安裝管理節點與其它節點安裝是一樣的
：

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) –
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=, 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
