   Warning: native mysql package from platform vendor seems to be enabled.
    Please consider to disable this before installing packages from repo.mysql.com.
    Run: yum module -y disable mysql
##禁用原有库
yum module -y disable mysql

在禁用原生 MySQL 模块后，确认 MySQL 8.4 社区版存储库已启用。你可以通过以下命令查看可用的存储库：
yum repolist all | grep mysql

yum-config-manager --enable mysql84-community

yum install mysql-community-server

输入：grep 'temporary password' /var/log/mysqld.log

shell > mysql_secure_installation


根据提示完成以下操作：
输入临时 root 密码
设置新的 root 密码
移除匿名用户
禁止 root 远程登录
移除测试数据库
重新加载权限表

修改密码：ALTER USER 'root'@'localhost' IDENTIFIED BY 'tMKmf3fdggim!vfdv1';
查看密码策略：SHOW VARIABLES LIKE 'validate_password%';
修改密码长度：set global validate_password.length=1;（长度）
修改密码等级：set global validate_password.policy=0;（等级）
