I am doing something really dumb but can't figure it out.  
I need to run numerous instances of Node-Red. As such, I have under my /home/myusername 2 folders "nr1" and "nr2".  
I have run npm i node-red in each of those sub folders and it installs node-red.  
In each of those, I have modified the settings.js file to set the ports to 1880 and 1881 as well as the home directory to be /home/myusername/nr1 and nr2.

So, if I manually issue /usr/bin/node /home/myusername/nr1/node\_modules/node-red/red.js Node-Red fires right up.  
Now here is the problem. I want to start these via systemd. So, I have created a "nr1.service" file with the following information:

[Unit]  
Description=Node-Red for NR1  
Documentation=[Documentation : Node-RED](http://nodered.org/docs)  
After=syslog.target network.target

[Service]  
Type=simple  
ExecStart=/usr/bin/node /home/administrator/nr1/node\_modules/node-red/red.js  
WorkingDirectory=/home/administrator/nr1  
Nice=10  
Restart=on-failure  
KillSignal=SIGINT  
ProtectSystem=full

[Install]  
WantedBy=multi-user.target

When I try to start the service, it says permission denied on /home/nr1. I checked my settings file and I did have that in there (was a typo). I have since changed it to be /home/myusername/nr1/ but that does not solve things.

Any ideas as to what I am doing wrong?

Hi, been a long day today for me so I can't quite focus on what might be wrong. However, if you check out my alternate installer on GitHub, it contains an annotated example service file that might help.

You also need

```auto
User=administrator
Group=administrator

```

or whatever user/group you want to run the service as.

Everyone was close.  
Coming from a windows world to linux, remember to check your typing.

I had a small typo in my settings.js file that was goofing things up.
