CentOS 6 Yum/EPEL源报错 “404 Not Found”

现CentOS 6操作系统所设置的Yum源为国内阿里云Yum源仓库，在yum安装时报错如下

~]# yum install rpm_package_name
Loaded plugins: fastestmirror
Determining fastest mirrors
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
http://mirrors.aliyun.com/centos/6/os/x86_64/repodata/repomd.xml: [Errno 14] 
PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"

因CentOS 6 版本生命周期在2020年11月30号终止，见文末链接[1]¹，CentOS Yum上游源仅保留CentOS6 中6.10的分发Yum源，其他CentOS 6版本分支的源移至http://vault.centos.org/下。
国内的镜像源同步CentOS Yum源，大部分国内Yum镜像源已不可用

解决方法:

Yum 源

将 /etc/yum.repos.d/CentOS-Base.repo文件备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

根据当前CentOS6操作系统具体版本号，自行替换下列内容的版本号
如下为将CentOS Yum源为CentOS 6.10
vi /etc/yum.repos.d/CentOS-Base.repo
将 下列内容复制粘贴到CentOS-Base.repo

[base]
name=CentOS-6.10 - Base - vault.centos.org
failovermethod=priority
baseurl=http://vault.centos.org/6.10/os/$basearch/
gpgcheck=1
gpgkey=http://vault.centos.org/RPM-GPG-KEY-CentOS-6
 
#released updates 
[updates]
name=CentOS-6.10 - Updates - vault.centos.org
failovermethod=priority
baseurl=http://vault.centos.org/6.10/updates/$basearch/
gpgcheck=1
gpgkey=http://vault.centos.org/RPM-GPG-KEY-CentOS-6
 
#additional packages that may be useful
[extras]
name=CentOS-6.10 - Extras - vault.centos.org
failovermethod=priority
baseurl=http://vault.centos.org/6.10/extras/$basearch/
gpgcheck=1
gpgkey=http://vault.centos.org/RPM-GPG-KEY-CentOS-6
 
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-6.10 - Plus - vault.centos.org
failovermethod=priority
baseurl=http://vault.centos.org/6.10/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://vault.centos.org/RPM-GPG-KEY-CentOS-6
 
#contrib - packages by Centos Users
[contrib]
name=CentOS-6.10 - Contrib - vault.centos.org
failovermethod=priority
baseurl=http://vault.centos.org/6.10/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://vault.centos.org/RPM-GPG-KEY-CentOS-6

如要更换为其它分支版本号，other_vers 指代所要指定的版本号值
sed -i.bak ‘s/6.10/other_vers/g’ /etc/yum.repos.d/CentOS-Base.repo

yum 验证操作
yum clean all #清除缓存
yum makecache #创建缓存
yum repolist #查看源仓库情况

epel源

同样的EPEL6源 声明终止维护，见文末链接[2]².
如在用EPEL源执行软件包安装报错"404 Not Found"，同样重命名epel.repo文件,新建epel.repo, 将以下内容复制

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=https://archives.fedoraproject.org/pub/archive/epel/6/$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[epel-debuginfo]
name=Extra Packages for Enterprise Linux 6 - $basearch - Debug
baseurl=https://archives.fedoraproject.org/pub/archive/epel/6/$basearch/debug
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

[epel-source]
name=Extra Packages for Enterprise Linux 6 - $basearch - Source
baseurl=https://archives.fedoraproject.org/pub/archive/epel/6/SRPMS
failovermethod=priority

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1
