mysql 利用二进制日志进行数据恢复(mysqlbinlog)

老大让在windows下安装mysql服务（mysql免安装版http://download.softagency.net/MySQL/Downloads/MySQL-5.1/）

查看当前正在写的日志文件：mysql show master status 

mysql> show master status;
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000002 |      907 |              |                  |
+------------------+----------+--------------+------------------+

用mysqlbinlog命令导出可理解的文本文档：（两句都一样，下边的-r是--result-file参数的别名）

D:\mysql5163\data>mysqlbinlog --result-file=D:/result2.txt mysql-bin.000002

D:\mysql5163\data>mysqlbinlog -rD:/result2.txt mysql-bin.000002

用记事本打开result2.txt

# at 221
#120619 16:06:00 server id 1  end_log_pos 323     Query    thread_id=1    exec_time=0    error_code=0
SET TIMESTAMP=1340093160/*!*/;
insert into test value(1,12,'zhangsan')
/*!*/;
# at 323
#120619 16:26:13 server id 1  end_log_pos 421     Query    thread_id=1    exec_time=0    error_code=0
SET TIMESTAMP=1340094373/*!*/;
insert into test value(2,12,'lisi')
/*!*/;

按位置恢复（按日期恢复时，老提示我日期有错误，不合格）第一条：

D:\mysql5163\data>mysqlbinlog --start-position=221 --stop-position=323 mysql-bin.000002 | mysql -uroot

注意：1.恢复一条时用这一条的两边的两个at后的值（#at 221 #at 323）当然 也可以用相应的end_log_pos来定位某条语句或某几条语句

2.参数和命令跟 Linux下一样（mysqlbinlog -help）

3.我的二进制日志存放在数据库目录下（默认的路径），我的mysqlbinlog 命令是在日志文件的目录下敲的，如果你不是的话可以将目录补全

 找到了，实验成功：通过日期进行恢复，使用的是双引号（http://www.cnblogs.com/xionghui/archive/2012/03/11/2389792.html）

>mysqlbinlog --start-datetime="2009-09-14 0:20:00" --stop-datetim="2009-09-15 01:25:00" /diskb/bin-logs/xxx_db-bin.000001 | mysql -u root

ps:命令帮助

 --start-datetime=name
                     Start reading the binlog at first event having a datetime
                     equal or posterior to the argument; the argument must be
                     a date and time in the local time zone, in any format　　//任何mysql能接收的日期格式
                     accepted by the MySQL server for DATETIME and TIMESTAMP
                     types, for example: 2004-12-25 11:25:56 (you should
                     probably use quotes for your shell to set it properly). //最好用引号(双引号)
 -j, --start-position=#
                     Start reading the binlog at position N. Applies to the
                     first binlog passed on the command line.
