我们可以通过搭建以太坊的私有节点,模拟以太坊挖矿、交易、部署运行智能合约,从而达到测试开发的目的。下面具体说明搭建过程:
1. 创建新帐号
geth --datadir {eth_dir} account new //其中 eth_dir 是私有节点的数据目录
2. 创建 genesis.json 文件,保存创世纪块的配置信息
{ "config": { "chainId": 1, "homesteadBlock": 0, "eip155Block": 0, "eip158Block": 0 }, "alloc" : { "f985f8578206c6d317785cf131682259bf84588f": {"balance": "100000001"} }, "coinbase" : "0x0000000000000000000000000000000000000000", "difficulty" : "0x20000", "extraData" : "", "gasLimit" : "0x4c4b40", "nonce" : "0x0001000000000042", "mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000", "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000", "timestamp" : "0x00" }
3.初始化创世纪块
geth --datadir {eth_dir} init {./genesis.json}
4. 启动以太坊工作节点
geth --verbosity 6 --datadir e:/eth_dir --networkid 13579 --etherbase f985f8578206c6d317785cf131682259bf84588f --port 30303 --rpcport 8545 --rpcaddr localhost --rpc --rpccorsdomain http://localhost:3000 --ws --wsorigins "http://localhost:3000" --wsport 8546 --unlock f985f8578206c6d317785cf131682259bf84588f --nodiscover --mine --minerthreads 1 --password e:/eth_dir/passwd console 2>>eth_output.log
