切换到eos/build/programs/cleos路径下面。
1. 钱包设置
秘钥需要保存好，后面解锁时会用到。
liyuechun:cleos yuechunli$ ./cleos wallet create
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.

2. 为账号部署合约
liyuechun:cleos yuechunli$ ./cleos set contract eosio ../../contracts/eosio.bios -p eosio
liyuechun:cleos yuechunli$ ./cleos set contract eosio ../../contracts/eosio.bios -p eosio

liyuechun:cleos yuechunli$
3. 创建2个key，导入key的私钥
liyuechun:cleos yuechunli$ ./cleos create key
Private key: 5Kg4i6WW6mfGXGjriU552KdAQ8tQyCU4mqtevVganWWbzQf1rD1
Public key: EOS5MSkE5DGgSurc7k3Sv9kWrev6E3GBBqasdiiC3yajPwrW7c4Uqliyuechun:cleos yuechunli$ ./cleos create key

imported private key for: EOS7wERhooVJwqYLuQn5v6UDZnL5KQpGJBDMQoktkxz4baNzicwLX
liyuechun:cleos yuechunli$ 4. 根据生成的公钥，创建帐号
$ liyuechun:cleos yuechunli$ ./cleos create account eosio eostoken EOS5MSkE5DGgSurc7k3Sv9kWrev6E3GBBqasdiiC3yajPwrW7c4Uq EOS7wERhooVJwqYLuQn5v6UDZnL5KQpGJBDMQoktkxz4baNzicwLX

# eosio <= eosio::newaccount {"creator":"eosio","name":"eostoken","owner":{"threshold":1,"keys":[{"key":"EOS5MSkE5DGgSurc7k3Sv9kW...
5. 查看账号信息
liyuechun:cleos yuechunli$ ./cleos get account eostoken
liyuechun:cleos yuechunli$ ./cleos get account eostoken
{"account_name": "eostoken","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS7wERhooVJwqYLuQn5v6UDZnL5KQpGJBDMQoktkxz4baNzicwLX","weight": 1}],"accounts": []}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5MSkE5DGgSurc7k3Sv9kWrev6E3GBBqasdiiC3yajPwrW7c4Uq","weight": 1}],"accounts": []}}]
}
liyuechun:cleos yuechunli$
6. 检测，并部署合约
$ ./cleos get code currency
$ ./cleos set contract currency ../../contracts/currency
$ ./cleos get code currency
liyuechun:cleos yuechunli$ ./cleos get code currency
code hash: 0000000000000000000000000000000000000000000000000000000000000000

liyuechun:cleos yuechunli$
7. 创建货币
$ ./cleos push action currency create '{"issuer":"currency","maximum_supply":"1000000.0000 CUR","can_freeze":"0","can_recall":"0","can_whitelist":"0"}' --permission currency@active
liyuechun:cleos yuechunli$ ./cleos push action currency create '{"issuer":"currency","maximum_supply":"1000000.0000 CUR","can_freeze":"0","can_recall":"0","can_whitelist":"0"}' --permission currency@active

# currency <= currency::create {"issuer":"currency","maximum_supply":"1000000.0000 CUR","can_freeze":0,"can_recall":0,"can_whitelis...
>> create
liyuechun:cleos yuechunli$
8. 发行货币
$ ./cleos push action currency issue '{"to":"currency","quantity":"1000.0000 CUR","memo":""}' --permission currency@active
liyuechun:cleos yuechunli$ ./cleos push action currency issue '{"to":"currency","quantity":"1000.0000 CUR","memo":""}' --permission currency@active
executed transaction: 7b8108d19aba6c8dcc601c321ef3c433cd2a3aedbd3ac1b217f06477792b40f7 248 bytes 106496 cycles
# currency <= currency::issue {"to":"currency","quantity":"1000.0000 CUR","memo":""}
>> issue
liyuechun:cleos yuechunli$
9. 查看帐号信息
$ ./cleos get table currency currency accounts
liyuechun:cleos yuechunli$ ./cleos get table currency currency accounts
{"rows": [{"balance": "1000.0000 CUR","frozen": 0,"whitelist": 1}],"more": false
}
liyuechun:cleos yuechunli$
10. 转账
$ ./cleos push action currency transfer '{"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}' --permission currency@active
$ ./cleos get table currency currency accounts
liyuechun:cleos yuechunli$ ./cleos push action currency transfer '{"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}' --permission currency@active
executed transaction: 4a24e5a9afd17abe61dcb3b3aff06a1c5ec94663f803d3d1801bd7a5046fea9e 272 bytes 109568 cycles
# currency <= currency::transfer {"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}
>> transfer
# eosio <= currency::transfer {"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}
liyuechun:cleos yuechunli$ ./cleos get table currency currency accounts
{"rows": [{"balance": "980.0000 CUR","frozen": 0,"whitelist": 1}],"more": false
}
