uwsgi service is not starting
提问by tomis
I have a python application (concrete Django) running on my server. Before yesterday, it was successfully running under apache with mod-wsgi with almost no problem. I had two main reason to switch to nginx:
我在我的服务器上运行了一个 python 应用程序（具体的 Django）。昨天之前用mod-wsgi在apache下成功运行，几乎没有问题。我有两个主要原因切换到 nginx：
- performance - under nginx, I have almost half time for each request
- two applications together was not running successfully under apache - solved by nginx
- third reason is better configuration for me
- 性能 - 在 nginx 下，我几乎每个请求都有一半的时间
- 两个应用程序一起在 apache 下没有成功运行 - 由 nginx 解决
- 第三个原因是对我来说更好的配置
I have a problem with the uwsgi service. First, I will include the app's wsgi file:
我的 uwsgi 服务有问题。首先，我将包含应用程序的 wsgi 文件：
import os
import sys
path = os.path.abspath(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
if path not in sys.path:
sys.path.append(path)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "usporion.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
Then I have uwsgi.ini file for init app, located under /etc/uwsgi/apps-enabled/usporion.ini:
然后我有用于 init 应用程序的 uwsgi.ini 文件，位于/etc/uwsgi/apps-enabled/usporion.ini：
[uwsgi]
plugins = python
uid = www-data
gid = www-data
uwsgi-socket = /srv/sockets/usporion.sock
chmod-socket = 664
chdir = /srv/www/usporion
pythonpath = /srv/www/usporion
module = usporion.wsgi
env = DJANGO_SETTINGS_MODULE=usporion.settings
logdate = True
logto = /var/log/uwsgi/usporion.log
#daemonize = /var/log/uwsgi/usporion.log
vacuum = True
max-requests = 1000
processes = 5
threads = 10
workers = 5
vhost = True
Note: I have tried to have daemonize uncommented (but this is not working with current usage).
注意：我曾尝试将 daemonize 取消注释（但这不适用于当前使用情况）。
Lastly, I have this nginx config:
最后，我有这个 nginx 配置：
upstream django {
server 95.168.193.219:80;
}
server {
listen 95.168.193.219:80;
server_name usporion.cz;
return 301 $scheme://www.usporion.cz$request_uri;
}
server {
listen 95.168.193.219:80;
server_name www.usporion.cz;
charset utf-8;
client_max_body_size 100M;
location /media {
alias /srv/www/usporion/media;
expires 1d;
}
location /static {
alias /srv/www/usporion/static;
expires 1d;
}
location / {
root /srv/www/usporion;
include uwsgi_params;
uwsgi_pass unix:///srv/sockets/usporion.sock;
}
}
Running the command uwsgi --ini /etc/uwsgi/apps-enabled/usporion.iniis working fine and I'm able to see app working on the web. However, if I do service uwsgi start, service is not started (FAIL) with no message and I cannot find anything in the logs. Running this service without usporion.iniin apps-enabled is working fine.
运行命令uwsgi --ini /etc/uwsgi/apps-enabled/usporion.ini运行良好，我可以看到应用程序在网络上运行。但是，如果我这样做service uwsgi start，则服务未启动（失败）且没有消息，并且我在日志中找不到任何内容。usporion.ini在不启用应用程序的情况下运行此服务工作正常。
I would be pleased for any help which with I can avoid running uwsgi "service" under screen but run as normal service.
我很乐意提供任何帮助，因为我可以避免在屏幕下运行 uwsgi“服务”但作为正常服务运行。
Here is the dist info:
这是dist信息：
root@[name]:/etc/nginx/sites-enabled# uname -a
Linux [name] 2.6.32-5-amd64 #1 SMP Sun Sep 23 10:07:46 UTC 2012 x86_64 GNU/Linux
root@[name]:/etc/nginx/sites-enabled# cat /etc/debian_version
6.0.7
root@[name]:/etc/nginx/sites-enabled# nginx -v
nginx version: nginx/1.2.6
root@[name]:/etc/nginx/sites-enabled# uwsgi --version
1.2.3-debian
root@[name]:/etc/nginx/sites-enabled# python --version
Python 2.7.3
Lastly, if someone would like to give me some advice to configure (I'm new to nginx and it's welcome), this is 8-core Xeon server 2.4GHz with 16GB of RAM, half of that is reserved for this app.
最后，如果有人想给我一些配置建议（我是 nginx 的新手，欢迎使用），这是 8 核 Xeon 服务器，2.4GHz，16GB RAM，其中一半是为这个应用程序保留的。

Error is uwsgi configuration:
错误是uwsgi配置：
[uwsgi]
plugins = python
uid = www-data
gid = www-data
uwsgi-socket = /srv/sockets/usporion.sock
chmod-socket = 664
chdir = /srv/www/usporion
pythonpath = /srv/www/usporion
wsgi-file = /srv/www/usporion/usporion/wsgi.py
env = DJANGO_SETTINGS_MODULE=usporion.settings
logdate = True
logto = /var/log/uwsgi/usporion.log
#daemonize = /var/log/uwsgi/usporion.log
vacuum = True
max-requests = 1000
master = True
enable-threads = True
processes = 5
threads = 10
vhost = True
Difference is in wsgi-file, what have replaced old moduleconfig value. Then, error about missing wsgi file appeared (first written error). daemonizeis not necessary here as debian's service is automaticly defined this. Still, I think vacuum, logtois not neccessary there, as well chmod-socketand uwsgi-socket- all of them is defined by debian's service. I will aprove this and complete this answer.
不同之处在于wsgi-file，替换了旧的module配置值。然后，出现丢失 wsgi 文件的错误（第一个写入错误）。 daemonize这里没有必要，因为 debian 的服务是自动定义的。尽管如此，我认为vacuum,logto也不是必需的，chmod-socket而且uwsgi-socket- 所有这些都由 debian 的服务定义。我会批准这一点并完成这个答案。
Still, from trying etc., this configuration is basic and everything else should be denifed automaticly or have some default value or by Django itselves:
尽管如此，从尝试等来看，这个配置是基本的，其他一切都应该被自动拒绝或有一些默认值或由 Django 本身：
[uwsgi]
plugins = python
chdir = /srv/www/usporion
pythonpath = /srv/www/usporion
wsgi-file = /srv/www/usporion/usporion/wsgi.py
