EOS基础

1.config.ini初始化
enable-stale-production = true
producer-name = eosio
plugin = eosio::chain_api_plugin

2.mac退出节点程序(stop.sh)
pid=`ps -A | grep nodeos | awk '{print $1}' | head -1`
kill  $pid
echo "stop eos finished"

killall keosd nodeos || true

3.rpc调用:
build/programs/cleos/cleos get info
{

  "chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",

5.钱包文件路径
/Users/xj/eosio-wallet

6.重新编译
brew remove --force boost
brew remove --force llvm
cd /path/to/eos
rm -rf build/
git pull
git submodule update --init --recursive
./eosio_build.sh

export LDFLAGS="-L/usr/local/opt/boost@1.57/lib"
export CPPFLAGS="-I/usr/local/opt/boost@1.57/include"

7.创建帐号提示:system contract must first be initialized
cleos set contract eosio /Users/xj/code/safecode.contracts/build/contracts/eosio.bios -p eosio

8.eosio目录结构:
8.1:config.ini是配置文件.
8.2:data文件夹是区块数据存储位置,它包括blocks和state两个目录.
8.3:blocks是区块链日志文件,保存区块链的区块数据.其中reversible目录下存放的是内在映射的可逆区块文件,该文件大小是可配置的.
8.4:state目录下存放的是状态数据库文件,也是内在映射的方式,其大小是可配置的.

9.脚本
tutorials/bios-boot-tutorial/bios-toot-tutorial.py

10.系统内部初始创建三个帐户:eosio,eosio.null,eosio.prods
