篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了MySQL 採用Xtrabackup对数据库进行全库备份相关的知识,希望对你有一定的参考价值。
1,xtrabackup简单介绍
关于数据库备份以及备份工具。參考:http://blog.itpub.net/26230597/viewspace-1460065/,这里来介绍xtrabackup已经怎样使用xtrabackup进行对数据库的全备份已经恢复。
2,xtrabackup下载
下载地址为:http://www.percona.com/downloads/XtraBackup/
Chorm浏览器以下。在“DOWNLOADPERCONA XTRABACKUP”以下,选择版本号号以及os版本号。有的浏览器打不开,可能会出现“No files found with current filters.”,那么就须要换个浏览器比方chrome就能够打开了。例如以下图1.png所看到的:
也能够直接在linux以下是用wget的方式下载:
wget http://www.percona.com/downloads/XtraBackup/XtraBackup-2.2.9/binary/tarball/percona-xtrabackup-2.2.9-5067-Linux-x86_64.tar.gz
3,xtrabackup安装
3.1配置datadir
先check下是否已经配置datadir,检查是否有mysql服务。有的话就在my.cnf配置文件里面设置datadir
[[email protected] ~]# more /etc/my.cnf |grepdatadir
[[email protected] ~]#
Ok,看到没有配置datadir,去my.cnf里面配置
vim my.cnf
datadir = /home/data/mysql/data
再check下:
[[email protected] ~]# more /etc/my.cnf |grepdatadir
datadir = /home/data/mysql/data
[[email protected] ~]#
[[email protected] ~]#
3.2解压
tar -xvfpercona-xtrabackup-2.2.9-5067-Linux-x86_64.tar.gz
3.3 copy到/usr/bin/
cp./percona-xtrabackup-2.2.9-Linux-x86_64/bin/innobackupex /usr/bin/innobackupex
cp./percona-xtrabackup-2.2.9-Linux-x86_64/bin/xtrabackup /usr/bin/xtrabackup
cp./percona-xtrabackup-2.2.9-Linux-x86_64/bin/xbcrypt /usr/bin/xbcrypt
cp ./percona-xtrabackup-2.2.9-Linux-x86_64/bin/xbstream/usr/bin/xbstream
PS:新版本号已经没有了innobackupex-1.5.1这个小插件了。
3.4 查看xtrabackup是否可用
[[email protected] ~]# innobackupex --help |more
Options:
--apply-log
Prepare a backup in BACKUP-DIR by applying the transaction log file
named "xtrabackup_logfile" located in the same directory.Also,
create new transaction logs. The InnoDB configuration is read from
the file "backup-my.cnf".
--backup-locks
This option controls if backup locks should be used instead of FLUSH
TABLES WITH READ LOCK on the backup stage. The option has no effect
when backup locks are not supported by the server. This option is
enabled by default, disable with --no-backup-locks.
3.5 源代码方式安装
參考:http://www.percona.com/doc/percona-xtrabackup/2.2/installation/compiling_xtrabackup.html
4,二大工具组件
xtrabackup:支持innodb存储引擎表。xtradb存储引擎表
innobackupex:支持innodb存储引擎表、xtradb存储引擎表、myisam存储引擎表。
5,一些重要參数
--defaults-file
同xtrabackup的--defaults-file參数
--apply-log
对xtrabackup的--prepare參数的封装
--copy-back
做数据恢复时将备份数据文件复制到MySQL服务器的datadir ;
--remote-host=HOSTNAME
通过ssh将备份数据存储到进程服务器上;
--stream=[tar]
备份文件输出格式, tar时使用tar4ibd , 该文件可在XtarBackup binary文件里获得.假设备份时有指定--stream=tar, 则tar4ibd文件所处文件夹一定要在$PATH中(因为使用的是tar4ibd去压缩, 在XtraBackup的binary包中可获得该文件)。
在使用參数stream=tar备份的时候,你的xtrabackup_logfile可能会暂时放在/tmp文件夹下。假设你备份的时候并发写入较大的话 xtrabackup_logfile可能会非常大(5G+)。非常可能会撑满你的/tmp文件夹。能够通过參数--tmpdir指定文件夹来解决问题。
--tmpdir=DIRECTORY
当有指定--remote-host or --stream时, 事务日志暂时存储的文件夹, 默认採用MySQL配置文件里所指定的暂时文件夹tmpdir
--redo-only--apply-log组,
强制备份日志时仅仅redo ,跳过rollback。这在做增量备份时非常必要。
--use-memory=#
该參数在prepare的时候使用,控制prepare时innodb实例使用的内存量,用来代替my.cnf中的buffer_pool_size值,假设你是独立服务器,并且内存足够大的话。为了加快备份恢复的效率。你能够调大--use-memory这个參数值
--throttle=IOS
同xtrabackup的--throttle參数
--sleep=是给ibbackup使用的,指定每备份1M数据,过程停止拷贝多少毫秒。也是为了在备份时尽量减小对正常业务的影响,详细能够查看ibbackup的手冊。
--compress[=LEVEL]
对备份数据迚行压缩,仅支持ibbackup,xtrabackup还没有实现。
--include=REGEXP
对 xtrabackup參数--tables的封装,也支持ibbackup。备份包括的库表。比如:--include="test.*",意思是要备份 test库中全部的表。假设须要全备份。则省略这个參数。假设须要备份test库下的2个表:test1和test2,则写成:--include="test.test1|test.test2"。
也能够使用通配符,如:--include="test.test*"。
--databases=LIST
列出须要备份的databases。假设没有指定该參数。全部包括MyISAM和InnoDB表的database都会被备份。
--uncompress
解压备份的数据文件,支持ibbackup,xtrabackup还没有实现该功能。
--slave-info
备份从库, 加上--slave-info备份文件夹下会多生成一个xtrabackup_slave_info 文件, 这里会保存主日志文件以及偏移, 文件内容相似于:CHANGE MASTER TO MASTER_LOG_FILE=‘‘, MASTER_LOG_POS=0
--socket=SOCKET
指定mysql.sock所在位置,以便备份进程登录mysql.
