Install Node-Red on Centos 7

It’s been a while since i have done anything with my ESP8266 development boards, so I’m now going to pick the back up and see what has changed.

One big change is the introduction of node-red on this page I’m going to go through the install process on Centos 7

1. 1. 1. once you have centos installed you will need to make sure it has been updated.

# sudo yum update -y

# sudo yum update -y

2. 1. install Extra Repositories

# sudo yum install epel-release -y

# sudo yum install epel-release -y

1. 3. install wget

# sudo yum install wget -y

# sudo yum install wget -y

1. 4. install Node.JS and npm

# sudo yum install nodejs

# sudo yum install nodejs

1. 5. install Node-Red

# sudo npm install -g node-red

# sudo npm install -g node-red

1. 6. Verify the Node.js and npm Installation

# node --version
v6.14.3
# npm --version
3.10.10

# node --version
v6.14.3
# npm --version
3.10.10

7. Install Service Script

sudo wget -O /etc/systemd/system/Node-Red.service https://raw.githubusercontent.com/ktndesai/Node-RED/master/Node-Red.service

sudo wget -O /etc/systemd/system/Node-Red.service https://raw.githubusercontent.com/ktndesai/Node-RED/master/Node-Red.service

for this i had to modify the script to point to the locations of node.js and node-red
the following 2 lines were changed in the file ” /etc/systemd/system/Node-Red.service”

ExecStart=/usr/bin/node $NODE_OPTIONS /lib/node_modules/node-red/red.js $NODE_RED_OPTIONS
WorkingDirectory=/root/.node-red/

ExecStart=/usr/bin/node $NODE_OPTIONS /lib/node_modules/node-red/red.js $NODE_RED_OPTIONS
WorkingDirectory=/root/.node-red/
