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
