系统版本如下uanme -a:

Setting up Update Process
No Packages marked for Update
1.卸载自带yum源
[root@localhost ~]# rpm -aq | grep yum | xargs rpm -e --nodeps
[root@localhost ~]# whereis yum
yum: /etc/yum
[root@localhost ~]# rm -rf /etc/yum
2.下载阿里yum安装包
此处用的CentOS6:下载地址执行命令，下载以下安装包（更新于2019/07/22）：
wget https://mirrors.aliyun.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm --no-check-certificate
wget https://mirrors.aliyun.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm --no-check-certificate
wget https://mirrors.aliyun.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm --no-check-certificate
wget https://mirrors.aliyun.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm --no-check-certificate
3. 安装yum相关rpm包
安装python*
[root@localhost ~]# rpm -ivh python*
warning: python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
Preparing... ########################################### [100%]
1:python-iniparse ########################################### [100%]
安装yum*,如果出现以下报错
[root@localhost ~]# rpm -ivh yum*
warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
error: Failed dependencies:
python-urlgrabber >= 3.9.1-10 is needed by yum-3.2.29-81.el6.centos.noarch
查看系统的python信息低于3.9.1-19，
[root@localhost ~]# rpm -qa|grep python-url
python-urlgrabber-3.9.1-9.AXS4.noarch
先卸载python-urlgrabber-3.9.1-9.AXS4.noarch
[root@localhost ~]# rpm -e python-urlgrabber-3.9.1-9.el6.noarch
error: package python-urlgrabber-3.9.1-9.el6.noarch is not installed
重新下载
wget https://mirrors.aliyun.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm --no-check-certificate
安装python-urlgrabber-3.9.1-11.el6.noarch.rpm，如果出现以下提示信息：
[root@localhost ~]#rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm # 使用此方法安装可能会有如下提示信息
file /usr/lib/python2.6/site-packages/urlgrabber/grabber.py from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-9.AXS4.noarch
则需要使用强制安装：
[root@localhost ~]# rpm -ivh --force python-urlgrabber-3.9.1-11.el6.noarch.rpm
warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing... ########################################### [100%]
1:python-urlgrabber ########################################### [100%]
完成之后重新执行rpm -ivh yum*
[root@localhost ~]# rpm -ivh yum*
warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing... ########################################### [100%]

2:yum-plugin-fastestmirro########################################### [ 67%]
3:yum ########################################### [100%]
配置阿里云yum源
阿里云repo地址执行以下命令：
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
如果yum list出现404，则将CentOS-Base.repo中的$releasever全部替换为系统的版本值
[root@localhost yum.repos.d]# sed -i 's/$releasever/6/g' /etc/yum.repos.d/CentOS-Base.repo
[root@localhost]# yum clean all
[root@localhost]# yum list
