Install bitcoind
https://bitcoincore.org/binFind the appropriate version on the official website , it must be a version below 0.18.0, otherwise the node will not be connected, the configuration of the new version needs to be studied
root@ubuntu:~# wget https://bitcoincore.org/bin/bitcoin-core-0.17.1/bitcoin-0.17.1-x86_64-linux-gnu.tar.gz
root@ubuntu:~# tar zxf bitcoin-0.17.1-x86_64-linux-gnu.tar.gz
Create soft connection
root@ubuntu:~# cd bitcoin-0.17.1
root@ubuntu:~# ln -fs /root/bitcoin-0.17.1/bin/bitcoind /usr/local/bin/bitcoind
root@ubuntu:~# ln -fs /root/bitcoin-0.17.1/bin/bitcoin-cli /usr/local/bin/bitcoin-cli
Check the version number
root@ubuntu:~# bitcoind --version
Configure bitcoin parameters
root@ubuntu:~$ mkdir .bitcoin #创建目录
root@ubuntu:~$ cd .bitcoin/
root@ubuntu:~$ vi bitcoin.conf
Copy all the following information, and modify rpcuser (RPC user name), rpcpassword (RPC user password), rpcallowip (ip address allowed to access) and save

Access Json-RPC interface
In the main network ( mainnet) and test network ( testnet) modes, the json-rpcport is used to access .bitcoin/bitcoin.confthe 18332port configured in use , but in the private chain ( regtest) mode, it seems that the configuration does not work. It is still necessary to access the default 18443port.
We can use postmanor curlother tools to access: bitcoinrpc: bitcoinrpc is the rpc username and password respectively
curl -s -X POST --user bitcoinrpc:bitcoinrpc -H 'content-type: text/plain;' http://127.0.0.1:18443/ --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnetworkinfo", "params": [] }'
