Install a Node.js service for systemctl on CentOS 7

my-service.service

#Type=forking

WantedBy=multi-user.target

node-daemon.sh

#! /bin/bash

curl -sL https://rpm.nodesource.com/setup | bash -
yum install -y nodejs gcc-c++ make

sudo mkdir -p /var/node/my-service/
# ... cp project into /var/node/my-service/

cd /var/node/my-service/
npm install
sudo cp my-service.service /etc/systemd/system/
systemctl enable my-service
systemctl start my-service.service

I’m doing a similar thing actually and I thought enable would start the service (which will start the js script), but maybe I need to add the start command as well, cuz I can see that the service is enabled but the script doesn’t seem to start 🤪
