<h3>docker安装</h3>
<ul>
<li>下载docker.dmg文件，然后点击，一步步操作(mac下)</li>
<li>执行docker version，查看是否安装成功</li>
</ul>
<h2>操作流程</h2>
<ol>
<li>新建文件Dockerfile和bitcoin.conf(已上传到gitlab),以构建镜像
Dockerfile:
<pre><code>FROM buildpack-deps:stretch-curl

<ol>
<li>使用命令：docker build -t btc_docker:dev ./,构建镜像</li>
<li>执行docker images查看生成的镜像</li>
<li>启动镜像：
<pre><code>全节点模式：docker run -it -v /Users/admin/Desktop/docker-build/btc_blockdata:/root/.bitcoin -p 8332:8332 btc_docker:dev</code></pre>
<p>参数说明：</p>
<ul>
<li>-p 8332:8332-映射端口</li>
<li>-v /Users/admin/Desktop/docker-build/btc_blockdata 指定挂载出来的区块数据存储目录，可自定义</li>
</ul></li>
<li>容器启动后，可执行docker exec -it 87fadc0249a9 /bin/bash #进入容器</li>
<li>执行bitcoin-cli --conf=/conf/bitcoin.conf getblockchaininfo
<h2>搭建测试私有链</h2>
<h3>参考链接</h3>
<p><code>https://blog.csdn.net/yzpbright/article/details/81004202</code></p>
<h3>操作流程</h3>
<ul>
<li>拉取比特币测试网络(bitcoin-testnet)的Docker镜像 :sudo docker pull freewil/bitcoin-testnet-box</li>
<li>运行Docker镜像 docker run -t -i -p 19001:19001 -p 19011:19011 freewil/bitcoin-testnet-box</li>
<li>进入Docker运行环境后，输入make start命令来启动两个比特币节点，组成比特币测试网络</li>
<li>模拟运行两个比特币测试钱包节点，组成一个私有范围的比特币测试网络。输入make getinfo可以查看测试网络节点状态信息
<h2>代码连接示例（node.js）</h2>
<p>bitcore-node.js:</p>
<pre><code>var bitcore = require('bitcore-node');

}]
}
}
]
});
module.exports = node;</code></pre>
<p>bitcore-node.js:</p>
