(1)如何在J1900小型电脑上安装Ubuntu服务器：全面指南
--------------------------------------------------中文---------------------------------------------
Ubuntu服务器是一款流行的服务器操作系统，以其稳定性、安全性和可扩展性而闻名，是网站服务器、电子邮件服务器和其他类型的服务器的理想选择。在这篇文章中，我们将提供一份详细指南，介绍如何在J1900小型电脑上安装Ubuntu服务器，并在安装过程中提醒需要注意的一些重要事项。
第一步：准备引导U盘
在J1900 Mini PC上安装Ubuntu服务器的第一步是准备一个可以引导的U盘。您可以从官方网站上下载Ubuntu Server ISO文件，并使用Rufus或Etcher这样的工具将ISO文件写入U盘中。
第二步：进入BIOS设置
在J1900 Mini PC上安装Ubuntu服务器之前，需要进入BIOS设置并更改引导顺序，以便从U盘启动。要做到这一点，请重新启动您的小型电脑，并按下进入BIOS设置所需的按键。这个按键可能因您的计算机型号而异，但通常是F2或Del键。
第三步：从U盘启动
一旦进入BIOS设置，导航到启动选项卡，并确保将U盘列为第一启动设备。保存并退出BIOS设置。现在您的计算机将从U盘启动。
第四步：安装Ubuntu服务器
接下来，您将看到Ubuntu服务器安装界面。选择您喜欢的语言，然后选择“安装Ubuntu服务器”选项。
第五步：配置安装参数
在安装过程中，您需要配置一些参数，例如系统语言、时区、键盘布局和网络设置。根据您的要求设置这些参数。
第六步：创建交换分区
如前所述，J1900 Mini PC通常具有有限内存。因此，在安装过程中创建交换分区非常重要。交换分区是一种虚拟内存空间，可使系统在运行占用大量内存的应用程序时调整内存使用情况。推荐的做法是将交换分区大小设置为物理内存的两倍。例如，如果您的小型电脑有2GB的RAM，则应创建4GB的交换分区。
第七步：创建分区
接下来，您需要创建分区。Ubuntu服务器允许您手动或自动创建和管理磁盘分区。对于J1900 Mini PC，建议手动创建分区，以便根据您的特定要求分配资源。创建分区后，请指定挂载点。
第八步：安装Grub引导程序
安装完成之后，将要求您安装引导程序。此处应选择安装Grub引导程序，因为它是Ubuntu服务器默认的引导程序。
第九步：重启系统
完成安装后，您需要拔掉U盘并重新启动系统。您的J1900 Mini PC现在应该能够启动进入Ubuntu服务器了。
第十步：更新和保护
安装Ubuntu服务器之后，建议更新软件包，以确保您拥有最新的安全性和稳定性更新。您可以运行以下命令来更新软件包：
sudo apt update
sudo apt upgrade
此外，建议配置防火墙并禁用无关的服务。还可以更改默认的SSH端口以提高安全性。
结论：
Ubuntu服务器是一个功能强大、稳定且可扩展的操作系统，可用于提高J1900 Mini PC的性能和功能。按照上述步骤，您可以轻松安装Ubuntu服务器并根据您的特定需求进行优化。此外，我们还强调了在安装过程中需要注意的一些重要事项，例如创建交换分区、配置分区和保护系统。这些最佳实践将确保您的服务器稳定、安全，并针对性地优化性能和可扩展性。
总之，安装Ubuntu服务器并进行优化，能够使J1900 Mini PC更加适应您的工作需求，也可以为您提供更加稳定的工作环境和更为出色的工作表现。希望这篇文章能为您提供有用的指南并帮助您成功安装Ubuntu服务器。

How to Install Ubuntu Server on a J1900 Mini PC: A Comprehensive Guide
Ubuntu Server is a popular server operating system renowned for its stability, security, and scalability, making it an ideal choice for web servers, email servers, and other types of servers. In this article, we will provide a detailed guide on how to install Ubuntu Server on a J1900 Mini PC and highlight important things to keep in mind during the installation process.
Step 1: Prepare a Bootable USB Drive
The first step to installing Ubuntu Server on a J1900 Mini PC is to prepare a bootable USB drive. You can download the Ubuntu Server ISO file from the official website and use tools like Rufus or Etcher to write the ISO file to the USB drive.
Step 2: Enter BIOS Settings
Before installing Ubuntu Server on a J1900 Mini PC, you need to enter BIOS settings and change the boot order to boot from the USB drive. To do this, restart your mini PC and press the key required to enter BIOS settings. This key may vary depending on your computer model, but it is usually the F2 or Del key.
Step 3: Boot from USB Drive
Once you enter BIOS settings, navigate to the boot options tab and ensure that the USB drive is listed as the first boot device. Save and exit BIOS settings. Your computer will now boot from the USB drive.

Step 6: Create a Swap Partition
As mentioned earlier, J1900 Mini PCs typically have limited RAM. Therefore, creating a swap partition during the installation process is essential. A swap partition is a virtual memory space that allows the system to adjust memory usage when running memory-intensive applications. The recommended practice is to set the swap partition size to twice the physical memory. For example, if your mini PC has 2GB of RAM, you should create a 4GB swap partition.
Step 7: Create Partitions
Next, you need to create partitions. Ubuntu Server allows you to manually or automatically create and manage disk partitions. For J1900 Mini PCs, it is recommended to manually create partitions so that resources can be allocated according to your specific requirements. After creating partitions, specify the mount point.
Step 8: Install Grub Bootloader
After installation, you will be prompted to install the bootloader. Choose to install the Grub bootloader, as it is the default bootloader for Ubuntu Server.
Step 9: Reboot the System
After the installation is complete, remove the USB drive and reboot the system. Your J1900 Mini PC should now boot into Ubuntu Server.
Step 10: Update and Protect
After installing Ubuntu Server, it is recommended to update the packages to ensure that you have the latest security and stability updates. You can run the following commands to update the packages:
sudo apt update
sudo apt upgrade
In addition, it is recommended to configure the firewall and disable unnecessary services. You can also change the default SSH port to improve security.
Conclusion:
Ubuntu Server is a powerful, stable, and scalable operating system that can enhance the performance and functionality of a J1900 Mini PC. By following the above steps, you can easily install Ubuntu Server and optimize it according to your specific requirements. Furthermore, we have highlighted some important things to keep in mind during the installation process, such as creating a swap partition, configuring partitions, and protecting the system. These best practices will ensure that your server is stable, secure, and optimized for performance and scalability.
In summary, installing and optimizing Ubuntu Server can make J1900 Mini PCs more suitable for your work requirements and provide a more stable and outstanding work environment and performance. We hope this article provides you with a useful guide and helps you successfully install Ubuntu Server.
