Xtrabackup是由percona开发的一个开源软件，它是innodb热备工具ibbackup（收费的商业软件）的一个开源替代品。Xtrabackup由个部分组成:xtrabackup和innobackupex，其中xtrabackup工具用于备份innodb和 xtraDB引擎的表；而innobackupex工具用于备份myisam和innodb引擎的表，本文将介绍如何用innobackupex工具做全量和增量备份。

安装

声明：以下操作最好以MySQL用户执行。

首先，通过wget下载源码tar包：

wget http://www.percona.com/redir/downloads/XtraBackup/LATEST/source/percona-xtrabackup-2.1.5.tar.gz
安装依赖包：

yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bzr bison libtool ncurses-devel zlib-devel

解压缩tar：

tar -zxvf percona-xtrabackup-2.1.5.tar.gz

cd percona-xtrabackup-2.1.5

utils/build.sh脚本会根据指定的引擎版本，自动解压缩适当的MySQL源码包并进行编译，这是最简单的安装方式。当你在命令行下不带任何参数执行该脚本时，出现如下提示：

[mysql@epay100 ~/software/percona-xtrabackup-2.1.5 ]$ ./utils/build.sh

Build an xtrabackup binary against the specified InnoDB flavor.

Usage: build.sh CODEBASE

where CODEBASE can be one of the following values or aliases:

innodb51 | plugin build against InnoDB plugin in MySQL 5.1

innodb55 | 5.5 build against InnoDB in MySQL 5.5

innodb56 | 5.6,xtradb56, build against InnoDB in MySQL 5.6

| mariadb100

xtradb51 | xtradb,mariadb51 build against Percona Server with XtraDB 5.1

| mariadb52,mariadb53

xtradb55 | galera55,mariadb55 build against Percona Server with XtraDB 5.5

根据上面提示和你使用的存储引擎及版本，选择相应的参数即可。因为我用的是MySQL 5.6，所以执行如下语句安装：

./utils/build.sh innodb56

以上语句执行成功后，表示安装完成。最后，把生成的二进制文件拷贝到一个自定义目录下（本例中为/home/mysql/admin/bin/percona-xtrabackup-2.1.5），并把该目录放到环境变量PATH中。

cp ./innobackupex /home/mysql/admin/bin/percona-xtrabackup-2.1.5

cp ./src/xtrabackup_56 ./src/xbstream /home/mysql/admin/bin/percona-xtrabackup-2.1.5

这里我是把他直接cp到/usr/bin目录下

我这里的MySQL版本是5.6.23
我这里用的xtrabackup的版本是2.1.9

安装的过程遇到的问题
1：./utils/build.sh: line 173: patch: command not found
解决方法是：yum -y install patch
然后再次执行
./utils/build.sh innodb56

这里我们创建一个普通的用户来进行热备
用户拥有的权限有
SELECT, RELOAD, SHOW DATABASES, LOCK TABLES
权限列表

1.Select 读取

2.SHOW DATABASES 允许访问完整的数据库列表

4. LOCK TABLES 允许锁定表

5.RELOAD 允许载入和刷新服务器缓存

这里我采取另外一种安装方法：

安装
*****************************************************************

----1.编译安装percona-xtrabackup

yum -y install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bzr bison libtool  zlib-devel libgcrypt-devel libcurl-devel  crypt*  libgcrypt* python-sphinx openssl imake libxml2-devel expat-devel ncurses5-devel ncurses-devle vim-common libgpg-error-devel libidn-devel

NOTE:2.2.16 需要python-sphinx openssl两个依赖包.

---2.安装相关插件

yum -y install perl-DBI
yum -y install perl-DBD-MySQL
yum -y install  perl-Time-HiRes
yum -y install perl-IO-Socket-SSL

wget  http://www.percona.com/downloads/percona-toolkit/2.2.16/RPM/percona-toolkit-2.2.16-1.noarch.rpm 
rpm -ivh percona-toolkit-2.2.16-1.noarch.rpm

---3.安装xtrabackup

wget http://www.percona.com/downloads/XtraBackup/XtraBackup-2.2.11/source/tarball/percona-xtrabackup-2.2.11.tar.gz 
mkdir -p /usr/local/xtrabackup

tar xvzf percona-xtrabackup-2.3.3.tar.gz -C /usr/local/xtrabackup/ && cd /usr/local/xtrabackup/percona-xtrabackup-2.3.3

chown -R  mysql:mysql /usr/local/xtrabackup

cd /usr/local/xtrabackup/percona-xtrabackup-2.3.3

cmake -DBUILD_CONFIG=xtrabackup_release -DWITH_MAN_PAGES=OFF && make -j4 --DINSTALL_LAYOUT=/usr/local/xtrabackup
make
make install

/**************编译安装相关参数

cmake . -LH  --查看cmake支持的mysql相关参数

shell> cmake . -L   # overview
shell> cmake . -LH  # overview with help text
shell> cmake . -LAH # all params with help text
shell> cmake .     # interactive display

******************

make

********************make可能遇到的错误

1.重新编译时，需要清除旧的对象文件和缓存信息

Could not import extension sphinx.ext.extlinks (exception: No module named extlinks)

make clean

rm -f  CMakeCache.txt

2.LIBEV_INCLUDE_DIRS

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
