XtraBackup介绍

 

XtraBackup是Percona公司的开源项目,用以实现类似Innodb官方的热备份工具InnoDB
Hot
Backup的功能,它支持在线热备份(备份时不影响数据读写)。到目前为止,最新的版本为Percona
XtraBackup 2.4.7.

 

XtraBackup有很多功能和优点:例如支持全备、增量备份、部分备份;支持压缩备份;备份不影响数据读写、事务等,但是也有缺陷不足:例如不支持脱机备份、不支持直接备份到磁带设备、不支持Cloud
Back,MyISAM的备份也会阻塞。不过这些小瑕疵不影响XtraBackup成为一款流行的MySQL备份工具。另外,请注意XtraBackup只支持Linux平台,不支持Windows平台。

 

下面是XtraBackup的官方文档的介绍资料:

 

Percona XtraBackup is the world’s only open-source, free MySQL hot
backup software that performs non-blocking

backups for InnoDB and XtraDB databases. With Percona XtraBackup, you
can achieve the following benefits:

 

• Backups that complete quickly and reliably

• Uninterrupted transaction processing during backups

• Savings on disk space and network bandwidth

• Automatic backup verification

• Higher uptime due to faster restore time

 

Percona XtraBackup makes MySQL hot backups for all versions of Percona
Server, MySQL, and MariaDB. It performs

streaming, compressed, and incremental MySQL backups.

 

Percona XtraBackup works with MySQL, MariaDB, and Percona Server. It
supports completely non-blocking backups

of InnoDB, XtraDB, and HailDB storage engines. In addition, it can back
up the following storage engines by briefly

pausing writes at the end of the backup: MyISAM, Merge, and Archive,
including partitioned tables, triggers, and

database options.

XtraBackup安装

 

Percona
XtraBackup的安装方式总体来说有下面三种,我们下面简单的介绍一下。然后都具体都练练手。

 

Installing Percona XtraBackup from Repositories (recommended)

Installing Percona XtraBackup from Downloaded rpm or apt Packages

Compiling and Installing from Source Code

 

1:Installing Percona XtraBackup from Repositories

 

Installing Percona XtraBackup on Red Hat
Enterprise Linux and CentOS

 

 

 

下面我测试的环境为CentOS Linux release 7.2.1511 (Core) ,安装Percona
XtraBackup 2.4为例:

 

 

步骤1: Install the Percona repository

 

[[email protected] ~]$ sudo yum install https://www.percona.com/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm

[sudo] password for test: 

/usr/local/bin/aad-login failed: exit code 1

  percona-release.noarch 0:0.1-4                                                

 

Complete!

 

RHEL/Centos
5不支持从远程位置直接安装软件包,因此您需要首先下载软件包,然后用rpm手动安装

 

$ wget http://www.percona.com/downloads/percona-release/redhat/0.1-4/\

percona-release-0.1-4.noarch.rpm

$ rpm -ivh percona-release-0.1-4.noarch.rpm

 

安装完成后,你就能在/etc/yum.repos.d
下看到一个percona-release.repo文件。

 

 

 

步骤2: 测试Repository,确保Percona XtraBackup相关包已经在Repository中。

 

 

[[email protected] ~]$ yum list | grep percona-xtrabackup

步骤3:安装Percona XtraBackup包。

2:Installing Percona XtraBackup from Downloaded rpm or apt Packages

 

 

1:使用yum localinstall package 从本机目录安装软件包

 

 

[[email protected] ~]# wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.4/\

 

> binary/redhat/7/x86_64/percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm

 

 

 

[[email protected] ~]#yum localinstall percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm

 

 

2:原始的rpm安装方式

 

 

 

 这里测试环境,下载的是
Percona-XtraBackup-2.2.12-r8726828-el5-x86_64-bundle.tar安装包。在安装之前最好安装一些其他额外组件,例如perl-DBD-MySQL等。否则你会遇到一些杂七杂八的问题。例如

 

perl(DBD::mysql) is needed by percona-xtrabackup-2.2.12-1.el5.x86_64

 

[[email protected]
tmp]# rpm -ivh percona-xtrabackup-2.2.12-1.el5.x86_64.rpm

3:Compiling and Installing from Source Code

 

Percona
Xtrabackup的源码位于github上,URL链接为
你可以下载,也可以使用git命令下载源码。源码安装的具体过程如下所示:

 

1:如果没有安装git,则需先安装git包

 

 

[[email protected]
~]# sudo yum install git

 

 

2:使用git clone获取相关源码

 

# git clone

 

 

# cd percona-xtrabackup/

# git checkout 2.4

 

3:安装相关依赖包

 

# yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf
\

bison libtool ncurses-devel libgcrypt-devel libev-devel libcurl-devel \

vim-common

 

# cmake -DBUILD_CONFIG=xtrabackup_release -DWITH_MAN_PAGES=OFF &&
make –j4

 

