手把手教你厘清EOS开发环境搭建来龙去脉

目前来讲,任何学习EOS相关技术的资料都来自https://github.com/EOSIO/eos,可能大家在搭建EOS开发环境的过程中,会很迷茫,网上资料都很乱,自己也理不清头绪,不知如何下手。在这里,春哥将一步步为你揭开层层面纱。

 

1. 硬件软件环境

因为EOS的版本太多,所以你需要先知道如何查看EOS对应版本的相关资料。

打开EOS Github官网https://github.com/EOSIO/eos,如下图所示,点击master,然后点击tag,你将会看到不同的版本及其对应的文档。

我在我电脑安装过各种各样的版本,踩过各种各样的莫名其妙的坑,这篇文章我将以如下配置为大家分享。

2. 编译设置开发环境

2.1 获取EOS源码及其所有子模块
$ git clone https://github.com/eosio/eos --recursive

如果克隆代码时未带--recursive参数,那么可切换到项目路径下面执行如下命令,更新子模块。

$ git submodule update --init --recursive

2.2 编译源码生成可执行文件

切换到上面的项目根目录下面,执行如下命令。

EOS附带的可执行程序:

nodeos: 区块链服务器节点生成组建cleos: 和区块链交互的接口命令keosd: EOS 钱包eosio-launcher:节点网络组成和部署的应用

所有这些程序/eos/build/programs都存在于这个文件夹。

2.3 建立区块链节点

切换到目录eos/build/programs/nodeos下面,然后执行如下命令。

./nodeos命令可附带 --data-dir 节点文件夹名字 参数,默认文件夹为nodeos

liyuechun:nodeos yuechunli$ ./nodeos 

如下图所示,执行完./nodeos程序后会抱错,并且有如下两个提示。

config是区块链配置文件,data是区块链交易数据、钱包数据存储文件。我们需要修改config.ini文件里面的相关配置。

我的文件的内容如下:

你需要做如下设置:

genesis-json = "/Users/liyuechun/Library/Application Support/eosio/nodeos/config/genesis.json"enable-stale-production = trueproducer-name = eosioplugin = eosio::producer_pluginplugin = eosio::wallet_api_pluginplugin = eosio::chain_api_pluginplugin = eosio::http_plugin

接下来再次启动./nodeos程序,每0.5秒会产生一个区块。
