I figured it out. in truffle.js you can specify from: field like this:

// Allows us to use ES6 in our migrations and tests.
require('babel-register')

module.exports = {
  networks: {
    development: {
      host: 'localhost',
      port: 8545,
      network_id: '*', // Match any network id
      from: '0xA21983B35C767CF8609D95F4886C9A18A194D8AA'
    }
  }
}

that's the public address, but how does truffle knows the associated private key? – David 天宇 Wong Sep 29 '17 at 07:04
@David天宇Wong it doesn't need to know, your geth/parity node doesn't even know it. You have to unlock your key – rstormsf Oct 01 '17 at 02:02

It needs to know it to sign transactions coming from this address. If you deploy a contract you need to sign the transaction deploying that contract. – David 天宇 Wong Oct 02 '17 at 20:55
