1.运行测试程序run_simulator
编译btcpool源码之后，运行其测试程序
cd /work/btcpool/build/run_simulator
./simulator -c simulator.cfg -l log_simulator这个程序没有hang住，直接“完”了，我拿不准这个程序是否运行出错了还是怎么样。
请教各位大侠，是否知道btcpool的测试程序（run_simulator）如何正确运行，谢谢！
2.查看问题
我查看log_simulator下面的日志发现日志最下面一行如下：
E0403 14:34:04.956310 698 StratumClient.cc:256] event error: Connection refused判断是sserver没有启动，我单独用命令去启动sserver，如下：

如 sserver 日志所示
参考 sserver.cfg 的注释，你需要自己搭建一个网站服务器（xx.yy），并提供一个网站接口（/get_user_id_list），然后把网址写入 sserver.cfg 文件的 list_id_api_url 项，如下
你可以在本机搭建一个 apache 或者 nginx 服务器，然后按照
https://github.com/btccom/btc...
上的说明操作便可。
