mysqldumper 与 Innobackupex的备份和恢复操作实验过程

一、mysqldumper

1.1 mysqldumper 编译安装

wget /185032423/mydumper-0.6.2.tar.gz

[root@mdw tang]# tar -zxvf mydumper-0.6.2.tar.gz

[root@mdw tang]# cd mydumper-0.6.2

[root@mdw mydumper-0.6.2]# yum install pcre-devel.x86_64

[root@mdw mydumper-0.6.2]# mkdir bin

[root@mdw mydumper-0.6.2]# cd bin

[root@mdw bin]# cmake ../

报错,提示没有支持包:

-- checking for one of the modules 'glib-2.0'

-- checking for one of the modules 'gthread-2.0'

查看官方介绍

/mydumper/+faq/349

找到:

Ubuntu or Debian: apt-get install libglib2.0-dev libmysqlclient15-dev zlib1g-dev libpcre3-dev libssl-dev

安装支持包:

yum install glib2-devel mysql-devel zlib-devel pcre-devel openssl-devel

[root@mdw bin]# cmake ../

1.2 备份全库

[root@mdw bin]# ./mydumper -u root -p sa123 -S /tmp/mysql3306.sock -o /opt/backup/all_database_0227.dmp

备份出来的sql 文件,是以数据开关.表名[-schema].sql 为名。有带[-schema]的为表结构创建语句,没有的

为表数据插入语句。

[root@mdw bin]# ll /opt/backup/all_database_0227.dmp/

metadata这个文件记录的是当里的binlog文件及pos,可以使用这个信息搭建slave.

[root@mdw bin]# cat /opt/backup/all_database_0227.dmp/metadata

Started dump at: -02-27 16:37:52

SHOW MASTER STATUS:

二、误操作truncate table gyj_t1;利用mysqldump的备份和binlog日志对表gyj_t1做完全恢复

2.1 备份前查看binlog文件。

3.1 备份后,做数据插入及清空表操作

mysql> insert into gyj_t1 values(4,'dumped 4');

Query OK, 1 row affected (0.01 sec)

| 3 | dumped 3 |

| 4 | dumped 4 |

+------+----------+

4 rows in set (0.00 sec)

mysql> truncate table gyj_t1;

Query OK, 0 rows affected (0.01 sec)

mysql> select * from gyj_t1;

mysql> select now();

+---------------------+

1 row in set (0.00 sec)

mysql> truncate table gyj_t1;

Query OK, 0 rows affected (0.07 sec)

mysql> select * from gyj_t1;

Empty set (0.00 sec)

4. 恢复

4.1 恢复

[root@sdw2 ~]# mysql -uroot -p -S /tmp/mysql3310.sock jfedu < /tmp/0301jfedu.dmp

Enter password:

4.2 查看恢复后的数据:

mysql> mysql> select * from gyj_t1;

+------+--------+

| id | name |

+------+--------+

| 1 | AAAAA |

| 2 | BBBBBB |

+------+--------+

2 rows in set (0.00 sec)

只有备份前的数据

4.3 使用mysqlbinlog 恢复

[root@sdw2 ~]# mysqlbinlog '/opt/mysql/data/mysql-bin.000008' > gyj.sql

[root@sdw2 ~]# vi gyj.sql

#170301 14:34:14 server id 10 end_log_pos 1447 CRC32 0x4e16da5d Anonymous_GTID last_committed=5 sequence_number=6

SET @@SESSION.GTID_NEXT= 'ANONYMOUS'/*!*/;

# at 1447

#170301 14:34:14 server id 10 end_log_pos 1536 CRC32 0x30efcd28 Query thread_id=20 exec_time=47 error_code=0

SET TIMESTAMP=1488407654/*!*/;

SET @@session.sql_mode=1075838976/*!*/;

truncate table gyj_t1

/*!*/;

SET @@SESSION.GTID_NEXT= 'AUTOMATIC' /* added by mysqlbinlog */ /*!*/;

DELIMITER ;

# End of log file

#按前面 查询的当前时间 -03-01 14:33:58 查询到truncate 语句是在 end_log_pos 1536 后。可以恢复可以恢复到这个点。

4.3 按时间恢复

[root@sdw2 ~]# mysql -uroot -p -S /tmp/mysql3310.sock jfedu < /tmp/0301jfedu.dmp

Enter password:

mysqlbinlog '/opt/mysql/data/mysql-bin.000008' --start-position=1036 --stop-position=1447 |mysql -uroot -p -S /tmp/mysql3310.sock

(前几次按时间点恢复失败,主要原因是我没想到,最后一次使用 备份/tmp/0301jfedu.dmp 做恢复时,也是会写到binlog日志中的,

没指定恢复时间段范围,其实是又把恢复重做了一次。最后添加的数据还是没有出来)

#再次查询,发现数据已恢复。

mysql> select * from gyj_t1;

+------+----------+

| id | name |

+------+----------+

| 1 | a name |

| 2 | b name |

| 3 | dumped 3 |

| 4 | dumped 4 |

+------+----------+

三、利用Innobackupex的备份和binlog日志对MySQL数据库做完全恢复。

误操作MySQL数据库:rm /u01/my3306/data/*; 再利用Innobackupex的备份和binlog日志对MySQL数据库做完全恢复。

wget /downloads/XtraBackup/Percona-XtraBackup-2.3.3/binary/redhat/6/x86_64/percona-xtrabackup-2.3.3-1.el6.x86_64.rpm

yum install percona-xtrabackup-2.3.3-1.el6.x86_64.rpm
