MySQL数据库恢复(使用mysqlbinlog命令)

發布時間：2025/3/15 数据库 14 豆豆

生活随笔收集整理的這篇文章主要介紹了 MySQL数据库恢复(使用mysqlbinlog命令) 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1：開啟binlog日志記錄?
修改mysql配置文件mysql.ini，在[mysqld]節點下添加?

復制代碼代碼如下:
# log-bin?
log-bin = E:/log/logbin.log?

路徑中不要包含中文和空格。重啟mysql服務。通過命令行停止和啟動mysql服務?

復制代碼代碼如下:
c:\>net stop mysql;?
c:\>net start mysql;?

進入命令行進入mysql并查看二進制日志是否已經啟動?
Sql代碼?

復制代碼代碼如下:
mysql>show variables like 'log_%';?

日志成功開啟后，會在E:/log/目錄下創建logbin.index和logbin.000001兩個文件。logbin.000001就是數據庫的備份文件，以后就可以通過此文件對數據庫進行恢復操作。?

2：查看備份的二進制文件?
Sql代碼?

復制代碼代碼如下:
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001?

日后記錄的操作多了，命令行方式基本就用不上了。可以使用將日志導出文件的方式來查看日志內容?
2.1 導出?
Xml代碼?

復制代碼代碼如下:
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001 > e:/log/log.txt?

">": 導入到文件中; ">>": 追加到文件中?
如果有多個日志文件?
Sql代碼?

復制代碼代碼如下:
c:\mysql\bin\> mysqlbinlog e:/log/logbin.000001 > e:/log/log.sql?
c:\mysql\bin\> mysqlbinlog e:/log/logbin.000002 >> e:/log/log.sq?

2.2 按指定位置導出：?
Sql代碼?

復制代碼代碼如下:
c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 > e:/log/log3.txt?

2.3 按指定時間導出：?
Xml代碼?

復制代碼代碼如下:
c:\mysql\bin\>mysqlbinlog --start-datetime="2010-01-07 11:25:56" --stop-datetime="2010-01-07 13:23:50" e:/log/logbin.000001 > e:/log/log_by_date22.txt?

3：從備份恢復數據庫?
做了一次更新操作，之后日志的內容如下：?
Sql代碼?

復制代碼代碼如下:

/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;?
