I. Introduction Raspberry Pi

Raspberry Pi Raspberry Pi Foundation is to learn computer programming education designed a miniature computer, can carry a variety of Linux operating system and Windows IoT. As ARM-based Raspberry Pi micro-computer motherboards, with a complete peripheral interfaces, in addition, there is a wealth of programmable GPIO pins, powerful, easy to play, easy to operate.

Second, the installation Raspbian

Search Raspbian enter the official website Download page:

Download Raspbian Buster with desktop and unpack IMG file system image:

Open Win32DiskImager select IMG file and select SD card device, click the Write:

Written after the completion of SD card into the Raspberry Pi, the display is connected, wait for the system to start.

Third, the system configuration chapter

After the system is turned into the desktop, completing some preferences, the following settings before you are prompted to restart:

Enable SSH and VNC (remote desktop):

You can restart the raspberry pie.

If there is no display provides operation, the Raspberry Pi is connected to the router with a network cable, open the Windows command prompt or use Xshell such as SSH client, enter ssh pi @ Raspberry Pi IP (landing router can see):

ssh pi@192.168.43.132

You can also enable VNC using the following method:

Input sudo raspi-config

Keyboard keys to move the highlight up and down the transport Interfacing Options:

Select P3 VNC Enable Enable function VNC

Restart raspberry pie.

VNC Viewer is installed on the computer, in the text box enter the Raspberry Pi IP:

Enter your user name and password Enter:

Successful connection:

FTP file transfer

Open Filezilla New Connection, select SFTP protocol, enter a user name and password:

Successful connection:

Fourth, the software installation chapter

1. apt source configuration

Replace the apt and apt-get's source repository

sudo nano /etc/apt/sources.list

Delete the existing content, then copy and paste:

deb http://mirrors.aliyun.com/raspbian/raspbian/ stretch main non-free contrib 
deb-src http://mirrors.aliyun.com/raspbian/raspbian/ stretch main non-free contrib

Keyboard Ctrl + X, Y, Enter

Replace the Raspberry Pi Foundation maintenance software source:

sudo nano /etc/apt/sources.list.d/raspi.list

All trekking commented first #, then copy and paste

deb http://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ stretch main ui

deb-src http://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ stretch main ui

Ctrl + X，Y，Enter

2. the Java environment

Installation is simple: sudo apt install openjdk-8-jdk

OCD installation: enter oracle official website to download (seemingly still registered)

Network disk share the link: https: //pan.baidu.com/s/1Rzg0xOMXVpZbcq889jMyTQ
extraction code: 1jd0

Select the appropriate version:

Use Filezilla to download the file onto the specified directory:

#-Extracting file
 tar .-Zxf the JDK-8u221-Linux-ARM32-VFP-hflt tar .gz 
# Move the file to opt directory (personal habits) 
sudo  mv . Jdk1 8 .0_221 / / opt / 
# environment variable configuration: 
sudo Nano / etc / Profile 
# add at the end of the document the following information 
JAVA_HOME = / opt / jdk1. 8 .0_221 
Export the PATH = $ JAVA_HOME / bin: $ the PATH 
Export the CLASSPATH =:. $ JAVA_HOME / lib / dt.jar: $ JAVA_HOME / lib / Tools .jar

Ctrl + X，Y，Enter

source / etc / profile and then enter the following information java -version see installation was successful:

3. Tomcat

Simple installation: sudo apt install tomcat8 -y

Open the way: tomcat start

OCD installation: Tomcat into the latest version of the official website to download

# Same with FTP spread raspberry pie, unpack:
 tar zxf the Apache-tomcat- 9.0 . 22 . Tar .gz 
# opt to move to the directory: 
sudo  mv the Apache-tomcat- 9.0 . 22 / opt / 
# change permissions so that access without limitation: 
the sudo  the chmod -R & lt 777 / opt / Apache-tomcat- 9.0 . 22 is / 
# open Tomcat service: 
the bash / opt / Apache-tomcat- 9.0 . 22 is . / bin / Startup SH

In the browser, type http: // Raspberry Pi IP: 8080 can see the Tomcat service is turned on.

4. MySQL

4.1 Installing MySQL:

Installation is simple: sudo apt install mysql-server -y

It may not succeed, depending on the error in the following figure:

Ultimate installation: Go to the debian package mysql mysql site and the entire package on which it depends to download and install one by one: https://packages.debian.org/sid/mysql-server-5.7 ,

Download total of nine packages:

I can download pack good:

Link: https: //pan.baidu.com/s/1ZMBWovALd-SZZMvfmCjyRw
