Raspi config

Start VNC and SSH

Enter the terminal of raspi, sudo raspi-config，and start vnc and ssh with the UI interface.

Alternatively, after you flashed the SD card with raspi os, create a file named ssh (no filename extension, just ssh) at the root of the directory, and SSH will be automatically enabled during the first system startup.

‘Remote host identification changed’ error

When connecting to raspi (or any other ssh hosts) with ssh, if the following error happens:

The solution is to use the following command (replace <IP_ADDRESS> with the IP address of raspi), and connect again

ssh-keygen -R <IP_ADDRESS>

apt-get切换国内源

首先查看linux（树莓派os为debian）版本：lsb_release -a，版本可能是buster或bullseye

然后看一下清华源地址：

https://mirrors.tuna.tsinghua.edu.cn/help/debian/

https://mirrors.tuna.tsinghua.edu.cn/help/raspbian/

似乎只有64位的raspberrypi os才能使用这个源，32位的系统请勿使用，会出错。

内容（可以去访问查看，也可以直接复制下面的文字）：

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free

# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free

把这段文字复制下来，然后更改sources.list文件。这个文件的位置在：/etc/apt/sources.list。可以用sudo vim或者 mousepad 去打开修改。

更改文件完成后，shell执行sudo apt-get update && sudo apt-get upgrade -y，更新这个配置文件并更新所有的包，等待一会儿就完成了！这样apt-get的速度就会快很多。

Install vim

sudo apt-get install vim 

Install zsh and oh my zsh

For reference: mintimate

1 Install zsh and set it as the default terminal

Install zsh：sudo apt-get install zsh

See the path of zsh： which zsh , which should be /bin/zsh or /usr/bin/zsh

Set it as the default shell：chsh -s /bin/zsh, restart terminal or restart system to take effect

2 Install ‘oh my zsh’

One-click setup script:

zsh -c "$(curl -fsSL 'https://api.host.mintimate.cn/fileHost/public/download/1P0R')"

switch theme：

vim ~/.zshrc
# mintimate's theme: steeef
source ~/.zshrc

vim code highlighting, line number display…

vim ~/.vimrc  # don't worry if the file does not exist, vim will create one 

# Add the following————————————————
syntax on " syntax highlighting

set tabstop=4  " 
set softtabstop=4
set shiftwidth=4  "  

set nu   " show line number
colorscheme pablo   " set theme
set ruler   " Show the pointer positon at bottom-right corner when editing


# Save and exit, and it will take effect the next time you enter vim

See CPU usage：

sudo pip install s-tui

sudo s-tui

禁止息屏(?)：

sudo vim /etc/lightdm/lightdm.conf

# 找到[SeatDefaults]下：
#server-command=X 将这一行修改为：
xserver-command=X -s 0 -dpms

# -s 设置屏幕保护不启用
