EOSIO本地环境搭建

eos.io的本地环境的搭建主要是参考eos.io在GitHub的Wiki,同时记录一下搭建过程中遇到的坑。

Getting the Code

首先需要获得eos.io的source code,通过以下的命令clone到本地:
git clone https://github.com/EOSIO/eos --recursive
命令行的–recursive这个flag确保克隆eos仓库和它的子模块,如果clone时没有使用这个flag,则通过下面的命令也可以取得子模块:
git submodule update --init --recursive

Building EOSIO

Automated build script

最简单的方法是使用eos的自动编译脚本,自动编译脚本支持以下的系统:

1. Amazon 2017.09 and higher.
2. Centos 7.
3. Fedora 25 and higher (Fedora 27 recommended).
4. Mint 18.
5. Ubuntu 16.04 (Ubuntu 16.10 recommended).
6. MacOS Darwin 10.12 and higher (MacOS 10.13.x recommended).

System Requirements (all platforms)

同时,所有的操作平台,需要满足:

1. 8GB的可用内存
2. 20GB的可用磁盘

如果内存不满足,脚本将会给出提示并且终止当前编译。

Run the build script

cd eos
./eosio_build.sh
脚本会check系统的环境,如果某些依赖不存在,脚本会提示进行安装。
如下是博主在macOS Darwin 10.13.4上运行脚本后出现的依赖不存在情况:

Checking dependencies.
Checking automake ...        automake NOT found.
Checking Libtool ...         Libtool NOT found.
Checking OpenSSL ...         OpenSSL NOT found.
Checking llvm ...        llvm NOT found.
Checking wget ...        wget NOT found.
Checking CMake ...       CMake NOT found.
Checking GMP ...         GMP NOT found.
Checking gettext ...         gettext NOT found.
Checking MongoDB ...         MongoDB NOT found.
Checking Doxygen ...         Doxygen NOT found.
Checking Graphviz ...        Graphviz NOT found.
Checking LCOV ...        LCOV NOT found.
Checking Python3 ...         python3 NOT found.

The following dependencies are required to install EOSIO.

1. automake
2. Libtool
3. OpenSSL
4. llvm
5. wget
6. CMake
7. GMP
8. gettext
9. MongoDB
10. Doxygen
11. Graphviz
12. LCOV
13. Python 3


Do you wish to install these packages?
1) Yes
2) No
#?

build seccess将会出现以下画面:

     _______  _______  _______ _________ _______
    (  ____ \(  ___  )(  ____ \\__   __/(  ___  )
    | (    \/| (   ) || (    \/   ) (   | (   ) |
    | (__    | |   | || (_____    | |   | |   | |
    |  __)   | |   | |(_____  )   | |   | |   | |
    | (      | |   | |      ) |   | |   | |   | |
    | (____/\| (___) |/\____) |___) (___| (___) |
    (_______/(_______)\_______)\_______/(_______)

    EOS.IO has been successfully built. 1:6:15

    To verify your installation run the following commands:

    /usr/local/bin/mongod -f /usr/local/etc/mongod.conf &
    cd /Users/lauyearh/Blockchain/EOS/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

Build validation

可以通过一组测试用例,验证你的编译。
如果是在Linux平台:
~/opt/mongodb/bin/mongod -f ~/opt/mongodb/mongod.conf &
如果是在macOS:
/usr/local/bin/mongod -f /usr/local/etc/mongod.conf &
然后执行以下命令,不管在Linux还是macOS:
cd build
make test
最后出现这样的提示说明测试通过:

100% tests passed, 0 tests failed out of 33

Total Test time (real) = 806.70 sec

Install the executables

通过安装可执行档案,可以在系统中方便操作eos,相当于把cmd写到PATH变量中,但是其实是把内容安装到/usr/local:
cd build
sudo make install

Creating and Launching a Single Node Testnet

运行下面的命令,将启动一个简单的节点:
cd build/programs/nodeos
./nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::account_history_api_plugin
这个时候,默认的config路径,在macOS上是$HOME/Library/Application Support/eosio/nodeos/config,里面包含config.inigenesis.json两个文件。当然,你也可以在启动nodeos时通过–config-dir指定config路径,并且需要建立ini和json两个文件。

总结

博主build时用的是macOS,同时系统配置满足要求,使用自动编译脚本的时候没遇到什么坑,顺利build通过。Source code是master branch,commit id是19227c9b0a095683c1df3668c110cef2d91cbb15
