报错信息

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.
http://mirrors.sohu.com/centos/7/addons/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

解决方案

1.  请先确定你是无法联网还是配置问题。

ping www.baidu.com 如果是正常ping那可以看这个帖子完成配置

2.  如果是 ping 有问题,那就:

      1. 在Linux系统中输入命令:   vi  /etc/sysconfig/network-scripts/ifcfg-ens33

      2. 修改文件中的ONBOOT=no,将no改为yes

      3. 重启服务: service network restart

在测试 ping 再去yum 应该可以了
