安装 TestRPC -- npm install -g ethereumjs-testrpc 部署合约之前启动testrpc -- testrpc --gasLimit 0x800000000
truffle ubox metacoin //创建项目
truffle develop //进入控制台
编译项目 $ truffle compile --all//编译项目
truffle migrate --reset --network rinkeby
$ truffle deploy 启动服务 $ truffle serve
默认的函数参数，包括返回的参数，他们是memory。默认的局部变量是storage的。而默认的状态变量（合约声明的公有变量）是storage。
另外还有第三个存储位置calldata。它存储的是函数参数，是只读的，不会永久存储的一个数据位置。外部函数的参数（不包括返回参数）被强制指定为calldata。效果与memory差不多。
