阿里云CentOS源镜像地址404错误解决办法

由 渔夫人 发布于 2021-12-01

囧！囧！囧！查了N多资料折腾成功后，发现官方有提供换源的资料。 https://help.aliyun.com/document_detail/193569.htm

今天升级Python版本由于缺少组件编译未通，使用yum安装提示镜像地址404错误，提示如下。

  1. http://mirrors.cloud.aliyuncs.com/epel/6/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"

找到阿里云官方镜像说明对照一顿操作后，然并卵。继续404！

最后在阅尽无数帖子后发现一个可以访问的镜像地址，我试着将地址中的版本号改成服务器的仍然可以访问，大喜。先找到/etc/yum.repos.d/epel.repo文件修改其中的内容。

  1. [epel]
  2. name=Extra Packages for Enterprise Linux 6 - $basearch
  3. enabled=1
  4. failovermethod=priority
  5. #baseurl=http://mirrors.cloud.aliyuncs.com/epel/6/$basearch
  6. #注释原来的地址改成下面的
  7. baseurl=http://mirrors.aliyun.com/centos-vault/6.5/extras/$basearch
  8. #解析后的地址 https://mirrors.aliyun.com/centos-vault/6.5/extras/x86_64/repodata/repomd.xml
  9. gpgcheck=0
  10. gpgkey=http://mirrors.cloud.aliyuncs.com/epel/RPM-GPG-KEY-EPEL-6

再修改/etc/yum.repos.d/CentOS-Base.repo文件内容（github上找的），适用CentOS6.X的版本

  1. [base]
  2. name=CentOS-$releasever - Base - mirrors.aliyun.com
  3. failovermethod=priority
  4. baseurl=http://mirrors.aliyun.com/centos-vault/6.5/os/$basearch/
  5.         http://mirrors.aliyuncs.com/centos-vault/6.5/os/$basearch/
  6.         http://mirrors.cloud.aliyuncs.com/centos-vault/6.5/os/$basearch/
  7. gpgcheck=1
  8. gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
  10. #released updates
  11. [updates]
  12. name=CentOS-$releasever - Updates - mirrors.aliyun.com
  13. failovermethod=priority
  14. baseurl=http://mirrors.aliyun.com/centos-vault/6.5/updates/$basearch/
  15.         http://mirrors.aliyuncs.com/centos-vault/6.5/updates/$basearch/
  16.         http://mirrors.cloud.aliyuncs.com/centos-vault/6.5/updates/$basearch/
  17. gpgcheck=1
  18. gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
  20. #additional packages that may be useful
  21. [extras]
  22. name=CentOS-$releasever - Extras - mirrors.aliyun.com
  23. failovermethod=priority
  24. baseurl=http://mirrors.aliyun.com/centos-vault/6.5/extras/$basearch/
  25.         http://mirrors.aliyuncs.com/centos-vault/6.5/extras/$basearch/
  26.         http://mirrors.cloud.aliyuncs.com/centos-vault/6.5/extras/$basearch/
  27. gpgcheck=1
  28. gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
  30. #additional packages that extend functionality of existing packages
  31. [centosplus]
  32. name=CentOS-$releasever - Plus - mirrors.aliyun.com
  33. failovermethod=priority
  34. baseurl=http://mirrors.aliyun.com/centos-vault/6.5/centosplus/$basearch/
  35.         http://mirrors.aliyuncs.com/centos-vault/6.5/centosplus/$basearch/
  36.         http://mirrors.cloud.aliyuncs.com/centos-vault/6.5/centosplus/$basearch/
  37. gpgcheck=1
  38. enabled=0
  39. gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
  41. #contrib - packages by Centos Users
  42. [contrib]
  43. name=CentOS-$releasever - Contrib - mirrors.aliyun.com
  44. failovermethod=priority
  45. baseurl=http://mirrors.aliyun.com/centos-vault/6.5/contrib/$basearch/
  46.         http://mirrors.aliyuncs.com/centos-vault/6.5/contrib/$basearch/
  47.         http://mirrors.cloud.aliyuncs.com/centos-vault/6.5/contrib/$basearch/
  48. gpgcheck=1
  49. enabled=0
  50. gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6

而后注释掉/etc/cloud/cloud.cfg文件中的- source address模块（前面加#即可）

  1. ...
  2. cloud_init_modules:
  3.  - migrator
  4. # - source-address
  5.  - seed_random
  6. ....

最后执行更新命令yum clean all && yum makecache
