everything is in order! 

 The data nodes don't have individual files for each table and so you won't see the table names there. What you're seeing with the MySQL Server directories is not the files containing the contents of the tables but a copy of the data dictionary/schema definitions for those tables (e.g. if you add more rows to these tables then the files you see with the data nodes should increase in size but the ones with the MySQL Servers should not).

Look at the .frm files. They are owned by root root.

They are supposed to be owned by mysql mysql

My guess is that you copied the data rather than use MySQL techniques to import.

Perhaps you should change the ownership of the entire data folder.

Please run the following commands:

cd /var/www/xampp/mysql/data
chown -R mysql:mysql *

Then restart mysql.

As for the error messages, the InnoDB System Tablespace (ibdata1) and the Redo Log Files (ib_logfile0,ib_logfile1) are being created.

From the above messages, my guess is that you did this something like this

• You had shutdown mysql
• You copied /var/lib/mysql to /var/www/xampp/mysql/data
• You started mysql
• mysqld did not see InnoDB Infrastructure files, so they were created

If you have an all-MyISAM database (every table uses the InnoDB storage engine) you can easily get away with copying data folders. You would still have to change file ownership to mysql mysql. If there are any InnoDB tables, you must copy the entire data folder, not just a database within the data folder.

CAVEAT

Please note that running SHOW TABLES; simply walks across the current database telling you table names by looking at the .frm files without checking ownership or table validity. Once you actually perform some SQL again the table that all metadata checks against the table are done.
