安装vim

sudo apt vim

在镜像中添加一个root用户

先添加一个普通用户

adduser wmj

然后将这个用户赋予root权限：修改/etc/sudoers文件，找到下面一行，在root下面添加一行“wmj ALL=(ALL) ALL”

以下操作均在wmj用户下执行

安装搜狗拼音

点击左上角按钮，将deb复制到当前目录，然后安装，下文同理

sudo dpkg -i [tab补全]

sudo apt -f install

sudo dpkg -i [tab补全]

安装vscode

sudo dpkg -i [tab补全]

安装zsh等

sudo apt install git curl wget zsh python3-pip autojump net-tools openssh-server cmake gcc python-pip python-wstools

# pip
cp pip/pip.conf /home/wmj/.pip

# fonts
cp -r fonts/ /home/wmj/.fonts

# zsh
cp zsh/zshrc /home/wmj/.zshrc

sudo cp zsh/zshrc_root /root/.zshrc

# oh-my-zsh
【gitee下载oh-my-zsh源码中的tools/install.sh，等修改好install中的REPO和REMOTE的地址（改为gitee仓库的地址），执行完install.sh后再执行以下两条】
cp -r zsh/oh-my-zsh /home/wmj/.oh-my-zsh
sudo cp -r zsh/oh-my-zsh /root/.oh-my-zsh

# 设置zsh为默认shell
chsh -s /usr/bin/zsh
sudo chsh -s /usr/bin/zsh

charactor not in range解决方法

.bashrc 文件底部添加以下两行：
export LC_ALL=C.UTF-8
export LANG=C.UTF-8

编译安装opencv3.4.10

安装相机驱动

run完把inc里面的头文件复制到/usr/include

自定义系统设置
跳过

备注

1. 进入镜像安装的时候会强制让新建一个用户，要新建一个名称不为事先写入镜像的用户，进入系统后这个新建的用户自然会消失，但是设备名会与新建用户时设定的用户名一致
2. 做镜像的时候，封装镜像前记得输入sudo passwd把密码再设置一次，否则进入系统后要重新设置密码
3. 事先更换的软件源又被换回去了，必须手动再换一次
4. 搜狗输入法要重新安装
5. ssh密钥要生成
