The issue is not missing Mysql DB. Its related to your home directory permission. As you can see you got permission denied message after login. Now I fixed your home directory permission - please be care in future while running
chmod command. Now login and type
myaql - it should work.
i am also facing same problem@laks, for me it showing unknown database
@Chetan , Please check now. I updated your records. If you still face issues. Let me know.
