centero7下比特币全节点搭建（此部分采用二进制源码的方式安装）：

系统配置要求：

硬盘：300G。

内存：16G。一般来说4G就够，但如果要查历史记录，需要加载完整的交易索引表-tindex，这导致需要8G+的内存

系统选择：centos 7版本

在桌面建立文件：

mkdir bitcoin

mkdir bitcoinData (存放同步数据的文件)

mkdir bitcoinNode(bitcoin节点)

安装：

节点下载地址： https://bitcoincore.org/bin/bitcoin-core-0.17.0.1/bitcoin-0.17.1-x86_64-linux-gnu.tar.gz

tar -xzvf bitcoin-0.17.1-x86_64-linux-gnu.tar.gz -C /bitcoinNode

将bitcoinNode中以下几个文件拷贝到/usr/local/bin

bitcoin-cli bitcoind bitcoin-qt bitcoin-tx

节点配置

初始启动时：bitcoind -reindex=1 -txindex=1 -daemon

bitcoin-cli getblockchaininfo 可查看区块信息
