第 1 步。在继续之前，请更新您的 Fedora 操作系统以确保所有现有 软件包都是最新的。使用此命令更新服务器 软件包：
sudo dnf upgrade
sudo dnf update第 2 步。在 Fedora 上 安装 MySQL。
默认情况下，MySQL 软件包不在 Fedora 37 的默认存储库中。现在运行以下命令将 MySQL 存储库添加到您的 Fedora 系统中：
sudo dnf install https://dev.mysql.com/get/mysql80-community-release-fc37-1.noarch.rpm添加 MySQL Yum 仓库后，您可以通过运行以下命令在 Fedora 37 系统上 安装 MySQL：
sudo dnf install mysql-community-server安装完成后，通过运行以下命令启动 MySQL 服务：
sudo systemctl start mysqld
sudo systemctl enable mysqld要验证是否已安装 MySQL，请运行以下命令：
mysql --version第 3 步。保护 MySQL 安装。
MySQL附带了一个脚本，可以帮助您保护安装。若要运行此脚本，请键入以下命令：
sudo mysql_secure_installation此命令将启动MySQL安全 安装向导，该向导将指导您完成保护MySQL服务器的过程。系统将提示您设置 root 密码、删除匿名用户、禁用远程 root 登录以及删除测试数据库。按照提示完成设置。

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Success.
All done!
