1. Ubuntu 22.04 LTS Desktop 安装准备Ubuntu 22.04.1 LTSJammy Jellyfish作为长期支持版本提供了5年的标准维护周期。对于开发者而言选择LTS版本意味着更稳定的软件生态和持续的安全更新。在开始安装前需要做好以下准备工作首先确认硬件兼容性。虽然Ubuntu对硬件要求不高但为了流畅运行现代开发环境建议配置至少Intel i5或同级AMD处理器、8GB内存和256GB SSD存储空间。特别要注意的是如果使用NVIDIA显卡建议提前准备好闭源驱动安装方案因为开源Nouveau驱动在部分型号上可能存在性能问题。下载官方ISO镜像时推荐通过Ubuntu官网或国内镜像站获取。国内用户可以选择阿里云镜像https://mirrors.aliyun.com/ubuntu-releases/22.04/或清华镜像站https://mirrors.tuna.tsinghua.edu.cn/ubuntu-releases/22.04/下载速度会快很多。务必校验SHA256哈希值确保镜像完整性。制作启动盘时建议使用Ventoy这类多系统启动工具它允许直接将ISO文件拷贝到U盘而无需反复格式化。对于传统BIOS启动的旧设备可能需要禁用Secure Boot而UEFI设备则建议开启Secure Boot以获得更好的安全性。重要提示安装前备份重要数据特别是准备进行全盘安装或双系统配置时误操作可能导致数据丢失。可以使用Clonezilla等工具先创建完整磁盘映像。2. 系统安装与基础配置安装过程本身相对简单但有几个关键选择会影响后续使用体验。在分区方案上对于SSD设备建议采用以下结构EFI分区300MBFAT32交换分区内存大小的1.5倍如果内存≥16GB可不设/根分区至少50GBext4/home分区剩余空间ext4这种分离方案使得系统重装时能够保留用户数据。安装类型选择最小化安装可以减少不必要的软件包后期再按需添加组件。安装完成后首先执行系统更新sudo apt update sudo apt upgrade -y sudo apt install -y ubuntu-restricted-extras网络配置方面如果使用有线连接NetworkManager通常能自动识别。对于WiFi可能需要安装额外固件sudo apt install -y firmware-iwlwifi时区设置建议启用自动同步sudo timedatectl set-ntp true3. 开发环境搭建3.1 编程语言支持对于Java开发推荐安装JDK 21 LTS版本sudo apt install -y openjdk-21-jdk配置JAVA_HOME环境变量echo export JAVA_HOME/usr/lib/jvm/java-21-openjdk-amd64 ~/.bashrc source
