ubuntu 装以太坊,Ubuntu系统下以太坊搭建与运行全攻略

小编

亲爱的技术爱好者们,你是否曾梦想过自己动手搭建一个区块链网络,体验一把成为“矿工”的快感?今天,就让我带你一起走进Ubuntu的世界,亲手装一个以太坊私有链,感受区块链的魅力吧!

一、准备工作:搭建以太坊环境

首先,你需要一台运行Ubuntu操作系统的电脑。如果你还没有安装Ubuntu,可以去官网下载并安装。安装完成后,我们就可以开始搭建以太坊环境了。

1. 更新系统源

打开终端,输入以下命令更新系统源:

```bash

sudo apt-get update

```

2. 安装依赖

为了确保以太坊顺利安装,我们需要安装一些依赖库。输入以下命令:

```bash

sudo apt-get install software-properties-common

sudo add-apt-repository -y ppa:ethereum/ethereum

sudo add-apt-repository -y ppa:ethereum/ethereum-dev

sudo apt-get update

sudo apt-get install ethereum

```

3. 验证安装

输入以下命令,查看geth版本信息,确认安装成功:

```bash

geth -h

```

如果看到类似以下信息,说明安装成功:

```

Usage:

geth [options] command [command options]
