一键在Ubuntu上运行Bitcoin全节点(BTC系列教程1)

现在经常需要btc全节点。很多人得开着电脑24小时不关机，属实很麻烦。

但是如果购买一个小主机，配上Ubuntu系统，24小时运行全节点。开启RPC之后，电脑随时都能连上使用。当然也可以做Atom索引等本文将会讲解如何搭建一个基于ubuntu系统的bitcoin全节点。

需求

操作系统os: ubuntu20.04
内存： 2G
SSD： 1TB

对于家用小服务器，我推荐买个N100的mini主机大概几百块钱+一块2tssd，总成本可能在1k左右功率在10w左右，可以24小时不关机。一个linux设备代表能拥有什么呢：各种好玩的docker服务，各种脚本

如何安装BTC全节点

使用root用户登陆上ubuntu之后，运行下面命令即可。

wget -O bitcoin_node.sh https://pub-e3b4652c5d5f4c1b8fbfdff04685c330.r2.dev/bitcoin_node.sh && chmod +x bitcoin_node.sh && sudo ./bitcoin_node.sh

当然这个脚本也可以在window开启ubuntu的wsl2子系统使用，也可以在各种云服务使用。只要是X86的Ubuntu20.04都可以。安装脚本开源，安全放心～可以直接访问查看

在运行过程中，会提示让你输入
rpc user：输入你想配置的帐号
rpc password ：输入你想配置的密码是否开启RPC
Do you want to enable external RPC access? (yes/no)
yes: 家里内网都可以访问rpc，（如果机器有外网ip的话，外网也可以访问）
no: 只有本机可以访问rpc （比如做atom索引之类的使用）
等待提示，安装完成Bitcoin Core is now installed and running.
输入这个命令即可以查看到同步高度:bitcoin-cli getblockchaininfo
后续更新如何在这台机器里面一键启动Atom索引,代码也完整的放到下面

#!/bin/bash
