[英]Internal Server Error with Nginx and uWSGI
我正在嘗試在Linode.com上使用Nginx托管應用程序,但在uWSGI配置上卻停留得很早。
我已經使用了“入門”指南和“在Ubuntu 12.04上使用uWSGI和nginx的WSGI(精確的穿山甲)”指南,並且已經成功部署了Nginx(在瀏覽器中獲得了Nginx歡迎消息)。
盡管以上教程適用於Ubuntu 12.04,但我使用的是14.04。
當我開始使用uWSGI配置和“ Hello World” Python應用程序時,問題就開始了。 在瀏覽器中轉到location /
,返回Failed to load resource: the server responded with a status of 500 (Internal Server Error)
,服務器error.log中未記錄任何內容。 雖然location /static
可以工作,並且可以毫無障礙地提供文件。
我已經嘗試了很多事情,並廣泛地尋求針對Google和Stackoverflow的修復程序,但一無所獲,現在我有點沮喪。
感謝您的任何幫助。
這是我的配置文件(我已經隱藏了我的域和IP):

only error log I've got only one time when trying to fix this

我不知道/etc/nginx/sites-enabled/dev.host.in是什么? 如何或為什么* .in? 我認為你應該嘗試
step 1.
create project.ini file
# django_project.ini file
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /home/username/django_project
# Django's wsgi file
module = blog.wsgi
# the virtualenv (full path)
home = /home/username/Env/project
# process-related settings
master = true
pidfile = /tmp/proj_uwsgi.pid
# maximum number of worker processes
processes = 5
# the socket
socket = :8001
# ... with appropriate permissions - may be needed
# chmod-socket = 664
# clear environment on exit
vacuum = true
# background the process
daemonize = /home/username/django_project/error_uwsgi.log
step 2.
create mysite.conf in nginx, vim /etc/nginx/conf.d/mysite.conf
upstream django {
#server unix:///home/username/django_project/djproj.sock; # for a file socket
server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}
# configuration of the server
server {
# the port your site will be served on
listen 80;
# the domain name it will serve for
server_name localhost mysite.com www.mysite.com; # substitute your machine's IP address or FQDN
charset utf-8;
# max upload size
client_max_body_size 75M; # adjust to taste
# Django media
location /media { alias /home/username/django_project/media; # your Django project's media files - amend as required
}
location /static { alias /home/username/django_project/static; # your Django project's static files - amend as required
}
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass 127.0.0.1:8001;#project;
include /home/username/django_project/uwsgi_params; # the uwsgi_params file you installed
}
}
step 3.
ln -s /etc/nginx/uwsgi_params /home/username/django_project/
step 4.
uwsgi --ini django_project.ini
uwsgi --stop /tmp/proj_uwsgi.pid
uwsgi --reload /tmp/proj_uwsgi.pid
