Windows通过geth同步以太坊区块数据
前言：为了便于测试，我决定在自己电脑同步eth区块数据，虽然中途遇到一些问题，但最终还是同步好了。记录一下，希望能帮到有需要的人~
一 下载geth客户端
既然是通过geth同步，那么肯定是需要下载geth客户端的，同时，geth依赖于go语言环境，所以需要先安装go语言。
安装go语言，具体操作我就不说了，和安装jdk差不多，下载->安装->配置环境变量；下载geth，点击这里下载geth，但是这个链接需要翻墙，不然好慢好慢，甚至打不开。怎么办？没事儿，我为大家准备好了，点我下载geth，提取码：qe2y
二 安装geth开始数据同步
第一步完成之后，安装到想要安装的目录，会生成一个geth.exe程序。请不要直接执行该程序，因为这样的话，默认会把区块数据存放到C盘（系统盘），240G左右，显然不是我们希望看到的。
此外，就算你直接运行geth.exe程序，几乎不会同步数据，因为找不到节点进行数据同步，会一直Looking for peers，但是这个问题在Linux服务器以及mac电脑不会发生，就windows系统会这样，本人亲测，也不知道为什么，这是歧视windos系统吗…
好了，废话不多说了，那么我们应该怎么做呢？
-
通过
cmd进入到geth.exe程序所在目录，win10的快捷键是：按住shift，然后单击鼠标右键，然后点击在此处打开 Powershell窗口 (S)。如下图所示：
关于启动命令，待会儿会做介绍。 -
通过以上命令启动的话，可以指定很多信息，但是还是没有解决我们的找不到节点进行数据同步问题。对于这个问题，我们需要
手动添加可用的以太坊节点让我们的geth程序进行连接。
具体做法是新建一个static-nodes.json文件，并设置为ANSI格式，文件内容具就是可用的eth节点，这些节点从哪儿找呢？点我即可（我是官方节点），我已经帮大家找好了：
多说一句题外话，什么星火节点那些，都是不可用的，坑死人。我这个可用，我是从人家以太坊官网找来的。

把以上内容复制到 static-nodes.json 文件，
说了这么多，static-nodes.json 文件该放在哪里呢？—> 放在eth区块数据目录下，就是上面的启动命令里面的--datadir 所设置的目录，我这里是 E:\blockchain\eth\ethdata 目录。
该目录在geth程序启动之后，会生成geth和keystore目录。
三 geth程序启动命令详解
//windows下geth启动命令
./geth.exe --identity "ethnodebyczj" --datadir "E:/blockchain/eth/ethdata" --syncmode "fast" --rpc --rpcapi "admin,web3,eth,personal,miner,net" --rpcaddr 127.0.0.1 --rpcport 8545 --cache=3072 --maxpeers 1000 --maxpendpeers 900
//参数解析
--identity "ethnodebyczj" 给节点起名
--datadir "E:/blockchain/eth/ethdata" 将区块数据和keystore文件保存在 E:/blockchain/eth/ethdata 目录下
--syncmode "fast" 开启快速同步模式
--rpc 开启RPC服务
--rpcapi "admin,web3,eth,personal,miner,net" 注明要开启哪些RPC服务
--rpcaddr 0.0.0.0 指定RPC服务的IP
--rpcport 8545 指定RPC服务的端口
--cache=3072 分配给Geth的内存，理论上越大同步速度越快
--maxpeers 1000 可连接的节点数量
--maxpendpeers 900 同上
再次强调：static-nodes.json 文件需要放在区块数据存储目录下，并且设置为ANSI格式。
好了，以上就是windows下同步以太坊区块数据的过程，如果再有遇到什么问题，欢迎交流。
