Cause Analysis:

GPG keys are the keys generated when the installation package is released, and the installation needs to check the keys to ensure security

Solution:

1. You can try this first:

 sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

2. Then execute:

yum install mysql-community-server

3. If not, you can use this:

sudo yum -y install * --nogpgcheck

Precautions:

If the above operations still cannot solve the problem, it is recommended to uninstall all SQL-related modules and all their folders, then re-select the SQL meta-download address, and reinstall SQL.

[I have encountered this situation and successfully dealt with it, so I will summarize it. 】
