以下是执行 mysql_secure_installation 的详细步骤，帮助您安全配置 MySQL 服务器：
打开终端，执行以下命令以启动 MySQL 安全配置工具：
sudo mysql_secure_installation
如果这是第一次设置密码，MySQL root 用户没有密码，您可以直接按 Enter 键。否则，请输入当前的 root 密码。
脚本会提示您是否要设置新的 root 密码。建议设置一个强密码以提高安全性。输入 Y 并按 Enter，然后按照提示设置您的新密码。
匿名用户允许任何人登录 MySQL，这通常用于测试。请执行以下操作以删除匿名用户：
Y
按 Enter 确认操作。
为了提升安全性，建议禁止 root 用户从远程设备登录。执行以下操作：
Y
按 Enter 确认。
默认安装的 test 数据库允许任何用户访问，建议在生产环境中删除它。执行以下操作：
Y
按 Enter 确认。
所有更改将立即生效，您需要重新加载权限表：
Y
按 Enter 确认。
以下是完整示例输出，供参考：
Securing the MySQL server deployment.Enter password for user root: (输入当前的 root 密码或直接按 Enter 如果没有密码)The existing password for the user account root has expired. Please set a new password.New password: (输入新的 root 密码)Re-enter new password: (重新输入新的 root 密码)VALIDATE PASSWORD PLUGIN 可以用于测试密码并提高安全性。它检查密码的强度，并确保用户只能设置安全强的密码。Would you like to setup VALIDATE PASSWORD pluginPress y|Y for Yes, any other key for No: Y (根据需要选择是否启用密码验证插件)Please set the password validation policy:LOW Length >= 8MEDIUM Length >= 8, numeric, mixed case, and special charactersSTRONG Length >= 8, numeric, mixed case, special characters and dictionary filePlease enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 (选择密码验证策略)Using existing password for root.Estimated strength of the password: 100Change the password for root ((Press y|Y for Yes, any other key for No) : N (如果刚刚设置了密码，这里选择 N)... skipping.By default, a MySQL installation has an anonymous user, allowing anyoneto log into MySQL without having to have a user account created forthem. This is intended only for testing, and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.Remove anonymous users (Press y|Y for Yes, any other key for No) : Y (删除匿名用户)Success.Normally, root should only be allowed to connect from ‘localhost’. Thisensures 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 (禁止 root 用户远程登录)Success.By default, MySQL comes with a database named ‘test’ that anyone canaccess. This is also intended only for testing, and should be removedbefore moving into a production environment.Remove test database and access to it (Press y|Y for Yes, any other key for No) : Y (删除测试数据库)Dropping test database…Success.Removing privileges on test database…Success.Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now (Press y|Y for Yes, any other key for No) : Y (重新加载权限表)Success.All done!你已经成功执行了 mysql_secure_installation，并提高了 MySQL 服务器的安全性。
