### 0x00 前言简述

Q: 操作系统的全局代理?

> 答：我们常常听说网络代理例如 Socket、Http 代理，全局代理即系统所有的流量都是通过该代理通道进行通信, 然而这个还不能说是全称走代理，只能说是 90% 的应用都可以使用这个设置来实现代理访问，但这个只是针对于个别软件由于他们更不都不走 http 协议，所有代理的方式不是绝对的，只有网关流量代理是完全代理的;

Q: 网上关于 Linux 中 http_proxy 的设置说明错误

> 答: Linux 操作系统全局代理配置主要在于环境变量的设置 http_proxy 该变量是支持 http 以及 socket 的; 比如 curl、git 软件默认使用 http_proxy 这个环境变量来设置代理[服务器](https://clou

# WSL 配置

- ## wsl 如何设置 Linux 子系统默认用户为 root
  解决：
1. `WIN` + `R`，输入`cmd`打开命令行窗口
2. 输入命令: `cd %HOMEPATH%\AppData\Local\Microsoft\WindowsApps`，查看安装的子系统对应的应用名，比如：`ubuntu2404.exe`
3. 输入命令：`.\ubuntu2404.exe config --default-user root`
4. 再次打开子系统会发现已经默认登录用户为root了

- ## wsl 如何设置 Linux 子系统默认用户为 root
解决：
1. 输入命令：`wsl -l --all`查看所有版本
2. 命令格式：`wsl --setdefault wsl名称`，例如：`wsl --setdefault Ubuntu-24.04`将Ubuntu-24.04设置为默认子系统
