真实配置过程
1. geth --datadir "/Users/zsk/Library/Ethereum" --dev 解析: --datadir "/Users/zsk/Library/Ethereum" 就是创建数据库和密钥存储库的相应文件和Ethereum文件夹 --dev 开发者模式(预先配置的带有多个调试标志的专用网络) error: Fatal: Error starting protocol stack: database already contains an incompatible genesis block (have d4e56740f876aef8, new e5be92145a301820). 暂未找到解决方案，但是不影响测试 2. geth --dev console 2>>file_to_log_output 解析: --dev 开发者模式 console 启动交互式JavaScript环境 该命令会打开geth控制台，同时在当前命令行所在的文件目录下生成一个叫做file_to_log_output的日志文件，一些操作打印日志会直接记录在这个文件中 3. geth控制台操作 eth.accounts // 查看当前用户，返回值为一个数组 personal.newAccount('密码') // 创建一个新的用户 user1 = eth.accounts[0] // 把数组的第一个值赋予user1 eth.getBalance(user1) // 查询这个账户的余额 miner.start() // 开始挖矿 miner.stop() // 停止挖矿 personal.unlockAccount(user1,'123456') // 解锁用户1 eth.sendTransaction({from: user1, to: user2, value:web3.toWei(3,'ether')}) // user1 向 user2 转3个币 // 现在去查询user2余额还是为0，每次交易的确认，其实都是需要挖矿的，也就是被其他矿工共识确认，然后才能加入区块链的账本中 // 所以在此挖矿 miner.start() // 开始挖矿 miner.stop() // 过一会停止挖矿 // 此时在查询，就会发现user2中有3个币 eth.getBalance(user2)
