Memcached安装问题

Question

我正在尝试将memcached安装到RedHatEnterprise5.5 x86_64

我试过：

root@sv [~]# yum -y install memcached

然后收到以下错误

 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

这是否意味着我需要术语：：ReadKey，AnyEvent::Socket，AnyEvent等等来安装memcached？当我试图安装"AnyEvent“时，这也给我带来了一些问题。

用户: Stephan建议更新一些perl模块，但这对我来说行不通。在更新了两个模块之后，我再次运行了yum，这是结果。

root@sv [~]# yum -y install memcached

Answer 1

在我的例子中，在CentOS 5.5 x86_64上，我在以下方面取得了成功：

sudo yum --enablerepo=rpmforge,rpmforge-extras install memcached

显然，您需要RPMForge才能使其工作。(既然yum日志提到了rpmforge，@Maca似乎已经有了。)

问题是所需的版本包含在rpmforge-extras存储库中，默认情况下该存储库被禁用。

虽然与问题中不同的一揽子办法是有问题的，但同样的理由和解决办法也可能适用。

Answer 2

CentOS的yum存储库没有memcached所需的最新和包。我在谷歌上搜索了一下，发现其他人也遇到了类似的问题。下面是一个简单的解决方法：

首先，删除旧的perl模块。然后下载并安装memcached所需的更新版本。

rpm-e perl-Net-SSLeay-1.30-4.fc6
rpm -e perl-IO-Socket-SSL-1.01-1.fc6
wget http://packages.sw.be/perl-Net-SSLeay/perl-Net-SSLeay-1.36-1.el5.rfx.i386.rpm
wget http://packages.sw.be/perl-Net-SSLeay/perl-Net-SSLeay-1.36-1.el5.rfx.x86_64.rpm
wget http://packages.sw.be/perl-IO-Socket-SSL/perl-IO-Socket-SSL-1.34-1.el5.rfx.noarch.rpm
rpm -i perl-Net-SSLeay-1.36-1.el5.rfx.x86_64.rpm
rpm -i perl-Net-SSLeay-1.36-1.el5.rfx.i386.rpm
rpm -i perl-IO-Socket-SSL-1.34-1.el5.rfx.noarch.rpm

现在，您应该能够毫无错误地安装memcached。

您的虚拟化工具或控制面板在yum配置中禁用了某些包；有关如何修复此问题，请咨询上述工具的开发人员。
