Example MySQL config file for small systems.
This is for a system with little memory (, MASTER_PORT=,
MASTER_USER=, MASTER_PASSWORD= ;
where you replace , , by quoted strings and
by the master’s port number (3306 by default).
Example:
CHANGE MASTER TO MASTER_HOST=‚125.564.12.1‘, MASTER_PORT=3306,
MASTER_USER=‚joe‘, MASTER_PASSWORD=‚secret‘;
OR
2) Set the variables below. However, in case you choose this method, then
start replication for the first time (even unsuccessfully, for example
if you mistyped the password in master-password and the slave fails to
connect), the slave will create a master.info file, and any later
change in this file to the variables’ values below will be ignored and
overridden by the content of the master.info file, unless you shutdown
the slave server, delete master.info and restart the slaver server.
For that reason, you may want to leave the lines below untouched
(commented) and instead use CHANGE MASTER TO (see above)
required unique id between 2 and 2^32 - 1
(and different from the master)
defaults to 2 if master-host is set
but will not function as a slave if omitted
#server-id = 2
The replication master for this slave - required
#master-host =
The username the slave will use for authentication when connecting
to the master - required
#master-user =
The password the slave will authenticate with when connecting to
the master - required
#master-password =
The port the master is listening on.
optional - defaults to 3306
#master-port =
binary logging - not required for slaves, but recommended

Point the following paths to different dedicated disks

Uncomment the following if you are using BDB tables
#bdb_cache_size = 4M
#bdb_max_lock = 10000
Comment the following if you are using InnoDB tables

innodb_log_group_home_dir = „C:/xampp1/mysql/data“
#innodb_log_arch_dir = „C:/xampp1/mysql/data“
You can set …_buffer_pool_size up to 50 - 80 %
of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M
Set …_log_file_size to 25 % of buffer pool size
innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
