Hi so I used the following bash script to set up bitcoin on my centos server https://gist.github.com/cdodd/f485b72aed8c2a6440a6141cd1ba8273?signup=true
however i don't know how to get a wallet or create a wallet and everytime i try I get the following error, their is no config file and I am not sure where one is meant to be located. could someone please help point me in the right direction to install bitcoin correctly and create my own wallet.
./bitcoin-cli -testnet getwalletinfo error: Could not locate RPC credentials. No authentication cookie could be found, and RPC password is not se t. See -rpcpassword and -stdinrpcpass. Configuration file: (/root/.bitcoin/bitcoin.conf)
