1、binlog备份
[mysql@mysql5 binlog]$mysqlbinlog --read-from-remote-server --raw --host=192.168.1.210 --port=65535 --user=yang --password=oracle --stop-never --result-file=/mysqldb/backup/backup_192.168.1.210/binlog/ master-bin.000001
2、解析binlog
[mysql@mysql5 binlog]$ mysqlbinlog -v -v -v master-bin.000007 > 07.txt
[mysql@mysql5 binlog]$ vi 07.txt
/*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

3、binlog恢复
[mysql@mysql5 binlog]$ mysqlbinlog --start-position=161899 --stop-position=323048 --skip-gtids /mysqldb/db_slave/binlog/slave-bin.000001|mysql -uroot -p -S/mysqldb/db_test01/mysql.sock employees
实验
1、导入employees数据库
2、创建表
mysql> create table test1 like dept_emp;
Query OK, 0 rows affected (0.85 sec)
mysql> alter table test1 drop primary key;
Query OK, 0 rows affected (0.31 sec)
Records: 0 Duplicates: 0 Warnings: 0
mysql> insert into test1 select * from dept_emp limit 10000;
Query OK, 10000 rows affected (0.16 sec)
Records: 10000 Duplicates: 0 Warnings: 0
3、mysqldump备份employees数据库
[mysql@mysql5 db_slave]$ mysqldump -uroot -p -S/mysqldb/db_slave/mysql.sock --master-data=2 --single-transaction --databases employees --set-gtid-purged=off > testdump.sql
Enter password:
4、模拟业务
mysql> insert into test1 select * from dept_emp limit 10000;
Query OK, 10000 rows affected (0.50 sec)
Records: 10000 Duplicates: 0 Warnings: 0
mysql> delete from test1 limit 1000;
Query OK, 1000 rows affected (0.30 sec)
mysql> create table test2 like dept_emp;
Query OK, 0 rows affected (0.27 sec)
5、发现问题进行回滚
MASTER_LOG_POS=161899
at 323048
[mysql@mysql5 binlog]$ mysqlbinlog -v -v -v slave-bin.000001 > 1.txt
[mysql@mysql5 binlog]$ vi 1.txt
[mysql@mysql5 db_slave]$ vi testdump.sql
mysql> source /mysqldb/db_slave/testdump.sql #空实例中#
[mysql@mysql5 binlog]$ mysqlbinlog --start-position=161899 --stop-position=323048 --skip-gtids /mysqldb/db_slave/binlog/slave-bin.000001|mysql -uroot -p -S/mysqldb/db_test01/mysql.sock employees
5、结果
6、导入删除数据
[mysql@mysql5 ~]$ mysqldump -uroot -p -S /mysqldb/db_test01/mysql.sock employees test1 --where="1=1 limit 1000;" --set-gtid-purged=OFF > test3.sql
Enter password:
[mysql@mysql5 ~]$ vi test3.sql
[mysql@mysql5 ~]$ mysql -uroot -p -S /mysqldb/db_slave/mysql.sock --database=employees --table=test1 < test3.sql
mysql: [Warning] mysql: ignoring option '--table' due to invalid value 'test1'
Enter password
