Redhat7.6配置yum源

環境為未安裝如何軟件Redhat 7.6初始化環境 已聯網

在使用yum命令是會出現一下報錯：

[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>

以上信息顯示為：

該系統未在權利服務器上注冊。 您可以使用訂閱管理器進行注冊。
沒有啟用的存儲庫。
運行“ yum repolist all”以查看您擁有的存儲庫。
要啟用紅帽訂閱管理存儲庫：
subscription-manager repos-啟用<repo>
要啟用自定義存儲庫：
yum-config-manager-啟用<repo>

因為Redhat的yum源需要注冊，所以是無法使用的。我們可以自己配置國內的yum源來使用：

首先查看一下已經安裝的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 ~]#

刪除Redhat原有的yum，並查看是否刪除

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

然后下載Centos7的yum源：

安裝Python環境

[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

這個提示說明你已經安裝成功了。然而"package python-iniparse-0.4-9.el7.noarch is already installed" 這一句說的是你已經安裝過了！

下載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

安裝yum

由於他們之間存在依賴關系，安裝時可能或出現提示信息。這時我們可以使用“rpm -ivh * --force --nodeps”這個命令來結局依賴關系。因為“--force”可以忽略依賴關系。
