Redhat6.7 切换Centos yum源

RedHat 更换Yum源

1.检查yum包 rpm -qa |grep yum

2.删除自带包

rpm -aq | grep yum | xargs rpm -e --nodeps

3.再检查一下

rpm -qa |grep yum

4.下载更新包

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
wget  http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-73.el6.centos.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-updateonboot-1.1.30-37.el6.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-utils-1.1.30-37.el6.noarch.rpm

 

5.执行安装

rpm -ivh yum-*

如果出现

error: Failed dependencies:

        python-urlgrabber >= 3.9.1-10 is needed by yum-3.2.29-73.el6.centos.noarch

不要慌，这个问题很恶心会导致后面安装前功尽弃，使用下面

rpm -Uvh python-urlgrabber-3.9.1-11.el6.noarch.rpm

更新rpm -Uvh python-urlgrabber版本，不更新肯定安装不过去

在执行：

rpm -ivh yum-*

 

warning: yum-3.2.29-73.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

安装成功了

6.切换源

cd /etc/yum.repos.d/ 

mv redhat.repo redhat.repo.bak

mv rhel-source.repo rhel-source.repo.bak

vi /etc/yum.repos.d/CentOS-Base.repo

粘贴如下信息：

 

#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.
