The truffle framework masks the time consuming steps needed to deploy solidity smart contracts onto Ethereum network. However, it is essential to know the steps masked by truffle in deploying a smart contract to debug production defects

Steps to deploy your smart contracts manually:

Start a new node

mkdir -p ~/.ethereum/conf mkdir -p ~/.ethereum/data/test

sudo apt-get install software-properties-common sudo add-apt-repository -y ppa:ethereum/ethereum sudo apt-get update sudo apt-get install ethereum geth version

Create accounts for transacting

geth --datadir ~/.ethereum/data/test account new

Acct2: passphrase: buyer 6a11688f8b9d46f1eb39f8b677df786b0fc9001f

Acct4: passphrase: dmv adc4d9696fa8879380cfc9a9e07dc3286d5b1510

ls -l data/test/keystore/

geth --datadir ./data/test account list

Create a genesis file in conf folder
