mysql Synchronize

MySQL数据同步主要有三种方式: 1.利用MySQL自身的数据库同步功能 2.利用MySQL数据库的特性(数据库存在固顶目录,并且以文件形式存储),进行数据库目录同步以达到数据同步目的 3.利用专用的MySQL数据库同步软件


1.利用MySQL自身的数据库同步功能(下面参考自网上的文章,写的非常详细了)
MySQL从3.23.15版本以后提供数据库复制功能。利用该功能可以实现两个数据库同步,主从模式,互相备份模式的功能.

数据库同步复制功能的设置都在mysql的设置文件中体现。mysql的配置文件(一般是my.cnf),在unix环境下在/etc/mysql/my.cnf或者在mysql用户的home目录下的my.cnf。

windows环境中,如果c:根目录下有my.cnf文件则取该配置文件。当运行mysql的winmysqladmin.exe工具时候,该工 具会把 c:根目录下的my.cnf命名为mycnf.bak。并在winnt目录下创建my.ini。mysql服务器启动时候会读该配置文件。所以可以把 my.cnf中的内容拷贝到my.ini文件中,用my.ini文件作为mysql服务器的配置文件。

  设置方法:
设置范例环境:
(天天网络禁止字符)作系统:window2000professional
mysql:4.0.4-beta-max-nt-log
Aip:10.10.10.22
Bip:10.10.10.53
A:设置
1.增加一个用户最为同步的用户帐号:
GRANTFILEON*.*TObackup@'10.10.10.53'IDENTIFIEDBY‘1234'
2.增加一个数据库作为同步数据库:
createdatabasebackup
B:设置
1.增加一个用户最为同步的用户帐号:
GRANTFILEON*.*TObackup@'10.10.10.22'IDENTIFIEDBY‘1234'
2.增加一个数据库作为同步数据库:
createdatabasebackup
主从模式:A->B
A为master
修改Amysql的my.ini文件。在mysqld配置项中加入下面配置:
server-id=1
log-bin
#设置需要记录log可以设置log-bin=c:mysqlbakmysqllog设置日志文件的目录,
#其中mysqllog是日志文件的名称,mysql将建立不同扩展名,文件名为mysqllog的几个日志文件。
binlog-do-db=backup#指定需要日志的数据库
重起数据库服务。
用showmasterstatus命令看日志情况。
B为slave start slave
修改Bmysql的my.ini文件。在mysqld配置项中加入下面配置:
server-id=2
master-host=10.10.10.22
master-user=backup#同步用户帐号
master-password=1234
master-port=3306
master-connect-retry=60预设重试间隔60秒
replicate-do-db=backup告诉slave只做backup数据库的更新
重起数据库
用showslavestatus看同步配置情况。
注意:由于设置了slave的配置信息,mysql在数据库目录下生成master.info
所以如有要修改相关slave的配置要先删除该文件。否则修改的配置不能生效。
双机互备模式。
如果在A加入slave设置,在B加入master设置,则可以做B->A的同步。
在A的配置文件中mysqld配置项加入以下设置:
master-host=10.10.10.53
master-user=backup
master-password=1234
replicate-do-db=backup
master-connect-retry=10
在B的配置文件中mysqld配置项加入以下设置:
log-bin=c:mysqllogmysqllog
binlog-do-db=backup
注意:当有错误产生时*.err日志文件。同步的线程退出,当纠正错误后要让同步机制进行工作,运行slavestart
重起AB机器,则可以实现双向的热备。
测试:
向B批量插入大数据量表AA(1872000)条
A数据库每秒钟可以更新2500条数据。


2.数据库目录同步,方法和文件同步一样,设置好需要同步的两个数据库目录就可以了!
缺点很明显,数据同步只能单向进行,可以作为备份方案

3.用专用的MySQL同步软件进行同步
这方面的软件有SQLBalance和MyReplicator,优点是方便直观,还有很多争强功能!
缺点和2一样,只能单项同步!
当然你也可以修改镜像网站的程序为提交数据到母数据库,读取则在当前镜像下的数据,不过,修改起来麻烦!普通用户修改也非常难!呵呵,大家了解一下就可以!给大家一个思路!有能力的朋友可以试试阿!

4.关于MySQL论坛的数据同步
由于数据来源的不可控制(不好表达),论坛数据是实时的,而且还要考虑来自镜像论坛的数据,如何实现镜像论坛与母论坛数据同步呢?
用1中介绍的MySQL自带的数据库同步功能互相备份模式就可以实现的!
不过,具体的应用我没有测试!稳定性不敢保证!
有能力的朋友推荐用下面这种思路来同步,相对来说减少点效率,但能减少发生的错误!
比如镜像论坛数据同步:
1.母论坛和镜像论坛的数据全写在母论坛数据库里,主从模式,读取只在本地读取,这个需要修改程序!

2.每次写数据,都同时提交到两个数据库中,安全,但是效率很差,也得修改程序
