Title: Could not resolve host: mirrors.cloud.aliyuncs.com; Unknown error
Post by: algebraafrica on November 22, 2019, 11:15:03 PM
My CWP installation is starting to fail at the "CentOS Web Panel MailServer Installer"  stage. May you please assist me. where I am going wrong? I am installing in Centos 7. I can not ping this host mirrors.cloud.aliyuncs.com.

Below is the full error message:

 One of the configured repositories failed (CentOS-7),
 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

Hi, I just get this error yesterday
you should check in

/etc/yum.repos.d

Move all repo files in the /etc/yum.repos.d/ directory to another directory, such as /tmp/. Then download Centos-7.repo.
$ mv *.repo /tmp/
$ wget http://mirrors.aliyun.com/repo/Centos-7.repo
$ yum clean all
$ yum makecache

hope this will work for you
