一、linux 代理全局设置
export http_proxy=http://192.168.6.9:8080/
export https_proxy=https://192.168.6.9:8080/ 可以
export https_proxy=http://192.168.6.9:8080/ 也可以
缺点，有些工具不生效，每次要取消代理设置也麻烦
二、linux 命令行临时设置代理，推荐
apt
http proxy
sudo apt -o Acquire::http::proxy="192.168.6.9:8080/" install gcc
sudo apt -o Acquire::http::proxy="http://192.168.6.9:8080/" install gcc
https proxy
sudo apt -o Acquire::https::proxy="https://192.168.6.9:8080/" install gcc
SOCKS proxy
sudo apt -o Acquire::http::proxy="socks5h://192.168.6.9:8080/" install gcc
sudo apt -o Acquire::https::proxy="socks5h://192.168.6.9:8080/" install gcc
curl
curl -x http://192.168.6.9:8080 http://www.google.com
curl -x socks5h://192.168.6.9:8080 http://www.google.com
curl -k --proxy socks5h://192.168.6.9:8080 http://www.google.com
-x, --proxy [protocol://]host[:port] Use this proxy
-k, --insecure Allow insecure server connections when using SSL
wget
wget -e use_proxy=yes -e http_proxy=http://192.168.6.9:8080 https://www.google.com
wget --no-check-certificate -e use_proxy=yes -e https_proxy=https://192.168.6.9:8080 https://www.google.com
wget不支持SOCKS代理,如下不行
wget -e "http_proxy=socks5h://localhost:2000" https://google.com
wget -e "https_proxy=socks5h://localhost:2000" https://google.com
git
export http_proxy=http://192.168.6.9:8080/
export https_proxy=http://192.168.6.9:8080/ 可以
export https_proxy=https://192.168.6.9:8080/ 也可以
这样设置，git clone概率错误，需要git config https.proxy或者git config --global https.proxy
git config http.proxy 'http://192.168.6.9:8080'
git config https.proxy 'https://192.168.6.9:8080'
git config --global http.proxy 'http://192.168.6.9:8080'
git config --global https.proxy 'https://192.168.6.9:8080'
推荐下面三个
git -c http.proxy='http://192.168.6.9:8080' -c https.proxy='https://192.168.6.9:8080' clone
git -c http.proxy='socks5://192.168.6.9:8080' -c https.proxy='socks5://192.168.6.9:8080' clone
git -c http.proxy='socks5h://192.168.6.9:8080' -c https.proxy='socks5h://192.168.6.9:8080' clone
