# * Logging and Replication
#

# Note: The configured log file or its directory need to be created
# and be writable by the mysql user, e.g.:
# $ sudo mkdir -m 2750 /var/log/mysql
# $ sudo chown mysql /var/log/mysql

# Both location gets rotated by the cronjob.
# Be aware that this log type is a performance killer.
# Recommend only changing this at runtime for short testing periods if needed!

#
# Error log - should be very few entries.

# * InnoDB
#

# Read the manual for more InnoDB related options. There are many!
# Most important is to give InnoDB 80 % of the system RAM for buffer use:
