前言

量化交易的第一步就是获取数据,那么获得比特币的数据,最直接的方法就是搭建一个比特币的客户端,直接从比特币的公链上面同步账本获得数据。比特币网络的构建基础,是基于无中心节点和透明化,这样每个节点都会获得比特币网络中的全量数据。

那么,先我们从搭建bitcoin客户端节点开始吧。

目录

  1. bitcoin安装过程
  2. 启动bitcoin的节点

1. bitcoin安装过程

从源代码安装bitcoin客户端的操作过程,分为以下7步:

  1. 从github下载代码库
  2. 切换最新的版本
  3. 安装系统依赖库
  4. 运行autogen.sh脚本
  5. 运行configure脚本
  6. 运行make和make install
  7. 验证bitcoin安装成功

接下来,我们就一步一步的进行操作。本文使用的Linux系统环境为:Linux Ubuntu 16.04 LTS 64bit。

1.1 先从bitcoin的官方github下载代码库。

安装git的过程,就不再多说了,只需要一条命令apt install git就行了。


> git clone https://github.com/bitcoin/bitcoin.git
> cd bitcoin

1.2 找到最新的tag版本为v0.16.0。


> git tag
noversion
v0.1.5
...
v0.16.0
v0.16.0rc1
v0.16.0rc2
v0.16.0rc3
v0.16.0rc4
v0.2.0
...
v0.9.3
v0.9.3rc1
v0.9.3rc2
v0.9.4
v0.9.5
v0.9.5rc1
v0.9.5rc2

切换到最新版本的分支。


> git checkout v0.16.0

1.3 安装需要依赖的系统工具,这里会用到Libtool、pkg-config、libboost、libdb工具包,需要提前安装。


> apt install libtool
> apt install pkg-config
> apt install libboost-all-dev
> apt install libdb5.3++-dev 
> apt install libevent-dev

1.4 用./autogen.sh脚本进行编译,


> ./autogen.sh 

1.5 运行configure脚本

执行完成后,发现当前目标生了configure文件,然后运行configure文件。运行时,会出现一个BerkerlyDB的错误,它指定要求装4.8版本的BerkerlyDB。解决方法有2种,第1种,去下载对应版本的BerkerlyDB;第二种,跳过这一步的检查。我们先用第2种方法,跳过BerkeleyDB的兼容性检查。


> ./configure
configure: error: Found Berkeley DB other than 4.8, required for portable wallets (--with-incompatible-bdb to ignore or --disable-wallet to disable wallet functionality)

# 跳过BerkeleyDB的兼容性检查
> ./configure --with-incompatible-bdb

1.6 执行make和make install。


> make 
> make install

1.7 验证bitcoin安装成功

验证bitcoin安装成功,有2个命令 bitcoin-cli和bitcoind。我们需要检查一下,是否这个启动命令,安装到在系统环境中。

  • bitcoind,用于启动bitcoin的节点,同步账本数据。
  • bitcoin-cli,用于与bitcoind节点通信。

查看启动命令的系统安装位置。


> which bitcoin-cli
/usr/local/bin/bitcoin-cli

> which bitcoind
/usr/local/bin/bitcoind

分别查看bitcoind 和 bitcoin-cli 命令的帮助信息。


> bitcoind -help
> bitcoin-cli -help

这样就完成了,bitcoin的客户端的安装。

2. 启动bitcoin节点

通过bitcoind命令启动bitcoin的核心客户端程序。运行前,我先要定义一个bitcoin.conf的配置文件,用于设置RPC-JSON的访问用户。

新建配置文件 .bitcoin/bitcoin.conf。设置rpc用户的账号和密码,请大家按照复杂密码设定要求设置。官方推荐的bitcoin.conf文件的配置项,打开文件


> vi .bitcoin/bitcoin.conf

rpcuser=bsspirit
rpcpassword=98jfidayelqlvjieJDIjda

启动bitcoind服务端,并把数据写入到/data/btc目录,在控制台打印输出。


> bitcoind -datadir=/data/btc -conf=/root/.bitcoin/bitcoin.conf -printtoconsole

启动参数:

  • -datadir,用于指定目录
  • -conf,用于指定配置文件
  • -printtoconsole,用于控制台输出

如果打算后台执行,可以增加-daemon参数。同时,去掉-printtoconsole参数,在后面的日志文件中,进行输出。

看到这些信息,代表你的bitcoin程序已经启动了。有几十G的数据,需要同步!

安装bitcoin相比用apt安装要复杂一些,不过按照官方文档的介绍基本能走通的,安装过程对于技术人来不是什么大问题。不同的公链,有不同的节点软件,安装方法也不同,下一篇文章将介绍以太坊的客户端Geth的安装
