मेरे पास नवीनतम सेंटो 7 की एक ताजा स्थापना है
[root@localhost ~]# cat /etc/centos-release
CentOS Linux release 7.4.1708 (Core)
[root@localhost ~]#
मैं कुछ स्थापित करना चाहता था और wget स्थापित नहीं था इसलिए जब मैंने wget स्थापित करने का प्रयास किया तो मैंने देखा कि tha yum त्रुटि दे रहा है।
मैंने इंटरनेट पर इस समस्या के बारे में सभी विषयों को देखा, लेकिन कोई भी भाग्य मुझे अपना समाधान नहीं मिला।
[root@localhost ~]# yum update

One of the configured repositories failed (CentOS-7 - Base),
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. Run the command with the repository temporarily disabled
yum --disablerepo=base ...
4. Disable the repository permanently, 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 base
or
subscription-manager repos --disable=base
5. 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=base.skip_if_unavailable=true
failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.

इसलिए जब मैं रिपोज को सूचीबद्ध करता हूं तो मुझे यह मिलता है:
[root@localhost ~]# yum repolist all

मुझे यकीन नहीं है कि समस्या कहां हो सकती है मेरे vmware / OVH समर्पित सर्वर पर एक नई स्थापना।
मेरे पास एक और सर्वर स्थापित है और ठीक काम कर रहा है लेकिन इस बार मुझे यह समस्या आई।
कोई भी मेरी मदद कर सकता है? मैंने आदि / yum.repo.d में सभी अक्षम लाइनों को सक्षम करने का प्रयास किया है
my /etc/yum.repos.d/CentOS-Base.repo
