Question

我正在使用centos 7.在一些测试中，我不小心删除了yum.repo.d中的所有文件。有没有办法，下载和配置centos 7中的所有基本回购

Answer 1

假设您正在运行CentOS-7.3，您可以通过以下方式取回repo文件，

op :-
  keyword(a),
  ( keyword(b) ->
    ( keyword(c) ->
      write('Answer A, B and C'), nl
    ; write('Answer A and B'), nl )
  ; write('Answer A'), nl ).

# ReInstall the centos-release rpm ~]# rpm -Uvh --force \ http://mirror.centos.org/centos-7/7/os/x86_64/Packages/centos-release-7-3.1611.el7.centos.x86_64.rpm # Clean YUM cache ~]# yum clean all # Try an update ~]# yum update RPM包含所有repo文件，

centos-release

Answer 2

#!/bin/bash

install-centos-release() {
 releasever="$(rpm -q --qf '%{VERSION}' "$(rpm -q --whatprovides centos-release)")" \
 && releasever="$(printf "%s" "$releasever" | sed -e 's/\..*$//g')" \
 && basearch="$(uname -m)" \
 && reposurl=$(printf "%s" "http://mirror.centos.org/centos/$releasever/os/$basearch/Packages/") \
 && releaserpm=$(curl --silent "$reposurl" | grep -oP '(?<=")centos-release.*.rpm(?=")') \
 && releaseuri=$(printf "%s%s" "$reposurl" "$releaserpm") \
 && rpm -Uvh --force "$releaseuri"
}

用法：

# Either launch a new terminal and copy `install-centos-release` into the current shell process, 
# or create a shell script and add it to the PATH to enable command invocation with bash.

install-centos-release

# Refresh YUM repository(ies)
yum clean all
yum -y update

旧的好的复制/粘贴方法有权使用：
