柚子EOS开发环境搭建

in #blockchain • 6 years ago

本文主要介绍如何构建在EOS平台运行的DApp开发环境。

EOSIO构成组件

EOSIO是由三个component组成的。

  • nodeos:管理区块链节点的组件。
  • keosd：管理钱包的组件。
  • cleos：控制区块链和钱包CLI工具。

安装EOSIO

此文档以MacOS Darwin 10.12为基准。

在EOSIO的github库下载源码。

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

要安装xcode和homebrew代码。如果还没有安装的情况，先设置xcode和homebrew。

源代码包含构建脚本及构建实现。

$ cd eos
$ ./eosio_build.sh

如果成功的话，就会出现下面的信息。

[100%] Linking CXX executable unit_test

[100%] Built target unit_test

EOSIO has been successfully built. 00:11:21

To verify your installation run the following commands:

/usr/local/bin/mongod -f /usr/local/etc/mongod.conf &

cd /Users/scion/git/eos/build; make test

For more information:

EOSIO website: https://eos.io

EOSIO Telegram channel @ https://t.me/EOSProject

EOSIO resources: https://eos.io/resources/

EOSIO Stack Exchange: https://eosio.stackexchange.com

EOSIO wiki: https://github.com/EOSIO/eos/wiki

解决问题

  • 如果build过程中出现这样的error时:
CMake Error at /usr/local/Cellar/cmake/3.11.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
 Failed to find Gettext libintl (missing: Intl_INCLUDE_DIR)
Call Stack (most recent call first):
 /usr/local/Cellar/cmake/3.11.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
 /usr/local/Cellar/cmake/3.11.3/share/cmake/Modules/FindIntl.cmake:47 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
 programs/cleos/CMakeLists.txt:29 (find_package)

应该是homebrew的gettext连接到了不正确的版本，更改连接信息就可以了:

$ brew link gettext — force

在环境变量文件(~/.profile)添加gettoxt path:

export PATH=”/usr/local/opt/gettext/bin:$PATH”

参考：https://github.com/EOSIO/eos/issues/2174

  • 也有可能发生这种情况：
Mac OS 10.13.3 build error “path mongo-cxx-driver already exists”

这样解决：

sudo rm -rf /tmp/mongo*
cd /path/to/eos
rm -rf build/
git pull
git submodule update — init — recursive
./eosio_build.sh

参考：https://github.com/EOSIO/eos/issues/3197

验证

安装顺利完成。为了验证，执行下测试脚本。

$ /usr/local/bin/mongod -f /usr/local/etc/mongod.conf &

$ cd build/

$ make test

Running tests...

Test project /Users/scion/git/eos/build

Start  1: test_cypher_suites

1/35 Test  #1: test_cypher_suites ...................   Passed    0.04 sec

Start  2: validate_simple.token_abi

35/35 Test #35: validate_dirty_db_test ...............   Passed    4.42 sec

100% tests passed, 0 tests failed out of 35

下面完成安装：

$ cd build

$ sudo make install

运行EOSIO

试着运行EOSIO的组件吧。这是为了构建开发环境，所以可以先用一个节点。

nodeos

用带有option的命令直接执行就行了

$ nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin

其中：

  • e : 区块生成
  • p eosio : 区块生产者名称
    — plugin eosio::chain_api_plugin : 区块链相关API插件
    — plugin eosio::history_api_plugin : 历史记录相关API插件

可以用配置文件替换参数。

  • config file位置: ~/Library/Application Support/eosio/nodeos/config/config.ini
  • 当nodeos第一次运行时，该文件自动生成。
$ vi ~/Library/Application\ Support/eosio/nodeos/config/config.ini
 
...
# enable-stale-production = false
enable-stale-production = true
...
# producer-name =
producer-name = eosio
...
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
...

执行nodeos :

$ nodeos

如果运行正常，可以看到在控制台上0.5秒生成block的信息。

为了确认nodeos是否正常运行，让我们试试应用程序API接口。

在运行于8888端口的应用软件服务上试试HTTP Request：

$ curl -k -v 'http://127.0.0.1:8888/v1/chain/get_info' -X GET
 
Note: Unnecessary use of -X or --request, GET is already inferred.
* Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 8888 (#0)
> GET /v1/chain/get_info HTTP/1.1
> Host: 127.0.0.1:8888
> User-Agent: curl/7.54.0
> Accept: */*

{"server_version":"012dc012","chain_id":"cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f","head_block_num":363,"last_irreversible_block_num":362,"last_irreversible_block_id":"0000016ad0238cef2f6a8de2098115ba155cbbc535122912a7a62f66097adbd6","head_block_id":"0000016b8cbb9154a759f2e61968fc1069fcf0ef9468886614d0538a97d96c61","head_block_time":"2018-06-12T07:10:59","head_block_producer":"eosio","virtual_block_cpu_limit":287075,"virtual_block_net_limit":1506023,"block_cpu_limit":199900,"block_net_limit":1048576}

或是利用cleos命令执行。

$ cleos get info
{
  "server_version": "012dc012",
  "chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",

  "head_block_id": "00000244e6923239c0649ddada0dd47a2df80df13fa825275df9ddac975e6162",
  "head_block_time": "2018-06-12T07:12:48",
  "head_block_producer": "eosio",
  "virtual_block_cpu_limit": 356561,
  "virtual_block_net_limit": 1871085,
  "block_cpu_limit": 199900,
  "block_net_limit": 1048576
}

keosd

同样用带有option的命令直接执行就行了

$ keosd — http-server-address=127.0.0.1:8900
  • http-server-address : REST API，nodeos默认端口是8888。cleos默认端口考虑使用8900，URL不可用。

只能通过替换keosd配置文件选项来运行。

  • 配置文件位置：~/eosio-wallet/config.ini。
  • 第一次keosd操作，文件自动生成。
$ vi ~/eosio-wallet/config.ini
 
# http-server-address = 127.0.0.1:8888
http-server-address = 127.0.0.1:8900

执行keosd:

$ keosd

在运行于8900端口的应用软件服务上试试HTTP Request：

$ curl -k -v ‘http://127.0.0.1:8900/v1/wallet/list_wallets' -X GET

Note: Unnecessary use of -X or — request, GET is already inferred.
* Trying 127.0.0.1…
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 8900 (#0)
> GET /v1/wallet/list_wallets HTTP/1.1
> Host: 127.0.0.1:8900
> User-Agent: curl/7.54.0
> Accept: */*
>
< HTTP/1.1 200 OK
< Connection: close
< Content-Length: 2
< Content-type: application/json
< Server: WebSocket++/0.7.0
<
[]

或者使用cleos命令运行：

$ cleos wallet list
Wallets:
[]

nodeos和keosd可以正常工作，现在可以使用EOSIO服务了。

参考文件是EOSIO官方wiki文档，参考了本地环境的安装。
