I am running apache (mod_uwsgi) with uwsgi. in settings i have unix socket pointing to /var/uwsgi/ . I am also pointing to this socket from apache vhost. If i try to access this vhost, i got error (in apache log):
apache log:
uwsgi: unable to connect to uWSGI server: Permission denied
uwsgi config:
<uwsgi>
<pythonpath>/home/user/django_projects/project/</pythonpath>
<master/>
<no-orphans/>
<processes>1</processes>
<optimize>0</optimize>
<home>/home/user/Envs/project/</home>
<limit-as>128</limit-as>
<chmod-socket>664</chmod-socket>
<gid>www-data</gid>
<pidfile>/var/uwsgi/project.pid</pidfile>
<socket>/var/uwsgi/project.sock</socket>

<daemonize>/var/uwsgi/project.log</daemonize>
<chdir>/home/user/django_projects/project/</chdir>
</uwsgi>
and apache config:
<Location />
Options FollowSymLinks Indexes
SetHandler uwsgi-handler
uWSGISocket /var/uwsgi/project.sock
</Location>
what am i missing? I also tried changing chmod socket to 777..no success..
I run mod_wsgi with django, but consider adding a Directory block to the Apache config.
<Directory /var/uwsgi/>
Options All
</Directory>
And if that works, make the "All" statement more specific to your needs.

I have a production server with apache and django installed using mod_wsgi.
The django application has a REST API that serves some info when a GET request is sent.
This has always worked fine on the develop server, were we ran django using manage.py in a screen. Now we created a production server with apache running django but this API returns Error 500 when running wget from localhost or other machines in the same network (using 192.168.X.X IP).
Here's the output from wget:
~$ wget localhost:80/someinfo
--2020-04-02 16:26:59-- http://localhost/someinfo
Resolving localhost (localhost)... 127.0.0.1
Connecting to localhost (localhost)|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 500 Internal Server Error
2020-04-02 16:26:59 ERROR 500: Internal Server Error.
It seems that the connection succeeds, so I guess it's not an apache problem. The error comes from the API response.
The error in apache error.log looks like this:
127.0.0.1 - - [02/Apr/2020:14:24:36 +0000] "GET /someinfo HTTP/1.1" 500 799 "-" "Wget/1.19.4 (linux-gnu)"
question: what is the number after 500? Sometimes is 799 and other times is 803.
But if the request is done using the public IP of the server from outside (i.e. from the browser) the API works fine and I see the correct information.
I already checked django's allowed hosts and it was accepting localhost, and the 192.168.X.X IP of the other machine. In the end I left django's settings.py like this:
#ALLOWED_HOSTS = ['localhost', '127.0.0.1', '192.168.1.101']
ALLOWED_HOSTS = ['*']
Note: 192.168.1.101 is the machine that tries to make the GET request.
The final goal of all this is to be able to make a GET request from a python script running in that machine (which already works if django runs via manage.py).
My apache.conf:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
#DocumentRoot /var/www/html
Alias /static /home/myuser/myproject/django/static_root
<Directory /home/myuser/myproject/django/static_root>

WSGIProcessGroup myproject
WSGIScriptAlias / /home/myuser/myproject/django/myproject_django/wsgi.py
</VirtualHost>
I tried running django via manage.py and the wget from localhost works just fine. The problem only appears when django is ran by apache.
I also tried the solution given in this post, but changing the line does not fix the error.
I have some doubts concerning this error:
how does apache run django?
does restarting apache2 service also restart django? (thus, reading again the settings.py)
Is there any other django settings file rather than the one I'm editing?
how can I see django logs? I don't have the console now so I can't see real time prints.
I appreciate a lot any help.
I finally managed to solve it myself.
It turns out wsgi handles requests from localhost or external IPs as different instance groups. So all I had to do is put
WSGIApplicationGroup %{GLOBAL}
in /etc/apache2/sites-available/000-default.conf
I am getting a server error with trying to reverse proxy to Gunicorn.
My virtual host file looks like this:
<virtualhost *:80>
<Location /myApp>
ProxyPreserveHost On
ProxyPass "http://127.0.0.1:8090/"
ProxyPassReverse "http://127.0.0.1:8090/"
</Location>
</virtualhost>
And I'm running Gunicorn like this from within my Django project directory:
gunicorn -b 127.0.0.1:8090 -w 3 myApp.wsgi
Basically I'm wanting to reverse proxy requests to Gunicorn because I can't use mod_wsgi as it can't be compiled for the version of python I am running on my distro of Linux.
I had to do ProxyPass "/server" "http://127.0.0.1:8005/" to get this kind of thing to work it didn't like passing on the root /
I've followed the instructions on Django website for configuring Apache with my Django app on a CentOS 7 server. This included building mod_wsgi from sources to work with the installed python3.4.
Apache restarts without errors but when I hit my app with the URL
http://example.com/myapp/
I get a 503 error like:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Apache/2.2.15 (CentOS) Server at example.com Port 80
I'm not sure how I troubleshoot what's wrong here. Can anyone help?

