yum中找不到包时候解决方式

有时候使用yum安装memcached或者redis时候,发现not found package时候,在网络中搜索很一堆方法,发现fedora开源的一个包很好用,那就是epel-release,我们以安装redis为例子

 下面有EPEL解释

1. 什么是企业版 Linux 附加软件包(EPEL)?

企业版 Linux 附加软件包(以下简称 EPEL)是一个由特别兴趣小组创建、维护并管理的,针对 红帽企业版 Linux(RHEL)及其衍生发行版(比如 CentOS、 Scientific Linux)的一个高质量附加软件包项目。

EPEL 的软件包通常不会与企业版 Linux 官方源中的软件包发生冲突,或者互相替换文件。EPEL 与 Fedora 项目基本一致,包含完整的构建系统、升级管理器、镜像管理器等等。

您可以到任意一台 EPEL 镜像服务器的目录查看:点击此处查看 EPEL 镜像的列表

或者您也可以使用 repoview 来查看:

EPEL 6: i386, x86_64, ppc64, sources
EPEL 5: i386, x86_64, ppc, sources
我怎样获取 EPEL 的软件包?

EPEL 包含一个叫做'epel-release'的包,这个包包含了 EPEL 源的 gpg 密钥和软件源信息。您可以通过 yum 安装到您的企业版 Linux 发行版上。除了 epel-release 源,还有一个叫做'epel-testing'的源,这个源包含最新的测试软件包,其版本很新但是安装有风险,请自行斟酌。

注意:
RHN 用户请注意
您也许需要启用某些'可选择的'源来安装依赖组件。这里 有一个针对 RHN 的教程。
如果您使用第6版企业版 Linux,请安装这个 RPM 包: epel-release-6-5.noarch.rpm  http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm

如果您使用第5版企业版 Linux,请安装这个 RPM 包: epel-release-5-4.noarch.rpm

http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

您可以通过: Fedora 项目公钥列表 页面来验证 EPEL 源所有包的签名。
