- git proxy:
git config --global http.proxy 'http://127.0.0.1:7890' git config --global https.proxy 'http://127.0.0.1:7890' - http/https proxy
export http_proxy="http://127.0.0.1:7890" export https_proxy="http://127.0.0.1:7890" - wget proxy
$ cat ~/.wgetrc https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 ftp_proxy=http://127.0.0.1:7890 no_proxy = 127.0.0.1 use_proxy=on - apt proxy
For console
$ sudo apt-get -o Acquire::http::proxy="http://127.0.0.1:7890" update $ sudo apt-get -o Acquire::http::proxy="http://127.0.0.1:7890" install xxx
For configure file
$ cat /etc/apt/apt.conf.d/proxy.conf
Acquire::http::Proxy "http://127.0.0.1:7890";
Acquire::https::Proxy "http://127.0.0.1:7890";
or
Acquire::http::Proxy "http://username:password@yourproxyaddress:proxyport";
Acquire::https::Proxy "http://username:password@yourproxyaddress:proxyport";
- curl proxy
$ curl -x "http://user:pwd@127.0.0.1:1234" "http://httpbin.org/ip" $ curl --proxy "http://user:pwd@127.0.0.1:1234" "http://httpbin.org/ip" $ curl --socks5 socks5_proxy:port http://www.example.com
3. Rust cargo http proxy configure
$ cat ~/.cargo/config.toml
[http]
proxy="127.0.0.1:7890"
