#Gathering Information

NODEIP:IP ADDRESS of your Bitcoin NODE 
NODEUSER:Username of your Bitcoin NODE  usually root
NODEPWD:Password of your Bitcoin NODE for ssh

#Choosing Information for RPC

RPCUser: Choose RPC Username [Alpha Numeric] atleast 16 chars
RPCPass: Choose RPC Password[Alpha Numeric] Keep strong 32 chars
RPCPort:Choose uncommon port from 1000 to 65000 example 5351
ACCESS_IP: IP address which will access your Bitcoin node [Exchange IP]

Now login to your NODEIP with ssh root@NODEIP

cd /opt/
wget https://bitcoin.org/bin/bitcoin-core-22.0/bitcoin-22.0-x86_64-linux-gnu.tar.gz
tar -xvf bitcoin-22.0-x86_64-linux-gnu.tar.gz
sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-22.0/bin/*

Run bitcoind and stop with ctrl+c

bitcoin-cli createwallet "default"

cd /root/.bitcoin/

sudo nano bitcoin.conf

and Paste below init [Make sure to replace variables

rpcuser=[RPCUser]
rpcpassword=[RPCPass]
rpcport=RPCPort
rpctimeout=5
rpcallowip=[ACCESS_IP]
rpcbind=0.0.0.0
testnet=0
server=1
prune=550
addresstype=p2sh-segwit
wallet=default
#daemon=1

This now becomes your command bitcoind -server -rpcbind=0.0.0.0 -rpcport=RPCPort -rpcallowip=ACCESS_IP -rpcuser=RPCUser -rpcpassword=RPCPass -prune=550 -addresstype=p2sh-segwit

or You can supervisor to run it

sudo apt-get install supervisor

After above use following

cd /etc/supervisor/conf.d/
sudo nano bitcoin.conf

Next enter following information

[program:bitcoin]
command=/usr/local/bin/bitcoind -datadir=/root/.bitcoin -conf=/root/.bitcoin/bitcoin.conf
autostart=true
autorestart=true
stderr_logfile=/var/log/supervisor/bitcoin.err.log
stdout_logfile=/var/log/supervisor/bitcoin.out.log

Now Save it and run following command

supervisorctl reload

To check Log use command

supervisorctl
tail -f bitcoin

#Testing Connection

curl --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getblockchaininfo","params":[]}' -H 'content-type:text/plain;' http://RPCUser:RPCPass@127.0.0.1:RPCPort/

If above response comes empty then you can use verbose to debug

curl --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getblockchaininfo","params":[]}' -H 'content-type:text/plain;' http://RPCUser:RPCPass@127.0.0.1:RPCPort/ -v

#creating a wallet

 bitcoin-cli createwallet wallet

#Check if wallet is connected

bitcoin-cli getwalletinfo
