You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

解
启用您的系统上的Epel和IUS存储库。
对于64位系统，您可以在这里找到正确的软件包： http : //dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/
对于32位系统，正确的软件包在这里： http : //dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/
在找到Epel和IUS rpm软件包的正确链接之后，您可以像这样安装它们：
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-5-4.noarch.rpm
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1.0-8.ius.el5.noarch.rpm
然后导入两个存储库的GPG密钥：
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
rpm --import /etc/pki/rpm-gpg/IUS-COMMUNITY-GPG-KEY
安装yum-plugin-replace软件包：。
yum install yum-plugin-replace
您现在可以使用IUS的PHP 5.3软件包替换您的PHP 5.1.6软件包，如下所示：
yum replace php --replace-with php53u
您可以搜索更多php53u软件包，如下所示：
yum search php53u
如果您发现还要安装的php53u软件包，请从搜索结果列表中选择它们，并按如下所示进行安装：
yum install php53u-pear php53u php53u-cli php53u-common php53u-devel php53u-gd php53u-mbstring php53u-mcrypt php53u-mysql php53u-pdo php53u-soap php53u-xml php53u-xmlrpc php53u-bcmath php53u-pecl-apc php53u-pecl-memcache php53u-snmp
检查您的PHP版本 - 应该显示5.3：
php -v
[root@server1 ~]# php -v
PHP 5.3.6 (cli) (built: Aug 11 2011 23:42:10)

[root@server1 ~]#
最后重新启动您的Web服务器。 对于Apache，可以按如下方式进行：
/etc/init.d/httpd restart
