1:開啟binlog日誌記錄
修改mysql設定檔mysql.ini,在[mysqld]節點下添加
複製代碼 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。通過命令列停止和啟動mysql服務 複製代碼 代碼如下:c:\>net stop mysql;
c:\>net start mysql;
進入命令列進入mysql並查看二進位日誌是否已經啟動
Sql代碼 複製代碼 代碼如下:mysql>show variables like 'log_%';
日誌成功開啟後,會在E:/log/目錄下建立logbin.index和logbin.000001兩個檔案。logbin.000001就是資料庫的備份檔案,以後就可以通過此檔案對資料庫進行恢複操作。
2:查看備份的二進位檔案
Sql代碼 複製代碼 代碼如下:c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001
日後記錄的操作多了,命令列方式基本就用不上了。可以使用將日誌匯出檔案的方式來查看日誌內容
2.1 匯出
Xml代碼 複製代碼 代碼如下:c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001 > e:/log/log.txt
">": 匯入到檔案中; ">>": 追加到檔案中
如果有多個記錄檔
Sql代碼 複製代碼 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 按指定位置匯出:
Sql代碼 複製代碼 代碼如下:c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 > e:/log/log3.txt
2.3 按指定時間匯出:
Xml代碼 複製代碼 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:從備份恢複資料庫
做了一次更新操作,之後日誌的內容如下:
