安裝privoxy

# Ubuntu/debian
sudo apt-get install privoxy

# Centos
sudo yum install privoxy

# Mac osx
sudo port install privoxy

修改配置檔案

vi /etc/privoxy/config

#      HTTP parent looks like this:
#
       forward-socks4   /               127.0.0.1:1080  .
#
#      To chain Privoxy and Tor, both running on the same system, you
#      would use something like:
#
       forward-socks5   /               127.0.0.1:1080 .
 

主要是forward-socks 這兩行，1080是socks代理開啟的埠，根據自己實際情況修改

配置完成後，重啟privoxy，sudo service privoxy restart

新增代理開關函式

vi ~/.bashrc，新增如下程式碼：

function proxy_off(){
    unset http_proxy
    unset https_proxy
    unset ftp_proxy
    unset rsync_proxy
    echo -e "已關閉代理"
}

function proxy_on() {
    export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
    export http_proxy="http://127.0.0.1:8118"
    export https_proxy=$http_proxy
    export ftp_proxy=$http_proxy
    export rsync_proxy=$http_proxy
    export HTTP_PROXY=$http_proxy
    export HTTPS_PROXY=$http_proxy
    export FTP_PROXY=$http_proxy
    export RSYNC_PROXY=$http_proxy
    echo -e "已開啟代理"
}
 

使用的時候，需要開啟http代理時，就在命令列輸入：proxy_on

此種情況多數用於命令列需要連結的伺服器，被牆需要扶梯子時，比如下載android原始碼，chromium原始碼 …
