centos下使用yum 安装percona xtrabackup

配置percona的yum仓库 
一、先安装依赖：

yum install perl-DBIyum install perl-DBD-MySQLyum install perl-Time-HiResyum install perl-IO-Socket-SSL12345671234567

二、配置yum源、 
方法1、自动安装percona的yum仓库(以下分别为x86_64和i386平台)

#rpm -ivh http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm#rpm -ivh http://www.percona.com/redir/downloads/percona-release/percona-release-0.0-1.i386.rpm1212

方法2、手动yum仓库

创建文件/etc/yum.repos.d/Percona.repo内容如下:

[percona]
name = CentOS $releasever - Perconabaseurl=http://repo.percona.com/centos/$releasever/os/$basearch/enabled = 1gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-percona
gpgcheck = 112345671234567

获取和保存key

#wget http://www.percona.com/redir/downloads/percona-release/RPM-GPG-KEY-percona#cp RPM-GPG-KEY-percona /etc/pki/rpm-gpg/RPM-GPG-KEY-percona123123

安装 percona xtrabackup
