设置Ubuntu网络代理

设置Ubuntu网络代理

1 编写set_proxy.sh

在/home/xxx新建文件set_proxy.sh，添加如下代码：

#!/bin/sh
hostip=$(cat /etc/resolv.conf | grep nameserver | awk '{ print $2 }')
wslip=$(hostname -I | awk '{print $1}')
port=10809

PROXY_HTTP="http://${hostip}:${port}"

set_proxy(){
    export http_proxy="${PROXY_HTTP}"
    export HTTP_PROXY="${PROXY_HTTP}"

    export https_proxy="${PROXY_HTTP}"
    export HTTPS_proxy="${PROXY_HTTP}"
}

unset_proxy(){
    unset http_proxy
    unset HTTP_PROXY
    unset https_proxy
    unset HTTPS_PROXY
}

test_setting(){
    echo "Host ip:" ${hostip}
    echo "WSL ip:" ${wslip}
    echo "Current proxy:" $https_proxy
}

if [ "$1" = "set" ]
then
    set_proxy

elif [ "$1" = "unset" ]
then
    unset_proxy

elif [ "$1" = "test" ]
then
    test_setting
else
    echo "Unsupported arguments."
fi

2 修改配置文件（例如.bashrc）

在.bashrc文件中增加两行：

alias proxy="source /home/xxx/set_proxy.sh"
. /home/xxx/set_proxy.sh set
