Accessing Node-RED flow file

In case you encounter issues with Node-Red configuration, making Node-RED UI unreachable (e.g. infinite loop that consume all node CPU) and you have no backup file:

• You may directly connect on the box using the node-red user (password is the one you use to connect on ThingPark Enterprise All-in-One):

  ssh node-red@$BOX_IP

• Enter the node-red-data folder:

  cd $ROOTACT/node-red-data/

• You can edit flows.json and correct the file.

• You can now kill -9 the node-red process, it will be automatically restarted, take care to only kill the "node-red" process:

  am335x-evm:~$ ps | grep node-red
  3768 root      1464 S    {S99node-red} /bin/sh /etc/rc5.d/S99node-red _respawnService
