手把手教你厘清EOS开发环境搭建来龙去脉

手把手教你厘清EOS开发环境搭建来龙去脉

黎跃春(愿码ChainDesk.CN) 发布在 技术指南 55487

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。

  • 操作系统
  • EOS 版本

 

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。
liyuechun:eos yuechunli$ ./eosio_build.sh darwin full
liyuechun:eos yuechunli$ ls
CMakeLists.txt		debian			ring.dot
CMakeModules		docs			ring.png

EOS.IO has been successfully built. 0:11:48

To verify your installation run the following commands:

/usr/local/bin/mongod -f /usr/local/etc/mongod.conf & cd /Users/liyuechun/eos/build; make test

For more information: EOS.IO website: https://eos.io EOS.IO Telegram channel @ https://t.me/EOSProject EOS.IO resources: https://eos.io/resources/ EOS.IO wiki: https://github.com/EOSIO/eos/wiki

EOS附带的可执行程序:
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: 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。

generating default genesis file /Users/liyuechun/Library/Application Support/eosio/nodeos/config/genesis.json表示创建了一个nodeos节点文件夹。

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:

# Track only transactions whose scopes involve the listed accounts. Default is to track all transactions. (eosio::account_history_plugin)

# MongoDB URI connection string, see: https://docs.mongodb.com/master/reference/connection-string/. If not specified then plugin is disabled. Default database 'EOS' is used if not specified in URI. (eosio::mongo_db_plugin) # mongodb-uri =

# The actual host:port used to listen for incoming p2p connections. (eosio::net_plugin) p2p-listen-endpoint = 0.0.0.0:9876

# The public endpoint of a peer node to connect to. Use multiple p2p-peer-address options as needed to compose a network. (eosio::net_plugin) # p2p-peer-address =

# The name supplied to identify this node amongst the peers. (eosio::net_plugin) agent-name = "EOS Test Agent"

# Can be 'any' or 'producers' or 'specified' or 'none'. If 'specified', peer-key must be specified at least once. If only 'producers', peer-key is not required. 'producers' and 'specified' may be combined. (eosio::net_plugin) allowed-connection = any

# Optional public key of peer allowed to connect. May be used multiple times. (eosio::net_plugin) # peer-key =

# Tuple of [PublicKey, WIF private key] (may specify multiple times) (eosio::net_plugin) # peer-private-key =

# Log level: one of 'all', 'debug', 'info', 'warn', 'error', or 'off' (eosio::net_plugin) log-level-net-plugin = info

# Maximum number of clients from which connections are accepted, use 0 for no limit (eosio::net_plugin) max-clients = 25

# number of seconds to wait before cleaning up dead connections (eosio::net_plugin) connection-cleanup-period = 30

# True to require exact match of peer network version. (eosio::net_plugin) network-version-match = 0

# number of blocks to retrieve in a chunk from any individual peer during synchronization (eosio::net_plugin) sync-fetch-span = 100

# Enable block production, even if the chain is stale. (eosio::producer_plugin) enable-stale-production = true

# Percent of producers (0-100) that must be participating in order to produce blocks (eosio::producer_plugin) required-participation = 33

# ID of producer controlled by this node (e.g. inita; may specify multiple times) (eosio::producer_plugin) producer-name = eosio

# Tuple of [public key, WIF private key] (may specify multiple times) (eosio::producer_plugin) private-key = ["EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV","5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"]

# The path of the wallet files (absolute path or relative to application data dir) (eosio::wallet_plugin) wallet-dir = "."

# Timeout for unlocked wallet in seconds. Wallets will automatically lock after specified number of seconds of inactivity. Activity is defined as any wallet command e.g. list-wallets. (eosio::wallet_plugin) # unlock-timeout =

# eosio key that will be imported automatically when a wallet is created. (eosio::wallet_plugin) # eosio-key =

# Plugin(s) to enable, may be specified multiple times # Load the block producer plugin, so you can produce blocks plugin = eosio::producer_plugin # Wallet plugin plugin = eosio::wallet_api_plugin # As well as API and HTTP plugins plugin = eosio::chain_api_plugin plugin = eosio::http_plugin

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。
