全备之后误删一个表恢复到现在时间点

[root@mysql8-31 mysql]# mysqldump --help
[root@mysql8-31 mysql]# mysqldump -uroot  -A --source-data=2 > /backup/all.sql #默认就是1，主从
CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000008', MASTER_LOG_POS=156;  #从这个点之后找数据

#误删除
mysql> drop table  teachers;

再新增数据
mysql> insert students (name,age)values('c','22');
Query OK, 1 row affected (0.00 sec)

mysql> insert students (name,age)values('d','22');
Query OK, 1 row affected (0.01 sec)

暂停访问
[root@mysql8-31 backup]# head all.sql -n30

生成全备之后二进制文件
[root@mysql8-31 logbin]# mysqlbinlog --start-position=156 /data/mysql/logbin/mysql-bin.000008 > /backup/logbin.sql
[root@mysql8-31 backup]# grep -in drop logbin.sql 
90:DROP TABLE `teachers` /* generated by server */
vim logbin.sql +90
[root@mysql8-31 backup]# sed -n '/^DROP TABLE `teachers`'/p logbin.sql 
DROP TABLE `teachers` /* generated by server */
[root@mysql8-31 backup]# sed -i '/^DROP TABLE `teachers`/d' logbin.sql 

还原验证