 

如上所示,在使用cmake编译时,遇到了错误,可以用如下方法解决。

 

# mkdir -p /usr/local/boost

# cd /usr/local/boost

# wget

# tar -xvzf boost_1_59_0.tar.gz

# rm boost_1_59_0.tar.gz

 

继续编译,增加参数(红色部分)

 

#cmake -DBUILD_CONFIG=xtrabackup_release \

          -DWITH_MAN_PAGES=OFF \

          -DWITH_BOOST=/usr/local/boost \

          && make -j4

 

# make install

     

# /usr/local/xtrabackup/bin/innobackupex –version

innobackupex version 2.4.7 Linux (x86_64) (revision id: 5b42862)

XtraBackup介绍

 

XtraBackup是Percona公司的开源项目,用以实现类似Innodb官方的热备份工具InnoDB
Hot
Backup的功能,它支持在线热备份(备份时不影响数据读写)。到目前为止,最新的版本为Percona
XtraBackup 2.4.7.

 

XtraBackup有很多功能和优点:例如支持全备、增量备份、部分备份;支持压缩备份;备份不影响数据读写、事务等,但是也有缺陷不足:例如不支持脱机备份、不支持直接备份到磁带设备、不支持Cloud
Back,MyISAM的备份也会阻塞。不过这些小瑕疵不影响XtraBackup成为一款流行的MySQL备份工具。另外,请注意XtraBackup只支持Linux平台,不支持Windows平台。

 

下面是XtraBackup的官方文档的介绍资料:

 

Percona
XtraBackup is the world’s
only open-source, free MySQL hot backup software that performs
non-blocking

backups
for InnoDB and XtraDB databases. With Percona XtraBackup, you can
achieve the following benefits:

 


Backups that complete quickly and reliably


Uninterrupted transaction processing during backups


Savings on disk space and network bandwidth


Automatic backup verification


Higher uptime due to faster restore time

 

Percona
XtraBackup makes MySQL hot backups for all versions of Percona Server,
MySQL, and MariaDB. It performs

streaming,
compressed, and incremental MySQL backups.

 

Percona
XtraBackup works with MySQL, MariaDB, and Percona Server. It supports
completely non-blocking backups

of
InnoDB, XtraDB, and HailDB storage engines. In addition, it can back up
the following storage engines by briefly

pausing
writes at the end of the backup: MyISAM, Merge, and Archive, including
partitioned tables, triggers, and

database
options.

XtraBackup安装

 

Percona
XtraBackup的安装方式总体来说有下面三种,我们下面简单的介绍一下。然后都具体都练练手。

 

Installing
Percona XtraBackup from Repositories (recommended)

Installing
Percona XtraBackup from Downloaded rpm or apt Packages

Compiling
and Installing from Source Code

 

1:Installing
Percona XtraBackup from Repositories

 

Installing
Percona XtraBackup on Red Hat Enterprise Linux and CentOS

 

 

 

下面我测试的环境为CentOS
Linux release 7.2.1511 (Core) ,安装Percona XtraBackup 2.4为例:

 

 

步骤1:
Install the Percona repository

 

[test@mylnx06 ~]$ sudo yum install https://www.percona.com/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm

[sudo] password for test: 

/usr/local/bin/aad-login failed: exit code 1

  Verifying  : percona-release-0.1-4.noarch                                 1/1 

 

Installed:

  percona-release.noarch 0:0.1-4                                                

 

Complete!

 

RHEL/Centos
5不支持从远程位置直接安装软件包,因此您需要首先下载软件包,然后用rpm手动安装

 

$ wget http://www.percona.com/downloads/percona-release/redhat/0.1-4/\

percona-release-0.1-4.noarch.rpm

$ rpm -ivh percona-release-0.1-4.noarch.rpm

 

安装完成后,你就能在/etc/yum.repos.d
下看到一个percona-release.repo文件。

 

 

 

步骤2:
测试Repository,确保Percona XtraBackup相关包已经在Repository中。

 

 

[test@mylnx06 ~]$ yum list | grep percona-xtrabackup

percona-xtrabackup-24.x86_64               2.4.7-2.el7                 @percona-release-x86_64

percona-xtrabackup.x86_64                  2.3.8-1.el7                 percona-release-x86_64

percona-xtrabackup-debuginfo.x86_64        2.3.8-1.el7                 percona-release-x86_64

percona-xtrabackup-test.x86_64             2.3.8-1.el7                 percona-release-x86_64

percona-xtrabackup-test-22.x86_64          2.2.13-1.el7                percona-release-x86_64

percona-xtrabackup-test-24.x86_64          2.4.7-2.el7                 percona-release-x86_64

 

 

 

步骤3:安装Percona
XtraBackup包。

 

 

[test@mylnx06 ~]$ yum install percona-xtrabackup-24
