# 科学上网-让终端走代理

## 介绍

在终端环境下，常会遇到要下载某个文件巨慢，甚至无法连接,急需一个方案来拯救.

## 过程

1. 临时

   ```shell
   # 协议填http或socks5
   export http_proxy=http://127.0.0.1:10809
   export https_proxy=https://127.0.0.1:10809
   export http_proxy=socks5://127.0.0.1:10808
   export https_proxy=socks5://127.0.0.1:10808
   # 让环境生效
   source /etc/profile
   # ping是ICMP报文，代理不转发
   # 检查终端是否处于代理状态
   curl cip.cc
   # 针对codex 登录1455可以如上配置
   # 配置后需要新开终端运行 codex login登录,获取到auth.json后，下次插件和终端就都可以使用了
   ```
2. 或使用 `alias`

   ```shell
   alias setproxy='export ALL_PROXY=socks5://127.0.0.1:10808'
   alias unsetproxy='unset ALL_PROXY'
   ```
3. `ssh`走代理 新增 `~/.ssh/config` ::: code-group

   ```shell
   # github socks5 
   Host github.com
       HostName github.com
       User git
       Port 22
       IdentityFile ~/.ssh/id_ed25519
       ProxyCommand nc -v -x 127.0.0.1:10808 %h %p

   # github http
   Host github.com
       HostName github.com
       User git
       Port 22
       IdentityFile ~/.ssh/id_ed25519
       ProxyCommand corkscrew 127.0.0.1:10809 %h %p
   # linux需要单独安装 `corkscrew`
   # sudo apt install corkscrew
   ```

   ```shell
   # 测试 SSH 连接（看到下面提示说明成功）
   ssh -T git@github.com
   # 成功提示：
   # Hi 用户名! You've successfully authenticated, but GitHub does not provide shell access.

   git clone --depth 1 https://github.com/用户名/项目名.git
   ```

   ::: code-group
4. `curl`走代理 新增 `~/.curlrc`

   ```shell
   proxy = http://127.0.0.1:10809
   ```

## 在windows WSL中配置代理

```shell
# 查找本机ip 最后的nameserver就是ip
cat /etc/resolv.conf
# 协议填http或sock
export http_proxy="http://ip:port"
export https_proxy="http://ip:port"
# 让环境生效
source /etc/profile
```

## 在windows CMD中配置代理

```shell
# 协议填http
set http_proxy=http://127.0.0.1:10809
set https_proxy=http://127.0.0.1:10809

# ps:一定要用cmd命令行，千万别用powershell !!!
# 简易测试命令：curl https://www.google.com（别用ping）
```
