centOS8停止维护后，yum无法正常安装应用的问题处理 （阿里云服务器扩容时遇到的问题）

问题描述：CentOS8安装growpart时，报404错误，导致后续操作无法执行。

 

 

 

操作流程 

1.备份原有yum源配置:

cd /etc/yum.repos.d/  
mkdir bak 
mv * bak

2.在/etc/yum.repos.d目录下新建CentOS-Base.repo文件:

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

3.在/etc/yum.repos.d/CentOS-Base.repo文件中编辑以下内容:

# 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.
#

4.更新yum:

yum clean all
yum makecache

5.再次尝试安装growpart

 

6.后续磁盘扩容操作

growpart /dev/vda 1

xfs_growfs /dev/vda1(meta-data值)
