mysqlでネットワーク接続できない話

ERROR 2013: Lost connection to MySQL server during query

Number of processes running now: 1
mysqld process hanging, pid 14587 - killed
080620 13:06:23  mysqld restarted
Cannot initialize InnoDB as 'innodb_data_file_path' is not set.
If you do not want to use transactional InnoDB tables, add a line
skip-innodb
to the [mysqld] section of init parameters in your my.cnf
or my.ini. If you want to use InnoDB tables, add to the [mysqld]
section, for example,
innodb_data_file_path = ibdata1:10M:autoextend
But to get good performance you should adjust for your hardware
the InnoDB startup options listed in section 2 at
http://www.innodb.com/ibman.html
/usr/libexec/mysqld: ready for connections

InnoDBがどうのこうのというあたりはmy.cnfにskip-innodbを追記すれば直る
