EOS Dapp开发（1）-基于Docker的开发环境搭建
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/^#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 98476 -rwxr-xr-x. 1 root root 568 Jun 12 00:00 nodeosd.sh -rwxr-xr-x. 1 root root 2520080 Jun 12 00:01 eosio-s2wasm -rwxr-xr-x. 1 root root 698824 Jun 12 00:01 eosio-wast2wasm -rwxr-xr-x. 1 root root 5652336 Jun 12 00:03 eosio-launcher -rwxr-xr-x. 1 root root 7710032 Jun 12 00:03 keosd -rwxr-xr-x. 1 root root 27580032 Jun 12 00:03 eosio-abigen -rwxr-xr-x. 1 root root 48145016 Jun 12 00:03 nodeos -rwxr-xr-x. 1 root root 8510256 Jun 12 00:03 cleos drwxr-xr-x. 3 root root 4096 Jun 13 11:00 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
1 Options: 2 -h,--help Print this help message and exit 3 -u,--url TEXT=http://localhost:8888/ 4 the http/https URL where nodeos is running 5 --wallet-url TEXT=http://localhost:8900/ 6 the http/https URL where keosd is running 7 -r,--header pass specific HTTP header; repeat this option to pass multiple headers 8 -n,--no-verify don\'t verify peer certificate when using HTTPS 9 -v,--verbose output verbose actions on error 10 --print-request print HTTP request to STDERR 11 --print-response print HTTP response to STDERR 12 13 Subcommands: 14 version Retrieve version information 15 create Create various items, on and off the blockchain 16 get Retrieve various items and information from the blockchain 17 set Set or update blockchain state 18 transfer Transfer EOS from account to account 19 net Interact with local p2p network connections 20 wallet Interact with local wallet 21 sign Sign a transaction 22 push Push arbitrary transactions to the blockchain 23 multisig Multisig contract commands 24 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。
