做开发的时候要做MySQL的数据库同步,两台安装一样的系统,都是FreeBSD5.4,安装了Apache 2.0.55和PHP 4.4.0,MySQL的版本是4.1.15,都是目前最新的版本。 1. 安装配置 两台服务器,分别安装好MySQL,都安装在 /usr/local/MySQL 目录下(安装步骤省略,请参考

   做开发的时候要做MySQL的数据库同步,两台安装一样的系统,都是FreeBSD5.4,安装了Apache 2.0.55和PHP 4.4.0,MySQL的版本是4.1.15,都是目前最新的版本。

  1. 安装配置

  两台服务器,,分别安装好MySQL,都安装在 /usr/local/MySQL 目录下(安装步骤省略,请参考相关文档),两台服务器的IP分别是192.168.0.1和192.168.0.2,我们把192.168.0.1作为master数据库,把192.168.0.2作为slave服务器,我们采用单向同步的方式,就是master的数据是主的数据,然后slave主动去master哪儿同步数据回来。

  两台服务器的配置一样,我们把关键的配置文件拷贝一下,默认的配置文件是在 /usr/local/MySQL/share/MySQL目录下,分别有 my-large.cnf, my-medium.cnf, my-small.cnf等几个文家,我们只是测试,使用my-medium.cnf就行了。MySQL安装完后,默认的配置文件是指定在数据库存放目录下的,我们用的是4.1.X的,所以配置文件就应该在 /usr/local/MySQL/var 目录下,于是把配置文件拷贝过去:

  cp /usr/local/MySQL/share/MySQL/my-medium.cnf /usr/local/MySQL/var/my.cnf

  两台服务器做相同的拷贝配置文件操作。

  2. 配置Master服务器

  我们要把192.168.0.1配置为主MySQL服务器(master),那么我们就要考虑我们需要同步那个数据库,使用那个用户同步,我们这里为了简单起见,就使用root用户进行同步,并且只需要同步数据库abc。

  打开配置文件:

  vi /usr/local/MySQL/var/my.cnf

  找到一下信息:

  # required unique id between 1 and 2^32 - 1# defaults to 1 if master-host is not set# but will not function as a master if omittedserver-id = 1 //1为master,2为salve

  添加两行:

  sql-bin-update-same //同步形式binlog-do-db = abc //要同步的数据库

  重启192.168.0.1的MySQL服务器:

  /usr/local/MySQL/bin/MySQLadmin shutdown/usr/local/MySQL/bin/MySQLd_safe --user=MySQL &

  3. 配置Slave服务器

  我们的slave服务器主要是主动去master服务器同步数据回来,我们编辑配置文件:

  vi /usr/local/MySQL/var/my.cnf
