.

Fill in the ip address of the server in the a record of the domain name and wait for it to take effect.

Then through the domain name direct access, found that can not access our program, because the default access port is 80, and we listen to the port is 8080. Here you can pass:
