  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有两个主要的工具:xtrabackup、innobackupex

  (1)xtrabackup只能备份InnoDB和XtraDB两种数据表,而不能备份MyISAM数据表

  (2)innobackupex-1.5.1则封装了xtrabackup,是一个脚本封装,所以能同时备份处理innodb和myisam,但在处理myisam时需要加一个读锁

  安装XtraBackup,首先要安装MySQL

  1、查看MySQL版本

  [root@rh64 ~]# service mysql start

  Starting MySQL (Percona Server)...[ OK ]

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

  Enter password:

  Welcome to the MySQL monitor. Commands end with ; or \g.

  Your MySQL connection id is 1

  2、安装配置

  在/etc/my.cnf文件要配置数据所存储的目录

  [root@rh64 XtraBackup]# cat /etc/my.cnf |grep datadir

  datadir=/var/lib/mysql

  3、下载安装

  

  安装:

  [root@rh64 XtraBackup]# ls -l

  Libraries have been installed in:

  If you ever happen to want to link against installed libraries

  in a given directory, LIBDIR, you must either use libtool, and

  specify the full pathname of the library, or use the `-LLIBDIR'

  flag during linking and do at least one of the following:

  - add LIBDIR to the `LD_LIBRARY_PATH' environment variable

  during execution

  - add LIBDIR to the `LD_RUN_PATH' environment variable

  during linking

  - use the `-Wl,-rpath -Wl,LIBDIR' linker flag

  - have your system administrator add LIBDIR to `/etc/ld.so.conf'

  See any operating system documentation about shared libraries for

  more information, such as the ld(1) and ld.so(8) manual pages.

  INNOBACKUPEX(1) Percona XtraBackup INNOBACKUPEX(1)

  NAME

  innobackupex - innobackupex Documentation

  The innobackupex tool is a Perl script that acts as a wrapper for the xtrabackup C program. It

  is a patched version of the innobackup Perl script that Oracle distributes with the InnoDB Hot

  Backup tool. It enables more functionality by integrating xtrabackup and other functions such as

  file copying and streaming, and adds some convenience. It lets you perform point-in-time backups

  of InnoDB / XtraDB tables together with the schema definitions, MyISAM tables, and other por-

  tions of the server.

  This manual section explains how to use innobackupex in detail.

  PREREQUISITES

  Connection and Privileges Needed

  Percona XtraBackup needs to be able to connect to the database server and perform operations on

  the server and the datadir when creating a backup, when preparing in some scenarios and when

  restoring it. In order to do so, there are privileges and permission requirements on its execu-

  tion that must be fulfilled.

  Privileges refers to the operations that a system user is permitted to do in the database

  server. They are set at the database server and only apply to users in the database server.

  Permissions are those which permits a user to perform operations on the system, like reading,

  writing or executing on a certain directory or start/stop a system service. They are set at a

  system level and only apply to system users.

  Whether xtrabackup or innobackupex is used, there are two actors involved: the user invoking the

  program - a system user - and the user performing action in the database server - a database

  user. Note that these are different users in different places, even tough they may have the same

  username.

  All the invocations of innobackupex and xtrabackup in this documentation assumes that the system

  user has the appropriate permissions and you are providing the relevant options for connecting

  the database server - besides the options for the action to be performed - and the database user

  has adequate privileges.

  Connecting to the server

  The database user used to connect to the server and its password are specified by the --user and

  --password option,

  $ innobackupex --user=DBUSER --password=SECRET /path/to/backup/dir/

  $ innobackupex --user=LUKE --password=US3TH3F0RC3 --stream=tar ./ | bzip2 -

  $ xtrabackup --user=DVADER --password=14MY0URF4TH3R --backup --target-dir=/data/bkps/

  ----至此,XtraBackup安装完成!!!
