参见percona官网通过使用yum安装xtrabackup。
https://www.percona.com/doc/percona-xtrabackup/LATEST/installation/yum_repo.html
1、安装percona依赖库：
使用root执行下面的命令
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm
确保安装成功。
2、测试依赖库是否安装成功：
yum list | grep percona
... percona-xtrabackup-20.x86_64 2.0.8-587.rhel5 percona-release-x86_64 percona-xtrabackup-20-debuginfo.x86_64 2.0.8-587.rhel5 percona-release-x86_64 percona-xtrabackup-20-test.x86_64 2.0.8-587.rhel5 percona-release-x86_64 percona-xtrabackup-21.x86_64 2.1.9-746.rhel5 percona-release-x86_64 percona-xtrabackup-21-debuginfo.x86_64 2.1.9-746.rhel5 percona-release-x86_64 percona-xtrabackup-22.x86_64 2.2.13-1.el5 percona-release-x86_64 percona-xtrabackup-22-debuginfo.x86_64 2.2.13-1.el5 percona-release-x86_64 percona-xtrabackup-debuginfo.x86_64 2.3.5-1.el5 percona-release-x86_64 percona-xtrabackup-test.x86_64 2.3.5-1.el5 percona-release-x86_64 percona-xtrabackup-test-21.x86_64 2.1.9-746.rhel5 percona-release-x86_64 percona-xtrabackup-test-22.x86_64 2.2.13-1.el5 percona-release-x86_64 ...
3、安装percona
yum install percona-xtrabackup-24
提示缺少包libev.so.4()(64bit)：
错误：Package: percona-xtrabackup-24-2.4.12-1.el6.x86_64 (percona-release-x86_64)
Requires: libev.so.4()(64bit)
安装之。
4、在http://rpmfind.net/linux/rpm2html/search.php上直接搜索该包libev-4.04-2.el6.x86_64.rpm安装之。
[root@MysqL ~]# rpm -ivh libev-4.04-2.el6.x86_64.rpm warning: libev-4.04-2.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature,key ID 66534c2b: NOKEY Preparing... ########################################### [100%] 1:libev ########################################### [100%]
5、然后在安装xtrabackup包：
