Deploy a smart contract using geth - Blockchain as a Service

Start an interactive JavaScript console to connect to a Quorum node, you can refer to the document Setup geth interactive JavaScript console to establish an interactive JavaScript console.

Create an Ethereum account by entering the following instructions in the interactive JavaScript console. If you have already created an Ethereum account on your node, you can also use your existing account to complete the following steps.

// create a account that use empty password
var account = personal.newAccount("");
// using an existing account in node
// var account = eth.accounts[0]
// unlock account for 300 seconds with empty password
personal.unlockAccount(account, "", 300);
// set it as default account
web3.eth.defaultAccount = account;

Use a thirdparty compilation tool such as solc or truffle to compile smart contracts and get the ABI and bytecode of the smart contracts. You can compile your contracts by referring to Compile smart contract.

Enter the following example commands in the interactive JavaScript console to deploy contracts in the Quorum network. When you need to deploy your own smart contracts, you need to replace abi and bytecode with your contract compilation results.

// abi for contract
var abi = [{"constant":true,"inputs":[],"name":"storedData","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"x","type":"uint256"}],"name":"set","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"get","outputs":[{"name":"retVal","type":"uint256"}],"payable":false,"type":"function"},{"inputs":[{"name":"initVal","type":"uint256"}],"payable":false,"type":"constructor"}];
// compiled solidity bytecode code using https://github.com/jpmorganchase/quorum-examples/blob/master/examples/7nodes/simplestorage.sol
var bytecode = "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";
var address = ""
var simpleContract = web3.eth.contract(abi);
var simple = simpleContract.new(42, {
 from: account,
 data: bytecode,
 gas: 0x47b760
}, function(e, contract) {
 if (e) {
     console.log("err creating contract", e);
 } else {
     if (!contract.address) {
         console.log("Contract transaction send: TransactionHash: " + contract.transactionHash + " waiting to be mined...");
     } else {
         console.log("Contract mined! Address: " + contract.address);
         address = contract.address
         console.log(contract);
     }
 }
});

When a transaction of deploying a contract is packaged by a consensus node, you can see the contract address after deployment in the interactive JavaScript console, and then you can send a transaction to that address to invoke the contract.
