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：

二、数据库恢复
1、测试
关闭数据库，更改datadir目录
[mysql@rh64 ~]$ service mysql stop
Shutting down MySQL (Percona Server)...[ OK ]
rm: cannot remove `/var/lock/subsys/mysql: Permission denied
[root@rh64 ~]# mv /var/lib/mysql /var/lib/mysql.bak
[root@rh64 ~]# cd /var/lib/mysql.bak
[root@rh64 mysql.bak]# ls
auto.cnf ibdata2 ib_logfile1 mysql prod RPM_UPGRADE_HISTORY test
ibdata1 ib_logfile0 ib_logfile101 performance_schema rh64.pid RPM_UPGRADE_MARKER-LAST
创建新的datadir:
[root@rh64 mysql.bak]# mkdir /var/lib/mysql
数据库恢复：
[root@rh64 backup]# innobackupex --defaults-file=/etc/my.cnf --copy-back --rsync /data/mysql/backup/full

151028 14:41:54 completed OK!
重新授权datadir：
[root@rh64 lib]# ls -ld mysql.bak/
drwxr-xr-x. 6 mysql mysql 4096 Oct 28 14:38 mysql.bak/
[root@rh64 lib]# ls -ld mysql
