目前來講，任何學習EOS相關技術的資料都來自https://github.com/EOSIO/eos，可能大家在搭建EOS開發環境的過程中，會很迷茫，網上資料都很亂，自己也理不清頭緒，不知如何下手。在這里，春哥將一步步為你揭開層層面紗。

1. 硬件軟件環境

因為EOS的版本太多，所以你需要先知道如何查看EOS對應版本的相關資料。

打開EOS Github官網https://github.com/EOSIO/eos,如下圖所示，點擊master,然后點擊tag，你將會看到不同的版本及其對應的文檔。

我在我電腦安裝過各種各樣的版本，踩過各種各樣的莫名其妙的坑，這篇文章我將以如下配置為大家分享。

• 操作系統

• EOS?版本

2. 編譯設置開發環境

2.1 獲取EOS源碼及其所有子模塊

$ git clone https://github.com/eosio/eos --recursive

如果克隆代碼時未帶--recursive參數，那么可切換到項目路徑下面執行如下命令，更新子模塊。

$ git submodule update --init --recursive

2.2 編譯源碼生成可執行文件

切換到上面的項目根目錄下面，執行如下命令。

liyuechun:eos yuechunli$ ./eosio_build.sh darwin full liyuechun:eos yuechunli$ ls CMakeLists.txt debian ring.dot CMakeModules docs ring.png Docker eos-logo.png scripts Doxyfile eos.doxygen.in star.dot HEADER eosio_build.sh star.png Jenkinsfile externals testnet-diagrams.sh LICENSE.txt libraries testnet.md README.md mesh.dot testnet.template build mesh.png tests circle.yml plugins tools contracts programs liyuechun:eos yuechunli$ ./eosio_build.sh darwin fullBeginning build version: 1.22018年 4月12日 星期四 07時44分06秒 UTCgit head id: 96ee0325cc925ff3e90f865ebc72b01341196e08Current branch: * masterARCHITECTURE: DarwinOS name: DarwinOS Version: 10.13.3CPU speed: 250.00GhzCPU cores: 4Physical Memory: 16 GbytesDisk space total: 465GDisk space available: 133G.....漫長等待，半小時左右，網絡不好的話，40 - 50分鐘。[100%] Linking CXX executable chain_test ld: warning: PIE disabled.

EOS附帶的可執行程序:

liyuechun:programs yuechunli$ pwd /Users/liyuechun/Desktop/0402/eos/build/programs liyuechun:programs yuechunli$ ls CMakeFiles cmake_install.cmake keosd CTestTestfile.cmake eosio-abigen nodeos Makefile eosio-applesedemo cleos eosio-launcher liyuechun:programs yuechunli$

• nodeos：?區塊鏈服務器節點生成組建
• cleos：?和區塊鏈交互的接口命令
• keosd：?EOS?錢包
• eosio-launcher：節點網絡組成和部署的應用

所有這些程序/eos/build/programs都存在于這個文件夾。

2.3 建立區塊鏈節點

切換到目錄eos/build/programs/nodeos下面，然后執行如下命令。

./nodeos命令可附帶?--data-dir 節點文件夾名字?參數，默認文件夾為nodeos。

liyuechun:nodeos yuechunli$ ./nodeos

如下圖所示，執行完./nodeos程序后會抱錯，并且有如下兩個提示。

generating default genesis file /Users/liyuechun/Library/Application Support/eosio/nodeos/config/genesis.json表示創建了一個nodeos節點文件夾。

No producers configured! Please add producer IDs and private keys to configuration.表示

liyuechun:nodeos yuechunli$ cd /Users/liyuechun/Library/Application\ Support/eosio/ liyuechun:eosio yuechunli$ ls nodeos liyuechun:eosio yuechunli$ cd nodeos/ liyuechun:nodeos yuechunli$ ls config data liyuechun:nodeos yuechunli$ cd config/ liyuechun:config yuechunli$ ls config.ini genesis.json liyuechun:config yuechunli$ cd .. liyuechun:nodeos yuechunli$ ls config data liyuechun:nodeos yuechunli$ cd data/ liyuechun:data yuechunli$ ls blocks default.wallet shared_mem liyuechun:data yuechunli$

config是區塊鏈配置文件，data是區塊鏈交易數據、錢包數據存儲文件。我們需要修改config.ini文件里面的相關配置。

我的文件的內容如下：

你需要做如下設置：

• 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

接下來再次啟動./nodeos程序，每0.5秒會產生一個區塊。

3. 查看區塊信息

重新打開一個終端，切換到如下路徑。
