# The settings provided below are a starting point for a 2GB - 4GB RAM server with 2-4 CPU cores.
# If you have less or more resources available you should adjust accordingly to save CPU,
# RAM and disk I/O usage.
# The settings marked with a specific comment or the word "UPD" after the value
# should be adjusted for your system by using database diagnostics tools like:
# https://github.com/major/MySQLTuner-perl
# or
# https://launchpad.net/mysql-tuning-primer (supports MySQL up to v5.6)
#
#
# Note that if there is NO comment after a setting value, then 99,9% of the times you won't need to adjust it.
#
#
# THINGS TO DO AFTER YOU UPDATE MY.CNF - TROUBLESHOOTING
# If any terminal commands are mentioned, make sure you execute them as "root" user.
# If MySQL cannot start or restart, then perform the following actions.
#
# 1. If the server had the stock database configuration and you added or updated any
# "innodb_log_*" settings (as suggested below), then execute these commands ONLY
# the first time you apply this configuration:
#
# $ rm -rvf /var/lib/mysql/ib_logfile*
# $ chown -R mysql:mysql /var/lib/mysql
# $ service mysql restart
#
# or use the shorthand command:
# $ rm -rvf /var/lib/mysql/ib_logfile*; chown -R mysql:mysql /var/lib/mysql; service mysql restart
#
# 2. If the setting "bind-address" is not commented out, then make sure the file /etc/hosts is
# properly configured. A good example of a "clean" /etc/hosts file is something like this:
#
# 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
# ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# 1.2.3.4 hostname.domain.tld hostname # Replace accordingly!
#
# Finally restart the database service:
#
# $ service mysql restart
#
# 3. If the database service cannot restart even after the first 2 steps, make sure the database data folder
# (common for either MySQL or MariaDB) "/var/lib/mysql" is owned by the "mysql" user AND group.
# Additionally, the folder itself can have 0751 or 0755 file permissions. To fix it, simply do this:
# $ chown -R mysql:mysql /var/lib/mysql
# $ chmod 0755 /var/lib/mysql
# You should have received a copy of the GNU General Public License
# along with this program; if not, write to the Free Software

#
# Finally restart the database service:
# The MySQL Server configuration file.
#
# $ service mysql restart
