EOS是什么
EOSIO是一個它開源的區塊鏈項目，旨在實現分散式應用程序的垂直和水平擴展（“EOSIO軟件”），并可用于啟動私有和公共區塊鏈網絡。這是通過類似操作系統的構造實現的，可以在其上構建應用程序。該軟件提供帳戶，身份驗證，數據庫，異步通信以及跨多個CPU核心和/或群集的應用程序調度。由此產生的技術是一種區塊鏈架構，有可能每秒擴展到數百萬個事務，注意，只是有可能擴展到數百萬個事物。消除了用戶費用，并允許快速輕松地部署分散式應用程序。
在安裝錢包節點之前，咱們應該先了解一下EOS的架構，下面是EOS的一個模塊架構。
nodeos（node + eos = nodeos）-可以使用插件配置以運行節點的核心EOSIO節點守護程序。示例用法是塊生產，專用API端點和本地開發。
cleos（cli + eos = cleos）-與區塊鏈交互并管理錢包的命令行界面
keosd（key + eos = keosd）-將EOSIO密鑰安全存儲在錢包中的組件。
eosio-cpp - eosio.cdt的一部分，它將C++代碼編譯為WASM并可以生成ABI
安裝EOS錢包節點
下面咱們使用二進制文件來構建項目，從源碼來構建項目的話，這種操作方式比較復雜，而且很浪費時間，這里不推薦這種方式。
1.各種平臺上安裝EOS
1.1.在mac平臺下安裝EOS
brew tap eosio/eosio brew install eosio
1.2.Ubuntu18.04
wget https://github.com/eosio/eos/releases/download/v1.5.0/eosio_1.5.0-1-ubuntu-18.04_amd64.deb sudo apt install ./eosio_1.5.0-1-ubuntu-18.04_amd64.deb
1.3.centos
wget https://github.com/eosio/eos/releases/download/v1.5.0/eosio-1.5.0-1.el7.x86_64.rpm sudo yum install ./eosio-1.5.0-1.el7.x86_64.rpm
1.5.Fedora
wget https://github.com/eosio/eos/releases/download/v1.5.0/eosio-1.5.0-1.fc27.x86_64.rpm sudo yum install ./eosio-1.5.0-1.fc27.x86_64.rpm
2.啟動節點并對節點進行配置
2.1.啟動Keosd
keosd &
執行上面這個命令之后，你應該可以看到類似下面這樣的輸出，按Enter鍵可以退出來。

2.2.啟動nodeos
nodeos -e -p eosio --plugin eosio::producer_plugin --plugin eosio::chain_api_plugin --plugin eosio::http_plugin --plugin eosio::history_plugin --plugin eosio::history_api_plugin --access-control-allow-origin='*' --contracts-console --http-validate-host=false --verbose-http-errors --filter-on='*' >> nodeos.log 2>&1 &
這些設置可實現以下功能：
在開發目錄下的eosio目錄中使用工作目錄進行區塊鏈數據和配置。這里我們分別使用eosio/data和eosio/config
運行Nodeos。此命令加載所有基本插件，設置服務器地址，啟用CORS并添加一些合同調試和日志記錄。
無限制地啟用CORS（*）
在上面的配置中，CORS僅用于開發目的*，您永遠不應在可公開訪問的節點上啟用CORS for *！
3.檢查節點的和錢包的情況
3.1.檢查節點的情況
運行下面的命令
tail -f nodeos.log
你可以看到終端下面有這些輸入

按CNTL + C鍵退出日志。
3.2.檢查錢包的情況
打開shell并運行cleos命令列出可用的錢包
cleos wallet list
你應該看到下面這樣的輸出
Wallets: []
3.3.檢查Nodeos末端節點
這將檢查RPC API是否正常工作，選擇一個。
檢查瀏覽器中chain_api_plugin提供的get_info端點：
http：// localhost：8888 / v1 / chain / get_info
檢查相同的事情，但在主機的控制臺中
curl http://localhost:8888/v1/chain/get_info
讀到這里，小伙伴們學會怎么安裝了嗎？
