Linux使用yum install报错：Disable the repository, so yum won't use it by default

 

已加载插件：fastestmirror, langpacks

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 find a valid baseurl for repo: base/7/x86_64

 

输入ifconfig，查看ip

 

 我这个使用的是 eth0，这个每个人可能不一样，

 

 

1. 在Linux系统中输入命令:   vi  /etc/sysconfig/network-scripts/ifcfg-eth0(这个文件主要看上面使用的哪个，不是固定的)

2. 修改文件中的ONBOOT=no,将no改为yes

3. 重启服务: service network restart
