RedHat Linux7.3 使用yum安裝時報錯，改用CentOS yum源

在使用redhat linux的yum來安裝或者更新軟件的時候會有以下提示：

[root@node1 home]# yum install package_name Loaded plugins: product-id, security, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Setting up Install Process Nothing to do

通過翻譯是沒有通過註冊的，查閱資料發現redhat的yum在線更新是收費的，若是沒有註冊的話不能使用，若是要使用，需將redhat的yum卸載後，重啓安裝，再配置其餘源

解決辦法：

• 首先到http://mirrors.163.com/centos下載軟件包，本次爲最新版本 x86_64 地址：http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/ 必要下載的軟件包有（以64位系統爲例）：
• 1.1.python-iniparse-0.4-9.el7.noarch.rpm
• 1.2.python-urlgrabber-3.10-8.el7.noarch.rpm
• 1.3.yum-3.4.3-150.el7.centos.noarch.rpm
• 1.4.yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
• 1.5.yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

下載命令：

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

 卸載RedHat自帶的yum

1>   xargs是一條Unix和類Unix操做系統的經常使用命令。它的做用是將參數列表轉換成小塊分段傳遞給其餘命令，以免參數列表過長的問題

2>   –nodeps  強制卸載,無論依賴性

rpm -qa | grep yum | xargs rpm -e --nodeps

 卸載RedHat自帶的兩個python：

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

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

安裝下載的centos的yum包：

最後2個須要一塊兒安裝，不然會出現依賴性錯誤

rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh python-urlgrabber-3.10-8.el7.noarch.rpm rpm -ivh yum-3.4.3-150.el7.centos.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

到http://mirrors.163.com的 centos幫助文檔 中下載CentOS6-Base-163.repo文件，存放到/etc/yum.repo.d中：

wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

編輯CentOS7-Base-163.repo文件，將其中的$releasever更改成centos的版本號 下面是修改好的，centos的版本號爲7，可根據http://mirrors.163.com/centos/$releasever
/os/x86_64/repodata/repomd.xml來測試版本號應該是什麼，經測試http://mirrors.163.com/centos/7
/os/x86_64/repodata/repomd.xml是能夠的，而換成7.二、7.3都是不成功的

最後，使用yum命令清除緩存、更新所有安裝包： 

yum clean all 清除原有緩存

yum makecache  獲取yum列表 出現下面提示，表示yum更改完成： Metadata Cache Created/元數據緩存已創建

yum update 更新所有安裝包，看需求，無關緊要。
