在Ubuntu上安装以太坊主要分为以下几个步骤:
1. 安装基本依赖和工具 安装Git: ```bash sudo apt install y git ``` 安装Node.js: ```bash curl sL https://deb.nodesource.com/setup_14.x | sudo E bash sudo aptget install y nodejs ``` 安装npm: ```bash sudo apt install y npm ```
2. 安装以太坊客户端(Geth) 下载Geth: ```bash cd /opt mkdir geth cd geth wget c 'https://gethstore.blob.core.windows.net/builds/gethalltoolslinuxamd641.9.18f5382591.tar.gz' tar zxvf gethalltoolslinuxamd641.9.18f5382591.tar.gz ``` 配置环境变量: ```bash echo 'export PATH=$PATH:/opt/geth/gethlinuxamd641.9.18f5382591/gethlinuxamd641.9.18f5382591/bin' >> ~/.bashrc source ~/.bashrc ```
3. 安装Truffle和Ganache 安装Truffle: ```bash npm install g truffle ``` 安装Ganache: ```bash npm install g ganachecli ```
4. 安装Solidity编译器 安装Solc: ```bash npm install g solc ```
5. 搭建私有链(可选) 创建创世区块文件: ```bash mkdir p ~/ethereum/privatechain cd ~/ethereum/privatechain touch genesis.json ``` 编辑genesis.json: ```json { config: { chainId: 12345, homesteadBlock: 0, eip155Block: 0, eip158Block: 0 }, difficulty: 400 gasLimit: 2100000 alloc: {} } ``` 启动私有链: ```bash geth datadir ~/ethereum/privatechain init genesis.json geth datadir ~/ethereum/privatechain networkid 12345 console ```
6. 安装Ethminer(挖矿) 添加以太坊存储库: ```bash sudo addaptrepository ppa:ethereum/ethereum sudo aptget update ``` 安装Ethminer: ```bash sudo aptget install ethminer ``` 开始挖矿: ```bash ethminer G ```
