EOS本地节点搭建（docker）——东科教育 - 好文

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
<https://blog.csdn.net/m0_37722557/article/details/80652078>

或者根据官方文档：

        docker: Get Docker CE for Ubuntu
<https://link.juejin.im/?target=https%3A%2F%2Flink.zhihu.com%2F%3Ftarget%3Dhttps%253A%2F%2Fdocs.docker.com%2Finstall%2Flinux%2Fdocker-ce%2Fubuntu%2F>

        docker-compose: Install Docker Compose
<https://link.juejin.im/?target=https%3A%2F%2Flink.zhihu.com%2F%3Ftarget%3Dhttps%253A%2F%2Fdocs.docker.com%2Fcompose%2Finstall%2F%2523install-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
<https://link.juejin.im/?target=https%3A%2F%2Flink.zhihu.com%2F%3Ftarget%3Dhttps%253A%2F%2Fgithub.com%2FEOSLaoMao%2FDocumentation%2Fblob%2Fmaster%2Fzh-CN%2FTechnicalWhitePaper-v2.md>

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
