我正在尝试通过 Nginx 和 uWSGI 部署一个 Django 项目。如果我手动运行该项目，python manage.py runserver :8000它可以正常工作，所以我猜问题不在于项目本身。
我在专用的虚拟环境中安装了 Django 和依赖项，并将项目放入其中。我还在虚拟环境之外安装了 nginx 和 uwsgi，并开始创建配置文件：
/etc/nginx/sites-available/myproject（在启用站点的符号链接）：
upstream uwsgi_myproject {
server 127.0.0.1:5678;
}
server {
listen 80;
server_name my.url.net;
set $home /path/to/myvirtualenv;
access_log /path/to/myvirtualenv/log/access_uwsgi.log;
error_log /path/to/myvirtualenv/log/error_uwsgi.log;
client_max_body_size 10m;
keepalive_timeout 120;
location / {
uwsgi_pass uwsgi_myproject;
include uwsgi_params;
gzip on;
uwsgi_param UWSGI_CHDIR $home/path/to/myproject;
uwsgi_param UWSGI_SCRIPT uwsgi;
uwsgi_param UWSGI_PYHOME $home;
root $home;
}
location /static/ {
alias /path/to/myvirtualenv/path/to/myproject/static/;
expires max;
autoindex off;
}
location /media_adm/ {
alias /path/to/myvirtualenv/lib/python2.7/site-packages/grappelli/static/;
autoindex off;
}
}
/etc/init/uwsgi_myproject.conf：
description "uWSGI starter for myproject"
start on (local-filesystems and runlevel [2345])
stop on runlevel [016]
respawn
exec /path/to/myvirtualenv/bin/uwsgi \
--uid venvowner \
--home /path/to/myvirtualenv \
--pythonpath /path/to/myvirtualenv/path/to/myproject/ \
--socket 127.0.0.1:5678 \
--chmod-socket \
--module wsgi \
-b 8192 \
--logdate \
--optimize 2 \
--processes 2 \
--master \
--logto /path/to/myvirtualenv/log/uwsgi.log
/path/to/myvirtualenv/path/to/myproject/wsgi.py：
import os, sys, site
site.addsitedir('/path/to/myvirtualenv/lib/python2.7/site-packages')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
然后我重启机器并尝试连接到 my.url.net，但是没有响应（当我在导入 myproject 之前安装了 nginx 时，它响应“欢迎使用 Nginx！”）。我注意到lsof | grep LISTEN上游套接字尚未创建。日志没有输出任何相关信息，因此我尝试使用相同的参数手动执行 uwsgiuwsgi_myproject.conf并得到以下输出：
current working directory: /etc/init
detected binary path: /path/to/myvirtualenv/bin/uwsgi
uWSGI running as root, you can use --uid/--gid/--chroot options
*** WARNING: you are running uWSGI without its master process manager ***
your processes number limit is 6674
your memory page size is 4096 bytes
detected max file descriptor number: 1024
lock engine: pthread robust mutexes
thunder lock: disabled (you can enable it with --thunder-lock)
The -s/--socket option is missing and stdin is not a socket.
编辑：所以我尝试的最后一件事是重新排序参数。现在 --socket 参数已成功处理，但我仍然在输出行中收到此消息：
*** no app loaded. going in full dynamic mode ***
我一直在阅读的一些文件：
关于我遗漏或忽略了什么，您有什么想法吗？
继续：我再次查看了文档并尝试了不同的方法：使用 .ini 文件并手动运行它以查看会发生什么：
虽然有点丑陋，但是可以这么说：
[uwsgi]
socket = 127.0.0.1:5678
uid = venvowner
chdir = /path/to/myvirtualenv
home = /path/to/myvirtualenv
virtualenv = /path/to/myvirtualenv
pythonpath = /path/to/myvirtualenv/path/to/myproject
module = wsgi
master = true
optimize = 2
processes = 2
logto = /path/to/myvirtualenv/log/uwsgi.log
我获得了一些有用的日志：
*** Python threads support is disabled. You can enable it with --enable-threads ***
*** Operational MODE: preforking ***
ImportError: No module named wsgi
unable to load app 0 (mountpoint='') (callable not found or import error)
*** no app loaded. going in full dynamic mode ***
*** uWSGI is running in multiple interpreter mode ***
工人已经生成，但堆栈显然失败了。我会改天再来处理这个问题。
答案1
最后，我让它工作了。感谢@DhirajThakur 的评论，它帮助我找到正确的方向。
/etc/init/uwsgi_myproject.conf：
description "uWSGI starter for myproject"
start on (local-filesystems and runlevel [2345])
stop on runlevel [016]
respawn
exec /usr/local/bin/uwsgi /etc/init/myproject.ini
/etc/init/myproject.ini：
[uwsgi]
master = true
socket = 127.0.0.1:5678
uid = venvowner
chdir = /path/to/myvirtualenv
home = /path/to/myvirtualenv
virtualenv = /path/to/myvirtualenv
pythonpath = /path/to/myvirtualenv/path/to/myproject
wsgi-file = /path/to/myvirtualenv/path/to/myproject/wsgi.py
optimize = 2
processes = 2
logto = /path/to/myvirtualenv/log/uwsgi.log
不知为何，我感觉我解决问题的方式有点太难了。
