NEO 私有链的部署至少需要 4 台服务器才能取得共识，每台服务器对应一个共识节点。在阿里云上可以买按量付费的虚拟机（机器都是window server）。
记录下四台机器的内网IP地址，后面要用。
172.xxx.xxx.142
如果你想让外部程序访问该节点的 API 需要开放防火墙端口：10331-10334, 20331-20334
阿里云的vpc如果在一个安全组内就不需要设置。也可以通过安全组开放所有入口。

运行环境
运行 NEO 节点需要安装 .NET Core Runtime，需要安装 1.0.1 或以上版本
Windows 系统下的安装方法
在 Windows 系统下安装 .NET Core 非常方便，直接下载运行即可。
NOTE
Windows可能还需要安装Microsoft Visual C++ 2015 redistributable Update 3（https://www.microsoft.com/en-us/download/details.aspx?id=53840) ，否则后面无法启动Neo-CLI。
在四台机器上分别创建钱包数据库，数据库文件会默认生成在neo-cli的目录下面
create wallet wallet.json
db3后缀名的数据库文件不支持了
neo1
neo> create wallet wallet.db3 Wallet files in db3 format are not supported, please use a .json file extension. neo> create wallet wallet.json password: ******** password: ******** address: AS43TUy7VtuGpNJh3YC2NM3asTv3s6piyk pubkey: 02d57c9bbc42b45943867dff0180cb9df266b46db7d027a283eabc7c4b8819c86c
记录下另外几台机器的钱包公钥

}open wallet wallet.json start consensus
如果前面打开过cli，请删除chain目录下的文件，这样区块链高度会从1开始。
截取其中一个打印，后面方便调试的时候研究
