Title: run always use DefaultOption

when run is called without param, the `defaultOptions` is always used.

this PR change it,
when run is called 1st time:
we use the option which is merged from `default` and `options from param`.
And save it.
when run is called again,
The `option uesd last time` is merged with `the new param options`( if it is given ).
Then we use this new options.

in this way, the server.run can be called once and run again and again without options any more.
