本文详细介绍如何在CentOS 7环境下安装配置Geth客户端，包括创建账户、初始化创世块、启动Geth节点等步骤，并提供了命令行操作示例。

0、安装环境

虚拟机中安装的操作系统：Centos7

参考官网文档：Private Networks | Go Ethereum

1、创建账户

（1）创建目录rungeth并进入

[root@localhost local]# cd geth-alltools-1.10.16/     #进入geth目录
[root@localhost geth-alltools-1.10.16]# mkdir rungeth #创建目录rungeth
[root@localhost geth-alltools-1.10.16]# cd rungeth    #进入rungeth目录

（2）创建账户

[root@localhost rungeth]# geth account new --datadir data
INFO [03-25|00:43:10.089] Maximum peer count                       ETH=50 LES=0 total=50
INFO [03-25|00:43:10.089] Smartcard socket not found, disabling    err="stat /run/pcscd/pcscd.comm: no such file or directory"

Your new key was generated

Public address of the key:   0x654FFcC87B54280d5BAA24CA7D366AD21E3A3C73  #生成账户地址
Path of the secret key file: data/keystore/UTC--2022-03-24T16-43-17.897096805Z--654ffcc87b54280d5baa24ca7d366ad21e3a3c73

- You can share your public address with anyone. Others need it to interact with you.
- You must NEVER share the secret key with anyone! The key controls access to your funds!
- You must BACKUP your key file! Without the key, it's impossible to access account funds!
- You must REMEMBER your password! Without the password, it's impossible to decrypt the key!

（3）查看生成目录及文件

[root@localhost rungeth]# tree data
data
└── keystore
    └── UTC--2022-03-24T16-43-17.897096805Z--654ffcc87b54280d5baa24ca7d366ad21e3a3c73

1 directory, 1 file

（4）查看账户信息

[root@localhost rungeth]# cat data/keystore/UTC--2022-03-24T16-43-17.897096805Z--654ffcc87b54280d5baa24ca7d366ad21e3a3c73  | jq .
{
