[英]Flask with UWSGI: Python application not found
我遵循Linode指南来设置Flask应用程序中的UWSGI,并且在我收到“未找到uWSGI错误Python应用程序”之前,尝试将我的应用程序而不是示例应用程序放到一切正常。
我在/srv/www/xxx.com/xxx/
中的文件结构为:
app/
__init__.py
uwsgi.py
__init__.py
文件包含用于运行应用程序的行:
if __name__ == '__main__':
app.run()
然后uwsgi.py
导入应用程序:
#!flask/bin/python
from app import app
if __name__ == "__main__":
app.run(debug = False)
当我手动尝试运行python uwsgi.py
该应用似乎可以正常运行,因此没有错误或错误的导入。 如果我将uwsgi.py
的内容更改为以下内容(来自示例):
import os
import sys
sys.path.append('/srv/www/example.com/application')
os.environ['PYTHON_EGG_CACHE'] = '/srv/www/example.com/.python-egg'
def application(environ, start_response):
status = '200 OK'
output = 'Hello World!'
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
该应用程序似乎正在运行,因此UWSGI和nginx可以正常运行并运行uwsgi.py
文件,但是当我将其指向我的应用程序uwsgi.py
无法运行。
我的uwsgi配置:
<uwsgi>
<plugin>python</plugin>
<socket>/run/uwsgi/app/xxx.com/xxx.com.socket</socket>
<pythonpath>/srv/www/xxx.com/application/xxx/</pythonpath>
<app mountpoint="/">
<script>uwsgi</script>
</app>
<master/>
<processes>4</processes>
<harakiri>60</harakiri>
<reload-mercy>8</reload-mercy>
<cpu-affinity>1</cpu-affinity>
<stats>/tmp/stats.socket</stats>
<max-requests>2000</max-requests>
<limit-as>512</limit-as>
<reload-on-as>256</reload-on-as>
<reload-on-rss>192</reload-on-rss>
<no-orphans/>
<vacuum/>
</uwsgi>
我的nginx配置:
server {
listen 80;
server_name $hostname;
access_log /srv/www/xxx.com/logs/access.log;
error_log /srv/www/xxx.com/logs/error.log;
location / {
uwsgi_pass unix:///run/uwsgi/app/xxx.com/xxx.com.socket;
include uwsgi_params;
uwsgi_param UWSGI_SCHEME $scheme;
uwsgi_param SERVER_SOFTWARE nginx/$nginx_version;
}
location /static {
root /srv/www/xxx.com/public_html/static/;
index index.html index.htm;
}
}
这是uwsgi错误日志:
added /srv/www/xxx.com/application/xxx/ to pythonpath.
- unable to load app 0 (mountpoint='/') (callable not found or import error)
- *** no app loaded. going in full dynamic mode ***

任何人都可以指出我在哪里犯错? 我花了数小时尝试各种解决方案,但似乎没有任何效果,我必须省略了一些重要的内容,但找不到它。
尝试添加<callable>application</callable>
