用minerd連接btcpool的測(cè)試程序simulator時(shí)報(bào)錯(cuò)：JSON-RPC call failed.

本地ubuntu16.04編譯btcpool源碼，完成之后，運(yùn)行其測(cè)試程序simulator時(shí)出錯(cuò)

1.先運(yùn)行sserver程序

cd /work/btcpool/build/run_sserver
./sserver -c sserver.cfg -l log_sserver/

2.運(yùn)行simulator

cd /work/btcpool/build/run_simulator
./simulator -c simulator.cfg -l log_simulator/

3.模擬礦機(jī)連接, 出錯(cuò)：

minerd -o stratum+tcp://127.0.0.1:3333 -O aaa:1

   "Illegal params",
   null
]
[2018-04-04 15:17:07] ...retry after 30 seconds

這里的json-RPC出錯(cuò)，是不是因?yàn)檫€有其他依賴(lài)的服務(wù)沒(méi)有啟動(dòng)？是什么服務(wù)？
