# MariaDB The program looks for the operating system platform on which it is running 1 Series of configuration files ,
# You can copy this template configuration file to the appropriate location ( And rename ),
# To see which profiles are read , perform :

# Configuration options from server Replication Slave ( You need to master Partially comment out , To use this part )
#
# To configure the server as a slave (replication slave),
# There are two options available :
#
# 1) through CHANGE MASTER TO The command ( It is described in detail in the user's manual ) -
# Syntax is as follows :
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# You can take <host>, <user>, <password> Replace with a string enclosed in single quotes ,
# will <port> Replace with master The port number ( The default is 3306).
#
# 1 An example is shown below :
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# or :
#
# 2) Set the following parameters . However, , 1 Once you choose this way ,
# When master slave replication is first started ( Even if starting replication fails , Such as the wrong master-password password ,
# Lead to slave Bad connection ), slave Will be created 1 called master.info The file ,
# If you modify this configuration file later (xxx.cnf) These parameters are below , Will be ignored ,
# And continue to use master.info Contents of the file ,
# Unless close slave The server , And then delete the file master.info And restart it slaver server.
# For this reason , You should not systematically modify the following parameters ( with <> Comment section ),
# It USES CHANGE MASTER TO ( The above scheme 1)
#
#
# The requirement is for the entire master-slave replication cluster 2 to 2^32 - 1 Only between 1ID,
# Or fail , Or a lot of error log information .
# If it's set master-host, The default value is 2
# But if I omit it , It doesn't become slave
