Check the scope and prerequisites first
Confirm the software version, operating system, and permission requirements corresponding to the document. The interface or parameters in the old documentation may have changed, and the current official instructions should be checked first.
Distinguish examples from your actual settings
The example domain name, username and path need to be replaced with the actual environment. Understand what the command will read or modify before executing it, paying special attention to the operations of overwriting configuration and deleting data.
Check each result as you proceed
After each stage is completed, check whether the results described in the document appear. Saving necessary operation records and recoverable original configurations is more helpful for learning than simply copying commands.
