[root@ipaserver ~]# yum install ipa-server

Transaction Check Error:
  file /usr/share/man/man3/XML::SAX::Base.3pm.gz conflicts between attempted installs of perl-XML-SAX-0.96-7.el6.noarch and perl-XML-SAX-Base-1.04-1.el6.rf.noarch
  file /usr/share/man/man3/XML::SAX::Exception.3pm.gz conflicts between attempted installs of perl-XML-SAX-0.96-7.el6.noarch and perl-XML-SAX-Base-1.04-1.el6.rf.noarch

从上面可以看出是因为软件包冲突造成的

perl-XML-SAX-0.96-7.el6.noarch

 perl-XML-SAX-Base-1.04-1.el6.rf.noarch

查看yum安装时出现的

Dependencies Resolved

===========================================================================================
 Package                           Arch                 Version                                  Repository              Size

Installing:

perl-XML-SAX                   noarch               0.96-7.el6                               base                    78 k
perl-XML-SAX-Base         noarch               1.04-1.el6.rf                            rpmforge                27 k

可以看出这2个软件包用了不同的软件仓库造成了软件包的冲突

解决办法：

[root@ipaserver yum.repos.d]# vim rpmforge.repo
