Contoh Konfigurasi File /etc/my.cnf untuk MySQL

Di bawah ini adalah contoh konfigurasi file /etc/my.cnf yang digunakan sebagai file setting untuk MySQL pada server.

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Settings user and group are ignored when systemd is used (fedora >= 15).
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mysqld according to the
# instructions in http://fedoraproject.org/wiki/Systemd
user=mysql

# Semisynchronous Replication
# http://dev.mysql.com/doc/refman/5.5/en/replication-semisync.html
# uncomment next line on MASTER
;plugin-load=rpl_semi_sync_master=semisync_master.so
# uncomment next line on SLAVE
;plugin-load=rpl_semi_sync_slave=semisync_slave.so

# Others options for Semisynchronous Replication
;rpl_semi_sync_master_enabled=1
;rpl_semi_sync_master_timeout=10
;rpl_semi_sync_slave_enabled=1

# http://dev.mysql.com/doc/refman/5.5/en/performance-schema.html
;performance_schema

# Add by me to calculate and log long MySQL Server
long_query_time = 1
log_slow_queries = /var/log/mysql/mysql-slow.log

expire_logs_days = 3

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

Mungkin konfigurasi ini memang standard sekali, meskipun begitu sudah cukup digunakan sebagai konfigurasi dari beberapa website.
