解决方法：没有装 dbi和dbd；也可能是没有指定–user和–password以及权限问题
则按如下步骤进行操作：
Percona Toolkit 的安装：
1:下载percona toolkit的包：（可以是源码包，或者RPM）
访问：http://www.percona.com/software/percona-toolkit/ 下载最新稳定的版本。也可以如下命令行的方式下载最新版本。
wget percona.com/get/percona-toolkit.tar.gz
wget percona.com/get/percona-toolkit.rpm
2：安装于Perl相关的模块
yum install perl-DBI
yum install perl-DBD-MySQL
yum install perl-Time-HiRes
yum install perl-IO-Socket-SSL
3: 安装Percona Toolkit
安装之前需要安装perl-TermReadKey，否则会报错：
error: Failed dependencies:
perl(Term::ReadKey) is needed by percona-toolkit-2.2.17-1.noarch
下载该包：wget http://pkgs.repoforge.org/perl-TermReadKey/perl-TermReadKey-2.30-1.el5.rf.x86_64.rpm
安装该包：rpm -ivh perl-TermReadKey-2.30-1.el5.rf.x86_64.rpm
安装成功后则可以继续安装percona-toolkit
rpm -Uvh percona-toolkit-2.2.1-2.noarch.rpm

- 参考文档
- XtraBackup X--backup
- http://www.cnblogs.com/Amaranthus/archive/2014/08/19/3922570.html

- Xtrabackup是一个对InnoDB做数据备份的工具，支持在线热备份,备份过程不锁表，不受时间限制，不影响用户使用。
- 每日备份只产生少量数据，远程备份传输更方便。同时节省空间。
- 生产环境要求
- 1. /etc/my.cnf中 需要设置datadir default_table_type = InnoDB
- 2.MySQL InnoDB在5.1这个版本不支持。可以使用Percona XtraBackup 2，或升级到InnoDB Plugin
- 1．命令安装：
- yum install -y gnupg
- rpm -Uhv http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm
- yum install -y percona-xtrabackup
- [root@aliyun-112 ~]# xtrabackup -v
- xtrabackup version 2.3.3 based on MySQL server 5.6.24 Linux (x86_64) (revision id: 525ca7d)
- 2．命令功能：
- 对InnoDB做数据备份的工具，支持在线热备份
- 3．命令参数：
- --database=sundong 单独对sundong数据库做备份 ，若是不添加此参数那就那就是对全库做备份
- --stream =tar 打包格式 目前只支持 tar and xbstream
- 2>/var/backups/sundong.log 输出信息写入日志中
- 1> /var/backups/sundong.tar.gz 打包压缩存储到该文件中
- --incremental-dir=/var/backups/plus/ 增量备份目录
- --copy-back选项的命令从备份目录拷贝数据,索引,日志到my.cnf文 件里规定的初始位置
- --apply-log选项的命令是准备在一个备份上启动mysql服务
- --port=PORT
- 4．命令实例：
- 备份并打包压缩
- innobackupex --defaults-file=/home/DB/mysql/my.cnf --user=root --password=sundong@123 --database=sundong --stream=tar /var/backups/ 2>/var/backups/sundong.log | gzip 1> /var/backups/sundong.tar.gz
- 此处可以写个脚本做备份(backup.sh)
- [root@wh-cnc-51 backups]# cat backup.sh
- #!/bin/sh
- echo "begin..."`date`
- log=sundong_`date +%F`.log
- str=sundong_`date +%F`.tar.gz
- innobackupex --defaults-file=/home/DB/mysql/my.cnf --user=root --password=sundong@123 --database=sundong --stream=tar /var/backups/ 2>/var/backups/$log | gzip 1> /var/backups/$str
- echo "completed OK..."`date
- [root@wh-cnc-51 backups]# sh -x backup.sh
- ++ date
- + echo begin...Mon Jan 4 15:05:08 CST 2016
- begin...Mon Jan 4 15:05:08 CST 2016
- ++ date +%F
- + log=sundong_2016-01-04.log
- ++ date +%F
- + str=sundong_2016-01-04.tar.gz
- + gzip
- + innobackupex --defaults-file=/home/DB/mysql/my.cnf --user=root --password=sundong@123 --database=sundong --stream=tar /var/backups/
- ++ date
- + echo 'completed OK...Mon' Jan 4 15:05:11 CST 2016
- completed OK...Mon Jan 4 15:05:11 CST 2016
- [root@wh-cnc-51 backups]# ll
