0x00 代码

废话不多说, 上代码, 度娘也有很多的

0x01 Python 环境

阿里出品可以用 Python 2 也可以用 Python 3, 自行选择, 安装 pip 工具, 不同平台自行度娘

• Python 2.x 没有权限的加入 sudo

pip install aliyun-python-sdk-core
pip install aliyun-python-sdk-mts
pip install aliyun-python-sdk-alidns

• Python 3.x 没有权限的加入 sudo

pip install aliyun-python-sdk-core-v3
pip install aliyun-python-sdk-mts
pip install aliyun-python-sdk-alidns

0x02 我的过程

1. ssh 进入 NAS

# ~ [14:02:12]
$ ssh zwyxxd@121.204.5.22
zwyxxd@121.204.5.22's password:
zwyxxd@zwyxxd:~$ ls
domain_setting  Drive  scripts
zwyxxd@zwyxxd:~$

2. 我的脚本在 scripts 内

3. 切换 root 权限输入 sudo -i 在输入密码回车

4. 执行 0x01 Python 环境 的命令
   

   aliyun-python-sdk-core
   aliyun-python-sdk-mts
   aliyun-python-sdk-alidns

5. 环境配置完成后直接执行 python /path/aliyunddns.py

6. 如果有报错是请求相关的, 请查看阿里云错误代码

7. 以上均成功后就可以添加入 NAS 的计划任务中

# 此处换行执行两个命令
cd /volume1/homes/zwyxxd/scripts/aliyunddns 
python aliyunddns.py
