Deploying to Ropsten Test Network

A lot of this is from this post.

You need to run a full node (or have access to one) to deploy contracts. Using geth

$ geth --testnet account new

This will prompt for a password to encrypt the wallet. geth stores data in ~/Library/Ethereum on Mac and ~/.ethereum on Linux, as outlined here. Backup your files. For example, your encrypted wallet for the testnet would be located in a file similar to: ~/Library/Ethereum/testnet/keystore/UTC--2017-12-19T08-45-01.800939312Z--0ea7c192efb4d38d500faf471cc57928ee4df649.

You also need to get some Ropsten ETH in the address. Here's a faucet site to seed an account with ETH.

Once you've created a new testnet account, you can run a full node.

$ geth --testnet --fast --rpc --rpcapi eth,net,web3,personal

This runs the RPC API on localhost:8545 by defualt. In order to do any transaction that requires ETH, you must unlock the account you wish to transact with:

$ geth attach http://127.0.0.1:8545
> personal.unlockAccount(web3.eth.accounts[0])
    Unlock account 0x0ea7c192efb4d38d500faf471cc57928ee4df649
    Passphrase: 
    true

The account remains unlocked for a short period of time. Once it's unlocked, you can do things like migrate your truffle contracts

$ truffle migrate --network ropsten
