Redhat7.6配置yum源

环境为未安装如何软件Redhat 7.6初始化环境 已联网

在使用yum命令是会出现一下报错：

[root@redhat-13 ~]# yum update
Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
There are no enabled repos.
 Run "yum repolist all" to see the repos you have.
 To enable Red Hat Subscription Management repositories:
     subscription-manager repos --enable <repo>
 To enable custom repositories:
     yum-config-manager --enable <repo>

以上信息显示为：

该系统未在权利服务器上注册。 您可以使用订阅管理器进行注册。
没有启用的存储库。
运行“ yum repolist all”以查看您拥有的存储库。
要启用红帽订阅管理存储库：
subscription-manager repos-启用<repo>
要启用自定义存储库：
yum-config-manager-启用<repo>

因为Redhat的yum源需要注册，所以是无法使用的。我们可以自己配置国内的yum源来使用：

首先查看一下已经安装的yum

[root@redhat-13 ~]# rpm -qa |grep yum
yum-rhn-plugin-2.0.1-10.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-161.el7.noarch
[root@redhat-13 ~]#

删除Redhat原有的yum，并查看是否删除

[root@redhat-13 ~]# rpm -qa |grep yum|xargs rpm -e --nodeps
[root@redhat-13 ~]# rpm -qa |grep yum

然后下载Centos7的yum源：

安装Python环境

[root@redhat-13 src]# rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
Retrieving https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm

这个提示说明你已经安装成功了。然而"package python-iniparse-0.4-9.el7.noarch is already installed" 这一句说的是你已经安装过了！

下载yum包

wget (或者是rpm -ivh)https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/yum-3.4.3-167.el7.centos.noarch.rpm
wget (或者是rpm -ivh) https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget (或者是rpm -ivh) https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm

安装yum

[root@redhat-13 yum]# rpm -ivh yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-81.el6.centos.noarch.rpm

由于他们之间存在依赖关系，安装时可能或出现提示信息。这时我们可以使用“rpm -ivh * --force --nodeps”这个命令来结局依赖关系。因为“--force”可以忽略依赖关系。
