1.centos9换成国内阿里源使其下载软件较快。
先查看cnetos9本身的源
cat /etc/yum.repos.d/centos.repo
2.备份系统本身的源
[root@localhost ~]# mv /etc/yum.repos.d/centos.repo /etc/yum.repos.d/centos.repo.backup
3.然后编辑阿里源进去在/etc/yum.repos.d/centos.repo
[root@localhost ~]# vi /etc/yum.repos.d/centos.repo
# 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.

清空缓存
yum makecache
然后在更新软件
