mysql innobackupex备份实施

 最近用innobackup进行备份测试，我们只备份一个innodb类型的库，数据大小大概50多G，用innobackupex大概用了5个多小时，但是mysqldump只用了大约2个小时，这让我很费解，有哪位知道的同志能够交流下？按理说innobackupex应该快的，还有就是大家在备份时不要放到高峰期，因为innobackupex备份时比较吃系统IO，下面就是我备份脚本，分为全备和增备，使用innobackupex需要安装依赖包：

yum install perl-DBD-MySQL*

一、全备

1、全备脚本

--全备到远程服务器

/data/mysql/bin/innobackupex  --defaults-file=/etc/my.cnf --user=root  --password="*******" --database=report  
--stream=tar /data/backup/fullbackup 2>/data/backup/fullbackup/bak.log |gzip| ssh root@192.168.1.1 "cat - > /data/backup/fullbackup/`date +%F_%H-%M-%S`.tar.gz "

--全量备份到本地

/data/mysql/bin/innobackupex  --defaults-file=/etc/my.cnf --user=root  --password="******" --database=report  
--stream=tar /data/backup/fullbackup 2>/data/backup/fullbackup/bak.log | gzip > /data/backup/fullbackup/`date +%F_%H-%M-%S`.tar.gz

注意事项：1、--defaults-file参数需要放在第一个位置，否则报错提示，通过这个参数，将数据文件（由cnf里的变量datadir指定）拷贝至备份目录下。备份成功后，将在备份目录下创建一个时间戳目录，在该目录下存放备份文件。

              2、--stream=tar表示通过流的方式将文件传送给tar进行归档。

　　　　　3、还有其他的参数请参考官方文档。

2、全备恢复
--解压

tar -izxvf 2015-10-26_18-11-16.tar.gz -C 2015-10-26_18-11-16

注意事项：需要添加-i参数，否则解压出来的文件不全，通过-C指定目标目录
--全量恢复：假设恢复还原到3307端口的库中

恢复分为两步，第一步需要“prepare”，其实就是xtrabackup应用事务日志，对于已经commit的操作进行前滚，对于rollback的操作进行回滚，这个跟crash recovery类似。
     --应用日志：

/data/mysql/bin/innobackupex --apply-log  /data/backup/fullbackup/2015-10-26_18-11-16

   注意：apply-log后备份目录会出现xtrabackup_binlog_pos_innodb，这个文件记录应用到binlog日志的文件和位置。有时可能会有xtrabackup_binlog_info文件，如果做从库，那么以哪个为准呢？

           1 对于纯 InnoDB 操作，备份出来的数据中上述两个文件的内容是一致的
           2 对于 InnoDB 和非事务存储引擎混合操作，xtrabackup_binlog_info 中所示的 position 应该会比 xtrabackup_pos_innodb 所示的数值大。此时应以 xtrabackup_binlog_info 为准；

     --copy文件

#需先关闭mysql服务
/data/mysql/bin/mysqladmin -S /tmp/mysql3307.sock --user=root  --password="*******" shutdown
#删除数据库目录文件和日志
 rm -rf /data/mysql/data2/report ib*
#进行文件同步
rsync -avz report ib* /data/mysql/data2
#最后别忘了修改权限
chown -R mysql:mysql /data/mysql/data2/*

  注意事项：使用--copy-back，要求data目录下面为空，如不为空，会报错如下Original data directory /data/mysql/data2 is not empty!这种适合备份实例下的所有数据库的情况，这时可以清空data目录。但是不适合只备份特定的某些库，由于我们是备份特定report库，所以这里直接用rsync来同步文件。下面的是官方的copy-back供参考：

/data/mysql/bin/innobackupex   --defaults-file=/etc/my_3307.cnf --copy-back  /data/backup/fullbackup/2015-10-26_18-11-16 

到这里，数据库就恢复还原好了，可以重新启动mysql服务，登录mysql查看数据恢复情况。一般来说全备的恢复比较简单。但是每次备份的数据量比较大，时间也长，大家根据实际情况决定备份方式。

二、增备
增量备份：以某个特定的全备为基础，个人理解可以细分两种：一种是每天都以该全备为基础进行增备。另一种是以前一天的增量为基础进行增量。

/data/mysql/bin/innobackupex  --user=root  --password="*******" --database=report 
--incremental --incremental-basedir=/data/backup/fullbackup/2015-10-27_15-27-04 /data/backup/fullbackup

注意事项：--incremental参数指明用增量备份方式；--incremental-basedir参数指定以哪个全备为基础

对于第一种恢复方法：

/data/mysql/bin/innobackupex --apply-log --redo-only /data/backup/fullbackup/2015-10-27_15-27-04
/data/mysql/bin/innobackupex --apply-log /data/backup/fullbackup/2015-10-27_15-27-04 --incremental-dir=/data/backup/fullbackup/2015-10-27_16-28-40

对于第二种恢复方法：

/data/mysql/bin/innobackupex --apply-log --redo-only /data/backup/fullbackup/2015-10-27_14-20-35
/data/mysql/bin/innobackupex --apply-log --redo-only /data/backup/fullbackup/2015-10-27_14-20-37
......redo每一天的增量
/data/mysql/bin/innobackupex --apply-log /data/backup/fullbackup/2015-10-27_14-20-35 --incremental-dir=/data/backup/fullbackup/2015-10-27_14-35-11

