Request for help using regest

[stevebc]

I'm attempting to use regtest as in this tutorial:
https://bitcoin.org/en/developer-examples

When I issue this:
bitcoin-cli -regtest generate 101

I get a failure:
'you must set rpcpassword=<password> in the configuration file:
/home/ubuntu/.bitcoin/bitcoin.conf'

I add that file and instead get the error:
'incorrect rpcuser or rpcpassword (authorization failed)'

Do I need particular rpcuser/rpcpassword values in order to use regtest?  Any suggestions as to what I may have missed?

Thanks

You need to first start Bitcoind or bitcoin-qt in regtest mode. Start bitcoin-qt with the server option. When doing so, make sure that bitcoin.conf has an rpcuser and rpcpassword set. It doesn't matter what they are, as long as they exist.
