最近对去中心化交易感兴趣，于是想摆弄一下EOS。进入它的官网（https://eos.io/），看到现在已经发布到DAWN3.0了，于是去github下载安装最新版（https://github.com/EOSIO/eos），想自己安装一个本地环境。
按照它的说明一步步设置，我安装环境是Ubuntu16.04，下面执行都没有问题
git clone https://github.com/eosio/eos --recursive
cd eos
./eosio_build.sh
等了几分钟，显示编译成功，可以运行了
按照单节点测试运行 Creating and launching a single-node testnet
进入到 eos/build/programs/eosiod 目录
先运行 eosiod 然后ctrl+c 终止，发现没有说明书上的data-dir目录生成，然后一通找，终于在
eos/build/etc/eosio/node_00目录发现了config.ini
下一步把整段内容添加到config.ini的后面
//# Load the testnet genesis state, which creates some initial block producers with the default key
genesis-json = /path/to/eos/source/genesis.json
// # Enable production on a stale chain, since a single-node test chain is pretty much always stale
enable-stale-production = true
//# Enable block production with the testnet producers
producer-name = inita
producer-name = initb
producer-name = initc
producer-name = initd
producer-name = inite
producer-name = initf
producer-name = initg
producer-name = inith
producer-name = initi
producer-name = initj
producer-name = initk
producer-name = initl
producer-name = initm
producer-name = initn
producer-name = inito
producer-name = initp
producer-name = initq
producer-name = initr
producer-name = inits
producer-name = initt
producer-name = initu
//# Load the block producer plugin, so you can produce blocks
plugin = eosio::producer_plugin
//# Wallet plugin
plugin = eosio::wallet_api_plugin
//# As well as API and HTTP plugins
plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin
再次运行eosiod
报告一堆错误信息，反复检查和搜索之后，终于找到原因
enable-stale-production 项目有两条设置，注释掉=false那一条
再运行eosiod
这次报告genesis-json文件找不到，看看上面的内容
genesis-json = /path/to/eos/source/genesis.json
确实不对，把它改为
genesis-json = /home/ls/eos/genesis.json
终于看到了
------ NEW CHAIN ------
Welcome to EOSIO!
但是，稳定下来后一直输出
556500ms thread-0 producer_plugin.cpp:229 block_production_loo ] Not producing block because it isn't my turn, its eosio
557000ms thread-0 producer_plugin.cpp:229 block_production_loo ] Not producing block because it isn't my turn, its eosio
557500ms thread-0 producer_plugin.cpp:229 block_production_loo ] Not producing block because it isn't my turn, its eosio
558000ms thread-0 producer_plugin.cpp:229 block_production_loo ] Not producing block because it isn't my turn, its eosio
显然不能生成区块链，没有看到说明书中的generated block类似的信息
这次查了很久，问题依然，最后从错误信息中分析，难道是需要一个eosio用户？
于是试试看增加了一行配置 producer-name = eosio
这次输出：
eosio generated block 736a4611... #1 @ 2018-03-21T03:30:52.000 with 0 trxs
eosio generated block 639d8722... #2 @ 2018-03-21T03:30:52.500 with 0 trxs

ohyeah！成功了。
