      Linux yum出错 Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again,


      Linux下使用yum命令时报错Error: Cannot retrieve repository metadata (repomd.xml) for repository......,具体如下所示

       [root@localhost yum.repos.d]# yum makecache
      Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
      This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
      Repository base is listed more than once in the configuration
      file:///media/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/repodata/repomd.xml
      Trying other mirror.
      Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
      [root@localhost yum.repos.d]# ls /media -hl
      total 3633166
      dr-x------.  1 root root 8.0k Sep 14 20:32 CDROM
      dr-xr-xr-x. 12 root root 8.0k Jan 30  2013 RHEL_6.4 x86_64 Disc 1
      -rwxr-xr-x.  1 root root 3.5G Dec 16  2015 rhel-server-6.4-x86_64-dvd.iso

      请注意观察错误信息,在Error上有提示:

      file:///media/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/repodata/repomd.xml

      意思是说repomd文件没有找到,这会导致yum命令无法检索存储库元数据(翻译的,或者理解为找不到库);即需要让yum命令能找到这个文件,这个文件默认在系统安装光盘的/repodata/目录下;

      检查yum配置信息,到/etc/yum.repos.d/下检查配置的repo文件:

      [root@localhost /]# cd /etc/yum.repos.d/
      [root@localhost yum.repos.d]# ls -l
      total 8
      drwxr-xr-x. 2 root root 4096 Oct 11 02:04 bak_repo
      -rwxr-xr-x. 1 root root  162 Oct 11 01:36 rhel-base.repo
      [root@localhost yum.repos.d]# more rhel-base.repo
      [base]
      name=RedHat
      baseurl=file:///media/
      enabled=1
      gpgcheck=0
      gpgkey=file:///media/RPM-GPG-KEY-redhat-release

      这里关系到如何配置本地yum源,对于如何配置yum源,可以参考:

      http://www.1click-soft.com/tfgjylgw/Wherebolezi/p/4626670.html

      在本地yum配置文件上,可以看到yum指向本地的/media/文件;/media目录如下

      [root@localhost yum.repos.d]# ls /media -hl
      total 3.5G
      dr-x------.  1 root root 2.0K Sep 14 20:32 CDROM
      dr-xr-xr-x. 12 root root 8.0K Jan 30  2013 RHEL_6.4 x86_64 Disc 1
      -rwxr-xr-x.  1 root root 3.5G Dec 16  2015 rhel-server-6.4-x86_64-dvd.iso

      通过以上信息,表示/media目录下不存在repomd.xml文件,这个文件在RHEL_6.4 x86_64 Disc 1中;可以通过修改yum配置让系统能找到文件

      修改后的内容如下(注意目录中的空格前需要\转义符):

      [base]
      name=RedHat
      baseurl=file:///media/RHEL_6.4\ x86_64\ Disc\ 1
      enabled=1
      gpgcheck=0
      gpgkey=file:///media/RHEL_6.4\ x86_64\ Disc\ 1/RPM-GPG-KEY-redhat-release

      然后清理: yum clean all

      yum makecache

      结果如下所示:

      [root@localhost yum.repos.d]# yum clean all
      Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
      This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

      没有 Error: Cannot retrieve.....内容,且没有Could not open/read file......等打不开文件的提示,即表示问题已解决

      如果问题仍然存在,则需要核对下安装光盘与系统本身是否匹配,或者yum源与系统版本的匹配程度,然后多执行几次yum clean all --> yum makecache观察情况
