Setup secondary Relay

Did you just copy and paste what was written in the coincashew you manual? You should at lest try to understand what you are doing and how the different parts play together.

You made a cardano-node.service file which you deploy with systemd with

sudo systemctl start cardano-node

in that file, in line 11, as it says in the log message you have the start up script mentioned. And systemd could not find the cardano-nodecommand in that script. That could mean your PATH env variable is not set right or your cardano-node executable doesnt exist or at least not where it is supposed to exist.

what does

cardano-node version

give you?

cardano-node 1.25.1 - linux-x86_64 - ghc-8.10
git rev 9a7331cce5e8bc0ea9c6bfa1c28773f4c5a7000f

WorkingDirectory= xxxx/cardano-my-node
ExecStart = /bin/bash -c ‘xxxx/cardano-my-node/startBlockProducingNode.sh’

the bin bash should be the line 11, not sure what is wrong tho

sometimes systemd has other environment variables but it is hard to say that from here… with some googling you should be able to figure that out

What should I google?
