CentOS 7.2: Yum repo configuration fails
23,145
Solution 1
After more sleuthing, I figured it out. There was a directory hierarchy missing, and yum couldn't detect my CentOS version. Running the following commands fixed it right up:
mkdir -p /etc/yum/vars
echo 7.2.1511 > /etc/yum/vars/releasever
Replace "7.2.1511" with your own release version if you are having this problem and nothing else has worked.
UPDATE 5/21/2017: The "7.2.1511" path has been deprecated. Run the following command to keep yum working if you are still on CentOS 7.2.1511:
echo 7 > /etc/yum/vars/releasever
That should take care of it, should you suddenly discover that yum has stopped working.
Solution 2
A workaround is to run the following command .
rm -fr /var/cache/yum/x86_64/7
yum clean all
This worked for me. CentOS Linux release 7.2.1511 (Core)

Fresh install of CentOS 7.2.1511. Server was originally configured with Network Manager and yum was working fine. Recently disabled Network Manager and configured network with traditional service (/etc/sysconfig/network-scripts). New IP addresses were assigned to the NIC's. Setup was originally on a 10.x.x.x network, is now on a 192.168.x.x network.
When I try to run yum I get the following error:
Loaded plugins: fastestmirror, langpacks http://mirror.centos.org/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. To address this issue please refer to the below knowledge base article https://access.redhat.com/articles/1320623 If above article doesn't help to resolve this issue please create a bug on https://bugs.centos.org/ http://mirror.centos.org/centos/%24releasever/extras/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. One of the configured repositories failed (CentOS-$releasever - Extras), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable extras 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=extras.skip_if_unavailable=true failure: repodata/repomd.xml from extras: [Errno 256] No more mirrors to try. http://mirror.centos.org/centos/$releasever/extras/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not FoundHere are the setups for the network interfaces. em1 and em2 have the same basic config:
