如何在 Fedora 上重新安裝 mysql/mysqld？

我遇到了一些mysqld無法啟動的問題，因此我想清除或（至少）重新安裝其文件，以便用庫存文件替換目前配置文件，以便重新啟動。

這是的內容journalctl -xeu mysqld.service：

我正在使用 Fedora 36 並安裝了以下軟體包

mysql80-community-release-fc36-1.noarch
mysql-community-common-8.0.30-10.fc36.x86_64
mysql-community-client-plugins-8.0.30-10.fc36.x86_64
mysql-community-libs-8.0.30-10.fc36.x86_64
mysql-community-client-8.0.30-10.fc36.x86_64
mysql-community-icu-data-files-8.0.30-10.fc36.x86_64
mysql-community-server-8.0.30-10.fc36.x86_64
mysql-workbench-community-8.0.30-1.fc36.x86_64

使用MySQL 的網站。

問題是我想解除安裝它，但它想刪除太多依賴項，如果這意味著它們已損壞，Fedora 不允許安裝依賴項。

sudo systemctl stop mysqld # not sure it's called this way
sudo rm -rf /var/lib/mysql # this will wipe out all the data inside the database - @toppk
sudo dnf reinstall mysql-community-server
