I don't understand the sentence about the data directory path mention.  The my.cnf file is at /etc/my.cnf . It doesn't have any data directory path mention, but neither does the my.cnf file on a laptop, which works. So there seems to be nothing wrong with the location or content of the my.cnf file.
