Linux disk space is abnormally full, how to check?

In the process of server operation and maintenance, we often encounter such a situation and receive a server disk space alarm: log in to the server, use df-Hl to check that the alarm information is consistent, and then we need to find the directory or file that causes the disk space to be full.

A relatively more efficient method is to use du - The d parameter, or –max-depth, sets the directory depth of the query.

I purchased a certificate provided by a web server. I'm not using a self-signed certificate.

From what I understand it is highly recommended for applications to use ssl
