log-bin=”E:/Mysql57BinLog/binlog”(windows下的路径，linux下自行修改路径)
expire_logs_days=10
max_binlog_size=100M

使用命令show VARIABLES like ‘%log_bin%’;查看

create database mytest;

use mytest;
create table t(a int PRIMARY key)ENGINE = INNODB DEFAULT CHARSET=utf8;

flush logs;

flush logs，刷新二进制日志后会多出来一个二进制日志

使用命令查看二进制日志内容

默认会读取配置文件，检测到no–beep会报错。

推荐使用命令：mysqlbinlog –no-defaults E:\Mysql57BinLog\binlog.000001

use mytest;
insert into t select 1 union all select 2 union all select 3;

flush logs;

 

drop database mytest;

flush logs;

mysqlbinlog –no-defaults E:\Mysql57BinLog\binlog.000001 E:\Mysql57BinLog\binlog.000002 E:\Mysql57BinLog\binlog.000003 | mysql -u root -p

数据已还原。

———————————–华丽的分割线————————————————————–

create table t2(a int PRIMARY key)ENGINE=INNODB default CHARSET=utf8;

insert into t2 values(1),(2),(3),(4),(5);

>mysqlbinlog –no-defaults E:\Mysql57BinLog\binlog.000006

删除数据

delete from t2 where a < 4;

恢复数据

drop database mytest;

删除库mytest，回到最原始的地方

mysqlbinlog –no-defaults –start-position=”4″ –stop-position=”1285″ E:\Mysql57BinLog\binlog.000006  | mysql -u root -p

 

数据恢复成功。
