1.安装依赖包

如果yum不能直接安装，可以先把rpm文件下载下来：

　  wget http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm

　　yum -y install percona-release-0.1-4.noarch.rpm

2、测试依赖库是否安装成功(可能有点慢)：

　　yum list | grep percona
　　看到以下内容的输出即可确认安装成功：

 

 3、安装percona，安装是如果有什么依赖，先安装即可；

安装：yum -y install percona-xtrabackup-24-2.4.9-1.el7.x86_64.rpm

4、查看：rpm -ql percona-xtrabackup-24或者xtrabackup --version
