Answer 1

I found the problem, The mysql library update stucks. That is why mysql server updating process not be completing.

When i check command "ps aux | grep mysql", i got process list of mysql update stuck processing as in given below image click here to show image

So, when i killed those both processes(pid=6728 and 7041), I am able to connect mysql server easily.