注意事项：

对于第一种方式:由于每次都是以全备为基础增量，所以只需恢复全备和最后一次的增量即可。

对于第二种方式：需要按顺序对全备，第一次增备...第N-1次增备进行应用事务日志文件，最后一次的增量不需要，最终日志都应用到全备中了，故最后只需要将全备文件夹中的文件copy到对应data目录即可。

三、从全备中恢复指定的表

其实，我们很多情况下并不需要恢复整个库，更多的是恢复指定的表，如果用mysqldump备份的就非常蛋疼了，我曾经从一个mysqldump备份的70G文件中抽取恢复一张有2000万记录的表，可想而知，这种方式效率有多低下吧，下面我介绍下应用innobackupex全备情况下，如何恢复还原指定表。

使用innobackupex恢复指定表前提条件：

• 源和目标数据库server需要使用独立表空间，即开启InnoDB_File_Per_Table = ON参数
• 目标数据库需要使用mysql5.6及以上版本或者xtradb引擎，源数据库不作限制

【恢复还原】

 1、应用日志，这里需要加上--export参数：

/data/mysql/bin/innobackupex --apply-log --export /data/backup/test

这时，在全备目录下数据库目录中多生成了.cfg和.exp两个文件，如下：

root > ll
-rw-r--r-- 1 root root        490 Nov 11 16:04 users_cdk.cfg
-rw-r--r-- 1 root root      16384 Nov 11 16:04 users_cdk.exp
-rw-rw---- 1 root root       8640 Jul 23 15:57 users_cdk.frm
-rw-rw---- 1 root root      98304 Jul 24 16:07 users_cdk.ibd

2、还原指定的t_user_session表数据：

• 需要在目标库中手工建好与源数据库一致的表结构：（省）
• discard t_user_session表空间：

mysql> ALTER TABLE t_user_session  DISCARD TABLESPACE;
Query OK, 0 rows affected (0.01 sec)

• 从备份目录复制.cfg .ibd文件到目标服务器数据库目录

[root@1.1.1.1]# cp t_user_session.ibd t_user_session.cfg /data/mysql/data/test/
[root@1.1.1.1]# 

• 进入到MySQL之后Import表空间

mysql> ALTER TABLE t_user_session import TABLESPACE;
ERROR 1815 (HY000): Internal error: Cannot reset LSNs in table '"test"."t_user_session"' : Tablespace not found
--该错误是由于数据文件所属权限问题，需要改为mysql用户，比如：
-rw-r--r--1 root  root        719 Nov 11 16:59 t_user_session.cfg
-rw-rw----1 mysql mysql      8792 Nov 11 16:58 t_user_session.frm
-rw-r-----1 root  root  813694976 Nov 11 16:59 t_user_session.ibd
--再次导入表空间
mysql> ALTER TABLE t_user_session import TABLESPACE;
Query OK, 0 rows affected (1 min 22.51 sec)

这时数据就还原完成了，比mysqldump抽取大文件快多了吧。

mysql> select *  from t_user_session limit 10;

【注意点】:

• 在复制备份文件的时候一定要复制后缀cfg文件,否则在Import的时候就会报Warning.例如如下的信息:

+---------+------+-------------------------------------------------------------------------------------------------------------------------------------------+
| Warning | 1810 | InnoDB: IO Read error: (2, No such file or directory) Error opening './test/t.cfg', will attempt to import without schema verification    |
+---------+------+-------------------------------------------------------------------------------------------------------------------------------------------+
cfg文件的用处主要是在MySQL5.6执行"Flush Table xxx Export;"之后使.ibd文件保持一致性,同时这个文件会生成一个.cfg文件,在做Import的时候会对导入过程进行校验,但是在 MySQL5.6.8版本之后也不是必须要有.cfg文件.如果真没有,在导入的时候有可能就会报出上面的错误,所以为了安全还是复制它.

• 如果表有外键在Discard的时候执行如下命令:set FOREIGN_KEY_CHECKS=0; 在Import表之后执行以下命令恢复外键检查：set FOREIGN_KEY_CHECKS=1;
• 从备份目录复制.cfg .ibd文件到目标服务器数据库目录后，别忘了查看文件所属权限，否则报如下错误：ERROR 1815 (HY000): Internal error: Cannot reset LSNs in table '"test"."t_user_session"' : Tablespace not found

四、相关备份脚本

下面提供两个shell写的备份脚本，是转网友的，个人觉得写的挺全的，给大家参考：

1、全备shell脚本

#!/bin/bash
user='root'
passwd='root'
database=test
my_config='/etc/my.cnf'
backup_dir='/data/backup/fullbackup'
log=$database-$(date +%Y%m%d%H%M).log
str=$database-$(date +%Y%m%d%H%M).tar.gz
 
echo "Start to backup at $(date +%Y%m%d%H%M)" >> /data/backup/fullbackup/$log
if [ ! -d "$backup_dir" ];then
mkdir -p $backup_dir
fi
/data/mysql/bin/innobackupex --defaults-file=$my_config --user=$user --password=$passwd --database=$database --stream=tar $backup_dir 2>$backup_dir/$log | gzip >$backup_dir/

$str
if [ $? -eq 0 ];then
echo "Backup is finish! at $(date +%Y%m%d%H%M)"  >> /data/backup/fullbackup/$log
exit 0
else
echo "Backup is Fail! at $(date +%Y%m%d%H%M)"  >> /data/backup/fullbackup/$log
exit 1
fi 

2、全备加增备
