redhat7.3配置163 yum源

redhat 的更新包只对注册的用户生效，所以我们需要自己手动更改成CentOS 的更新包，CentOS几乎和redhat是一样的，所以无需担心软件包

redhat 的更新包只对注册的用户生效，所以我们需要自己手动更改成CentOS 的更新包，CentOS几乎和redhat是一样的，所以无需担心软件包是否可安装，安装之后是否有问题。

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

rpm -aq|grep python-iniparse|xargs rpm -e --nodeps

2、下载163的yum 安装包

wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-3.4.3-150.el7.centos.noarch.rpm

wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm

wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

3、安装下载的rpm包

rpm -ivh *.rpm

4、创建文件/etc/yum.repos.d/rhel-debuginfo.repo并写入

[base]

name=CentOS-$releasever - Base

baseurl=http://mirrors.163.com/centos/7.3.1611/os/$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7

name=CentOS-$releasever - Updates

baseurl=http://mirrors.163.com/centos/7.3.1611/updates/$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7

name=CentOS-$releasever - Extras

baseurl=http://mirrors.163.com/centos/7.3.1611/extras//$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7

[centosplus]

name=CentOS-$releasever - Plus

baseurl=http://mirrors.163.com/centos/7.3.1611/centosplus//$basearch/

gpgcheck=1

enabled=0

5、 yum clean all

6、 yum update 测试。

7、 安装 epel 源

yum install epel-release
