Python wsgi:ssl-错误无法连接到 HTTPS URL 因为 SSL 模块不可用

Question

我刚刚从 Amazon ec2 实例迁移到 DigitalOcean Droplet。在我运行配置我的 python 应用程序、WSGI 和 apache2 时遇到 SSL 问题之前，一切似乎都工作正常。

水滴：Ubuntu 16.04 Python版本：2.7.12

我的应用程序使用 python requests 模块发出 GET 请求。请求 return 500 并且当我检查我的日志时，我可以看到

我搜索了很多。我试过安装 openssl，其他 conf，但真的很沮丧。我不知道它在 Amazon ec2 中如何流畅运行，但在 Droplet 中却不流畅。

如能提供正确方向的帮助，我们将不胜感激。谢谢

Answer 1

我认为我安装的 python 版本有问题。安装了多个 python 版本，或者构建未正确构建。我在没有安装 python 的 Ubuntu 16.04 digitalOcean machine 上。所以我不得不手动安装它。我遵循了 https://askubuntu.com/questions/101591/how-do-i-install-python-2-7-2-on-ubuntu

上给出的答案

但是，似乎没有任何效果。

最后，我创建了一台全新的机器，但这次是 Ubuntu 14.04，它已经安装了 python。当我安装依赖项并部署我的 Flask 应用程序时，它工作正常。

已将 Ubuntu 16.04（没有 python）更改为 Ubuntu 14.04（安装了 python）。

Answer 2

如果您从源安装 Python，则必须重新运行

./configure
make
sudo checkinstall

安装 openssl 之后（我假设通过 sudo apt install openssl）。

Answer 3

安装openssl和openssl-devel后，不需要再配置python

运行以下命令：

make 
make install

Answer 4

我玩得很开心（Ubuntu 14.04，Python 3.7），但最终还是成功了：

apt install libssl libssl-dev
# compile Python from source:
wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz
tar -xf Python-3.7.5.tgz
./configure --with-openssl=/openssl/  # make sure that this is where x509_vfy.h sits
make && make altinstall
