区块链操作系统- EOS 环境安装

EOS是什么

EOSIO是一个它开源的区块链项目，旨在实现分散式应用程序的垂直和水平扩展（“EOSIO软件”），并可用于启动私有和公共区块链网络。这是通过类似操作系统的构造实现的，可以在其上构建应用程序。该软件提供帐户，身份验证，数据库，异步通信以及跨多个CPU核心和/或群集的应用程序调度。由此产生的技术是一种区块链架构，有可能每秒扩展到数百万个事务，注意，只是有可能扩展到数百万个事物。消除了用户费用，并允许快速轻松地部署分散式应用程序。

在安装钱包节点之前，咱们应该先了解一下EOS的架构，下面是EOS的一个模块架构。

nodeos（node + eos = nodeos）-可以使用插件配置以运行节点的核心EOSIO节点守护程序。示例用法是块生产，专用API端点和本地开发。

cleos（cli + eos = cleos）-与区块链交互并管理钱包的命令行界面

keosd（key + eos = keosd）-将EOSIO密钥安全存储在钱包中的组件。

eosio-cpp - eosio.cdt的一部分，它将C++代码编译为WASM并可以生成ABI

安装EOS钱包节点

下面咱们使用二进制文件来构建项目，从源码来构建项目的话，这种操作方式比较复杂，而且很浪费时间，这里不推荐这种方式。

1.各种平台上安装EOS

1.1.在mac平台下安装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.启动节点并对节点进行配置

2.1.启动Keosd

keosd &

 

执行上面这个命令之后，你应该可以看到类似下面这样的输出，按Enter键可以退出来。

2.2.启动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 &

这些设置可实现以下功能：

在开发目录下的eosio目录中使用工作目录进行区块链数据和配置。这里我们分别使用eosio/data和eosio/config

运行Nodeos。此命令加载所有基本插件，设置服务器地址，启用CORS并添加一些合同调试和日志记录。

无限制地启用CORS（*）

在上面的配置中，CORS仅用于开发目的*，您永远不应在可公开访问的节点上启用CORS for *！

3.检查节点的和钱包的情况

3.1.检查节点的情况

运行下面的命令

tail -f nodeos.log

你可以看到终端下面有这些输入

按CNTL + C键退出日志。

3.2.检查钱包的情况

打开shell并运行cleos命令列出可用的钱包

cleos wallet list

你应该看到下面这样的输出

Wallets:
[]

3.3.检查Nodeos末端节点

这将检查RPC API是否正常工作，选择一个。

检查浏览器中chain_api_plugin提供的get_info端点：

http：// localhost：8888 / v1 / chain / get_info

检查相同的事情，但在主机的控制台中

curl http://localhost:8888/v1/chain/get_info

读到这里，小伙伴们学会怎么安装了吗？
