How to install node. js and express in CentOS Linux, centosnode. js

Preface

Recently, we need to install and use node. js and express because of work requirements. However, I have found many steps and various problems on the Internet, so I 'd like to summarize them myself.

1. Download

wget --no-check-certificate https://nodejs.org/dist/v6.10.1/node-v6.10.1-linux-x64.tar.xz

2. Decompress

tar xvf node-v6.10.1-linux-x64.tar.xz

Node and npm already exist in the bin folder and are set to global.

 sudo ln -s /data/node-v6.10.1-linux-x64/bin/node /usr/local/bin/node sudo ln -s /data/node-v6.10.1-linux-x64/bin/npm /usr/local/bin/npm

3. Install express

npm install express -gd npm install -g express-generator

Set express to global:sudo ln -s /data/node-v6.10.1-linux-x64/bin/express/usr/local/bin/express

4. Successful

express --version

5. npm start in the project

Enter 127.0.0.1: 3000 in the browser

Welcome to express!

If not, check the Firewall:

Modify/etc/sysconfig/iptables File to add the following content:

In-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPTAdd

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3000 -j ACCEPT

Open the firewall to port 3000.

6. Successful again!
