参考这篇 Learn about Keys, Wallets and Accounts with cleos

创建钱包

alias cleos

alias cleos='docker exec -it keosd /opt/eosio/bin/cleos --url http://172.18.0.2:8888 --wallet-url http://127.0.0.1:9876'

cleos wallet create -n alex-wallet --to-console

Creating wallet: alex-wallet
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.

创建密钥对

➜  ~ cleos create key --to-console
Private key: 5JywyoJd2Rcp7iK25Eo8tfW948Z2MALLZVHrs8y3eqpLuQN6c61
Public key: EOS5a6853arFA45voyGqBdzB4fmcLh1GXuknN7tpdkLgZrVbc8TYC
➜  ~
➜  ~ cleos create key --to-console
Private key: 5K2pVCChktdFBHLsXPd8saxWsLp4acybi2WfPjv8NErXEG8rtNE
Public key: EOS7z641AZEiThbBMGUDx1uH3457npKyW5s7VWAXNf48YW6eaw7sb
➜  ~

将密钥导入wallet：

cleos wallet import -n alex-wallet --private-key
private key: imported private key for: EOS5a6853arFA45voyGqBdzB4fmcLh1GXuknN7tpdkLgZrVbc8TYC

cleos wallet import -n alex-wallet --private-key
private key: imported private key for: EOS7z641AZEiThbBMGUDx1uH3457npKyW5s7VWAXNf48YW6eaw7sb

创建账户

先查看下钱包里的公钥

➜  ~ cleos wallet keys
[
  "EOS5a6853arFA45voyGqBdzB4fmcLh1GXuknN7tpdkLgZrVbc8TYC",
  "EOS7z641AZEiThbBMGUDx1uH3457npKyW5s7VWAXNf48YW6eaw7sb"
]

创建账户：

cleos create account eosio alex EOS5a6853arFA45voyGqBdzB4fmcLh1GXuknN7tpdkLgZrVbc8TYC EOS7z641AZEiThbBMGUDx1uH3457npKyW5s7VWAXNf48YW6eaw7sb

报错：
Error 3090003: Provided keys, permissions, and delays do not satisfy declared authorizations
Ensure that you have the related private keys inside your wallet and your wallet is unlocked.

解决：

cleos wallet import -n alex-wallet --private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

private key: imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

重新创建账户：

cleos create account eosio alex EOS5a6853arFA45voyGqBdzB4fmcLh1GXuknN7tpdkLgZrVbc8TYC EOS7z641AZEiThbBMGUDx1uH3457npKyW5s7VWAXNf48YW6eaw7sb

通过公钥查询账户信息:

cleos get accounts EOS5a6853arFA45voyGqBdzB4fmcLh1GXuknN7tpdkLgZrVbc8TYC

{
  "account_names": [
    "alex"
  ]
}

根据账户名查询账户：

cleos get account alex

创建智能合约

eosiocpp -n hello
eosiocpp -g /hello/hello.abi /hello/hello.cpp 
eosiocpp -o /hello/hello.wast /hello/hello.cpp 

部署智能合约：

cleos set contract alex /hello hello.wast hello.abi -p alex@active

Reading WASM from /hello/hello.wast...
WARNING: /hello/hello.wast doesn't look like a binary WASM file. Is it something else, like WAST? Trying anyways...
Publishing contract...
Error 3070003: Serialization Error Processing WASM

报错， 将wasm换成wast
