Deploy to rinkeby test network

1. Run geth node

geth --rinkeby --http --http.api personal,eth,net,web3 --allow-insecure-unlock

This can take dozens of hours, depending on your machine configuration and internet speed.
This will cost you close to 100GB or so of hard drive space.

2. Create a new account

geth --rinkeby account new

3. Attach into geth console

geth --rinkeby attach

And you can do many things in geth console

eth.syncing     #check the syncing status
eth.accounts    #check all accounts
eth.getBalance(eth.accounts[0]) #check account balance
personal.unlockAccount(eth.accounts[0],null,1200)   #unlock a certain accont for 20 minutes

4. Acquire eth from https://www.rinkeby.io/#faucet

Here they require that you have to post a twitter or facebook, which is disgusting.

5. Migrate

truffle migrate --reset --compile-all --network rinkeby

6. Verify deployment

geth --rinkeby attach

var contractAddress = "Your_Contract_Address"
var contractAbi = [Your_ABI_Array] #copy the abi array in build/contracts/Election.json, turn it into one line style
var electionContract = web3.eth.contract(contractAbi)
var electionInstance = electionContract.at(contractAddress)
electionInstance.candidates(1)
electionInstance.vote(1, {from: eth.accounts[0]});
