redhat服務(wù)器更換為centos yum源方式

更新時間：2025年12月05日 08:58:10 作者：仰望星空下的自己

該文章主要介紹了如何在CentOS系統(tǒng)中手動下載和配置Yum源,包括下載Yum源文件、修改CentOS-Base.repo文件、驗(yàn)證更新等步驟

1.卸載原有的yum

# 查看是有安裝了yum
rpm -qa|grep yum
# 卸載原有的yum
rpm -qa|grep yum|xargs rpm -e --nodeps

2.找一個自己喜歡的目錄新建checkYum.sh(文件名隨意)

該文件主要是下載yum源需要的內(nèi)容并且安裝yum

#!/bin/bash
# 7.9.2009 對應(yīng)的centos的版本號
wget http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
rpm -ivh /pkg/yum-*

3.下載響應(yīng)的repo源文件

# 建議先將該目錄下的文件進(jìn)行備份
cd /etc/yum.repos.d/CentOS-Base.repo
# 該命令也可以寫到上一步的文件中一起下載
# 如果寫到文件中可以使用  wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

4.修改CentOS-Base.repo文件內(nèi)容

4.1. 下載后的源文件

# 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-$releasever - Base - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/

4.2. 修改后的文件

將所有的$releasever更改為自己下載.rpm文件對應(yīng)的版本

eg:

我自己：http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-3.4.3-169.el7.centos.noarch.rpm；

我這里下載的是7.9.2009的所以將$releasever更改為7.9.2009，其他的不需要更改

# 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

# remarked out baseurl= line instead.

5.更新

yum clean all && yum makecache

6.查看是否更新成功

yum repolist all

7.以上命令可以完全寫到一個統(tǒng)一shell腳本中

rpm -qa | grep yun | xargs rpm -e --nodeps
wget http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.163.com/centos/7.9.2009/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
rpm -ivh /pkg/yum-*
# 下載repo源文件
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
# 統(tǒng)一將$releasever更改為指定的版本
sed -i "s/\$releasever/7.9.2009/g" /etc/yum.repos.d/CentOS-Base.repo
yum clean all && yum makecache
yum repolist all
