Problem in Installing MySQL/MariaDB

I followed all the instructions but I’m getting this error:

Hi @Aditya-Pande ,
There is minor mistake.
You have to perform all the steps on app01 server. but you are doing in the host01 server.

thor@host01 ~$

Format to remember: - UserName@ServerName~$

If ServerName is not set then you will see the IP address of that server.

Please check that SSH line in the attached screenshot.