--safe-slave-backup
则会暂停Slave的SQL线程,等待到没有打开的暂时表的时候開始备份.备份结束后SQL线程会自己主动启动,这样就能够确保一致性的复制状态.
6,xtrabackup全备份
6.1 全备份
仅仅备份不压缩:
xtrabackup --defaults-file=/etc/my.cnf--user=root --password="" --port=3306 --backup--target-dir=/data/backups/mysql/$(date +%Y%m%d)/
备份压缩:
xtrabackup --defaults-file=/etc/my.cnf--user=root --password="" --port=3306 --backup --socket=/usr/local/mysql/mysql.sock--stream=tar --target-dir=/data/backups/mysql/$(date +%Y%m%d)/ |gzip >alldbfullbackup.tar.gz
參考:http://www.percona.com/doc/percona-xtrabackup/2.2/howtos/recipes_ibkx_compressed.html
备份步骤例如以下所看到的:
[[email protected] mysql]# xtrabackup--defaults-file=/etc/my.cnf --user=root --password="" --port=3306--backup --socket=/usr/local/mysql/mysql.sock --stream=tar--target-dir=/data/backups/mysql/$(date +%Y%m%d)/ |gzip > alldbfullbackup.tar.gz
xtrabackup version 2.2.9 based on MySQLserver 5.6.22 Linux (x86_64) (revision id: )
xtrabackup: uses posix_fadvise().
xtrabackup: cd to /home/data/mysql/data
xtrabackup: open files limit requested 0,set to 1024

xtrabackup: innodb_data_home_dir = ./
xtrabackup: innodb_data_file_path =IBdata1:128M;IBdata2:128M:autoextend
xtrabackup: innodb_log_group_home_dir = ./
xtrabackup: innodb_log_files_in_group = 3
xtrabackup: innodb_log_file_size = 67108864

[[email protected] mysql]#
备份结束后,能够看到例如以下结果,备份文件夹为null,都压缩到了alldbfullbackup.tar.gz备份压缩包里面。例如以下所看到的:
[[email protected] mysql]# du -sh *
4.0K 20150318
5.1M alldbfullbackup.tar.gz
[[email protected] mysql]#
PS1:能够用gzip边备份边压缩,只是推荐是备份完了之后对整个备份文件夹进行压缩。
6.2 全量恢复
先删除測试表数据:
mysql> select * from t1;
+---+----+
| a | b |
+---+----+
| 5 | aa |
+---+----+
1 row in set (0.03 sec)
mysql> delete from t1;
Query OK, 1 row affected (0.02 sec)
mysql> select * from t1;
Empty set (0.00 sec)
mysql> exit
Bye
进行恢复
xtrabackup --defaults-file=/etc/my.cnf--prepare --target-dir=/data/backups/mysql/20150318
停止msyql数据库
service mysqld5612 stop
复制已经恢复好的文件到mysql数据文件夹并且赋予mysql账号运行权限
cd /data/backups/mysql/20150318
rsync -rvt --exclude‘xtrabackup_checkpoints‘ --exclude ‘xtrabackup_logfile‘ ./ /home/data/mysql/data
chown -R mysql:mysql /home/data/mysql/data
启动mysql数据库
service mysqld5612 start
恢复完成,check表t1数据,数据恢复回来了:
mysql> use test;
Database changed
mysql> select * from t1;
+---+----+
| a | b |
+---+----+
| 5 | aa |
+---+----+
1 row in set (0.09 sec)
mysql>
PS2: xtrabackup仅仅备份InnoDB数据文件,表结构是不备份的,所以恢复的时候,你必须有相应表结构文件(.frm)。例如以下所看到的。仅仅备份了*.ibd文件:
[[email protected] 20150318]# ll
总用量 262168
