Solution is start it as replica set (command line or config parameter) and run rs.initiate() after that. Now you have one node replica set, what you can expand to three node, if you want.

Thanks. But according to the document, after rs.initiate(), we need to set configsvrMode to "sccc", then add other two members. Finally remove the sccc in the first member. However, we only use one member for development, so we confused how to handle it.

That documentation is stating how you convert your old config server without downtime. With only one config server it is of course impossible. And because that, you can keep your config server port number as it was, no need to change it.
