https://en.wikipedia.org/wiki/Proxy_auto-config 根据给定访问地址，自动选择代理服务器

~/.config/pip/pip.conf

[global]
proxy=http://localhost:1087

注意不支持socks5

refer https://pip.pypa.io/en/stable/user_guide/#using-a-proxy-server

1. Clone with ssh

   在文件 ~/.ssh/config 后添加下面两行：

   1Host github.com
   2# Mac下
   3ProxyCommand nc -X 5 -x 127.0.0.1:1080 %h %p
   4# Linux下
   5ProxyCommand nc --proxy-type socks5 --proxy 127.0.0.1:1080 %h %p

   注意 Linux 和 Mac 下 ncat/netcat 区别，详见 https://unix.stackexchange.com/q/368155

2. Clone with http

   1git config --global http.proxy http://127.0.0.1:1087

   建议使用 http，因为 Socks5 在使用 git-lfs 时会报错 proxyconnect tcp: dial tcp: lookup socks5: no such host

Cargo 会依次检查以下位置

1. 环境变量 CARGO_HTTP_PROXY

1export CARGO_HTTP_PROXY=http://127.0.0.1:1080

1. 任意 config.toml 中的 http.proxy

1[http]
2proxy = "127.0.0.1:1080"

1. 环境变量 HTTPS_PROXY & https_proxy & http_proxy

1export https_proxy=http://127.0.0.1:1080
2export http_proxy=http://127.0.0.1:1080

http_proxy 一般来讲没必要，除非使用基于 HTTP 的 Crate Repository

Cargo 使用 libcurl，故可接受任何符合 libcurl format 的地址与协议

( 127.0.0.1:1080 , http://127.0.0.1:1080 , socks5://127.0.0.1:1080 ）均可

refer https://doc.rust-lang.org/cargo/reference/config.html#httpproxy

在 /etc/apt/apt.conf.d/ 目录下新增 proxy.conf 文件，加入：

Acquire::http::Proxy "http://127.0.0.1:8080/";
Acquire::https::Proxy "http://127.0.0.1:8080/";

注：无法使用 Socks5 代理。

add to ~/.curlrc

1HTTP_PROXY=socks5://localhost:1080 go get

测试了下 HTTPS_PROXY 和 ALL_PROXY 都不起作用

OR 使用goproxy.io

1npm config set proxy http://127.0.0.1:1087
2npm config set https-proxy http://127.0.0.1:1087

用 Socks5 就报错- -

推荐使用 yarn，npm 是真的慢

refer https://stackoverflow.com/q/7559648/12539782

1yarn config set proxy http://XX
2yarn config set https-proxy http://XX

不支持 socks5

1sudo systemctl daemon-reload

必须是 Socks5，http 不生效
