  MYSQL的master/slave数据同步配置
  
  我的测试环境.基本上数据是瞬间同步,希望对大家有帮助
  
  redhat 9.0
  mysql3.23.57
  
  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
  
  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.
  
  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?!

How to recover data after SQL deletes rows How to recover data after SQL deletes rows Apr 09, 2025 pm 12:21 PM

Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.
