RHEL 5.7 使用rpm安装XtraBackup问题总结

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

error: Failed dependencies:

        libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.6-2.el5.x86_64

        perl(DBD::mysql) is needed by percona-xtrabackup-24-2.4.6-2.el5.x86_64

如上所示，既然缺少组件，那么安装libev.x86_64， 如下所示，本地yum源安装libev.so.4失败，只能从网上下载libev-4.15-1.el5.rf.x86_64.rpm，网址为http://rpmfind.net/linux/rpm2html/search.php

[root@DB-Server tmp]# yum -y install libev.x86_64

[root@DB-Server tmp]# yum list | grep "perl-DBD-MySQL"

perl-DBD-MySQL.x86_64                      3.0007-2.el5                media   

[root@DB-Server tmp]# yum install perl-DBD-MySQL

安装 perl-DBD-MySQL时，就会遇到大量类似下面错误

file /usr/bin/msql2mysql from install of mysql-5.0.77-4.el5_6.6.x86_64 conflicts with file from package MySQL-client-advanced-5.6.20-1.rhel5.x86_64

遇到这个错误是因为没有安装MySQL-shared-compat组件，安装了MySQL-shared-compat-advanced-5.6.20-1.rhel5.x86_64.rpm后，然后使用yum install perl-DBD-MySQL就不会遇到conflict with file的错误

[root@DB-Server tmp]# rpm -qa | grep -i mysql

MySQL-client-advanced-5.6.20-1.rhel5
