区块链数据的存储位置
不同的操作系统， block数据默认保存的位置也不同：
• Linux: ~/.local/share/eosio/nodeos/data
Eos 编译成功会生成可执行文件
eos@eos-virtual-machine:/usr/local/eosio/bin$ ls
cleos eosio-abigen eosiocpp eosio-launcher eosio-s2wasm eosio-wast2wasm keosd nodeos
eos@eos-virtual-machine:/usr/local/eosio/bin$ ls /home/eos/neweos/eos/build/programs/
cleos CMakeFiles cmake_install.cmake CTestTestfile.cmake eosio-abigen eosio-launcher keosd Makefile nodeos
说明：/home/eos/neweos 这个是安装eos目录
Cleos wallet 使用
• 需要明白为什么需要创建钱包
• 需要明白钱包和账户之间的关系

eos的build目录里生成的可执行程序很多，常用到的：
• nodeos ：通过配置不同插件，启动节点，同步EOS网络数据或者自己生成块，也可作为API节点供调用
• keosd：管理钱包，钱包中包含EOS公私钥对信息
• cleos：命令行交互接口，连接钱包与EOS网络，执行查看网络信息，推送交易信息，部署智能合约等
• eosiocpp：编译智能合约，生成wasm文件及abi文件
根据官网的说明： 无法eos 类似linux kernel， 插件就是我们kernel的 驱动， 所以我们在使用的时候也需要来配置驱动也就是eos描述的插件
