使用mysqlbinlog從mysql數據庫表中的特定日期恢復數據

我有從2016-01-01（Jan）到2016-06-29（June）數據的名爲「radacct」的mysql數據庫表。由於某些原因，2016年6月20日至2016年6月25日的數據丟失。我有bin-log enabled，所以我用「mysqlbinlog」將bin文件導出到.sql文件，這些sql文件包含了從1月，2月，3月的舊數據......以及2016-06-20到2016-06丟失的數據-25。如何在不丟失當前數據的情況下恢復丟失的數據。使用mysqlbinlog從mysql數據庫表中的特定日期恢復數據

我正在考慮選擇包含缺失數據的文件（我使用日期字段來標識缺失的數據），並用REPLACE INTO替換INSERT INTO。

繼承人的SQL文件是什麼樣子

可以使用mysqlbinlog --start-datetime="2016-01-01 00:00:00" --stop-datetime="2016-06-29 23:59:59" <log file> > <sql file path>

創建MySQL的二進制日誌文件測試，但它也將包括舊數據中已經存在。 –

從某種意義上講，較早的數據是在01年1月1日至16日和6月30日之間？ –

是的，它也有數據在2016-01-01 00:00:00之前插入 –

我無法恢復被刪除表的數據[data from specific days of the month eg. day 11,12,13]與二進制日誌，而且從中學到有益的步驟，過程中可能是有用的可能的數據庫故障

The MariaDB server's binary log is a set of files containing "events" 
which represent modifications to the contents of a MariaDB database. 
These events are written in a binary (i.e. non-human-readable) format. 
The mysqlbinlog utility is used to view these events in plain text. 
Note: binary logging should be enabled on mysql server. to enable it edit my.cnf file and under "[mysqld]" section 
[mysqld] 
.... 
log-bin 
....

重新啓動mysql服務。現在你將不得不在/ var/lib中/ mysql目錄

For example if there are few binlog files like 
ls -1 /var/lib/mysql 
mysql-bin.000051 
mysql-bin.000052 
mysql-bin.000053 
mysql-bin.000054 

the sql file can be generated for those bin files and then later be imported into database 

mysqlbinlog mariadb-bin.000051 > /tmp/mariadb-bin51.sql 
mysqlbinlog mariadb-bin.000052 > /tmp/mariadb-bin51.sql 
... 
OR 
for i in `seq 51 58`;do mysqlbinlog mysql-bin.0000${i} > ${i}-log.sql ; sleep 1 ;done
