EOS项目编译及操作入门
本次EOS项目编译操作是在mac上安装的的centos7进行的，可能是虚拟机的问题，本次编译时间较长。下面是本次操作的整个流程。
一、虚拟机安装：具体安装步骤省略，看资料需要我分配了8G内存和50G硬盘，参见下图配置
二、首先需要到github上下载相应的代码，下载地址为：https://github.com/EOSIO/eos 下载前先安装git，安装命令：yum install -y git，安装完成后进入需要保存的硬盘路径下载代码，git clonehttps://github.com/EOSIO/eos --recursive
三、进入eos， ./eosio_build.sh编译，此时会报错：
eos/scripts/eosio_build_centos.sh:行98: /opt/rh/devtoolset-7/enable: 没有那个文件或目录
这时需要安装一些软件，命令如下：
sudo yum -y --enablerepo=extras install centos-release-scl
sudo yum install -y devtoolset-7
sudo yum install -y python33.x86_64
四、使用 ./eosio_build.sh编译，由于下载软件较多，依赖网络速度。
五、编译中出现下载mongodb无法下载问题，试过几个网络都无法下载，最终解决办法是修改编译脚本，由于我的是centos系统，所以修改的是eos/scripts/eosio_build_centos.sh，修改内容如下
六、当出现这个表示编译通过
七、按上面流程启动mongodb， 设置path，然后测试编译结果
/home/lz/opt/mongodb/bin/mongod -f /home/lz/opt/mongodb/mongod.conf &
source /opt/rh/python33/enable
export PATH=${HOME}/opt/mongodb/bin:$PATH
cd /data/blockchain/eos/build; make test
八、编译后分三个程序
-Cleos，它是一个命令行程序。在前端使用EOS是通过Cleos输入命令，给EOS下达指令。
-Nodeos，其实它就是挖矿客户端。在启动Nodeos之后，它自然就会产生区块。
-Keosd，它是在后端启动。它的目的主要是管理钱包，可以创建私钥。
九、启动nodeos服务，./nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::account_history_api_plugin
十、帐户与钱包是EOS中两个不同的概念，钱包管理所有密钥，帐户是实现用户权限管理，通过权重与阈值来管理不同的权限，系统默认有owner和active权限。
[lz@localhost cleos]$ ./cleos get account lz
{
"account_name": "lz",
"permissions": [{
"perm_name": "active",
"parent": "owner",
"required_auth": {
"threshold": 1,
"keys": [{
"key": "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
"weight": 1
}
],
"accounts": []
}
},{
"perm_name": "owner",
"parent": "",
"required_auth": {
"threshold": 1,
"keys": [{
"key": "EOS55pK2pN6vBoZrLdrfmKzU7r4xSuAARtekgKxTuiyfjL29VBE8r",
"weight": 1
}
],
"accounts": []
}
}
]
}
十一、创建钱包
[lz@localhost cleos]$ ./cleos wallet createCreating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5HwWAavqhVRRLKWPLeRxoXEZTfAWHzAaHR5EfgsMxEPqLzLdjLs"
十二、生成公私钥
[lz@localhost cleos]$ ./cleos create key
Private key: 5JYRVnqRBhZUt4SBqBcU3jx53iNFZaWGXrLHiPX3RH39i3DXkYZ
Public key: EOS55pK2pN6vBoZrLdrfmKzU7r4xSuAARtekgKxTuiyfjL29VBE8r
十三、导入私钥
[lz@localhost cleos]$ ./cleos wallet import 5JYRVnqRBhZUt4SBqBcU3jx53iNFZaWGXrLHiPX3RH39i3DXkYZ
imported private key for: EOS55pK2pN6vBoZrLdrfmKzU7r4xSuAARtekgKxTuiyfjL29VBE8r
[lz@localhost cleos]$ ./cleos wallet keys
[[
"EOS55pK2pN6vBoZrLdrfmKzU7r4xSuAARtekgKxTuiyfjL29VBE8r",
"5JYRVnqRBhZUt4SBqBcU3jx53iNFZaWGXrLHiPX3RH39i3DXkYZ"
],[
"EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
"5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"
]
]
十四、创建帐户，
lz@localhost cleos]$ ./cleos create account eosio lz EOS55pK2pN6vBoZrLdrfmKzU7r4xSuAARtekgKxTuiyfjL29VBE8r EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

十五、部署合约

十六、合约调用
[lz@localhost cleos]$ ./cleos push action eosio.token create '["eosio","1000000000.00000 EOS",0,0,0]' -p eosio.token
executed transaction: 20a9e37a1c2197b4795d4d6dc8a8455f4df638ebf2ad3d0acc99ddec7500f26e 248 bytes 104448 cycles
# eosio.token <= eosio.token::create {"issuer":"eosio","maximum_supply":"1000000000.00000 EOS","can_freeze":0,"can_recall":0,"can_whiteli...
十七、发币给用户，发币时需要小数点后的位数与创建币时一样，否则会报Error 3030000的错误
[lz@localhost cleos]$ ./cleos push action eosio.token issue '["lz","100.0000 EOS","memo"]' -p eosio
Error 3030000: transaction validation exception
Ensure that your transaction satisfy the contract's constraint!
Error Details:

十八、货币转帐
[lz@localhost cleos]$ ./cleos push action eosio.token transfer '["lz","eosio.token","25.00000 EOS","m"]' -p lz
executed transaction: bf36c33f27b3bd82a0495f3721c780c94ffd690c9031477f493202140f5d37ae 256 bytes 110592 cycles
