YOu could look into "support-files" dir in you mysql directory where you'd find several pre-definied ini files.
Here is sample of my-medium.ini file:
Example mysql config file for medium systems.
#
This is for a system with little memory (32M - 64M) where MySQL plays
a important part and systems up to 128M very MySQL is used together with
other programs (like a web server)
#
You can copy this file to
/etc/mf.cnf to set global options,
mysql-data-dir/my.cnf to set server-specific options (in this
installation this directory is /home/mysql) 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
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock
Here follows entries for some specific programs
The MySQL server
[mysqld]
port = 3306
socket = /tmp/mysql.sock
skip-locking
set-variable = key_buffer=16M
set-variable = max_allowed_packet=1M
set-variable = table_cache=64
set-variable = sort_buffer=512K
set-variable = net_buffer_length=8K
set-variable = myisam_sort_buffer_size=8M
log-bin
server-id = 1
Uncomment the following if you are using BDB tables
#set-variable = bdb_cache_size=4M
#set-variable = bdb_max_lock=10000
Point the following paths to different dedicated disks
#tmpdir = /tmp/
#log-update = /path-to-dedicated-directory/hostname
[mysqldump]
quick
set-variable = max_allowed_packet=16M
