I've successfully setup and running cardano node from terminal. Now I've setup cardano node to run as service(systemd, Ubuntu) so that I don't have to run the command all the time and have a terminal always open. From journalctl log all looks good, and I have check tip is reached using explorer.cardano.org. However, I now get error when using cardano-cli and I cannot figure out why...

Cardano-cli error message

  1. Stop using root (for interactive as well as systemd startup user), it's a terrible idea to run applications
  2. You cannot (*should not) run something as another user and point to paths in your own $HOME folder, this will more often than not only lead you to permission errors.
  3. I assume node.socket= was a typo, if not - your start command does not match $CARDANO_NODE_SOCKET_PATH environment variable.

While you can now address the state by recursively fixing permissions, you've likely populated environment variables, build caches, profiles, etc across a mix of root and toby user, you might want to start from scratch and not run anything to do with cardano-node.

  • 0. Thanks for the reply! 1. Okay, I am no linux expert:) I just followed some tutorial online, however I saw that there were some cardano tutorials that created an own user for cardano node. I will look into that. 2. Noted. 3. This was actually not a typo. I found this a bit weird, because I could not recall the socket filename had an = when running command line directly. However, now I don't understand why I do not get a "cannot find socket" error instead... My $CARDANO_NODE_SOCKET_PATH points to a file without the =

  • If there are online tutorials using root, I think it's potentially good to highlight bad practices to them (if they've a way to contact on their pages). About 3, if it wasnt a typo, then perhaps one of your earlier attempts to run cardano-node may have accidentally had an = sign after socket. Once you stop all instances of node running, you should be alright

  • Okay, I will try to delete the db folder and have a new go for scratch. Thanks for the input @RdLrT!
