[zhanb]

hi,when i set a ready being used like this :
settings->set_port(8080);
the progream would coredump,
the error message :
terminate called after throwing an instance of 'std::system_error'
what(): bind: Permission denied
Aborted (core dumped)

the core message:

should i use the try catch before service start? But i can not find it in the exmple

You don't have permission to bind to that port 8080. Use a port your user has privileges for.
