上一篇介绍了如何将一台旧手机打造成一台云服务器，让任何人都能访问你手机上部署的网站。
但是在实际上当我去找一个开源项目来部署的时候，还是遇到不少坑的，花了挺长时间，才好不容易跑成功。所以这一篇单独来介绍在手机上部署一个现成的开源博客站项目，主要是帮大家避坑，可以顺利部署一个博客站。
我们来部署下这个开源博客系统，python django框架
下载地址：https://gitee.com/lylinux/DjangoBlog.git
第一大坑
Python版本，永远的痛！！！
因为我安装的是最新版的termux，所以默认安装python的时候没有选择版本，所以用的是 python 3.10.6 这个版本，按照项目部署教程来，环境安装这一步就卡住了。。。。
安装项目环境
主要遇到的有两类问题：
- 缺少系统库文件
- 缺少python依赖库
系统库文件指的是linux系统上的底层库，比如binutils、openssl、openssh等;
python依赖库指的是python程序运行时依赖库文件，比如flask、django等;
但是即便是该安装的安装了，最后还是失败，卡在了一个gevents的编译问题，始终绕不过，查阅了网上能尝试的手法，最终有人说将python的版本进行降级，降到3.8版本。
于是开始尝试卸载当前版本，去安装3.8版本，安装好后去编译又遇到其他问题，没有找到解决方案。
于是死马当活马医（快要放弃了），又尝试了3.9版本，也提示了一大堆报错信息，挨个去解决，最终发现3.9的版本可以将这个博客站项目编译通过，并正确运行起来，中间的坑太多，也趟了过来！
第二大坑
手机上python3.9版本哪里去找
下面这个地址给大家提供了各个系统版本的python，可以直接用，很爽！

termux-pod
我这里选择是aarch64版本下的python环境：
因为提供的是deb安装包，可以用下面的命令来安装
dpkg -i python_3.9.7_aarch64.deb
安装成功后，就可以看到python环境已经是3.9的了，可以继续往下。
第三大坑
该装的环境一个都少不了！！！
使用python 3.9来编译还是绕不开安装系统库和python依赖库的问题，总结了以下遇到的错误以及解决方案：
错误 1: 安装python依赖库失败
Could not fetch URL https://pypi.org/simple/flask/:
There was a problem confirming the SSL certificate: HTTPSConnectionPool(
host='pypi.org', port=443): Max retries exceeded with
url: /simple/flask/
(Caused by SSLError("Can't connect to HTTPS URL because the
SSL module is not available.")) - skipping
解决：切换下载的安装源
# 安装的时候加上 -i参数，参数后加上可信任的源下载地址
pip install xxxxxxx
-i http://pypi.douban.com/simple --trusted-host pypi.douban.com
错误 2: 安装mysql_client库失败

----------------------------------------
解决：先安装其他依赖库
# 先安装这个库
pkg install mariadb
错误 3: 安装pillow库失败，缺少jpeg系统库文件

a required dependency when compiling Pillow from source.

解决：
# 先安装下面d系统库
pkg install openjpeg
pkg install libjpeg-turbo
错误 4: 运行开源博客站的时候，缺少库

ModuleNotFoundError: No module named 'tzdata'
解决：
# 安装python依赖库
pip install tzdata -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
闯关成功
经过上面的步骤，我们的python环境就安装成功了，剩下的步骤只要按照博客站的要求来就能轻松部署成了。
