uWSGI和Python> 3.4

Question

我有一个django项目，当前正在使用以下配置运行：

• Debian 8
• Python 3.4
• 皇帝模式下的uWSGI

我从源代码安装了Python 3.6.1，并使用python 3.6创建了一个新的虚拟环境（我使用virtualenvwrapper），但是让该项目以uwsgi启动似乎有些麻烦。

配置文件如下：

[uwsgi]
plugins = python3
project = %n
module = myapp.wsgi:application
home = path_to_new_env
socket = /var/run/uwsgi-%n.sock
chdir = path_to_new_env/myapp/myapp
processes = 4
max-requests = 5000
chmod-socket = 666
chown-socket = user:user
master = True
vacuum = True
logto = /var/log/%n_LOG.log
buffer-size = 32768

我的印象是该python3插件将包括对python 3.6的支持，但日志表明仍在使用Python 3.4.x解释器。

在已安装的uwsgi插件列表中，我看到了对python 2、3和3.4的支持，但仅此而已。我不确定启动时设置正确的解释器需要做什么。

任何意见，将不胜感激。

更新：我已经尝试为python 3.6构建一个uwsgi插件：

Answer 1

我最近想出了一个解决方案，python3.6应用与uwsgi服务器。

wget https://projects.unbit.it/downloads/uwsgi-latest.tar.gz
tar -xvzf uwsgi-latest.tar.gz

mv uwsgi-2.0.17 uwsgi
cd uwsgi
make PROFILE=nolang # no language defaults allows flexibility for python versions

PYTHON=python3.6 # or --> PYTHON=/usr/bin/python3.6

./uwsgi --build-plugin "plugins/python python36"
mv python36_plugin.so plugins/python
cd ..
sudo mv uwsgi /usr/local
sudo ln -s /usr/local/uwsgi/uwsgi /usr/local/bin/uwsgi

然后，您可以在配置文件中使用它，如下所示：

[uwsgi]

plugins-dir = /usr/local/uwsgi/plugins/python
plugin = python36

为您希望在 uwsgi 服务器上提供的任何其他 Python 版本模仿此过程。

解决方案：

1）下载uwsgi源tarball

2) 按照此处的构建说明进行操作

请注意，对于 python3.6，您需要使用该标志配置 python--enable-shared并在构建 uWsgi 插件之前声明一个额外的环境变量：export CFLAGS="$CFLAGS -fPIC"

3) 使用支持的插件安装新的 uwsgi 二进制文件：cp uwsgi /usr/local/bin/
