A, mysql master-slave configuration:
1, the main mysql
192.168.146.13 ：
Create a database to be synchronized:
mysql>create database HA;
mysql>use HA;
mysql> create table test(id int,name char(20));
mysql> insert into test values(‘001’,’zhangsan’);
/etc/init.d/mysqld stop
vim /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
Add the following four lines:
log-bin = mysql-bin-master # enable binary logging
server-id = 1 # native database ID Flag
binlog-do-db = HA # can be replicated from the server database. Binary need to synchronize the database name
binlog-ignore-db = mysql # may not be copied from the server library
Restart mysql:
/etc/init.d/mysqld restart
Authorization:
mysql>grant replication slave on . to [email protected] identified by "123456";
MySQL> Grant Slave Replication ON . to Slave @ '%' IDENTIFIED by "123456"; ip can be granted to any synchronization.
View status information:
mysql> show master status;
mysql-master-bin.000001
View binary log:
ls /usr/local/mysql/data/
mysql> show binlog events\G
Before copying To ensure consistent synchronization of databases, export database
mysqldump -uroot -p123456 HA> HA.sql # Export database
Pass from the exported database server
Method a: scp HA.sql [email protected]: / root
or
Remember to empty two servers iptables, or else port can not communicate
iptables –F
/etc/init.d/iptables stop
chkconfig iptables off
mysql2：
Two database servers mysql version to be consistent
mysql> show variables like '%version%';

192.168.146.14 ：
Modify the configuration file from the server:
From the server is not necessary to open the bin-log log
vim /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
Increase Row 1 below:
server-id = 2 # from the server ID number, and not the same as the main ID, if from a plurality of servers, each must have a unique server-id value from the server, the primary server, and must be further from the server is not the same . Server-id value may be considered similar to IP Address: The ID value uniquely identifying each server replicate real server cluster
/etc/init.d/mysqld restart
Test the connection to the primary server is successful
mysql -uslave -p123456 -h 192.168.146.13
Into the database, and consistent with the primary database server
msyql -uroot -p123456
mysql> create database HA;
mysql > use HA;
mysql > source HA < HA.sql
or:
mysql -uroot -p123456 HA < HA.sql
mysql> change master to master_host='192.168.146.13',master_user='slave',master_password='123456';
mysql> start slave;
mysql> show slave status \ G View Status
Yes is the emergence of two normal
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
The above step is done msyql master-slave configuration, if deployed as a main msyql - master configuration need continues as follows:
Two, mysql main master configuration:

192.168.146.14：

Increase log-bin = mysql-bin-master # enable binary logging
server-id= 2 Increase binlog-do-db = HA # can be replicated from the server database. Binary need to synchronize the database name
Increase binlog-ignore-db = mysql # database can not be copied from the server
/etc/init.d/mysqld restart
Authorization:
mysql>grant replication slave on . to [email protected] identified by "123456";
Back mysql1:
mysql> change master to master_host='192. 168.146.14',master_user='slave',master_password='123456';
Third, re-synchronize all the data:
mysql> stop slave；
mysql> delete from test；
Back to the main mysql:
mysql> mysqldump -uroot -p123456 HA> HA.sql # Export database
scp HA.sql [email protected]:/root
Back from mysql:
mysql> mysql -uroot -p123456 HA < HA.sql
mysql> change master to master_host='192.168.146.13',master_user='slave',master_password='123456';
mysql> start slave;
mysql> show slave status \ G View Status
Fourth, resynchronize data of a node:
Main msyql:
mysql> show master status;
Record master_log_file = 'mysql-bin-master.000004' and master_log_pos = 360
From mysql:
mysql> stop slave；
mysql> delete from test；
mysql> change master to master_host='192.168.146.13',master_user='slave',master_password='123456',master_log_file='mysql-bin-master.000004',master_log_pos=360;
mysql> start slave；
