使用的mysql版本：mysql4.0.X

master: 192.168.1.102

slave:    192.168.1.109

如果是win机子修改c:\winnt\my.ini 如果是linux的机子请修改 /etc/my.cnf

一、master操作

1、修改my.ini

##############

server-id=1

log-bin=c:\mysql\logs\mysql_binary_log

binlog-do-db=test

binlog-ignore-db=mysql

##############

说明

binlog-do-db=test                  允许同步的数据库

binlog-ignore-db=mysql      不允许同步的数据库

2、然后重启mysql

c:\mysql\bin\mysql restart  或 /etc/init.d/mysql restart

3、在master上增加一个同步的用户名

mysql> GRANT REPLICATION SLAVE ON *.* TO 'backup'@'%' IDENTIFIED BY '123456';

注:

如果mysql版本在4.0.2以前的版本请用

mysql> GRANT FILE ON *.* TO 'backup'@'%' IDENTIFIED BY '123456';

4、接下来操作要master上要同步的数据库

mysql> USE test;

mysql> FLUSH TABLES WITH READ LOCK;       #锁定要同步的test表，然后导出数据结构

执行如下命令查看master的状态

mysql> SHOW MASTER STATUS;

得到如下结果

Code:

+----------------------+----------+--------------+------------------+

| File                 | Position | Binlog_do_db | Binlog_ignore_db |

+----------------------+----------+--------------+------------------+

| mysql_binary_log.025 | 796947     | test            |  mysql              |

+----------------------+----------+--------------+------------------+

1 row in set (0.00 sec)

接下来备份要同步数据库(为导入slave作准备)

$ mysqldump --opt test > test.sql

mysql> UNLOCK TABLES;                   #已做好同步数据库结构导出后，解锁这个表

二、slave操作

1、把master里导出的同步数据库结构再导入slave的mysql里

mysql tes < test.sql

2、修改slave的my.ini

####################

log-bin=c:\mysql\logs\mysql_binary_log

server-id=2

master-host=192.168.1.102

master-user=backup

master-password=123456

master-connect-retry=60

replicate-do-db=test

####################

说明：

master-host=192.168.1.102                #master的IP

master-user=backup                            #master上作为同步用的用户名

master-password=123456                 #同步用户名的密码

master-connect-retry=60                     #设置同步的时间

replicate-do-db=test                             #需要同步的数据库

3、重新启用mysql

c:\mysql\bin\mysql restart  或 /etc/init.d/mysql restart

4、进入slave的mysql，对mysql进行操作

mysql> stop slave;                  #停止slave服务器

mysql> CHANGE MASTER TO

->     MASTER_HOST='192.168.1.102',

->     MASTER_USER='backup',

->     MASTER_PASSWORD='123456',

->     MASTER_LOG_FILE='mysql_binary_log.025',

->     MASTER_LOG_POS=796947;

mysql> START SLAVE;         #开启slave服务器就可以同步了

注：

MASTER_LOG_FILE='mysql_binary_log.025',

MASTER_LOG_POS=796947;

上面这两条是一开始从master上进入mysql，运行 SHOW MASTER STATUS; 查看到的,在实际操作中也可以不加的。

##############################################

在master的mysql里运行

mysql > show processlist;

看到两个 system user 就是正常的
