尝试使用http://www.how2centos.com/installing-php-5-4-on-centos-5-8/上的教程从PHP 5.3升级到5.4。我基本上说要做以下事情：
yum install yum-priorities
rpm -Uvh http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1.0-10.ius.el5.noarch.rpm
yum install php54 php54-common php54-devel
执行第二行时，出现以下错误：
[root@localhost ~]# rpm -Uvh http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
Retrieving http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
error: skipping http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm - transfer failed - Unknown or unexpected error
warning: u 0xc073650 ctrl 0xc074a20 nrefs != 0 (download.fedoraproject.org http)
我做错了什么？感谢
答案 0 :(得分：3)
那是因为download.fedoraproject.org正在重定向到镜像。 RHEL 5中的RPM不遵循（尚未）。 尝试用直接主机名替换它（例如dl.fedoraproject.org）。
