@krisklosterman I made your suggestion and when I run sudo systemctl status nodered.service it shows following respond

but http://localhost:1880; not respond , what did I miss

now its work

WorkingDirectory does not really have any effect, but the following works:
ExecStart=/usr/bin/node-red -u /home/pi/.node-red where the -u switch specifies the user working directory for Node-RED itself.

To Add to this script, running node-red as root is a bad idea, don´t do that

@papaiatis Assuming you User and Group to a non root user (for example the pi user) there is no reason to set the -u flag

When i only enter that...

wget -O /tmp/download https://gist.github.com/Belphemur/3f6d3bf211b0e8a18d93/download && sudo tar -zxf /tmp/download --strip-components 1 -C /etc/systemd/system/

..i get that error at the end:

gzip: stdin has more than one entry--rest ignored
tar: Child returned status 2
tar: Error is not recoverable: exiting now

Why that?

Problem is HERE:

root@debian-influx:~/.node-red# tar -zxf /tmp/download --strip-components 1 -C /etc/systemd/system/gzip: stdin has more than one entry--rest ignored
tar: Child returned status 2
tar: Error is not recoverable: exiting now

The /tmp/download is a zip file, not a gzip file. On my Ubuntu system

sudo apt install unzip

wget -O /tmp/download https://gist.github.com/Belphemur/3f6d3bf211b0e8a18d93/download

unzip /tmp/download

Now edit the 3f6d3bf211b0e8a18d93-master/Node-RED.service file and make any changes you like as per the prior posts here.
