mysql 无法启动 unkown command

I have a big problem.

i try to start mysql in ubuntu, butI have this error:

130323  0:13:55 [Note] Plugin 'FEDERATED' is disabled.

This has no sense, because I dont use that in the my.cnf:

    #
# The MySQL database server configuration file.
#
# 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.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
