搭建EOS本地测试环境

本文主要参照EOS的官方文档 https://developers.eos.io/eosio-nodeos/docs

Getting the Code

获取EOS源码：

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

大概需要等几分钟，等代码clone完成。

Build Options

编译选项
EOS可以用多种途径编译：

• Autobuild Script
• Docker
• Manual Build

编译过程会把生成的内容放在 eos/build 目录，生成的可执行文件放在 eos/build/programs 目录。

系统配置要求
所有系统上，都需要满足：
7GB RAM free required
20GB Disk free required

否则执行编译脚本时报错：

$ ./eosio_build.sh

调整虚拟机内存到8GB，继续下面的编译过程

开始编译

这里采用 Autobuild Script 方式进行编译（执行自动脚本 eosio_build.sh 会自动检查需要的依赖并下载依赖，然后自动执行编译脚本完成编译，否则采用手动编译的话需要手动下载所有的依赖，然后手动执行编译脚本）：

cd eos
./eosio_build.sh

执行命令后会检查缺少的依赖，并询问是否安装依赖，选择yes后会下载安装依赖，并继续进行编译。

—————————————————- 分割线 —————————————————-

执行完上述命令后等待自动编译就行了，这里接下去是看下自动编译过程中输出的log，在这里只展示关键的部分，来大概了解下整体的过程:

    EOSIO has been successfully built. 12:35:31

    To verify your installation run the following commands:

    export PATH=${HOME}/opt/mongodb/bin:$PATH
    /home/yzp/opt/mongodb/bin/mongod -f /home/yzp/opt/mongodb/mongod.conf &
    cd /home/yzp/blockchain/EOS/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

根据上面自动编译时输出的log可以看到自动编译也和手动编译时需要先安装依赖一样(详见：https://developers.eos.io/eosio-nodeos/docs/clean-install-ubuntu-1604-and-higher )，先安装一些必须的依赖的dpkg，再安装Boost ， mongo-cxx-driver ，secp256k1-zkp ，以及重新编译安装llvm和clang以包含进WASM(因为默认安装的llvm和clang没有WASM)。 依赖安装完成后再编译EOS。

整个过程大概需要几个小时。

Build Validation(Optionally, 可选的，不做这一步也可以)

编译完成之后，可以运行一些测试用例，来验证编译是否成功。
按照下列步骤进行：
start mongod

On Linux platforms:

~/opt/mongodb/bin/mongod -f ~/opt/mongodb/mongod.conf &

On MacOS:

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

run make test
all platforms:

cd build
make test

验证成功后会看到如下输出：

说明全部测试用例通过。

Install Executables

上面编译完成后，在 eos/build/programs/nodeos 路径下已经有nodeos可执行程序了，进入该目录直接执行

./nodeos

即可启动程序，但是为了便于开发者使用，可以把 build 下的内容安装到 /usr/local 路径下(系统预设的可执行文件路径)，类似于windows系统下把可执行程序添加到path环境变量中，这样就可以随处运行 nodeos 命令即可启动程序了。

安装完成。现在，随便在哪个位置，比如是在桌面，打开命令行，输入nodeos也能启动程序了！

Configuration

nodeos有两种方式可以进行配置运行参数，命令行 和 配置文件config.ini。每一个命令行中的参数都对应配置文件中的一个设置，如：–plugin eosio::chain_api_plugin 对应config.ini配置文件中的 plugin = eosio::chain_api_plugin 。 如果运行时想采用自定义的配置文件，可以执行：

$ nodeos --config path/to/config.ini

1. 命令行( command line interface (CLI) options )

所有的命令行选项可以执行

$ nodeos --help

进行查看

2. 配置文件( configuration file )

config.ini 的位置在:
Mac OS:

~/Library/Application Support/eosio/nodeos/config

Linux:
