linux dnspod客户端(适用于openwrt,ddwrt, centos, ubuntu等)

几个月前写过一个dnspod脚本,也是用来自动更新动态IP地址到DNSPOD解析顶级域名。周末闲着无聊,重新写了个脚本,在原来的基础上增加了一些功能,比如批量创建,批量更新,批量删除。脚本兼容支持centos, ubuntu这些使用bash的版本,也支持集成busybox的轻量发行版,如openwrt, ddwrt, tomato.但本人只在openwrt, centos和ubuntu上测试过。下面说下使用方法,首先你得有一个顶级域名并已转到dnspod解析,这步就省略了。

下载脚本

下载lino-dnspod或复制脚本内容到任意目录,保存为lino-dnspod, 推荐放在/usr/bin/下面,这样,直接输入文件名即可运行。复制粘贴时要注意dnspod的线路值“默认”,如果你的putty没有选择UTF-8,会导致粘贴后“默认”两字乱码。

配置帐号

打开脚本,填上你自己的dnspod帐号和密码以及要创建和更新的子域名,其它选项可可使用默认的。子域名用单个空格分开即可

email='[email protected]'
password='password'
sub_domains='www ftp test'

创建域名和记录值

lino-dnspod -C zhetenger.com
把zhetenger.com换成你自己的域名,记住是不带www的主域名。如果已经创建过了就可以跳过这步
然后执行创建记录的命令
lino-dnspod -c zhetenger.com &
成功创建域名记录后,脚本会在后台运行,每五分钟检测一次IP是否变化,有变化就更新,这样可减少对dnspod服务的请求次数。

启用随机运行

openwrt的用户可以把下面的脚本拷贝到/etc/init.d/下面,保存为dnspod,然后chmod 755 /etc/init.d/dnspod

#!/bin/sh /etc/rc.common
# Copyright (C) 2006-2011 OpenWrt.org

START=60

start() {
       lino-dnspod -u zhetenger.com &
}

stop() {
        killall lino-dnspod
}

然后,/etc/init.d/lino-dnspod enable
其它版本也可以按照此方法。

命令简介

创建域名命令
lino-dnspod -C example.com
