Re: mysql connection error
It says lost error during query.. but I'd be suspect if it even succesfully connected/authenticated.. I'd do a quick check first to ensure your mysql server is listening on the 192.xxx interface.. if it's unix, netstat -atn On Thu, 17 Jul 2003, zafar rizvi wrote: > hi > I am running one centralized mysql server, its runnig fine and conneded with > localhost and his own ip very fine. > But when i want to connect him from remote system or other lan system > it give me errror like that. > > [EMAIL PROTECTED] root]# mysql -h 192.168.0.63 mysql > ERROR 2013: Lost connection to MySQL server during query > > Anybody has idea what's wrong and where is ? > I get no answer from searching on google with that error. > > Waiting for reply > ThAnks > > ZaFAr > > > -- > MySQL General Mailing List > For list archives: http://lists.mysql.com/mysql > To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED] > -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: MySQL Connection error
You might want to look in the crontab to see if rotatelogs is rotating
the logs for mysql. If it is, the mysql database is bounced. The easy
thing to do is just to check the connection and make sure it is open
before using it.
i.e.
if (conn.isClosed()) {
conn=db.getConnection()
}
