5# other programs (such as a web server)

7# In this file, you can use all long options that a program supports.
8# If you want to know which options a program supports, run the program
9# with the "--help" option.

79# Replication Slave (comment out master section to use this)
80#
81# To configure this host as a replication slave, you can choose between
82# two methods :
83#
84# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
85# the syntax is:
86#
87# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
88# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
89#
90# where you replace <host>, <user>, <password> by quoted strings and
91# <port> by the master's port number (3306 by default).
92#
93# Example:
94#
95# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
96# MASTER_USER='joe', MASTER_PASSWORD='secret';
97#
98# OR
99#
100# 2) Set the variables below. However, in case you choose this method, then
101# start replication for the first time (even unsuccessfully, for example
102# if you mistyped the password in master-password and the slave fails to
103# connect), the slave will create a master.info file, and any later
104# change in this file to the variables' values below will be ignored and
105# overridden by the content of the master.info file, unless you shutdown
106# the slave server, delete master.info and restart the slaver server.
107# For that reason, you may want to leave the lines below untouched
108# (commented) and instead use CHANGE MASTER TO (see above)
109#
110# required unique id between 2 and 2^32 - 1
111# (and different from the master)
112# defaults to 2 if master-host is set
113# but will not function as a slave if omitted
114#server-id = 2
115#
116# The replication master for this slave - required
117#master-host = <hostname>
118#
119# The username the slave will use for authentication when connecting
120# to the master - required
121#master-user = <username>
122#
123# The password the slave will authenticate with when connecting to
124# the master - required
125#master-password = <password>
126#
127# The port the master is listening on.
128# optional - defaults to 3306
129#master-port = <port>
