Ubuntu 安装yum命令 并配置yum源

20220613更新

在Ubuntu使用yum install 安装时候自动升级了系统的一些组件导致系统瘫痪，Ubuntu正确配置和使用yum的方法待更新

直接使用

sudo apt install yum

是可以安装成功，但是这个yum没有配置源，是不能正常安装软件的

创建配置目录

sudo mkdir /etc/yum.repos.d

创建配置源

这里使用的配置版本是CentOS-7.9.2009的源

sudo vi /etc/yum.repos.d/CentOS-Base.repo

输入

# 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.
#
