mysql双主同步

Mysql 5.6.23

CENTOS 6.4 X86

目标: 两个MYSQL主机进行数据同步

NODE1:192.168.59.230

NODE2:192.168.59.231

配置先简单

NODE1配置:

 

Step1. Change /etc/my.cnf

 

[mysqld]

 

log-error=/var/log/mysql/mysql.log

 

auto_increment_increment=2

auto_increment_offset=1

 

server-id=1

log-bin=mysql-bin

binlog_format=ROW

 

 

Step2. Login in Mysql

 

mysql -uroot -padmin

 

mysql> grant replication slave on *.* to 'replication'@'%' identified by 'slave';

 

mysql> change master to master_host='192.168.59.231',

    -> master_user='replication',

    -> master_password='slave',

    -> master_log_file='mysql-bin.000001',

    -> master_log_pos=0;

Query OK, 0 rows affected, 2 warnings (0.11 sec)

 

 

mysql> start slave;

 

mysql> show master status;
