Compiling Bitcoin Core (Debian, v23)

Install dependencies (as root)

su root
apt update && apt install git build-essential libtool autotools-dev automake pkg-config bsdmainutils python3 libssl-dev libevent-dev libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev libminiupnpc-dev libzmq3-dev libprotobuf-dev protobuf-compiler git ccache libsqlite3-dev

Create and become user 'bitcoin'

/sbin/adduser bitcoin
su bitcoin
cd

Clone bitcoin core repo

git clone https://github.com/bitcoin/bitcoin.git
cd bitcoin

Checkout and compile

git checkout v23.0
./contrib/install_db4.sh `pwd`
./autogen.sh
export BDB_PREFIX='/home/bitcoin/bitcoin/db4'
ls $BDB_PREFIX # test env var
./configure BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include"
make -j4 # or appropriate number of CPU cores

Post-compilation testing

make check
test/functional/test_runner.py

Install (as root)

su root # or 'exit' to become root
make install

Obtain bitcoin.conf (or use a pre-exising one)

su bitcoin
mkdir ~/.bitcoin
cp share/examples/bitcoin.conf ~/.bitcoin/

Make adjustments to bitcoin.conf for installation needs (e.g., maxconnections, maxuploadtarget).

Start bitcoind

On mainnet

bitcoind -daemon

On testnet3

bitcoind -testnet -daemon

Check logs for status details

tail -f ~/.bitcoin/debug.log
tail -f ~/.bitcoin/testnet3/debug.log

Stop bitcoind

bitcoin-cli stop # for mainnet
bitcoin-cli -testnet stop # for testnet3
