nginx file is consuming hard drive

Why does the file /usr/local/nginx/on take up so much hard drive spa开发者_运维问答ce on my web server? What can i do to reduce it?

Probably, in your nginx.conf situated something like this: error_log on;

You might have "access_log on" defined in your nginx config file. Remove it from your config file if you dont want that file to be created.
