随着EOS主网的上线，相信基于EOS的Dapp开发会越来越多，查阅了很多资料相关的开发资料都不是很多，只能自己摸索，按照网上仅有的几篇教程，先git clonehttps://github.com/EOSIO/eos –recursive，然后慢慢编译，然后就陷入了各种报错、各种奔溃的场景。为什么编译不报错的环境都是别人的！！！！。
没办法只能另想办法，突然想到Docker这个神一样的东西（之前的随笔里有一篇是redhat 7.2 内网安装docker），去Docker hub上搜EOS，果然有....https://hub.docker.com/r/eosio/,选取eosio/eos，然后开工，这个镜像不大，200多M，下载之后
1 docker pull eosio/eos 2 docker images 3 docker.io/eosio/eos latest 01fdb2b0f454 34 hours ago 245 MB
下载好了，启动镜像：
1 docker run --name nodeos -v /home/docker/dockerdata/eosdata:/opt/eos/bin/data-dir -p 8888:8888 -p 9876:9876 -p10023:22 -t eosio/eos nodeosd.sh 2 3 36039ms thread-0 chain_plugin.cpp:206 plugin_initialize ] initializing chain plugin 4 36039ms thread-0 chain_plugin.cpp:381 plugin_initialize ] Starting up fresh blockchain with default genesis state. 5 CHAINBASE: Failed to pin chainbase shared memory (of size 8192 MB) in RAM.

有两个Failed，我测试下来暂时未发现有什么影响，暂且跳过不管（网上也有人说至少需要8G，这个后续有问题我会再更新处理）。有人反馈界面会卡在这里，其实Ctrl + C退出也没关系，容器还是会一直运行。
docker exec -it nodeos /bin/bash 进入容器，
ps：通过上述方式进入容器不是很方便，这里提供一种方式给容器安装ssh服务（虽然不推荐这么做，为了省事还是....）
#进入容器后执行如下代码 #对于不能上网的需要设置代理的需要将代理两行放开 #proxy=192.168.1.100:3129 && #export http_proxy=http://${proxy} && echo 'root:root' |chpasswd && apt-get update && apt-get -y install openssh-server && sed -ri 's/^#PermitRootLogins+.*/PermitRootLogin yes/' /etc/ssh/sshd_config && sed -ri 's/UsePAM yes/#UsePAM yes/g' /etc/ssh/sshd_config && /etc/init.d/ssh start
进入 /opt/eosio/bin，EOS相关的命令都在这里
cd /opt/eosio/bin ls -rtl

核心关注的命令是cleos、nodeos、keosd。
cleos：命令行程序，通过命令行执行相应命令，如钱包、转账等操作

nodes：是一个挖矿的客户端，启动之后会开始挖矿，容器启动命令里nodeosd.sh，就是启动了一个nodes。
keosd：主要和钱包相关。
至此基于Docker的Eos环境搭建完毕，下一篇将开始EOS Dapp开发。
