在Linux中,你可以使用`mysql_secure_installation`工具来安全地更改MySQL的初始root用户密码。以下是一个简单的Shell脚本示例,它会引导用户执行这个过程:
```bash
#!/bin/bash
# 检查是否安装了mysql_secure_installation
if ! command -v mysql_secure_installation &> /dev/null; then
echo "mysql_secure_installation not found. Please install MySQL first."
exit 1
fi
echo "Setting up MySQL root user..."
read -p "Enter current password for root (press Enter if blank): " old_password
echo "" # 空行防止回显
# 运行mysql_secure_installation并设置新的密码
mysql_secure_installation --password="linu0224"
echo "Root password has been changed to 'linu0224'. Remember to update your scripts and configurations accordingly."
# 提示用户重启MySQL服务以应用新密码
echo "Please restart the MySQL service for the changes to take effect:"
echo "sudo systemctl restart mysql"
echo ""
echo "Don't forget to secure your production environment with proper permissions and access control!"
```
注意:这个脚本假设你有权限运行`mysql_secure_installation`和管理MySQL服务。如果你是初次接触此脚本,请谨慎操作,因为错误的输入可能导致数据丢失或其他问题。
