卸载yum

[root@omr ~]# rpm -aq|grep yum|xargs rpm -e –nodeps
[root@omr yum_install]# yum
-bash: /usr/bin/yum: No such file or directory

下载安装所需rpm包

python-iniparse-0.3.1-2.1.el6.noarch.rpm
python-urlgrabber-3.9.1-11.el6.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
yum-3.2.29-73.el6.centos.noarch.rpm

安装yum

[root@omr yum_install]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
warning: python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY

这两个rpm包要同时安装
[root@omr yum_install]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
warning: yum-3.2.29-73.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-3.2.29-73.el6.centos.noarch
提示python-urlgrabber版本不兼容先卸载后安装
[root@omr yum_install]# rpm -qa | grep python-urlgrabber
python-urlgrabber-3.9.1-9.el6.noarch
[root@omr yum_install]# rpm -e python-urlgrabber-3.9.1-9.el6.noarch
[root@omr yum_install]# rpm -qa | grep python-urlgrabber
[root@omr yum_install]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm

1:python-urlgrabber ########################################### [100%]
[root@omr yum_install]# rpm -qa | grep python-urlgrabber
python-urlgrabber-3.9.1-11.el6.noarch

然后再次执行安装yum
[root@omr yum_install]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
warning: yum-3.2.29-73.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

2:yum ########################################### [100%]
[root@omr yum_install]#

ps.中间50%是正常的

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
