求助 mysql 数据同步

[defoliation]

我有两台 sql服务器 版本为 mysql4.1

我按照chianunix上的做法
/*----------------------------------chinaunix 上的做法------------------------------------*/
sql数据同步备份

A服务器： 192.168.1.2 主服务器master
B服务器： 192.168.1.3 副服务器slave
A服务器设置
#mysql –u root –p
mysql>GRANT FILE ON *.* TO backup@192.168.1.3 IDENTIFIED BY ‘1234’;
mysql>\exit

上面是Master开放一个账号backup密码1234给IP:192.168.1.3有档案处理的权限


mysqladmin –u root –p shutdown

备份Master所有数据库..通常都用tar指令.
#tar –cvf /tmp/mysql.tar /var/lib/mysql
注意:tar的时候,MySQL是要在stop情况下

在A机器上修改/etc/my.cnf
在[mysqld]区段内加入参数
log-bin
server-id=1
sql-bin-update-same
binlog-do-db=vbb

重启A服务器mysql

此时因为有加入log-bin参数,因此开始有index产生了,在/var/lib/mysql目录下有.index档案纪录数据库的异动log.


B服务器设置

设定/etc/my.cnf
在[mysqld]区段加入

master-host=192.168.1.2
master-user=backup
master-password=1234
master-port=3306
server-id=2
master-connect-retry=60 预设重试间隔60秒
replicate-do-db=vbb 告诉slave只做vbb数据库的更新
log-slave-updates


将A上的mysql.tar copy到B上
用ftp传B的/tmp
9.解压缩
#cd /var/lib/


状况测试
1.A跟B网络及服务都正常情况下,由A端变化数据后,到B端浏览数据,检视是否有进行replication?!
2.模拟B当机,或是B不一定需要一直跟A有连接.
将由A端变化数据后,到B端浏览数据，B点应该是没有数据变化的


#tar xvf /tmp/mysql-snapshot.tar
#chown –R mysql:mysql mysql

1重启B服务器的mysql

这时在/var/lib/mysql目录会出现master.info,此档案纪录了Master MySQL server的信息.

这一步我没有做 "
将A上的mysql.tar copy到B上
用ftp传B的/tmp
9.解压缩
#cd /var/lib/

"
我只是在两台机器上建立相同的数据库

请教个位高手,我为什么没有成功,
我的一台机器为固定IP 一台为动态 IP
