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）。+ |1 ~, M# r+ x

172.xxx.xxx.142
端口4 S2 D9 {# Z6 T
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。

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。

提取Neo
原来文章中有提取neo和gas的方法，但是我现在还不知道为什么要提取Neo，有什么意义，先跟着文档跑着看看。我用的window server会遇到crash，详情请看https://github.com/neo-project/neo-gui/issues/171: {1 W4 F: l! N! Q
希望Neo社区的大牛能解决一下这个问题。3 J% r8 r! ` g, [
一天后，社区给出的解决方案https://github.com/neo-project/neo-gui/issues/171，需要下载两个包2 x2 S) ~9 N5 K8 r4 w0 f. I
结论
虽然配置成功了，但是还不知道能干吗，需要进一步研究。提取Neo也遇到崩溃的情况，发现这个问题，也算做贡献了。
