智能合约发布准备

我们将这份智能合约部署到Geth节点运行的私有区块链上，如果还未开始，请按如下命令启动Geth节点并启用挖矿。

cd ether-test
geth --datadir ./db/ --rpc --rpcaddr=127.0.0.1 --rpcport 8545 --rpccorsdomain "*" \
   --rpcapi "eth,net,web3,personal,admin,shh,txpool,debug,miner" \
   --nodiscover --maxpeers 30 --networkid 198989 --port 30303 \
   --mine --minerthreads 1 \
   --etherbase "0x53dc408a8fa060fd3b72b30ca312f4b3f3232f4f"

好，Geth 节点开始稳步挖矿，区块链已经运行。我们再用attach命令依附到正在运转的Geth节点上，获得操作台的控制权。

我们导入刚才建立好的 temp.js 文件。

}

至此我们已经将编译好的智能合约顺利导入了开发环境中。
