之前也遇到过类似报错，不过网站都没记录，这次记录下。实际网页上的资料也都是有很多的正确解决方案。
问题如下，通过官网下载的XtraBackup rpm包，安装XtraBackup 这个mysql备份工具报错如下：
[root@mysql src]# rpm -ivh percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm warning: percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY error: Failed dependencies: perl(DBD::mysql) is needed by percona-xtrabackup-22-2.2.13-1.el6.x86_64 perl(Time::HiRes) is needed by percona-xtrabackup-22-2.2.13-1.el6.x86_64 [root@mysql src]# yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL
解决办法如下：
yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL
再次重新安装，问题解决。
