rpcbind=0.0.0.0

-- set up leveldb
sudo apt-get install libsnappy-dev
export VER="1.20"
wget https://github.com/google/leveldb/archive/v${VER}.tar.gz
tar xvf v${VER}.tar.gz
rm -f v${VER}.tar.gz
cd leveldb-${VER}
make (may require doing: sudo apt-get install build-essential libssl-dev libffi-dev python-dev)
sudo scp -r out-static/lib* out-shared/lib* "/usr/local/lib"
cd include
sudo scp -r leveldb /usr/local/include
sudo ldconfig

-- making default python3 to upgrade to python3.7
sudo apt update -y
sudo apt install python3.7
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 2
sudo update-alternatives --config python3 (select the wanted number and hit return)
sudo rm /usr/bin/python3
sudo ln -s python3.7 /usr/bin/python3

-- install more supportive packages
python3.7 -m pip install --upgrade pip setuptools wheel
python3.7 -m pip install --upgrade aiohttp pylru leveldb plyvel aiorpcx ecdsa
