Cardano-node: Missing protocolMagicId

Staking & Delegation Setup a Stake Pool
#8

cardano-node run --topology /home/cardano/cnode/config/mainnet-topology.json --database-path /home/cardano/cnode/db --socket-path /home/cardano/cnode/sockets/node.socket --host-addr 0.0.0.0 --port 3001 --config /home/cardano/cnode/config/mainnet-config.json

The screenshot is wrong, later I fixed that

This was my command, I think it’s ok, I have the config file in /home/cardano/cnode/config/mainnet-config.json

but still giving me protocolmagicid error

#9

So then download the alonsoGenesis json file into config folder and start again…

#10

I installed alonzo genesis mainnet and testnet but still giving me protocolmagicid error

In the documentation there are 1 file that I don’t know if I used or not
problema_04_03

#12

so, please remove everything from db folder again, and start again:
rm -rf /home/cardano/cnode/db/* if does not help then maybe you will create that file manually…

#13

now something changed but still giving me error I think
problema_04_04

Let me guess, new topic?

#14

wow - that is an error indeed - what is the content of the db folder now?
ls -la /home/cardano/cnode/db/

#15

total 8
drwxrwxr-x 2 cardano cardano 4096 jun 1 14:34 .
drwxrwxr-x 8 cardano cardano 4096 may 27 17:29 …
this is the content

#16

hmm cardano user is the owner of folder, but your user is is alberto…
I think time to remove the db folder itself:
sudo rm -rf /home/cardano/cnode/db
then create it again
mkdir /home/cardano/cnode/db
then check the owner - should be alberto - ls -la /home/cardano/cnode/db

if yes, start again

I get permission denied all the time, is there any way to remove the permissions and not have to put sudo su to modify the cardano folder?

#18

total 8
drwxr-xr-x 2 root root 4096 jun 1 14:50 .
drwxrwxr-x 8 cardano cardano 4096 jun 1 14:50 …

The owner it’s not alberto

#19

yes - I dont know where this cardano user came from, but you can modify the ownership the folder by:
sudo chown -R alberto:alberto /home/cardano/cnode

WAIT!

just realized then you are operating everything in home folder of cardano user… probably better to switch the user to cardano from alberto!

RUNNING! thank you very much
Running_01

Now I have some questions, the port will always be 3001? and which host should I put to launch a token to the mainnet?

How can I stop the node?

Thanks for the help it is really much appreciated, cardano has a good community

#21

So - which guide you followed?

I dont understand this - but go through again on this:
https://docs.cardano.org/projects/cardano-node/en/latest/stake-pool-operations/getConfigFiles_AND_Connect.html
and once you can query the tip, then you can use cardano-cli to mint a token

#22

Okay thank you very much for helping me with @raph_cardano I really apreciate it

#23

ok, keep in mind that the node should be fully synced to able to mint.

#24

You’re welcome :pray: happy @laplasz found the root cause

#25

@berthom
I am facing the same error message but I am already logged in as the user which owns the folders. Did you correct the error by simply changing users or was it something else? I notice your user did not change (alberto-). I think this is because alberto- is not the actual user – it is the name of the server/cpu you are using. Please advise. Thank you

#26

Disregard. I have corrected mine by placing the db folder in the same folder as the 4 json files.

#27

Oh, ok, great :+1:
