安装过程种有很多报错，这里我就不一一解释。

1	wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.3.5/binary/redhat/6/x86_64/percona-xtrabackup-2.3.5-1.el6.x86_64.rpm

 

1	yum install perl-DBD-MySQL perl-Time-HiRes perl-IO-Socket-SSL

 安装epel源，是为了出现 libev.so4的报错。其实就是使用epel源来安装Libev

1 2	rpm -ivh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm yum install libev

 出现这个  libnuma.so.1()(64bit) is needed by依赖

1	yum -y install numactl*
