日常工作问题解决：redhat6.9--解决yum功能不能正常使用和配置yum源

时间：2023-12-20 14:57:26

1、问题描述

解决RedHat6.9下yum功能不能用问题：

在redhat6.9下使用yum安装时，会提示：This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

由于centos6.9和redhat6.9版本一致，所以可以卸载原有yum，用centos6.9的yum替代

注意：配置之前做好域名解析，修改：/etc/resolv.conf

在文件末尾加入：

nameserver 114.114.114.114

nameserver 8.8.8.8

如下所示：



-bash-4.1$ cat /etc/resolv.conf

# Generated by NetworkManager

# No nameservers found; try putting DNS servers into your

# ifcfg files in /etc/sysconfig/network-scripts like so:

#

# DNS1=xxx.xxx.xxx.xxx

# DNS2=xxx.xxx.xxx.xxx

# DOMAIN=lab.foo.com bar.foo.com

nameserver 8.8.8.8

nameserver 114.114.114.114

2、解决办法

2.1 卸载原生yum

查看已安装yum版本

rpm -qa|grep yum

卸载已安装yum

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

创建rpm包存放文件夹

mkdir /opt/yum-package

2.2 安装新yum

下载rpm包

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-3.2.29-81.el6.centos.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

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

安装相关rpm包

rpm -ivh yum*

配置yum源(这里使用的是164的yum源)

cd /etc/yum.repos.d/

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

备份原有yum源

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

将CentOS6-Base-163.repo文件中的所有的$releaserver替换为6

sed -i "s#\$releasever#6#g" CentOS6-Base-163.repo

2.3 重建yum

重建yum

yum clean all

yum makecache
