First, you have to have a vro. Otherwise, the following content cannot be implemented.Second, you have to apply for a free dynamic domain name resolution, because I use TP-LINK router, only support peanut shells, so I applied for dynamic domain name resolution of peanut shells.It's easy to apply for a peanut shell, open the http://www.oray.com, click "register" on the top and apply for a peanut shell passport.
After the application is completed, click my console-product management-Domain Name M
The Raspberry Pi CPU is protected by a hardware watchdog, which can be implemented by installing modules and guarding the watchdog program to prevent Raspberry Pi from freezing.Installation method One:Source code for WATCHDOG.SH:
