以太坊环境搭建工程(以太坊安装)

文章前言

以太坊作为一个开源的区块链平台,已经在区块链领域中占有重要地位,对于想要了解和使用以太坊的人来说搭建一个以太坊开发环境是必不可少的步骤,本文将介绍如何搭建以太坊开发环境帮助读者更好地理解以太坊的工作原理和开发流程

搭建流程

更新系统

Step 1:更新Ubuntu系统

sudo apt-get update sudo apt-get upgrade

GO语言环境

Step 1:下载Go语言安装包

https://golang.org/dl/

Step 3:然后将Go语言的bin目录添加到系统环境变量中

export PATH=$PATH:/usr/local/go/bin

此时上面的环境变量只是临时有效,我们可以将上述命令添加到.bashrc文件中使其永久生效

export GOROOT=/usr/local/go  export PATH=$PATH:$GOROOT/bin

这条命令的功能包括:

  • 以快速同步的方式启动Geth,通过与以太坊主链进行数据交换,既避免了大量下载历史数据也避免了由此带来的CPU过载

  • 启动了Geth内嵌的交互平台JavaScript控制台,由此可以调用所有官方的Web3函数和Geth自身的应用程序接口

以太坊测试链完全节点方式

这种方式主要是面向开发人员的,在创建真实的合约之前,人们会倾向于在开发、编程、测试过程中不产生真实的资金消耗,因为这样会大幅增加开发成本,但如果在编程和开发期间就采用上述第一种方式直接在以太坊主网络上进行工作,那么由于以太坊的Gas机制将会产生大量的Gas消耗,所以开发人员普遍倾向于在测试网络上开展工作,而在测试网络上合约只使用虚拟的以太币并不产生实际的资金消耗,只有在通过测试网络的验证、完全开发好后,合约才能被部署到以太坊主网络上,这就是基于以太坊测试网络的完全节点方式存在的意义,具体的命令如下

geth --networkid 3 console

备注:以太坊的networkid参数是一个整数,用于标识特定的以太坊网络,这个参数通常在启动以太坊客户端时指定以确保客户端连接到正确的网络,以下是几个常见的networkid参数值

  • 1:主网(Mainnet) 

  • 2:Morden测试网(Morden Testnet) 

  • 3:Ropsten测试网(Ropsten Testnet) 

  • 4:Rinkeby测试网(Rinkeby Testnet) 

  • 42:Kovan测试网(Kovan Testnet)

Rinkeby测试网络全节点方式

以太坊社区的一些成员开发了Rinkeby测试网络,这是基于\\”授权证明(Proof-of-Authority)\\”的,这个网络更轻巧、更安全,但是只支持Geth,具体的进入命令如下:

geth --rinkeby console

文末小结

搭建以太坊开发环境需要一些基础知识和技能,但是一旦完成就可以开始构建智能合约和开发去中心化应用程序了,通过本文提供的步骤和资源,希望读者能够成功地搭建自己的以太坊开发环境并在以太坊生态系统中发挥创造力和创新精神
