一、下载安装包、解压
litecoin的官方网站为 https://litecoin.org/ 首页最下面有各个系统的下载地址，我们选择下载linux 64位程序，截止到 2020.4.22 最新软件版本为 0.17.1
1、下载 选择 litecoin-0.17.1-x86_64-linux-gnu.tar.gz 适用于centos7的安装包
wget https://download.litecoin.org/litecoin-0.17.1/linux/litecoin-0.17.1-x86_64-linux-gnu.tar.gz
2、解压
tar -zxvf litecoin-0.17.1-x86_64-linux-gnu.tar.gz
二、配置litecoin
1、创建数据存储路径，/data/litecoin/litecoin_data
mkdir -p /data/litecoin/litecoin_data
2、创建配置文件到路径，/data/litecoin/litecoin.conf
vim /data/litecoin/litecoin.conf
3、向配置文件添加内容
点击i切换到编辑模式，输入以下内容：
# rpc 用户名 rpcuser=litecoinrpc # rpc 密码 rpcpassword=litecoin202001
rpcallowip=0.0.0.0/0 # 端口 rpcport=9046 # 是否是服务器 server=1 # 允许后台运行 daemon=1 txindex=1 # 非测试网络 testnet=0 dbcache=8000 # 区块存储位置 datadir=/data/litecoin/litecoin_data #paytxfee=0.00 # rpc 请求超时时间 #rpctimeout=30 # 不挖矿 #gen=0 # 通知到账
4、先按ESC键，输入：x保存编辑并退出
三、运行litecoin
1、进入安装目录，进入litecoin-0.17.1/bin/
cd litecoin-0.17.1/bin/
2、查看版本号（可以不执行）
./litecoind --version
3、将可执行文件拷贝至环境目录
sudo cp litecoin-cli /usr/bin/
sudo cp litecoind /usr/bin/
4、启动运行
sudo litecoind -conf=/data/litecoin/litecoin.conf
出现 Litecoin server starting 说明莱特币正在同步节点.
四、查看同步信息
1、执行命令查看
sudo litecoin-cli -conf=/data/litecoin/litecoin.conf getblockchaininfo
2、结果中 blocks 为目前同步区块数
3、停止服务
sudo litecoin-cli -conf=/data/litecoin/litecoin.conf stop

五、解析交易数据并入库
注意：如果是外网主机，需要设置防火墙端口，此端口跟前面config文件设置的端口一致，
import json import logging import time import pymysql
