MySQL Configuration file

Line 
1# Example MySQL config file for medium systems.
2#
3# This is for a system with little memory (32M - 64M) where MySQL plays
4# an important part, or systems up to 128M where MySQL is used together with
5# other programs (such as a web server)
6#
7# You can copy this file to
8# /etc/my.cnf to set global options,
9# mysql-data-dir/my.cnf to set server-specific options (in this
10# installation this directory is /usr/local/mysql/data) or
11# ~/.my.cnf to set user-specific options.
12#
13# In this file, you can use all long options that a program supports.
14# If you want to know which options a program supports, run the program
15# with the "--help" option.

17# The following options will be passed to all MySQL clients

69# Replication Slave (comment out master section to use this)
70#
71# To configure this host as a replication slave, you can choose between
72# two methods :
73#
74# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
75#    the syntax is:
76#
77#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
78#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
79#
80#    where you replace <host>, <user>, <password> by quoted strings and
81#    <port> by the master's port number (3306 by default).
82#
83#    Example:
84#
85#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
86#    MASTER_USER='joe', MASTER_PASSWORD='secret';
87#
88# OR
89#
90# 2) Set the variables below. However, in case you choose this method, then
91#    start replication for the first time (even unsuccessfully, for example
92#    if you mistyped the password in master-password and the slave fails to
93#    connect), the slave will create a master.info file, and any later
94#    change in this file to the variables' values below will be ignored and
95#    overridden by the content of the master.info file, unless you shutdown
96#    the slave server, delete master.info and restart the slaver server.
97#    For that reason, you may want to leave the lines below untouched
98#    (commented) and instead use CHANGE MASTER TO (see above)
99#
100# required unique id between 2 and 2^32 - 1
101# (and different from the master)
102# defaults to 2 if master-host is set
103# but will not function as a slave if omitted
104#server-id       = 2
105#
106# The replication master for this slave - required
107#master-host     =   <hostname>
108#
109# The username the slave will use for authentication when connecting
110# to the master - required
111#master-user     =   <username>
112#
113# The password the slave will authenticate with when connecting to
114# the master - required
115#master-password =   <password>
116#
117# The port the master is listening on.
118# optional - defaults to 3306
