主主复制，亦可称为互为主从，主主互备或双机热备

1. 配置互为主从 (my.cnf)
2. 查看两台数据库配置情况
3. 建立权限帐户，实现同步
4. 测试同步效果

1. 配置互为主从 (my.cnf)

2. 查看两台数据库配置情况

NO1:Master1(192.168.187.129)的情况

# mysql –u root –p 1234  
mysql> show master status;  
  
+------------------+----------+--------------+------------------+  
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |  
+------------------+----------+--------------+------------------+  
| mysql-bin.000001|      107 | test         | mysql            |  
+------------------+----------+--------------+------------------+

NO2:Master2(192.168.187.132)的情况

# mysql –u root –p 1234  
mysql> show master status;  
  
+------------------+----------+--------------+------------------+  
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |  
+------------------+----------+--------------+------------------+  
| mysql-bin.000002|      125 | test         | mysql            |  
+------------------+----------+--------------+------------------+

3. 建立权限帐户，实现同步

4. 测试同步效果

在Master1上创建表

mysql -uroot -p1234;  
  
use test;  
  
CREATE TABLE `card` (  
   `card_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'ID',  
   `card_number` varchar(100) DEFAULT NULL COMMENT '卡号',  
   PRIMARY KEY (`card_id`)  
 ) ENGINE=MyISAM DEFAULT CHARSET=utf8 CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC;  
  
insert  into `card`(`card_number`) values ('haha1');  
insert  into `card`(`card_number`) values ('haha2');
