uWSGI + nginx爲django項目，錯誤與strting uwsgi

Question

我嘗試啓動web服務器上的nginx + uwsgi，os - debian（3.1.0-1-amd64 x86_64）上的django nginx 1.1.8-1，uwsgi 0.9。 8.3-1 配置：

<uwsgi> 
<socket>/tmp/uwsgi.sock</socket> 
<process>1</process> 
<master/> 
<enable-threads/> 
<uid>33</uid> 
<gid>33</gid> 
<pidfile>/tmp/uwsgi.pid</pidfile> 
</uwsgi> 

在文件/etc/uwsgi/apps-enabled/webapp.xml nginx的配置

location/{ 
     uwsgi_pass unix:///tmp/uwsgi.sock; 
     include uwsgi_params; 
     uwsgi_param UWSGI_SCRIPT webapp; 
     uwsgi_param UWSGI_CHDIR /data/web/webapp/webapp; 
    } 

所有PROJET在/數據/信息網/ Web應用/ web應用/，這裏setting.py，網址等。 在/data/web/webapp/webapp/webapp.py

import sys, os 
import django.core.handlers.wsgi 
sys.path.insert(0, '/data/web/webapp/webapp') 
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' 
application = django.core.handlers.wsgi.WSGIHandler() 

UID和GID 33是www數據用戶 嘗試運行uwsgi作爲

root#uwsgi -s /var/run/uwsgi.sock -x /etc/uwsgi/apps-enabled/webapp.xml

[uWSGI] parsing config file /etc/uwsgi/apps-enabled/webapp.xml 
*** Starting uWSGI 0.9.8.3-debian (64bit) on [Wed Dec 14 21:42:02 2011] ***

setuid() to 33 
your memory page size is 4096 bytes 
unlink(): Permission denied [socket.c line 38] 
bind(): Address already in use [socket.c line 70] 

如何允許他們希望？這有什麼問題.. 如果我運行uwsgi爲根錯誤消失了，我看

uwsgi socket 0 bound to UNIX address /var/run/uwsgi.sock fd 3

*** uWSGI is running in multiple interpreter mode *** 
spawned uWSGI master process (pid: 20732) 
spawned uWSGI worker 1 (pid: 20733, cores: 1) 

，但是當我試圖訪問服務器，ngix返回502錯誤頁面。多：在nginx的日誌權限錯誤：

2011/12/14 21:57:17 [crit] 20739#0: *1 connect() to unix:///tmp/uwsgi.sock failed (13: Permission denied) while connecting to upstream, client: 10.10.3.111, server: ******, request: "GET /favicon.ico HTTP/1.1", upstream: "uwsgi://unix:///tmp/uwsgi.sock:", host: "****.****.**" 

如果/tmp/uwsgi.sock的所有者更改爲nginix用戶在運行時（www數據），他寫了其他日誌

[error] 20739#0: *21 upstream prematurely closed connection while reading response header from upstream, 

，但仍錯誤502（

如何解決這個問題呢？有些人可以幫助我.. 真的想使用的nginx + uwsgi，而不是Apache的。 感謝

但是，解決方案已接近:) 現在我使用tcp套接字，並更改了uwsgi配置並安裝了更多的套件。 是一個重要的選擇 - 自動加載。 現在uwsgi具有這樣的配置：

<uwsgi> 
<module>webapp</module> 
<socket>127.0.0.1:5080</socket> 
<pythonpath>/data/web/webapp/webapp</pythonpath> 
<autoload/> 
<daemonize>/var/log/uwsgi_webapp.log</daemonize> 
<processes>1</processes> 
<uid>33</uid> 
<gid>33</gid> 
<enable-threads/> 
<master/> 
<harakiri>120</harakiri> 
<max-requests>5000</max-requests> 
</uwsgi> 

還有解決其他問題.. uwsgi不使用主系統Python版本> _ <

他使用Python 2.6.7，但主要的系統版本是2.7.2以及爲此安裝的所有python模塊，所以在日誌中有很多錯誤 - 重複嘗試導入不存在的，許多典型錯誤之一：

File "/usr/lib/python2.6/dist-packages/django/db/__init__.py", line 78, in <module> 
    connection = connections[DEFAULT_DB_ALIAS] 
    File "/usr/lib/python2.6/dist-packages/django/db/utils.py", line 93, in __getitem__ 
    backend = load_backend(db['ENGINE']) 
    File "/usr/lib/python2.6/dist-packages/django/db/utils.py", line 51, in load_backend 
    raise ImproperlyConfigured(error_msg)

Try using django.db.backends.XXX, where XXX is one of: 
    'dummy', 'mysql', 'oracle', 'postgresql', 'postgresql_psycopg2', 'sqlite3' 
Error was: No module named django_mongodb_engine.base 

so ..怎麼設置uwsgi的python版本？

Answer 1

unix套接字必須遵守文件許可方案。所以/ var/run必須可以通過www-data寫入，並且nginx必須能夠讀/寫/ var/run/uwsgi。襪子

如果你不熟悉這樣的事情，你應該使用TCP套接字（選擇一個端口，你準備好）

Answer 2

how set version of python for uwsgi?

設置選項插件在uwsgi設置：

[uwsgi] 
... 
plugins = python27 
...
