I installed the bitcoin libraries on /mnt/volume_fra1_02, ran it via the following setting
bitcoind -datadir=/mnt/volume_fra1_02/.bitcoin -conf=/mnt/volume_fra1_02/.bitcoin/bitcoin.conf
i get an error when i want to create a new wallet
bitcoin-cli createwallet adminwallet
response : No authentication cookie could be found, and RPC password is not set. See -rpcpassword and -stdinrpcpass. Configuration file: (/root/.bitcoin/bitcoin.conf)
Probably still based on "/root/.bitcoin/bitcoin.conf" directory.
Could you help?
