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 https://launchpadlibrarian.net/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：

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]#
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: 2017-02-27 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。

mysql> truncate table gyj_t1;

mysql> select * from gyj_t1;

4. 恢复
4.1 恢复
[root@sdw2 ~]# mysql -uroot -p -S /tmp/mysql3310.sock jfedu < /tmp/0301jfedu.dmpEnter 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 201710 end_log_pos 1447 CRC32 0x4e16da5d Anonymous_GTID last_committed=5 sequence_number=6

/*!*/;
SET @@SESSION.GTID_NEXT= 'AUTOMATIC' /* added by mysqlbinlog */ /*!*/;
DELIMITER ;
# End of log file
#按前面 查询的当前时间 2017-03-01 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;

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

+------+----------+
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 https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.3.3/binary/redhat/6/x86_64/percona-xtrabackup-2.3.3-1.el6.x86_64.rpm
