Mysqlbackup 基于binlog 的恢复示例
目录
适用范围
MYSQL 5.7+
方案概述
客户环境，定期对MYSQL做全备，同进每15分钟会对做一个备份，通过Mysqlbackup 全备或增量恢复后，需要对binlog进行前滚，恢复到指定的时间点。
实施步骤
1.备份

8.指定binglog 应用恢复
8.1变更 binlog.index 指向所要恢复的文件
[root@s2ahuoracle02 binlogs]# cat binlog.index
/u01/mysql8e/data/binlogs_bak/binlog.000001
/u01/mysql8e/data/binlogs_bak/binlog.000002
/u01/mysql8e/data/binlogs_bak/binlog.000003
/u01/mysql8e/data/binlogs_bak/binlog.000004
8.2 需要手动flush logs 一次,将需要恢复的binglog 注册到DB
mysql> flush logs ;
Query OK, 0 rows affected (0.03 sec)
mysql> show binary logs;
+---------------+-----------+-----------+
| Log_name | File_size | Encrypted |

| binlog.000002 | 1023 | Yes |
| binlog.000003 | 1023 | Yes |
| binlog.000004 | 705 | Yes |
+---------------+-----------+-----------+
4 rows in set (0.00 sec)
8.3解析binlog
cd /u01/mysql8e/data/binlogs_bak
#指定post位置
mysqlbinlog 26195 --start-position=26195 --read-from-remote-server --host=192.168.1.54 --port=3333 --user=root --password=root --ssl-mode=required binlog.000001 binlog.000002 binlog.000003 binlog.000004 > binlog_post_26195.sql
8.4恢复binlog 数据，并验证
mysql --host=192.168.1.54 --port=3333 --user=root --password=root < binlog_post_26195.sql
mysql> select * from test ;
