Red Hat Linux 沒法使用yum命令

爲啥不能使用的 主要就是由於redhat自帶的須要註冊才能使用。通俗講就是換成centOS系統的yum庫  。redHat與centOS的版本是對應的，因此只須要知道redHat的版本下載對應的庫就能夠了。

關鍵點：1.要有網

　　　　2.若是出現key ID f4a80eb5: NOKEY 的問題  應該就是版本問題   可能過高或過低

 

備註：其實我util包怎麼也沒裝上  但好像後邊也沒有影響也能使用；關於python ，若是裝了多個版本的python,須要配置指定使用哪一個

 

 

一、爲何RHEL不能使用yum命令
由於它是收費的，因此係統須要先註冊。
二、解決方案：使用centOS系統的yum庫
2.一、保證電腦能上網

2.二、清除原有RHEL的與yum相關軟件包.

$rpm -qa | grep yum | xargs rpm -e --nodeps
$rpm -qa | grep python-urlgrabber|xargs rpm -e --nodeps

2.三、查找與當前系統匹配的centOS系統版本
　　163的鏡像庫 （推薦）：　
　　 http://mirrors.163.com/centos/7/os/x86_64/Packages/
　　kernel鏡像庫：　
　　 https://mirrors.edge.kernel.org/centos/7/os/x86_64/Packages/

2.四、 下載python相關的rpm包並安裝

$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/python-urlgrabber-3.10-8.el7.noarch.rpm

$rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
$rpm -ivh python-urlgrabber-3.10-8.el7.noarch.rpm

2.五、 下載yum相關的rpm包並安裝
此處若是直接用CentOS 7的包的話，會出現如下問題：

$wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-150.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-utils-1.1.31-40.el7.noarch.rpm
$wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-40.el7.noarch.rpm
$wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

$ls
anaconda-ks.cfg yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm
initial-setup-ks.cfg yum-updateonboot-1.1.31-40.el7.noarch.rpm
yum-3.4.3-150.el7.centos.noarch.rpm yum-utils-1.1.31-40.el7.noarch.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

$rpm -ivh yum-*
warning: yum-3.4.3-150.el7.centos.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
error: Failed dependencies:
python-urlgrabber >= 3.10-8 is needed by yum-3.4.3-150.el7.centos.noarch

解決方法是：去http://rpm.pbone.net/下載相對較低版本的rpm包。

$wget ftp://ftp.icm.edu.pl/vol/rzm3/linux-centos-vault/7.1.1503/cr/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
$wget ftp://ftp.icm.edu.pl/vol/rzm3/linux-centos-vault/7.1.1503/cr/x86_64/Packages/yum-3.4.3-132.el7.centos.noarch.rpm
$wget ftp://ftp.icm.edu.pl/vol/rzm3/linux-centos-vault/7.3.1611/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
$wget ftp://ftp.icm.edu.pl/vol/rzm3/linux-centos-vault/7.1.1503/cr/x86_64/Packages/yum-updateonboot-1.1.31-34.el7.noarch.rpm
$wget ftp://ftp.icm.edu.pl/vol/rzm3/linux-centos-vault/7.1.1503/cr/x86_64/Packages/yum-utils-1.1.31-34.el7.noarch.rpm
$rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
$rpm -ivh yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm yum-3.4.3-132.el7.centos.noarch.rpm
$rpm -ivh yum-utils-1.1.31-34.el7.noarch.rpm
$rpm -ivh yum-updateonboot-1.1.31-34.el7.noarch.rpm

必須按上面順序安裝這五個包，否則會報包依賴相關的錯，並且yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm和yum-3.4.3-132.el7.centos.noarch.rpm必須同時安裝。
若是上面下載包的連接失效了，能夠到http://rpm.pbone.net/中搜索並使用其餘的下載連接：

 

2.六、 新建repo 配置文件；

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

在改文件中寫入以下內容：

#CentOS-Base.repo
[base]
name=CentOS-$7 - Base - 163.com

baseurl=http://mirrors.163.com/centos/7/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

[updates]
name=CentOS-$7 - Updates - 163.com

baseurl=http://mirrors.163.com/centos/7/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

[extras]
name=CentOS-$7 - Extras - 163.com

baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

[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

2.七、清除緩存：

$yum clean all
Loaded plugins: fastestmirror, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Cleaning repos: base extras updates
Cleaning up everything

2.八、測試安裝是否正常；

$yum -y install docker原文連接：https://blog.csdn.net/nudtfeizhang/article/details/83689808
