一、修改.bashrc

修改~/.bashrc，添加以下内容「注意修改」

• 端口号改成自己自定义的端口

alias setproxy='
    export ALL_PROXY="socks5://127.0.0.1:10808"
    export all_proxy="socks5://127.0.0.1:10808"
    echo -e "Acquire::http::Proxy \"http://127.0.0.1:10809\";" | sudo tee -a /etc/apt/apt.conf > /dev/null
    echo -e "Acquire::https::Proxy \"http://127.0.0.1:10809\";" | sudo tee -a /etc/apt/apt.conf > /dev/null
    curl https://ip.gs
'
alias unproxy='
    unset ALL_PROXY;
    unset all_proxy;
    sudo sed -i -e '/Acquire::http::Proxy/d' /etc/apt/apt.conf
    sudo sed -i -e '/Acquire::https::Proxy/d' /etc/apt/apt.conf
    curl https://ip.gs
'

二、设置代理

保存之后 -> 更新.bashrc -> 设置代理 -> 查看代理信息

source ~/.bashrc
setproxy
# 查看export中代理信息，查看proxy.conf中代理信息
export
cat /etc/apt/apt.conf

三、测试代理

# 测试一下代理ip，测试一下代理apt更新
curl ip.sb
sudo apt update

四、更新代理

# 重启就更新一下
unproxy
setproxy
