I am really sorry, please teach. Please tell me the procedure for installing bitcoin full node in CUI on CentOS. Currently I installed using the following procedure, but I got an error in RPC authentication.

1. $ sudo yum install wget

2. $ sudo wget https://bitcoin.org/bin/bitcoin-core-0.17.1/bitcoin-0.17.1-x86_64-linux-gnu.tar.gz

3. $ sudo wget https://bitcoin.org/bin/bitcoin-core-0.17.1/SHA256SUMS.asc

4. $ sudo wget https://bitcoin.org/laanwj-releases.asc

5. $ sudo gpg --import laanwj-releases.asc

6. $ sudo tar -zxvf bitcoin-0.17.1-x86_64-linux-gnu.tar.gz

7. $ sudo install -m 0755 -o USER_NAME -g root -t /usr/local/bin bitcoin-0.17.1/bin/*

8. $ mkdir ~/.bitcoin

9. $ vi ~/.bitcoin/bitcoin.conf

  1. Enter the following with vi and save.
mainnet = 1
txindex = 1
server = 1
rest = 1
rpcuser = a
rpcpassword = a
rpcport = 8332

11. $ cd /DATA_DIR

12. $ sudo mkdir bitcoin

13. $ sudo chmod -R 777 bitcoin/

14. $ bitcoind -daemon -datadir=/DATA_DIR/bitcoin -conf=/.bitcoin/bitcoin.conf

Bitcoin server starting

15. $ bitcoin-cli getbalance

After this, the following URL error will occur. error: Authorization failed: Incorrect rpcuser or rpcpassword

error: Authorization failed: Incorrect rpcuser or rpcpassword

Which procedure is wrong and how do I fix it? I am really sorry, please teach.


In your bitcoin.conf, remove the spaces before and after the equals (=) sign. I believe the conf file parser does not handle spaces well.

Also, your command has -conf=/.bitcoin/bitcoin.conf, but your conf file is at ~/.bitcoin/bitcoin.conf so it is pointing to the wrong location.

  • As you say, I deleted the space before and after = and corrected the path specification when starting bitcoind, and RPC worked correctly. Thank you!  bitcoind -daemon -datadir=/DATA_DIR/bitcoin -conf=/home/USER_DIR/.bitcoin/bitcoin.conf
