Sample MySQL Configuration File and Parameter Details

Here is a copy of a sample MySQL configuration file and details on few main parameters:

# Example mysql config file for small systems.
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld deamon
# doesn't use much resources.
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/mysql/var) or
# ~/.my.cnf to set user-specific options.
# One can in this file use all long options that the program supports.
# If you want to know which options a program support, run the program
# with --help option.

# The following options will be passed to all MySQL clients
#password	= your_password
port		= 3306
socket		= /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
port		= 3306
socket		= /tmp/mysql.sock
set-variable	= key_buffer=128K
set-variable	= max_allowed_packet=1M
set-variable	= thread_stack=64K
set-variable	= table_cache=4
set-variable	= sort_buffer=64K
set-variable	= net_buffer_length=2K
server-id	= 1

# Uncomment the following if you are NOT using BDB tables

# Uncomment the following if you are using Innobase tables
#innodb_data_file_path = ibdata1:100M
#innodb_data_home_dir = /usr/local/mysql/var/
#innodb_log_group_home_dir = /usr/local/mysql/var/
#innodb_log_arch_dir = /usr/local/mysql/var/
#set-variable = innodb_mirrored_log_groups=1
#set-variable = innodb_log_files_in_group=3
#set-variable = innodb_log_file_size=5M
#set-variable = innodb_log_buffer_size=8M
#set-variable = innodb_buffer_pool_size=16M
#set-variable = innodb_additional_mem_pool_size=2M
#set-variable = innodb_file_io_threads=4
#set-variable = innodb_lock_wait_timeout=50

set-variable	= max_allowed_packet=16M

# Remove the next comment character if you are not familiar with SQL

set-variable	= key_buffer=8M
