rhel-server不能安装LNMP了吗？
我用rhel-server-7.4-x86安装lnmpa结果显示失败，我二个月前用rhel-server-7.3-x86_64-dvd还是可以的，我又用rhel-server-7.3-x86_64-dvd安装了一遍结果还是失败，请军哥给我看看。谢谢Loaded plugins: product-id, search-disabled-repos, subscription-manager

http://mirrors.163.com/centos/7/os/x86_64/repodata/repomd.xml: Error importing repomd.xml for base: Damaged repomd.xml file
Trying other mirror.
One of the configured repositories failed (CentOS-7 - Base - 163.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. 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: No more mirrors to try.
你机器可能连不上163的源，换个其他源试试 谢谢军哥回复！怎么更换其他源呢需要改哪个文件？或者给我个网页教程。以前是可以连上的。
