HomeDatabaseMysql TutorialMYSQL5 masterslave数据同步配置方法第1/3页

因线路或安全需要我们不得不考虑mysql的备份,特把mysql数据备份的方法整理下。

测试环境.基本上数据是瞬间同步,希望对大家有帮助
RedHat ES 3 update 3
MYSQL 5.0.15
MYSQL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

  导出Master的数据库到slave的机器,可以选择导出需要同步的数据库

  在A机器上修改/etc/my.cnf

  在[mysqld]区段内加入参数

  log-bin=mysql-bin

  server-id=1

  binlog_do_db = gbbbs(要同步的数据库)

  binlog_ignore_db = mysql,test,information_schema (不需要同步的库,5.0 有information_schema这个库)

  sql-bin-update-same

  重启A服务器mysql

  B服务器设置

  设定/etc/my.cnf

  在[mysqld]区段加入

  server-id = 2 (如果还有slave用户,他们的ID也随之增加,如server-id=3)

  master-host = 192.168.112.71

  master-user = backup

  master-password = 1234

  replicate-do-db = gbbbs

  #replicate-do-db = database2

  log-warnings

  master-port=3306

  master-connect-retry = 60

  重启B服务器的MYSQL

  在数据库的文件夹里有master.info文件,用来查看同步信息

  其实就是MYSQL Replication
