Raspberry Pi 2 / 3 Ubuntu MATE


Raspberry Pi 2 / 3 Ubuntu MATE


Ubuntu MATE
https://ubuntu-mate.org/raspberry-pi/


1. 下載Ubuntu MATE 16.04.1 LTS
https://ubuntu-mate.org/download/


2.使用7-Zip or Winrar 解壓縮.xz檔案, 得到.img

Windows OS使用Win32 Disk Imager 將.img檔案燒錄至Micro SD

3.將Micro SD裝入Raspberry Pi 2 / 3 並安裝Ubuntu MATE16.04.1


4.Re-size file system

sudo fdisk /dev/mmcblk0

d,2  n,p,2,[enter],[enter]  w

after reboot:

sudo resize2fs /dev/mmcblk0p2

5. 設定Wi-Fi or Ethernet


6. HDMI disable overscan

sudo nano /boot/config.txt

#disable_overscan=1

delete the #

7. Install SSH

http://morred.blogspot.tw/2015/05/raspberrypi2-ssh.html

8. Update system

sudo apt-get update
sudo apt-get upgrade

RaspberryPi/Pi2 SSH 連線設定

RaspberryPi/Pi2 SSH 連線設定


Install an SSH server for remote access:

$ sudo apt-get install openssh-server

修改相關設定

SSH預設port為22,使用預設值容易受攻擊,建議修改

sudo nano /etc/ssh/sshd_config

@# What ports, IPs and protocols we listen for (約第4、5行)
Port 22

將紅字部分修改為自己設定的port

存檔後,重新啟動Pi後完成修改



使用PuTTY連線

相關設定如上

Host Name(192.168.1.123)修改為RaspberryPi的IP

Port(1234)則使用剛剛自己設定的port
