Debian的基本使用

前言

本人撰写的相关文档中，部分技术已经不再提供支持了（不得不感慨，菜鸡的个人进步追不上技术更新啊），比如Centos、EasyExcel，虽然说目前仅使用还没有什么问题，但是还是要了解一下备用方案。

Centos已经不再维护了，需要考虑使用其他系统，如Debian等，本次就先对Debian进行一下了解。国产化的如龙蜥、麒麟等也发展的很不错，也可以作为后续了解的方向。

需要说明的是，本人水平有限，理论知识就不班门弄斧了，大家可以自行在网上搜索，本次仅安装配置一些之前运行在centos上的软件，如git、maven等。

Debian安装配置JDK17

查看Debian版本

root@iZuf67owyzd0wopzvdfgsyZ:/# cat /etc/debian_version
12.7

安装jdk

12版本是可以直接安装jdk17的，如果想安装其他版本，可以使用wget的形式

先更新软件包信息

apt update

其实总体的流程和在centos上进行安装配置是比较类似的，就是部分命令不一样
