mysql利用phpmyadmin实现数据库同步更新

phpmyadmin

以前我们设置数据同步更新需要两台mysql数据库实现主从配置了,下面我来介绍高版本的phpmyadmin就可以快速实现这个功能了,下面我以图文给大家介绍。

台作为从服务器来实现的。在这里我把我做的过程共享一
下,有不对的地方,往各网友指出.
系统:centos linux服务器一台 IP:192.168.0.8 windows2003服
务器一台IP:192.168.0.9
软件:centos linux 服务器安装一台mysql-server5.0 windows2003
安装一个叫Apmserv软件自带一个mysql5.1,phpmyadmin(图形
管理MYSQL数据库)
一,先在主服务建立一个用户,用来同步数据所用,我这里采
用一个图型管理MYSQL数据库软件来建立(phpmyadmin)
在这里注意一点:这个用户管理权限一定要有replicaiion

slave 既是复制权限:

 

二,我用在从服务器windows2003用刚建的用户admin是否可以

 

连接到linux(主服器)Apmserv用法我在这里不作详细说明。

 

在从服务器中运行:mysql -h 192.168.0.8 -u admin -p 然后输入密码

注意:因为在mysql这个命定在windos系统下是没有的,所以要加一个环境变量)

三,配置主服务器配置文件:vim /etc/my.cnf

server-id=1

log-bin

 

这二行是新加的

重启mysql

 

mysql -u root -p

 

show master status;

(这样表明主服务器配置成功)

 

四,从服务器配置文件也是my.cnf

server-id=2 从服务器ID号

master-host 主服务器地址

master-port 端口号

master-user 复制需要的用户名

master-password 复制需要的用户名所对应密码

replicate-do-db 所需要复制的数据库

然后重启数据库

mysql>show slave statusG;

主从服务器分别新建一个test1数据库,在主服务器数据插入数 据从服务器可以马上同步的到. * 主服务器IP地址改变时,从服务器。要实现同步只修改/etc/my.cnf是没有用的。需要用到以下命令:

 

stop slave;
reset slave;
change master to
MASTER_HOST='master_ip',
-> MASTER_USER='replication_user_name',
-> MASTER_PASSWORD='replication_password',
-> MASTER_LOG_FILE='recorded_log_file_name',
-> MASTER_LOG_POS=recorded_log_position;

 

start slave;

替换其中的master_ip,master_user,master_password为master ip地址,具有复制权限的用户,密码
把recorded_log_file_name替换为上面记录的file,recorded_log_position为上面记录的position
