I need run geth on server without console. How to do this? just not add argument console?
And can I attach to geth running without console, when I want to stop geth, or open console.
If you append an '&' at the end of your geth <args> & command, it will run the command as a separate process in the background. Then you should be able to connect to it with geth attach from a separate console to stop or modify it.
