sudo dnf install @mysql
sudo systemctl enable --now mysqld
sudo systemctl status mysqld
如果显示：
mysqld.service - MySQL 8.0 database server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2019-10-17 22:09:39 UTC; 15s ago
则证明安装成功。
