MySQL innodb引擎备份工具XtraBackup之二（数据库全备）

Xtrabackup备份原理：

在InnoDB内部会维护一个redo日志文件，我们也可以叫做事务日志文件。事务日志会存储每一个InnoDB表数据的记录修改。当InnoDB启动时，InnoDB会检查数据文件和事务日志，并执行两个步骤：它应用(前滚)已经提交的事务日志到数据文件，并将修改过但没有提交的数据进行回滚操作。

xtrabackup在启动时会记住log sequence number(LSN)，并且复制所有的数据文件。复制过程需要一些时间，所以这期间如果数据文件有改动，那么将会使数据库处于一个不同的时间点。这时，xtrabackup会运行一个后台进程，用于监视事务日志，并从事务日志复制***的修改。xtrabackup必须持续的做这个操作，是因为事务日志是会轮转重复的写入，并且事务日志可以被重用。所以xtrabackup自启动开始，就不停的将事务日志中每个数据文件的修改都记录下来。

上面就是xtrabackup的备份过程。接下来是准备(prepare)过程。在这个过程中，xtrabackup使用之前复制的事务日志，对各个数据文件执行灾难恢复(就像MySQL刚启动时要做的一样)。当这个过程结束后，数据库就可以做恢复还原了。

以上的过程在xtrabackup的编译二进制程序中实现。程序innobackupex可以允许我们备份MyISAM表和frm文件从而增加了便捷和功能。Innobackupex会启动xtrabackup，直到xtrabackup复制数据文件后，然后执行FLUSH TABLES WITH READ LOCK来阻止新的写入进来并把MyISAM表数据刷到硬盘上，之后复制MyISAM数据文件，***释放锁。

备份MyISAM和InnoDB表最终会处于一致，在准备(prepare)过程结束后，InnoDB表数据已经前滚到整个备份结束的点，而不是回滚到xtrabackup刚开始时的点。这个时间点与执行FLUSH TABLES WITH READ LOCK的时间点相同，所以MyISAM表数据与InnoDB表数据是同步的。类似Oracle的，InnoDB的prepare过程可以称为recover(恢复)，MyISAM的数据复制过程可以称为restore(还原)。

xtrabackup和innobackupex这两个工具都提供了许多前文没有提到的功能特点。手册上有对各个功能都有详细的介绍。简单介绍下，这些工具提供了如流(streaming)备份，增量(incremental)备份等，通过复制数据文件，复制日志文件和提交日志到数据文件(前滚)实现了各种复合备份方式。

如下图所示：

案例分析：

一、数据库全备

1、创建配置文件

[root@rh64 ~]# cat /tmp/my.cnf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

innodb_data_file_path=ibdata1:12M;ibdata2:10M:autoextend

innodb_log_files_in_group=2

innodb_log_file_size=50331648

2、创建备份目录

[root@rh64 ~]# ls -ld /data/mysql/backup/

drwxrwxrwx. 3 mysql mysql 4096 Oct 15 12:13 /data/mysql/backup/

3、测试

mysql> show databases;

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

| Database |

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

| information_schema |

| mysql |

| performance_schema |

| prod |

| test |

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

5 rows in set (0.06 sec)

mysql> use prod;

Reading table information for completion of table and column names

You can turn off this feature to get a quicker startup with -A

Database changed

mysql> show tables;

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

| Tables_in_prod |

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

| t1 |

| t2 |

| t3 |

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

3 rows in set (0.00 sec)

mysql> select count(*) from t1;

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

| count(*) |

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

| 49152 |

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

1 row in set (0.13 sec)

插入数据：

mysql> insert into t1 select * from t1;

Query OK, 49152 rows affected (0.69 sec)

Records: 49152 Duplicates: 0 Warnings: 0

mysql> commit;

Query OK, 0 rows affected (0.00 sec)

mysql> select count(*) from t1;

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

| count(*) |

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

| 98304 |

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

1 row in set (0.03 sec)

4、创建备份用户并授权

mysql> create user 'bkusr'@'%' identified by 'oracle';

Query OK, 0 rows affected (0.00 sec)

mysql> grant reload,create tablespace,lock tables ,replication client,super on *.* to 'bakusr'@'%';

Query OK, 0 rows affected (0.00 sec

mysql> create user 'bakusr'@localhost identified by 'oracle';

Query OK, 0 rows affected (0.00 sec)

5、进行数据库全备

[root@rh64 ~]# innobackupex --user=bakusr --password='oracle' --socket=/var/lib/mysql/mysql.sock --defaults-file=/tmp/my.cnf /data/mysql/backup/full

　　xtrabackup: Error: --defaults-file must be specified first on the command line

----提示配置文件参数必须放在***位

以root用户备份：

[root@rh64 ~]# innobackupex --defaults-file=/etc/my.cnf --user=root --password='oracle' --socket=/var/lib/mysql/mysql.sock /data/mysql/backup/full
