redhat7 配置centos7yum源

1.首先删除redhat原有的yum ，因为redhat 原本的yum 没有注册为redhat用户是用不了的。

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

 

 

2下载163的yum 安装包

 

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm

 

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-118.el7.centos.noarch.rpm

 

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

 

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-24.el7.noarch.rpm

 

 

3.进行安装yum 

rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
rpm -ivh yum-3.4.3-118.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-24.el7.noarch.rpm  
注意最后两个包必需同时安装，否则会相互依赖 

 

 

 

 

4.更新repo文件

 

mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.repo.bak

 

如果没有这个文件就直接创建

 

sudo nano /etc/yum.repos.d/rhel-debuginfo.repo

 

在文件中写入

 

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/7/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7


#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/7/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7


[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.163.com/centos/7/extras//$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/7/centosplus//$basearch/
gpgcheck=1
enabled=0

 

保存退出

5 yum clean all 

6 yum update 测试。

 

7 安装 epel 源

 

sudo yum install epel-release

 

如果不行就手动下载安装

 

wget https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

 

sudo yum install epel-release-7-5.noarch.rpm

$ sudo yum repolist检查是否安装成功
