MySql互为主从配置文件及配置方法

# Example MySQL config file for medium systems.

#

# This is for a system with little memory (32M - 64M) where MySQL plays

# an important part, or systems up to 128M where MySQL is used together with

# other programs (such as a web server)

#

# You can copy this file to

# /etc/my.cnf to set global options,

# mysql-data-dir/my.cnf to set server-specific options (in this

# installation this directory is C:\mysql\data) or

# ~/.my.cnf to set user-specific options.

#

# In this file, you can use all long options that a program supports.

# If you want to know which options a program supports, run the program

# with the "--help" option.





# The following options will be passed to all MySQL clients

[client]

#password = your_password

port = 3306

socket = /tmp/mysql.sock

# Replication Slave (comment out master section to use this)





# New for MySQL 5.6 if no slave









#

# 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)

#

# 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     =   <hostname>

#

# The username the slave will use for authentication when connecting

# to the master - required

#master-user     =   <username>

#

# The password the slave will authenticate with when connecting to

# the master - required

#master-password =   <password>

#

# The port the master is listening on.

# optional - defaults to 3306

#master-port     =  <port>

#

# binary logging - not required for slaves, but recommended

上面是我的配置文件

配置方法如下：

server-id = 1  #每台机器不一样就行了

log-bin=D:/wamp/bin/mysql/mysql5.6.17/mysqlback #通过日志同步，所以这个目录要建一下

binlog-do-db = backup_db                                         #同步数据库 多个就写多行

replicate-do-db = backup_db                                     #同步数据库 多个就写多行

skip-slave-start=0                                                      #启动后自动启动slave模式

在mater上添加用户（如果互为主从都需要设置）

grant file,select,replication slave on *.* to 'cw'@'192.168.1.%' identified by '111111';

show master status;









在slave上执行配置（如果互为主从都需要设置）

stop slave;

CHANGE MASTER TO MASTER_HOST='192.168.1.150', MASTER_PORT=3306,MASTER_USER='cw', MASTER_PASSWORD='111111';

start slave;
