Two: The mirror station provides a replacement method, directly copy and replace.

Note: There will be format problems with the copy command here. It is recommended to go directly to the mirror station to copy and modify. It can be used.

When replacing, you need to modify the last line according to the actual file of your system. The file in my /etc/yum.repos.d/ directory is the rocky.repo file, so the last line needs to be modified to rocky*.repo (using the original Rocky-*.repo will result in an error)

sed -e 's|^mirrorlist=|#mirrorlist=|g' \
    -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.sjtug.
sjtu.edu.cn/rocky|g' \
    -i.bak \
    /etc/yum.repos.d/rocky*.repo

Three: Clear cache

yum clean all

Four: Generate a new cache

yum makecache

Five: Upgrade software (optional)

yum -y update
