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
。
xcode : https://developer.apple.com/xcode/
homebrew : https://brew.sh
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 2/35 Test #2: validate_simple.token_abi ............ Passed 0.08 sec Start 3: validate_eosio.token_abi ... 34/35 Test #34: restart-scenarios-test-hard_replay ... Passed 151.83 sec Start 35: validate_dirty_db_test 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: */* > < HTTP/1.1 200 OK < Connection: close < Content-Length: 529 < Content-type: application/json < Server: WebSocket++/0.7.0 < {"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_num": 580, "last_irreversible_block_num": 579, "last_irreversible_block_id": "000002436a1baaeb366b55995ddad7de0822f177d60a8c6e336e3f5fcb18ecc5", "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。
