Raspberry Pi Raspbian Software source change watchdog enabled

1. Replace Script

The following script please copy directly to the terminal execution!!

For Raspbian-stretch (based on Debian9)

sudo -secho"deb Http://mirrors.ustc.edu.cn/raspbian/raspbian/stretch main Contrib Non-free RPI \ deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/stretch main contrib non-free RPI  " >/etc/apt/sources.listecho"Deb http://mirrors.ustc.edu.cn/ Archive.raspberrypi.org/stretch Main UI" >/etc/apt/sources.list.d/raspi.listexit sudo sudo apt-y upgrade

For Raspbian-jessie (based on DEBIAN8)

 sudo -s  echo -e  " deb Http://mirrors.ustc.edu.cn/raspbian/raspbian/jessie main Non-free contrib \ n DEB-SRC Http://mirrors.ustc.edu.cn/raspbian/raspbian/jessie main Non-free contrib   " >/etc/apt/sources.list  echo -E  deb/HTTP/ Mirrors.ustc.edu.cn/archive.raspberrypi.org/jessie main   >/etc/ Apt/sources.list.d/raspi.listexit  sudo  apt-get update && sudo  apt-get-y upgrade 

2. Other sources: (not tested!) )

Other parts:

1. Chinese language support and Chinese input method

sudo Install -y ttf-wqy-zenheisudoinstall -y Scim-pinyin

2. Install Vim

sudo Install -y vim

If the following error occurs:

The following packages has unmet Dependencies:vim:Depends:vim 2:7.4. 488-72:8.0. 0197-4  is to being installed e:unable to correct problems and you have held broken packages.

First uninstall the Vim-common and then install VIM

sudo apt-get remove vim-commonsudoinstall -y vim

3. Watchdog (prevents the monitoring of Raspberry Pi crash)

When using raspberry to do some applications that require long-term standby, such as downloads, cloud storage, home theater and other applications, one of the problems we often encounter is that the Raspberry Pi will crash due to overheating, we need to restart the Raspberry Pi, and then open the Raspberry Pi application again. This will bring a lot of trouble to our daily operations. Watchdog (watchdog) can make Raspberry Pi never crash.

4.Screen (Let Raspberry Pi never lose the Union)

Using SSH (serare shell, Secure Shell protocol) to remotely control the Raspberry Pi should be our most commonly used way to operate the Raspberry Pi, but when we connect with SSH, we often encounter the problem of sudden disconnection of the connection. Once the connection is disconnected, the operation of the original meter is interrupted, and if used again, it has to be re-started. I'm sure you're upset that you interrupted the Raspberry Pi task because of your computer's standby. Screen to make the Raspberry Pi never lose its way. This method, even if the connection is broken, when we reconnect and still do the original operation, and do not need to start again.

// Install screen directly sudo Install -yscreen//  open a background view (the terminal in the background is not terminated due to disconnection)screen-S terminal name //  and then you can go on with your operation.
