背景

今天在一台新服务器上安装nginx，在这个过程中需要安装相关依赖，在使用yum install命令时，发生了以下报错内容：

复制代码

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"


 One of the configured repositories failed (未知),
 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

Cannot find a valid baseurl for repo: base/7/x86_64

通过查看这个报错日志，关键在第一句：Could not retrieve mirrorlist http://mirrorlist.centos.org，无法访问该链接。

具体原因：mirrorlist.centos.org 不再被支持。

解决方法

使用sed命令批量替换CentOS镜像源。具体如下：

复制代码

sudo sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/*.repo
sudo sed -i s/^#.*baseurl=http/baseurl=https/g /etc/yum.repos.d/*.repo
sudo sed -i s/^mirrorlist=http/#mirrorlist=https/g /etc/yum.repos.d/*.repo

搞定。
