Submitted:	23 Jul 2013 0:56	Modified:	29 Jul 2013 18:35
Reporter:	James Niland	Email Updates:
Status:	Not a Bug	Impact on me:	None
Category:	MySQL Server: Errors	Severity:	S2 (Serious)
Version:	5.5	OS:	Linux (ubuntu 12.04 LTS)
Assigned to:		CPU Architecture:	Any

Description:
Can't connect to database without getting error 1524 Plugin 'none' is not loaded. Where dose this come from? I was working fine before upgraded from Ubuntu 10.04 LTS to 12.04 LTS. I have purged and reinstalled both mysql-server and mysql workbench-gpl and still get the error

How to repeat:
service start mysql-sever

Please check if in some way is related: http://bugs.mysql.com/bug.php?id=60432 . Thanks.

No it is not. I have tried to start with --skip-grant-tables and still get the error

Have you checked if in the OS upgrade the original my.cnf was rewritten? .

here is it' content

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.

# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

Thank you for the feedback.

But we need MySQL Server error log. It is specified as /var/log/mysql/error.log in your configuration file.

Sorry I am a novice at this, but every one learns some how

Thank you for the feedback. Look your err file sounds an OS upgrade issue than a MySQL bug, please check for multiples servers instances alos for multiples my.cnf configuration files. Thanks.

I only had one my.cnf file and once again purged Mysql and reinstalled and have come back to the same error SQLSTATE[HY000] [1524] Plugin 'none' is not loaded. What is plugin none and where is it loaded from? I ran netstat -tap | grep mysql and only one is shown. what do I do next?

Please check your err log file about InnoDB messages you have installed 5.5 server over a 5.1.69 install.
