redhat替换centOS yum

1. 删除原有的yum源

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

 

 

2.下载新的yum安装包，这里使用centos-6.5

# wget http://mirror.centos.org/centos/6.5/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
# wget http://mirror.centos.org/centos/6.5/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
# wget http://mirror.centos.org/centos/6.5/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
# wget http://mirror.centos.org/centos/6.5/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 

 

 

3.安装yum软件包

# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
# rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
# rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 

 

 

4. 更改yum源

在/etc/yum.repos.d/新建文件centos.repo,内容如下：

# CentOS-Base.repo ###################begin#################################
#
# 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.
#
[base]
name=CentOS-6.5 – Base
#mirrorlist=http://mirrorlist.centos.org/?release=6.5&arch=$basearch&repo=os
baseurl=http://mirror.centos.org/centos/6.5/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6.5&arch=$basearch&repo=centosplus

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#contrib – packages by Centos Users
[contrib]
name=CentOS-6.5 – Contrib
#mirrorlist=http://mirrorlist.centos.org/?release=6.5&arch=$basearch&repo=contrib

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
##########################end######################################## 

 

 

注意：

1.   6.5为版本（可替换）；

2.   如果RPM-GPG-KEY-CentOS-6不存在则新建，下载地址：http://mirror.centos.org/centos/6.5/os/x86_64/RPM-GPG-KEY-CentOS-6

 

5.清理yum缓存

# yum clean all
# yum makecache #将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度
# yum install lrzsz #测试新源是否可用
