在Red Hat Enterprise Linux Server release 5.7 (Tikanga)上使用RPM方式安装Percona Xtrabackup 2.4.6时遇到了一些问题，特意总结在此。
[root@DB-Server tmp]#yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL
安装相关依赖组件时，遇到conflict with file的错误，如上截图所示，然后安装Percona Xtrabackup 2.4.6是就会遇到下面错误:
[root@DB-Server tmp]# rpm -ivh percona-xtrabackup-24-2.4.6-2.el5.x86_64.rpm
warning: percona-xtrabackup-24-2.4.6-2.el5.x86_64.rpm: Header V4 DSA signature: NOKEY, key ID cd2efd2a
