    yum install 安装时报yum doesn't have enough cached data to continue.

    安装epelyum -y install epel-release后,yum安装时出现如下异常:

    [root@ec-cache ~]# yum install gcc
    已加载插件:fastestmirror
    base                                                                                                                                                      | 3.6 kB  00:00:00
    
    
     One of the configured repositories failed (未知),
     and yum doesn't have enough cached data to continue. At this point the only
     safe thing yum can do is fail. There are a few ways to work "fix" this:
    
         1. Contact the upstream for the repository and get them to fix the problem.
    
         2. Reconfigure the baseurl/etc. for the repository, to point to a working
            upstream. This is most often useful if you are using a newer
            distribution release than is supported by the repository (and the
            packages for the previous distribution release still work).
    
         3. Disable the repository, so yum won't use it by default. Yum will then
            just ignore the repository until you permanently enable it again or use
            --enablerepo for temporary usage:
    
                yum-config-manager --disable <repoid>
    
         4. Configure the failing repository to be skipped, if it is unavailable.
            Note that yum will try to contact the repo. when it runs most commands,
            so will have to try and fail each time (and thus. yum will be be much
            slower). If it is a very temporary problem though, this is often a nice
            compromise:
    
                yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
    
    Cannot retrieve metalink for repository: epel/x86_64. Please verify its path and try again
    

    解决办法:
    1、将/etc/yum.repos.d/epel.repo中的mirrorlist改为baseurl

    [root@ec-cache ~]# /usr/bin/vi /etc/yum.repos.d/epel.repo
    
    [epel]
    name=Extra Packages for Enterprise Linux 7 - $basearch
    baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
    #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch
    failovermethod=priority
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
    
    [epel-debuginfo]
    name=Extra Packages for Enterprise Linux 7 - $basearch - Debug
    baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch/debug
    #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch
    failovermethod=priority
    enabled=0
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
    gpgcheck=1
    
    [epel-source]
    name=Extra Packages for Enterprise Linux 7 - $basearch - Source
    baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS
    #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch
    failovermethod=priority
    enabled=0
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
    gpgcheck=1
    

    2、/etc/resolv.conf文件中增加nameserver 144.144.144.144

    [root@ec-cache ~]# vi /etc/resolv.conf
    
    # Generated by NetworkManager
    nameserver 192.168.1.2
    nameserver 144.144.144.144
    

    3、再次执行即可
