第一篇|第一篇 - 从零到壹学习EOS - 搭建EOS开发环境第一篇-从零到壹学习EOS-搭建

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，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。

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 【第一篇|第一篇 - 从零到壹学习EOS - 搭建EOS开发环境】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:

liyuechun:programs yuechunli$ pwd /Users/liyuechun/Desktop/0402/eos/build/programs liyuechun:programs yuechunli$ ls CMakeFilescmake_install.cmake keosd CTestTestfile.cmake eosio-abigennodeos Makefileeosio-applesedemo cleoseosio-launcher liyuechun:programs yuechunli$

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 = true
producer-name = eosio
plugin = eosio::producer_plugin
plugin = eosio::wallet_api_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin

接下来再次启动./nodeos程序，每0.5秒会产生一个区块。
