Centos7更换yum镜像源

1、首先备份/etc/yum.repos.d/CentOS-Base.repo

  1. mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)
以CentOS7-Base-163.repo为例

  1. # CentOS-Base.repo
  2. #
  3. # The mirror system uses the connecting IP address of the client and the
  4. # update status of each mirror to pick mirrors that are updated to and
  5. # geographically close to the client. You should use this for CentOS updates
  6. # unless you are manually picking other mirrors.
  7. #
  8. # If the mirrorlist= does not work for you, as a fall back you can try the 
  9. # remarked out baseurl= line instead.
  10. #
  11. #
  12. [base]
  13. name=CentOS-$releasever - Base - 163.com
  14. #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
  15. baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/
  16. gpgcheck=1
  17. gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
  19. #released updates
  20. [updates]
  21. name=CentOS-$releasever - Updates - 163.com
  22. #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
  23. baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/
  24. gpgcheck=1
  25. gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
  27. #additional packages that may be useful
  28. [extras]
  29. name=CentOS-$releasever - Extras - 163.com
  30. #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
  31. baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/
  32. gpgcheck=1
  33. gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
  35. #additional packages that extend functionality of existing packages
  36. [centosplus]
  37. name=CentOS-$releasever - Plus - 163.com
  38. baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/
  39. gpgcheck=1
  40. enabled=0
  41. gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

注意文件中$releasever有可能对应不上要手动写死
3、运行以下命令生成缓存

  1. yum clean all
  2. yum makecache

4、yum代理
在/etc/yum.conf中加入下面几句.

  1. vim /etc/yum.conf
  2. proxy=http://210.45.72.XX:808
  3. proxy_username=username
  4. proxy_password=password
