centos 更换源出现问题

[水静流深308]

安装centos后，准备配置163的源

cd /etc/yum.repos.d
mv CentOS-Base.repo CentOS-Base.repo.bk
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
mv CentOS6-Base-163.repo CentOS-Base.repo
yum clean all
yum update
yum makecache
出现问题：

One of the configured repositories failed (CentOS-7 - Addons - sohu.com),
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 addons

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=addons.skip_if_unavailable=true

failure: repodata/repomd.xml from addons: [Errno 256] No more mirrors to try.

请问，如何解决？163的源不可以用了吗？

那我怎么办？可否给个centos7下面可以用的 CentOS-Base.repo 配置文件？

http://mirrors.163.com/.help/CentOS7-Base-163.repo 换成7.X版本应该就好了把。

你的源地址是错误，你必须根据你得到的地址能找到那个repond.xml文件，我看了一下，好像是这个地址 http://mirror.centos.org/centos/7/os/x86_64/repodata/ 在7这个目录下是没有addons这个文件夹的。

更换配置文件中的地址就好了，其他的就不需要改变了

[sing a song_^^]

同求：！！！！！我在曙光公司的服务器上安装centos 7，提示错误no more mirrors to try

[放心飞吧]
