Red Hat Enterprise Linux 7.3更換CentOS 7 yum源

2020-06-16 16:41:02

RedHat yum源是收費的,沒有註冊的Redhat機器是不能使用yum源的。

1、當前系統環境:

系統版本:Red Hat Enterprise Linux Server release 7.3 (Maipo)

軟體環境:系統預設是自帶了yum程式的,需要解除安裝,安裝CentOS

2、更換yum源:

1) 解除安裝本地yum:

# rpm -qa|grep yum      #檢視本地yum

 

# rpm -qa|grep yum|xargs rpm -e --nodeps       #解除安裝本地yum,不檢查依賴性,解除安裝yum程式

# rpm -qa | grep Python-urlgrabber | xargs rpm -e --nodeps   

2) 下載CentOS yum程式

#  wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-161.el7.centos.noarch.rpm     

#  wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-50.el7.noarch.rpm     

#  wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm     

使用wget命令下載,也可以用瀏覽器下載。rpm包下載地址http://mirrors.163.com/centos/7/os/x86_64/Packages/ ,包的版本會有更新,選擇最新版本下載

安裝CentOS yum程式

為避免他們之間互相依賴,三個程式一起安裝

# rpm -ivh yum-3.4.3-161.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-50.el7.noarch.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm   

 

安裝報錯,依賴軟體版本不相容,

3) repo 組態檔

下載組態檔

#  cd /etc/yum.repos.d/  #進入到yum組態檔目錄

#  wget http://mirrors.163.com/.help/CentOS7-Base-163.repo    #下載組態檔

設定組態檔

# sed -i "s;$releasever;7;g" CentOS7-Base-163.repo   

替換新的repo檔案

# mv redhat.repo redhat.repo.bak   

組態檔內容如下:

[base]

更新yum快取

# yum clean all  #清除yum快取

 

# yum makecache    #更新yum快取

 

執行yumrepolist檢視,如果顯示出repo倉庫列表並顯示軟體包數量則OK。

#  yum  repolist   

 

至此yum源更換完成。
