centos7.2上安装MySQL的备份工具xtrabackup，建议挂载镜像，配置YUM源，使用yum进行安装来解决包依赖关系;

除非使用编译安装，不要再使用rpm -ivh来安装xtrabackup了，包依赖关系解决起来累死人，尤其是操作系统是最小化安装

的那种。

1、配置yum源

--获取rpm包

rpm -ivh http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm

--yum仓库

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

enabled = 1

gpgkey = file:///mnt/pki/rpm-gpg/RPM-GPG-KEY-percona

gpgcheck = 1

--获取key-percona

wget http://www.percona.com/redir/downloads/percona-release/RPM-GPG-KEY-percona

cp RPM-GPG-KEY-percona /mnt/pki/rpm-gpg/RPM-GPG-KEY-percona

2、配置好yum源之后，首先安装xtrabackup运行环境必须的perl

[root@idc-srm-mysql-db xtrabackup]# yum -y install perl

Loaded plugins: fastestmirror, langpacks

6、查看xtrabackup版本

[root@idc-srm-mysql-db xtrabackup]# xtrabackup --version

xtrabackup version 2.3.6 based on MySQL server 5.6.24 Linux (x86_64) (revision id: )

[root@idc-srm-mysql-db xtrabackup]#

到此xtrabackup安装完成，可以使用了，如果是rpm安装会非常麻烦，一个个rpm包依赖，找起来困难，安装起来麻烦，还浪费时间。
