EOSIO 多签的合约账户部署合约

支持我们，请投票给 rex.m

为保证合约账户资金的安全以及合约的稳定，有时候管理员会将账户的权限设置为多签，此时部署合约需要先提交部署合约的提案由多签的管理账户同意后，才可以执行合约的部署。

账户准备

这里，我们创建了4个账户:

• hello: 多签的合约账户
• meetonetest1: 管理账户1
• meetonetest2: 管理账户2
• meetonetest3: 管理账户3

hello在刚创建时配置了一对owner和active密钥。在部署合约之前将hello账户的active权限设置为2/3的多签账户，即需要3个管理账户中的2个以上同意就可以授权hello的执行交易。

生成用于部署合约的交易

hello账户需要提交部署合约的事务的提案，以便在执行之前从管理账户处获得批准。提交部署合约事务的提案前首先得以JSON格式在本地生成并保存该笔事务： 生成并保存该笔事务的方法：

需要修改ref_block_num和ref_block_prefix的值为0，而expiration的时间要设置成你部署合约的期限之后，需要在你设置的时间之前完成合约的部署。修改后的deploy_hello_contract_trx.json前几行的内容如下：

{
  "expiration": "2019-03-06T10:00:00",
  "ref_block_num": 0,
  "ref_block_prefix": 0,
  "max_net_usage_words": 0,
  "max_cpu_usage_ms": 0,
  "delay_sec": 0,
  "context_free_actions": [],
  "actions": [{

同时需要创建一个管理者权限账户的manager_permission.json文件：

[
  {"actor": "meetonetest1", "permission": "active"},
  {"actor": "meetonetest2", "permission": "active"},
  {"actor": "meetonetest3", "permission": "active"}
]

提交部署合约事务的提案

只有多签的中的任意一个管理账户才可以提交hello部署合约事务的提案，同时提交部署合约提案的管理者需要暂时为提交的提案提供RAM，不过RAM会在提交的提案被执行后自动返回给该管理者。 这里将以meetonetest1来提交事务：

cleos multisig propose_trx deployhello manager_permission.json deploy_hello_contract_trx.json meetonetest1
executed transaction: 1f0a3557824ae1f1610c0b70a2ab2c7828b920407c0e4241ef7c023c6f11cebc  11896 bytes  4046 us
#    eosio.msig <= eosio.msig::propose          {"proposer":"meetonetest1","proposal_name":"deployhello","requested":[{"actor":"meetonetest1","permi...
warning: transaction executed locally, but may not be confirmed by the network yet         ] 

批准部署合约事务的提案

当管理者都同意该笔事务的提案时：

cleos multisig approve meetonetest1 deployhello '{"actor":"meetonetest2","permission":"active"}' -p meetonetest2@active
executed transaction: 8df616f038970b017162ea537ffa3451fde4b7401604318d1f52e3e4b3e75308  128 bytes  252 us
#    eosio.msig <= eosio.msig::approve          {"proposer":"meetonetest1","proposal_name":"deployhello","level":{"actor":"meetonetest2","permission...
warning: transaction executed locally, but may not be confirmed by the network yet       

执行提案部署合约

当需要的批准数满足要求时（3个管理者中，至少有2个管理者批准），任何一个管理者都可以使用eosio.misg::execaction执行该事务部署合约：

cleos multisig exec meetonetest1 deployhello meetonetest1                                                
executed transaction: 3e09349fbe9278f9c5c38543d041bdfa82b5821e269ca8c20433f8565dc0489c  160 bytes  2144 us
#    eosio.msig <= eosio.msig::exec             {"proposer":"meetonetest1","proposal_name":"deployhello","executer":"meetonetest1"}
warning: transaction executed locally, but may not be confirmed by the network yet         ] 

在本地测试时候此时可能会出现错误的提示：

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.
Error Details:
transaction declares authority '{"actor":"hello","permission":"active"}', but does not have signatures for it under a provided delay of 0 ms, provided permissions [{"actor":"eosio.msig","permission":"eosio.code"}], provided keys [], and a delay max limit of 3888000000 ms
pending console output: 

这是因为本地的eosio.misg账户没有非特权账户。 没有设置之前：

cleos get account eosio.msig                                                                                           
created: 2019-03-01T06:14:52.000
permissions: 

设置之后：

cleos push action eosio setpriv '["eosio.msig", 1]' -p eosio
cleos get account eosio.msig                                
created: 2019-03-01T06:14:52.000
privileged: true
permissions:

以上便是给多签的账户部署合约的流程。
