[galaxy-user] Can't seem to stop or restart the Galaxy in server

Hello Everyone. Ctrl+C or Ctrl+D doesn't stop the Galaxy server. In local machine, I need to close the terminal and restart the terminal again. However, in server I integrated several tools, now I need to restart the server to test it. I used ./run.sh --reload doesn't restart the server and I can't stop the server. How can I stop or restart Galaxy in the real working server? Thanks
