Hello, I am confused about repliction setup. Reading a config file,
and the docs, leads me to believe this is an either code choice, pick
#1 or #2. If that is the case, why would I want to use #1 over #2?
My confusion comes from several online references where there is a
combination of #1 and #2 going on:
# 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=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> 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)
