[Guide] Futurebit Apollo BTC Custom Linux Install - Node

[n0nce]

Hi N0nce,

I followed the steps you outlined to install bitcoin-cli.  Doesn't appear to have worked, unfortunately.  I am getting the same error after installation in the debug file and when I ran bitcoin-cli echo 'hello world', I got the following:

error: Could not locate RPC credentials. No authentication cookie could be found, and RPC password is not set.  See -rpcpassword and -stdinrpcpass.  Configuration file: (/home/futurebit/.bitcoin/bitcoin.conf)

I'm thinking I don't actually have bitcoin-cli installed as when I entered the command sudo install -m 0755 -o root -g root -t /usr/local/bin bin/bitcoin-cli, the command line simply reloaded to the base user and nothing was communicated about installation.

No, no, that all looks good. It just means Bitcoin Core is running as a different user. I get that when running bitcoin-cli as a different user than the actual Bitcoin Core bitcoind daemon.

I seriously hope it isn't the case, but it is possible that on default Futurebit OS, Core runs as root. To verify, try sudo bitcoin-cli getinfo.

If my suspicion holds true, you would need to create RPC credentials like the error message suggests.

Ran it, here is the result

error: Could not locate RPC credentials. No authentication cookie could be found, and RPC password is not set.  See -rpcpassword and -stdinrpcpass.  Configuration file: (/root/.bitcoin/bitcoin.conf)

Here is how to create RPC credentials:

Code:

git clone https://github.com/bitcoin/bitcoin.git
cd bitcoin
git checkout v23.0
cd share/rpcauth/
python3 rpcauth.py the_username_of_the_user_you_want cleartext_password_unique_long

It will output a hash that you want to store (e.g. in a text file) for the very last step. You can trash that afterwards.

Then delete shell history:

Code:

history -c
history -w

Finally add this line to the Bitcoin configuration file (in your case at /root/.bitcoin/bitcoin.conf)

Code:

rpcauth=the_username_of_the_user_you_want:hash_that_you_had_to_store_for_this_step

After these changes, reboot Apollo and cross fingers
You should be able to access bitcoin-cli from any user now, as long as you specify -rpcuser=<user> -rpcpassword=<password>.

Lightning will need to know those parameters as well, though.
Add to lightningd.conf and reboot again:

Code:

--bitcoin-rpcuser <user>
--bitcoin-rpcpassword <password>
