See what happens with curl -v 'http://mirrorlist.centos.org/?repo=os&arch=x86_64&release=7'

Perhaps that will lead you to find the source of the problem.

OK, that looks good. Please show the full output of "yum update". There should be other errors shown before the "Cannot find a valid baseurl" message.

Additionally, are you using a proxy? Should you be using a proxy? If a proxy is involved or if you think it might be involved, see the proxy config in /etc/yum.conf

here is yum update...
[root@myserver oracle]# yum update

One of the configured repositories failed (Unknown),
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=<repoid> ...

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 <repoid>
or
subscription-manager repos --disable=<repoid>

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=<repoid>.skip_if_unavailable=true

Can you show us the contents of /etc/yum.repos.d/CentOS-Base.repo please.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

And what is the output from rpm -q --qf '%{version}\n' centos-release and the content of /etc/yum.conf?

Is there really nothing between these lines?
