Nas is so sweet to a loser programmer like me who can’t afford aliyun server.

conditions

  • Cluster hui or black cluster hui
  • Ali cloud domain name application, need to record
  • There is public IP in the home (not fixed, will often change), telecom generally have, no words can apply to customer service. Other broadband please Baidu
  • The router sets up port forwarding or DMZ hosts

The advantages of this approach are obvious

  • No need to use peanut shell FRP to do Intranet penetration, completely free, only the aliyun domain name fee
  • Speed depends on home broadband. For example, my home gigabit broadband, upload is a hundred megabytes, measured company download files can reach 12 megabytes per second
  • Super stable, no problems generally

The disadvantages are also obvious

  • Have a public IP address
  • Unable to use ports 80 and 443 (blocked), you will definitely need a port number to deploy the site

Copy the code

I have placed this script in the following location, which can be changed according to your needs

Open The CDH Control Panel -> Plan the task

A new task is added. In the screenshot, the task is scheduled to be executed every 10 minutes from 7:00-20:50 every day

The script format is as follows

Sh [sh script address] [AccessKey ID] [AccessKey] Secret [top-level domain] [secondary domain]Copy the code
