尝试在CentOS 6上安装mcrypt。
在阅读其他帖子后，我了解到yum正在使用epel 5，当需要使用epel 6时。
所以，我删除了epel：
$ yum remove epel-release
得到了第6条：
$ wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
$ rpm -ivh epel-release-6-8.noarch.rpm
我的epel.repo文件如下：
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

所有指向epel 6的东西......对吗？
好吧，使用$ yum install php-mcrypt，会抛出此错误：
Package: php-mcrypt-5.1.6-5.el5.x86_64 (epel)
Requires: php-api = 20041225
仍然从Epel 5中拉出来？发生了什么......我怎样才能让百胜使用Epel 6？
