This is strange behavior because as soon as I start mysqld with a clean error log, I get the following messages:
110720 21:38:47 [Note] /usr/libexec/mysqld: ready for connections. Version: '5.5.14-log' socket: '/var/lib/mysql/mysql.sock' port: 2500 MySQL Community Server (GPL) by Remi
110720 21:38:48 [Warning] Access denied for user 'UNKNOWN_MYSQL_USER'@'localhost' (using password: NO)
The strange things is, AFAIK there are no clients trying to connect to mysql. I shutdown a mysql CLI monitor I had running, and did the restart again.
So I'm just wondering why I get this message, when AFAIK there is nothing that should be trying to connect to mysql - unless it's a server daemon running somewhere?
Has anyone else come across this funny error message?
There must be some service that does uses MySQL but does not have user set. Website like CMS? Try getting more logs to see what app/script uses it.
