My VPS is using CentOS system, after a period of time found that VPS hard disk occupation is very large, but their own website data is not much, so what is occupying my VPS hard disk space? We can analyze this by using the du -sh command.

After logging in to SSH of the VPS, enter the following command: du -sh /*

You can list the size of all your VPS folders. / is used to control which directory is to be analyzed, for example, du -sh /usr/

Use this command to analyze the size of the folders in the usr directory, and finally locate the large files and delete them.
