在centos7.0下安装xtrabackup报错

在centos7.0下安装xtrabackup报错：

# rpm -ivh percona-xtrabackup-24-2.4.2-1.el7.x86_64.rpm

error: Failed dependencies:

        libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.2-1.el7.x86_64

        perl(DBD::mysql) is needed by percona-xtrabackup-24-2.4.2-1.el7.x86_64

解决方法：

 yum -y install perl-DBD-MySQL

 yum -y install libev

如果没有包可在尝试配percona的yum源：

vi /etc/yum.repos.d/Percona.repo


[percona]
name = CentOS $releasever - Percona
baseurl=http://repo.percona.com/centos/$releasever/os/$basearch/
