1、添加新用户
由于 termux/ubuntu 默认创建和登录的是 root 用户，root 用户的 home 目录在 /root 下，这个使用起来很不方便，使用 root 用户也不太习惯，有必要创建新用户
# 创建新用户
useradd -d /home/new_user_name -m new_user_nem # 新用户 home 目录是 /home/new_user_name，新用户用户名是 -m 后的 new_user_name
# 切户到新建的用户
su new_user_name
cd # 进入 new_user_name 的 home 目录
# 设置新用户密码
passwd new_user_name
whoami # 查看当前用户
2、安装图形桌面
桌面环境没什么额外的用途，只是徒增资源消耗，就不装了。大部分的开发需求都可以通过在电脑安装的 vscode 使用 ssh 远程连接满足
3、环境配置
切换 shell 为 bash
termux 默认使用 sh shell，使用起来会很不习惯，可以切换为习惯的 shell
# 查看当前 shell echo $SHELL # 通用 echo $0 # 部分 shell 不支持 # 查看系统中安装了哪些shell cat /etc/shells # termux ubuntu 一般默认有 /bin/sh /bin/bash /bin/rbash /bin/dash 等 shell # 通过修改 /etc/passwd文件来修改用户的默认 shell vim /etc/passwd # 把文件中对应用户的那一行最后的 shell 修改为目标 shell # 重新登录用户即可更换镜像源（在 termux ubuntu 中不需要在更换源，更换后可能会导致装软件的时候无法定位到对应的包）
# 备份镜像源列表 cp /etc/apt/sources.list /etc/apt/sources.list.bk # 编辑镜像源列表文件，这里替换的是中科大的镜像源 # 中科大源 deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse # 国内的其他源 # 阿里源 deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse # 清华源 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse #deb cdrom:[Ubuntu 20.04.3 LTS _Focal Fossa_ - Release amd64 (20210819)]/ focal main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://cn.archive.ubuntu.com/ubuntu/ focal main restricted # deb-src http://cn.archive.ubuntu.com/ubuntu/ focal main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://cn.archive.ubuntu.com/ubuntu/ focal-updates main restricted # deb-src http://cn.archive.ubuntu.com/ubuntu/ focal-updates main restricted ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

当使用新添加的用户使用 apt 安装软件的时候，可能会出现报错
这个可能和 termux 对多用户支持不好有关，因此还是不要使用新用户了，避免掉进其他的坑，直接使用 root 吧
使用 root 安装软件则没有这个问题
更新 pip 源
# 注意使用 root 用户 cd mkdir .pip vim ~/.pip/pip.conf # 文件中添加内容 [global] index-url = http://pypi.douban.com/simple [install] trusted-host=pypi.douban.com常用工具安装
sudo apt install net-toolssudo apt install gccsudo apt install g++sudo apt install cmakeapt install pipx
安装这个包的原因主要是在使用 pip 安装 python 包的时候，可能会有报错
安装完 pipx 之后，将其添加到 PATH
pipx ensurepath接下来就可以使用
pipx install package_nme来安装 python 包另外，也可以强行安装
pip install --upgrade --force-reinstall package_name --break-system-packages
