The hack to store node-red logs in linux distribution systems just follow the below steps:-

1. Create a custom node-red service in /etc/systemd/system/ Command to make a .service file nano /etc/systemd/system/node-red-custom.service

   [Unit]
   Description=Node-RED is a tool for wiring together hardware devices, APIs and online services in new and interesting ways.
   After=syslog.target network.target
   Documentation=http://nodered.org/
   
   [Service]
   #Full Path to Node.js
   ExecStart=  /usr/bin/node-red
   WorkingDirectory=/root/node-red/
   # User/Group that launches node-RED (it's advised to create a new user for Node-RED)
   # You can do : sudo useradd node-red
   # then change the User=root by User=node-red
   User=root
   Group=root
   Nice=10
   #SyslogIdentifier=Node-RED
   SyslogIdentifier=node-red-custom
   StandardOutput=syslog
   StandardError=syslog
   # Make Node-RED restart if it fails
   Restart=on-failure
   # Node-RED need a SIGINT to be notified to stop
   KillSignal=SIGINT
   
   [Install]
   WantedBy=multi-user.target
   

   2.Make configuration file which targets where do you want to store the logs

   nano /etc/rsyslog.d/node-red-custom.conf

   if $programname == 'node-red-custom' then /var/log/node-red-logs.log
   & stop
   

after creating these two file please run below commands

sudo systemctl restart rsyslog
sudo systemctl enable node-red-custom.service
sudo systemctl start node-red-custom.service

Now your custom node-red service start storing logs in /var/log/node-red-logs.log

Note:- You must kill the running node-red service before enable the custom node-red service as mentioned above.
