以下是在linux环境下安装以太坊c++客户端，搭建私有链过程的记录

基于Ubuntu16.04.5系统

 

一、下载cpp-ethereum源码

1、安装git

输入 sudo apt-get install git

2、下载cpp-ethereum源码

git clone --recursive https://github.com/ethereum/cpp-ethereum.git

 

二、安装CMake

输入 sudo apt-get install cmake

 

三、安装依赖项

进入cpp-ethereum文件夹

输入 scripts/install_deps.sh

 

四、编译

依次输入命令

mkdir build

cd build

cmake ..

make

 

五、安装以太坊控制台etheconsole

1、下载安装npm

 sudo apt-get install npm

 

2、安装用于安装nodejs的模块n

sudo npm install -g n

 

3、安装最新版nodejs

sudo n latest

 

输入 node -v 可查看node版本

 

4、安装ethconsole

 

由于直接使用sudo npm install -g ethereum-console 出现错误

 

于是按照npmjs官方文档中的步骤进行操作:

 

为全局安装创建一个目录：

mkdir ~/.npm-global

 

配置npm以使用新的目录路径：

npm config set prefix '~/.npm-global'

 

打开或创建一个?/ .profile文件并添加以下行：

export PATH=~/.npm-global/bin:$PATH

 

回到命令行，更新系统变量：

source ~/.profile

 

安装ethconsole

npm install -g ethereum-console

 

输入ethconsole出现

ethconsole的命令可以使用则说明安装成功了

 

六、创建创世区块文件

在cpp-ethereum/build/aleth文件夹创建创世区块文件genesis.json

{
    "sealEngine": "Ethash",
    "params": {
            "accountStartNonce": "0x00",
            "frontierCompatibilityModeLimit": "0xffffffff",

    }
}

 

七、创建私有链

1、在cpp-ethereum/build/aleth文件夹下

创建一个文件夹ipctest

 

2、打开终端，进入cpp-ethereum/build/aleth

输入 ./aleth --config genesis.json -m on --network-id 1108 --ipc --listen 30307 --port 30307 -d ipctest --private "myPrivateChain"

私有链启动，开始挖矿

 

3、ipctest文件夹中出现geth.ipc文件

 

八、使用控制台连接私有链

打开一个新的终端

输入 ethconsole cpp-ethereum/build/aleth/ipctest/geth.ipc

出现下图情况说明连接成功
