Centos7已于2024年6月30日结束，我的这个Centos7主要是用来BT下载，没有什么重要的内容，如果你有更加重要的数据，一定要提前进行备份。
如果你要升级到Rocky Linux9，也需要先跟新到Rocky Linux8然后再升级到Rocky Linux9，不能越级升级
准备
Centos7由于已经结束了生命周期，因此需要自己更换yum源
# 备份
cd /etc/yum.repos.d/
mkdir repo_bak
mv *.repo repo_bak/
# 下载Centos7的repo文件
wget http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
# 安装epel源
yum install -y epel-release更新Centos 7
更新并查看当前系统版本
[root@localhost ~]# yum update -y
[root@localhost ~]# neofetch
.. root@localhost.localdomain
