Redhat7安裝yum源

前言：想要在伺服器Redhat7 安裝gcc   使用yum   install gcc  報錯：

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

原因是Redhat的yum需要注冊。這裡想辦法安裝了CentOS的yum源

一、解除安裝原來的yum

#檢視原來是否安裝
rpm -qa |grep yum    

#解除安裝本機yum
rpm -qa|grep yum|xargs rpm -e --nodeps 

# 檢視yum是否解除安裝幹淨
rpm -qa |grep yum
           

二、下載下傳yum替換包

這裡要說明一下，因為要替換，是以一定要是一整套，還有一個rhel-debuginfo.repo檔案要配置。

我這裡準備了yum包，已上傳到csdn資源。在公司Redhat伺服器已經安裝成功。下載下傳路徑：https://download.csdn.net/download/kzdwts/10586712

可以先建一個檔案夾，然後把5個安裝包拷貝到 yum 這個檔案下面

執行:

rpm -ivh *.rpm
           

 一次性執行依賴包，因為包之間會互相依賴。

第三步：建立配置 .repo檔案

vim /etc/yum.repos.d/CentOS-Base.repo
           

輸入内容如下：

#CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$7 - Base - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=os
baseurl=http://mirrors.163.com/centos/7/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7


#released updates
[updates]
name=CentOS-$7 - Updates - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=updates
baseurl=http://mirrors.163.com/centos/7/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7


#additional packages that may be useful
[extras]
name=CentOS-$7 - Extras - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=extras
baseurl=http://mirrors.163.com/centos/7/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7


#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$7 - Plus - 163.com
baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
           

第四步：執行指令

yum clear all

yum list
           

好了，到這裡就可用了。附上我在公司Redhat安裝執行的指令
