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
docker pull eosio/eos
docker images
docker.io/eosio/eos latest 01fdb2b0f454 hours ago MB
下载好了，启动镜像：

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: &&\
#export http_proxy=http://${proxy} &&\
echo 'root:root' |chpasswd &&\
apt-get update &&\
apt-get -y install openssh-server &&\
sed -ri 's/^#PermitRootLogin\s+.*/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
total
-rwxr-xr-x. root root Jun : nodeosd.sh
-rwxr-xr-x. root root Jun : eosio-s2wasm
-rwxr-xr-x. root root Jun : eosio-wast2wasm

-rwxr-xr-x. root root Jun : nodeos
-rwxr-xr-x. root root Jun : cleos
drwxr-xr-x. root root Jun : data-dir
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
Options:
-h,--help Print this help message and exit
-u,--url TEXT=http://localhost:8888/
the http/https URL where nodeos is running
--wallet-url TEXT=http://localhost:8900/
the http/https URL where keosd is running
-r,--header pass specific HTTP header; repeat this option to pass multiple headers
-n,--no-verify don't verify peer certificate when using HTTPS
-v,--verbose output verbose actions on error
--print-request print HTTP request to STDERR
--print-response print HTTP response to STDERR Subcommands:
version Retrieve version information
create Create various items, on and off the blockchain
get Retrieve various items and information from the blockchain
set Set or update blockchain state
transfer Transfer EOS from account to account
net Interact with local p2p network connections
wallet Interact with local wallet
sign Sign a transaction
push Push arbitrary transactions to the blockchain
multisig Multisig contract commands
system Send eosio.system contract action to the blockchain.
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。
