EOS发起交易时，提示ram，net或cpu资源不足问题分析与解决（Error 3080001: account using more than allotted RAM usage）

 2018-07-05　  Surou　  阅读 　  EOS-新手教程　  0 评论

一般创建账号，或者三方购买的账号都是最低的资源创建的 （cleos system newaccount 消耗最少的EOS资源）
基本账号下CPU和NET都是零，RAM 3kb以下，因为RAM收费逻辑（EOS零手续费免费?你不知道的EOS收费细节）

  • 只要action中执行了持久化存储相关的逻辑就需要收取ram使用费，比如系统合约的newaccount ,updateauth, setcode, setabi, schedule_deferred_transaction, eosio.token的transfer

所以在账号资源不足的情况下，转账操作会提示以下错误

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos push action eosio.token transfer '["eosio", "bcskillsurou","100.0000 EOS","vote"]' -p eosio

Error 3080001: account using more than allotted RAM usage

提示RAM不足已支持转账
如果自己给自己直接购买RAM的话

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos system buyram bcskillsurou bcskillsurou "0.1000 EOS"
3536793ms thread-0   main.cpp:429                  create_action        ] result: {"binargs":"a0e9d5384607313aa0e9d5384607313ae80300000000000004454f5300000000"} arg: {"code":"eosio","action":"buyram","args":{"payer":"bcskillsurou","receiver":"bcskillsurou","quant":"0.1000 EOS"}} 
Error 3080002: transaction exceeded the current network usage limit imposed on the transaction

提示NET不足
如果自己给自己抵押换取NET和CPU时

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos system delegatebw bcskillsurou bcskillsurou '0.1000 EOS' '0.1000 EOS' -p bcskillsurou

48403ms thread-0   main.cpp:429                  create_action        ] result: {"binargs":"a0e9d5384607313aa0e9d5384607313ae80300000000000004454f5300000000e80300000000000004454f530000000000"} arg: {"code":"eosio","action":"delegatebw","args":{"from":"bcskillsurou","receiver":"bcskillsurou","stake_net_quantity":"0.1000 EOS","stake_cpu_quantity":"0.1000 EOS","transfer":false}} 
Error 3080001: account using more than allotted RAM usage

又提示RAM不足...先有鸡还是先有蛋，死循环。所以只能让其他RAM资源充足的账号例如 eosio 帮此账号bcskillsurou购买

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos system buyram eosio bcskillsurou "0.1000 EOS"
177473ms thread-0   main.cpp:429                  create_action        ] result: {"binargs":"0000000000ea3055a0e9d5384607313ae80300000000000004454f5300000000"} arg: {"code":"eosio","action":"buyram","args":{"payer":"eosio","receiver":"bcskillsurou","quant":"0.1000 EOS"}}

warning: transaction executed locally, but may not be confirmed by the network yet

当bcskillsurouRAM足够后，就可以自己或者其他账号抵押购买CPU和NET了

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos system delegatebw bcskillsurou bcskillsurou '0.1000 EOS' '0.1000 EOS' -p bcskillsurou

此时再次转账的话

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos get currency balance eosio.token bcskillsurou
99.8000 EOS
surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos push action eosio.token transfer '["bcskillsurou", "eosio","1.0000 EOS","vote"]' -p bcskillsurou

surou@surou-C-H110M-K-Pro:~/.local/share/eosio/nodeos/config$ cleos get currency balance eosio.token bcskillsurou

就一切OK了

最少需要RAM 3kb,具体等于多少EOS需要根据当前RAM的价格来定

EOS enable mongodb

 2018-07-05　  Surou　  阅读 　  EOS-新手问答　  0 评论 
git clone -b release/1.1 https://github.com/EOSIO/eos.git
cd eos
git fetch –all –tags –prune
git merge -m “merge” –commit origin/gh#3030-enable-mongodb
git submodule update –init –recursive
./eosio_build.sh
cd build
make install

修改config.ini配置文件，添加如下两行：

plugin = eosio::mongo_db_plugin
mongodb-uri = mongodb://localhost:27017/eosmain

其中，eosmain是要写入的MongoDB数据库名。
好了，万事俱备，开始启动
进入~/opt/mongodb/bin目录，启动MongoDB服务。

cd ~/opt/mongodb/bin
./mongod

这时MongoDB服务会默认监听27017端口，如下图所示。

新开一个小窗，重启nodeos，需要加上–replay-blockchain，以使历史交易数据同步到MongoDB。
如果没有意外的话，此时MongoDB应该开始写入相关记录了。
执行mongo程序进入MongoDB控制台，查询相应数据库和记录，如下图。

boost::interprocess::bad_alloc

 2018-07-05　  Surou　  阅读 　  EOS-新手问答　  0 评论

由于解决 cleos get transaction 返回空的信息
此问题，导致运行 nodeos 提示以下错误

terminate called after throwing an instance of 'boost::interprocess::bad_alloc'
  what():  boost::interprocess::bad_alloc

解决方案：修改 config.ini 中 chain-state-db-size-mb调大些，默认1024，一般改为2048即可，当然服务器内存较大可以再多分些。
