MySQL利用mysqlbinlog命令恢復誤刪除數據（運維技術交流群：926402931，歡迎大家一起來交流。）

目錄

• 1.MySQL開啟binlog功能
• 2.登錄到資料庫
• 3.創建與刪除資料庫
• 4.查看binlog日誌
• 5.恢複數據

1.MySQL開啟binlog功能

log-error=/var/log/mysql.log
log-bin=/data/binlog/mysql-bin
sync_binlog=1
binlog_format=row

2.登錄到資料庫

[root@db01 ~]# mysql -uroot -p123

3.創建與刪除資料庫

mysql> create database xiaohai;
mysql> drop database xiaohai;

4.查看binlog日誌

[root@db01 binlog]# mysqlbinlog mysql-bin.000008
# at 1200
#200409 16:41:36 server id 10  end_log_pos 1297 CRC32 0x84e92ac7 	Query	thread_id=8   exec_time=0	error_code=0
SET TIMESTAMP=1586421696/*!*/;
create database xiaohai
/*!*/;
# at 1297
#200409 16:42:24 server id 10  end_log_pos 1384 CRC32 0xfdf1d747 	Query	thread_id=8   exec_time=0	error_code=0
SET TIMESTAMP=1586421744/*!*/;
drop database xiaohai
/*!*/;
DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET COMPLETION_TYPE=@OLD_COMPLETION_TYPE*/;
/*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=0*/;

5.恢複數據

[root@db01 binlog]# mysqlbinlog mysql-bin.000008 --start-position=1200 --stop-position=1297>test.sql
mysql> source /data/binlog/test.sql;
mysql> show databases;
