前言

geth 是将计算机变成一个以太坊节点，连接到以太坊网络的客户端。

对于geth的几个问题：

有了 geth 之后能做什么？
该怎么用？
用了之后能了解到什么？

能做几件事：

成为一个以太坊节点，可以是：全节点、矿工节点、归档节点
可以当在一个gRPC 的查询工具来用
生成账户等操作

一句话总结：geth就代表运行在你电脑上的以太坊程序。

环境准备

这里说明只基于对开发环境的基础配置，官方要求的配置更高

最小硬件要求

CPU 2+ cores
4GB RAM
1TB
8 MBit/sec

go安装

go1.16.x 安装
gcc 编译geth

注意需要修改一下go代理：

go env -w GOPROXY=https://goproxy.cn

安装gcc

yum install gcc

编译

下载源码之后，看一下README.md，使用make geth就行编译，编译一下

git clone https://github.com/ethereum/go-ethereum.git
cd  go-ethereum
# 查看所有分支 git brarnch -a
git checkout release/1.9
make geth
make all

开始编译后输出：

Done building.
Run "./build/bin/geth" to launch geth.

可以看到geth被编译到了: ./build/bin/geth，这个路径。

执行下看看编译是否成功:

./build/bin/geth --help

成功
