前言

量化交易的第一步是获取数据btc客户端下载，所以获取比特币数据最直接的方式就是搭建比特币客户端，直接从比特币公链同步账本获取数据。比特币网络的基础是去中心化的节点和透明性，这样每个节点都会获得比特币网络中的全部数据。

因此，让我们从构建比特币客户端节点开始。

比特币安装过程启动比特币节点 1. 比特币安装过程

从源码安装比特币客户端的操作过程分为以下7个步骤：

从 github 下载代码库并切换到最新版本。安装系统依赖库。运行 autogen.sh 脚本。运行配置脚本。运行 make 和 make install 验证比特币安装是否成功。

接下来，我们将一步步进行。本文使用的Linux系统环境为：Linux Ubuntu 16.04 LTS 64bit。

1.1 首先从比特币官方github下载代码库。

安装git的过程就不多说了，只需要一个命令：apt install git。


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

1.2 找到最新的tag版本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，需要提前安装好。


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

1.4 使用./autogen.sh脚本编译，


> ./autogen.sh

1.5 运行配置脚本

执行完成后，发现已经为当前target生成了configure文件，然后运行configure文件。运行时会出现BerkerlyDB错误，提示需要4.8版本的BerkerlyDB。有两种解决方法。首先是下载对应版本的BerkerlyDB；二是跳过这一步检查。我们先用第二种方法，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 验证比特币安装是否成功

要验证比特币是否成功安装，有 2 个命令 bitcoin-cli 和 bitcoind。我们需要检查系统环境中是否安装了这个启动命令。

查看launch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

这样就完成了比特币客户端的安装。

2.启动比特币节点

通过bitcoind命令启动比特币核心客户端程序。在运行之前，我需要定义一个bitcoin.conf配置文件来设置RPC-JSON访问用户。

创建一个新的配置文件 .bitcoin/bitcoin.conf。设置rpc用户的帐号和密码，请按照复杂的密码设置要求进行设置。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服务器，将数据写入/data/btc目录，并在控制台打印输出。


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

启动参数：

如果打算在后台执行，可以增加-daemon参数。同时去掉-printtoconsole参数，在如下日志文件中输出。

看到这个信息就说明你的比特币程序已经启动了。有几十G的数据需要同步！

安装bitcoin比用apt安装要复杂一些，但是按照官方文档的介绍基本就可以搞定，安装过程对技术人员来说问题不大。不同的公链节点软件不同btc客户端下载，安装方式也不同。下一篇文章将介绍以太坊客户端Geth的安装。
