Try removing the rpcconnect line. rpcconnect is an option to bitcoin-cli, not bitcoind.

In fact, you can delete your bitcoin.conf entirely. bitcoind will create its own password if you don't set one (cookie), and bitcoin-cli can find it. All the other options are default. So I suggest just delete bitcoin.conf, restart bitcoind, and then try again.

I think I need to do something like [described here](https://bitcoin.stackexchange.com/questions/28107/bitcoin-is-not-connected-in-regtest-mode), do you think it's right?

I don't understand what the problem is for you. But no, that link doesn't help. bitcoin-cli fails to connect to your bitcoind entirely. That answer is about needing multiple nodes in your network before you can have all functionality.

(Asked by: username_0 on 2017-04-19)

This is what happens after I run this command `bitcoind --regtest --printtoconsole`, my guess is that it's something to do with bitcoin.conf

[![enter image description here](https://i.sstatic.net/b1cTr.jpg)](https://i.sstatic.net/b1cTr.jpg)

My bitcoin.conf file looks like this:

```
server=1
rpcuser=root
rpcpassword=password
rpcconnect=127.0.0.1
rpcport=8332

```

just do this...

To use bitcoind and bitcoin-cli, you will need to add a RPC password to your bitcoin.conf file. Both programs will read from the same file if both run on the same system as the same user, so any long random password will work:

```
  rpcpassword=change_this_to_a_long_random_password

```

in the future I'll be sure to [RTFM](https://bitcoin.org/en/developer-examples#testing-applications)
