4：安装Percona XtraBackup包percona-xtrabackup-24
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
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
[root@DB-Server tmp]# rpm -ivh percona-xtrabackup-2.2.12-1.el5.x86_64.rpm
warning: percona-xtrabackup-2.2.12-1.el5.x86_64.rpm: Header V4 DSA signature: NOKEY, key ID cd2efd2a
error: Failed dependencies:
