EOS本地节点搭建（docker）——东科教育

1. 安装 Docker 和 docker-compose

       上一篇文章有详细步骤：EOS本地测试节点搭建---Docker 安装

 

        或者根据 官方文档：

        docker: Get Docker CE for Ubuntu

        docker-compose: Install Docker Compose

 

2. EOSIO Dev Docker image

EOSIO Dev Docker镜像是为本地开发而设计的EOSIO软件的编译版本。

从存储库中提取图像：（下载过程比较慢）

docker pull eosio/eos-dev

并启动EOSIO节点：

sudo docker run --rm --name eosio -d -p 8888:8888 -p 9876:9876 -v /tmp/work:/work -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev  /bin/bash -c "nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::wallet_plugin --plugin eosio::producer_plugin --plugin eosio::history_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:8888 --access-control-allow-origin=* --contracts-console"

检查其工作：

sudo docker logs --tail 10 eosio

你的输出应该类似于这个：

恭喜！您在Docker容器中运行了一个非常简单的单节点区块链！

还要在浏览器中查看该地址以检查RPC接口是否正常工作： http://localhost:8888/v1/chain/get_info

您应该看到类似于以下内容的消息：

{
    "server_version": "0961a560",
    "chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
    "head_block_num": 13780,
    "last_irreversible_block_num": 13779,
    "last_irreversible_block_id": "000035d36e1ca29ba378081c574ab3b5ab4214ba29754dd42b512690a9f03e80",
    "head_block_id": "000035d4165c9225d7a04822d142fbcb15f997a6f2571dc7bae8437dea782205",
    "head_block_time": "2018-05-23T16:30:54",
    "head_block_producer": "eosio",
    "virtual_block_cpu_limit": 100000000,
    "virtual_block_net_limit": 1048576000,
    "block_cpu_limit": 99900,
    "block_net_limit": 1048576
}

其中 server_version 表示当前服务器运行的 eos 代码版本，其取值为代码的最近一条 commit log 前 8 个字符。对应的正是 build docker image 的时候 master 代码的最新 commit。

head_block_num 表示最新的区块编号，可以理解为区块高度。

last_irreversible_block_num 表示不可逆区块的最大编号，关于这两个的具体区别，可以参见 EOS 技术白皮书中文版

head_block_time 是最新区块的生成时间。

head_block_producer 则表示由哪个节点产生。由于我们只有一个节点，因此其取值一直是 eosio。

关闭节点

 

docker stop eosio
