mysql备份之Xtrabackup

Xtrabackup是一个对InnoDB,做数据备份的工具，支持在线热备份（备份时不影响数据读写），是商业备份工具InnoDB Hotbackup的一个很好的替代品。

Xtrabackup中包含两个工具：

    * xtrabackup - 用于热备份innodb, xtradb表的工具，不能备份其他表。
    * innobackupex - 对xtrabackup封装的perl脚本，提供了myisam表备份的能力。

Xtrabackup可以做什么

    * 在线(热)备份整个库的InnoDB, XtraDB表
    * 在xtrabackup的上一次整库备份基础上做增量备份（innodb only）
    * 以流的形式产生备份，可以直接保存到远程机器上（本机硬盘空间不足时很有用）

Xtrabackup如何工作的

    * xtrabackup - 具体原理有待研究。。。
    * innobackupex整库备份
         1. 调用xtrabackup对innodb表空间文件（这一瞬间的映像Time1）备份，而在这个innodb表备份期间数据库是不加锁的，外部可以继续往库里增减数据（这才能叫热备份）。而在Time1和Time2这两个时间点之间的改动由一个线程不断地扫innodb log获得(ChangeSet1)。
         2. 锁所有库。
         3. 以直接拷贝的方式备份frm,MYD,MYI,MRG,TRG,TRN,opt格式的文件。
         4. 步骤3中的数据备份完毕时(Time2)，停止扫innodb log的线程，把ChangeSet1的数据拷贝到备份中。
         5. 解锁所有库。
         6. 终止挂起，备份完毕。

注意要点

    * 根据innobackupex的原理可知它不是真正的热备份，MyISAM表越少越小就越有利。要利用Xtrabackup的好处就尽量用innodb表。
    * 还原备份前关闭mysql服务；还原备份后检查数据文件权限是否正确。
    * 性能：备份一个数据目录总大小5.6G，其中ibdata 2G，总时间4分钟，锁表时间2.5分钟。如果用mysqldump做这个库的备份锁表时间是5-8倍。




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，并从事务日志复制最新的修改。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，最后释放锁。

       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第一位

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

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

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 14:41:53 [01]        ...done
151028 14:41:54 completed OK!

重新授权datadir：
[root@rh64 lib]# ls -ld mysql.bak/

[root@rh64 lib]# chown -R mysql.mysql mysql

验证数据恢复：
[root@rh64 lib]# service mysql start

[root@rh64 lib]# mysql -u root -p

---至此，数据恢复成功！！！

在MySQL中进行增量备份时，首先要进行一次全量备份，第一次增量备份是基于全备的，之后的增量备份是基于上一次的增量备份。

备份案例：
一、建立增量备份
1、构建测试环境：
[root@rh64 full]# service mysql start
Starting MySQL (Percona Server)[  OK  ]
[root@rh64 full]# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql> use prod;

You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select count(*) from t1;
+----------+
| count(*) |
+----------+
|    98304 |
+----------+
1 row in set (0.12 sec)

对数据库做一次全备：
【root@rh64 ~]# innobackupex --defaults-file=/etc/my.cnf --user=bakusr --password='oracle'  --socket=/var/lib/mysql/mysql.sock  /data/mysql/backup/full  --no-timestamp
2、插入新的数据，做增量备份
mysql> insert into t1 select * from t1 order by 1 limit 10000;
Query OK, 10000 rows affected (0.46 sec)
Records: 10000  Duplicates: 0  Warnings: 0
mysql> commit;
Query OK, 0 rows affected (0.00 sec)
mysql>  select count(*) from t1;
+----------+
| count(*) |
+----------+
|   108304 |
+----------+
1 row in set (0.03 sec)

第一次增量备份：
[root@rh64 full]# innobackupex --defaults-file=/tmp/my.cnf --user=bakusr --password='oracle'  --socket=/var/lib/mysql/mysql.sock --incremental-basedir=/data/mysql/backup/full --incremental /data/mysql/backup/inc_1 --no-timestamp --parallel=2

二、通过备份恢复数据

增量备份的恢复大体分为三个步骤：
1、恢复基础备份（全备）
2、恢复增量备份到基础备份（开始恢复的增量备份要添加--redo-only参数，到最后一次增量备份去掉--redo-only参数）
3、对整体基础备份进行恢复，回滚那些未提交的数据
1、测试环境

数据被误删除：
mysql> truncate table t1;
Query OK, 0 rows affected (0.60 sec)

mysql> select count(*) from t1;
+----------+
| count(*) |
+----------+
|        0 |
+----------+
1 row in set (0.00 sec)


2、数据恢复：

3、把恢复完的备份数据拷贝到数据库数据存储的目录下：
1）关闭数据库
[root@rh64 inc_2]# mysqladmin shutdown -u root -p
Enter password: 
[root@rh64 inc_2]# netstat -an |grep :3306
[root@rh64 inc_2]# mysqladmin status
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!

建立新的数据库存储目录：
[root@rh64 inc_2]# mv mysql  mysql.old
[root@rh64 inc_2]# mkdir -p  /var/lib/mysql
查看最近的备份：
[root@rh64 full]# ls -lt
total 122928

  • 从c面向对象的实现理解c++的对象（二） jimmee C++面向对象虚函数
    1. 类就可以看作一个struct，类的方法，可以理解为通过函数指针的方式实现的，类对象分配内存时，只分配成员变量的，函数指针并不需要分配额外的内存保存地址。 2. c++中类的构造函数，就是进行内存分配(malloc)，调用构造函数 3. c++中类的析构函数，就时回收内存(free) 4. c++是基于栈和全局数据分配内存的，如果是一个方法内创建的对象，就直接在栈上分配内存了。 专门在

  • 最具争议的10个Java话题 tomcat_oracle java
    1、Java8已经到来。什么！？ Java8 支持lambda。哇哦，RIP Scala！ 　　随着Java8 的发布，出现很多关于新发布的Java8是否有潜力干掉Scala的争论，最终的结论是远远没有那么简单。Java8可能已经在Scala的lambda的包围中突围，但Java并非是函数式编程王位的真正觊觎者。 　 　2、Java 9 即将到来 　　 Oracle早在8月份就发布
  • zoj 3826 Hierarchical Notation(模拟) 阿尔萨斯 rar
    题目链接：zoj 3826 Hierarchical Notation 题目大意：给定一些结构体，结构体有value值和key值，Q次询问，输出每个key值对应的value值。 解题思路：思路很简单，写个类词法的递归函数，每次将key值映射成一个hash值，用map映射每个key的value起始终止位置，预处理完了查询就很简单了。 这题是最后10分钟出的，因为没有考虑value为{}的情
