uwsgi python3插件不起作用

Question

我用 make 编译了 uwsgi 并成功完成，现在我决定用 python3.3 运行我的 django1.5 站点。我检查了文档 (http://projects.unbit.it/uwsgi/wiki/Guide4Packagers) 并通过 apt-get 设置了 python3.3 开发头文件，然后通过以下方式编译插件：

python3.3 uwsgiconfig.py --plugin plugins/python 包 python33

然后它说：

using profile: buildconf/package.ini
detected include path: ['/usr/lib/gcc/i686-linux-gnu/4.7/include', '/usr/local/include','/usr/lib/gcc/i686-linux-gnu/4.7/include-fixed', '/usr/include/i386-linux-gnu', '/usr/include']
*** uWSGI building and linking plugin plugins/python ***
[i686-linux-gnu-gcc -pthread] /usr/lib/uwsgi/python33_plugin.so
*** python33 plugin built and available in /usr/lib/uwsgi/python33_plugin.so ***

似乎一切都做得很好，我确实在该目录中找到了 python33_plugin.so。 nginx正在运行并且没问题，现在我的uwsgi ini文件是这样的：

[uwsgi]  
socket=0.0.0.0:8000 
listen=20
master=true
pidfile=/usr/local/nginx/uwsgi.pid
processes=2
plugins=python33
module=django_wsgi
pythonpath=
profiler=true
memory-report=true
enable-threads=true
logdate=true
limit-as=6048

当我运行“sudo ./uwsgi uwsgi.ini”时，

[uWSGI] getting INI configuration from uwsgi.ini
open("./python33_plugin.so"): No such file or directory [core/utils.c line 3347]
!!! UNABLE to load uWSGI plugin: ./python33_plugin.so: cannot open shared object file: No such file or directory !!!

它没有找到 .so 文件。无论如何，我将 .so 文件复制到 uwsgi 目录，然后再次运行，

我使用的是 ubuntu 13.04，并且预装了 python2.7 和 python3.3。

我设置了 PYTHON33 插件，但 UWSGI 仍然启动 PYTHON2.7，为什么？

有人遇到过这个问题吗？顺便说一句，我不喜欢通过 apt-get 设置 uwsgi 和插件，因为它在任何 PaaS 上都不起作用。

谢谢！

Answer 1

您已经构建了一个嵌入了 python 2.7 的单片 uWSGI 二进制文件，因此插件无法覆盖该内存区域。您可以使用以下方法构建一个简单的单体 python3 二进制文件：

python3 uwsgiconfig.py --build

或者在 python3 中使用 pip

否则，您可以构建一个完全模块化的系统：

python uwsgiconfig.py --build core
python uwsgiconfig.py --plugin plugins/python core python27
python3 uwsgiconfig.py --plugin plugins/python core python33
