Now there is a 404 error, proving thenginx还是能启动起来的，你可以确认一下/home/wfp/chatyou.net/website目录下有没有index.htmlfile.

There is a permission problem when you do this. nginx is the www-data user, and the root directory of your website is owned by wfp. You also need to change a permission setting,
I once had a problem like this and I did this and thought it would be safer
