mysql throw an error message like below:

I tried to create a directory with mysql user in "/var/lib/mysql" as well as outside the "/var/lib/mysql" but no success, still coming error messages.
The MySQL data directory contains as follows:
root@intranet:/var/lib/mysql# ls -l

How to repeat:
Basic installation of the Ubuntu server. There aren't any extra package, just install the MySQL Server.
