【群晖】自动获取动态IPV4并解析到阿里云域名
首先需要你的域名是在阿里云进行解析使用的才行
获取阿里云的权限
- 登录控制台,在头像下面进入 “AccessKey管理” 页面
- 为了安全原因,建议在“用户”-“创建用户”中创建一个专用帐号(需要对子帐号设置单独的权限,否则无法正常操作API)
- 创建成功后会出现下面的页面,页面中右侧会显示 AccessKey ID 和 AccessKey Secret ,找地方保存值,后面会用到
- 返回用户管理页面,选择刚才创建的用户,选择添加权限
- 点击“域名”相关的权限添加到右侧中
- 点击“解析”相关的权限并添加
- 保存并退出权限页面
编写脚本
注意修改 if name == 'main' 方法中的各个参数值
根据实际需求修改
def __execute()
方法中的各项属性值
修改
__execute
方法中的your.domain
为你自己的站点域名
#!/usr/bin/env python

运行
这里以群晖NAS举例
- 登录群晖“控制面板”-“终端机和SNMP”,打开SSH端口
- SSH登录群晖后台,查看python相关依赖(Python3.8下载可以通过套件方式直接下载,无须后台手动下载安装)
- 上传脚本到群晖文件夹中,这里以 “/volume1/schedule/ipv4_aliyun.py” 为例
- 登录“控制面板”-“任务计划”,新增任务,选择
自定义脚本
- 创建任务,这里的用户最好选择具有管理员权限的帐号
- 自定义任务执行的周期
- 任务设置,这里的脚本路径必须是完整的路径,可以在“文件”管理中右键上传的脚本文件,查看属性中的路径进行复制