How to use Django with Apache and mod_wsgi -- follow this: I have done it myself many times, it is very straight forward.
Tip: Create a document and record everything you do whilst setting this up, this way if it doesn't work then you can retrace your steps, but if it does work... Great, you have your very own guide to setting up an Apache server for Django.
Solved my problem (mostly)
The problem is that mod_wsgi with a daemon process tries to write a socket file into the apache logs directory and permissions are denied.
Solution is to tell apache another place to write the socket like this:
WSGISocketPrefix /var/run/wsgi
Although I have found a bunch of tech support to deploy Django over Apache using WSGI but infact they all have confused me unfortunately, and I couldn't get the Django running. I hope this to be real easy job but being a new comer I am facing difficulties.
I have two Django projects namely website1 and website2 inside my /home/zia/Documents/Codes/Django/website1 and ..../website2 dir, respectively. The folder containing settings.py file is root/ inside the /website1 and /website2 dir.
Apache, mod_wsgi everything is installed as required. How to edit apache2.conf and wsgi.py file to keep these two projects running over port 8080 and 8081?
I am struggling with this issue for past few days and have tried all the following websites.
link1,link2,link3,link4
UPDATE1:
I have followed the following approach right from the beginning to make things going well but found myself in some new issues. Kindly guide me where I am wrong.
Installing mod-wsgi and apache2:
sudo apt-get install libapache2-mod-wsgi && sudo apt-get update && sudo apt-get install apache2
Edit the apache2 port to 8083, instead of 80 by altering file "/etc/apache2/ports.conf": Listen 8083
Add the following line into "/etc/hosts" file: 160.75.133.175 160.75.133.175
Edit the following code in the "/etc/apache2/apache2.conf" file:
<Directory />
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
Create a file inside "/etc/apache2/sites-available/" dir with name "sql_api.conf":
<VirtualHost *:8083>
ServerAdmin zia#gmail.com
ServerName 160.75.133.175
ServerAlias http://160.75.133.175

Allow from all
</Directory>
WSGIScriptAlias / /home/zia/Documents/Codes/Django/sql_api/root/wsgi.py

ErrorLog /home/zia/Documents/Codes/Django/sql_api/root/error.log
</VirtualHost>
Run the following commands being in "/etc/apache2/sites-available" dir: sudo a2enmod wsgi && sudo a2ensite sql_api.conf && sudo service apache2 restart
Open http://160.75.133.175:8083/ but getting the following error:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at zia#gmail.com to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
Apache/2.4.7 (Ubuntu) Server at 160.75.133.175 Port 8082
NOTE: When I am making a Django project in /var/www/ dir and then doing the same approach then working just fine! I think because I am trying to access /home/zia/.... dir, there is this issue. Anyways, this is just a guess. I would appreciate your help.
Thanks to everyone. Finally found a working procedure. Follow the following steps in order:
Installing mod-wsgi and apache2:
sudo apt-get install libapache2-mod-wsgi && sudo apt-get update && sudo apt-get install apache2
Edit the apache2 port to 8083, instead of 80 by altering file "/etc/apache2/ports.conf": Listen 8083
Add the following line into "/etc/hosts" file: 160.75.133.175 160.75.133.175
Edit the following code in the "/etc/apache2/apache2.conf" file:
<Directory />
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
Create a file inside "/etc/apache2/sites-available/" dir with name "sql_api.conf" (make as many .conf files you want with different names, each serving different website):
<VirtualHost *:8083>
ServerAdmin zia#gmail.com
ServerName 160.75.133.175
ServerAlias http://160.75.133.175
<Directory /home/zia/Documents/Codes/Django/sql_api/ >

WSGIProcessGroup 160.75.133.175
ErrorLog /home/zia/Documents/Codes/Django/sql_api/root/error.log
</VirtualHost>
Add the following lines in the wsgi.py file inside "/home/zia/Documents/Codes/Django/sql_api/root/": sys.path.append('/home/zia/Documents/Codes/Django/sql_api/root')
sys.path.append('/home/zia/Documents/Codes/Django/sql_api')
Run the following commands being in "/etc/apache2/sites-available" dir: sudo a2enmod wsgi && sudo a2ensite sql_api.conf && sudo service apache2 restart
Open http://160.75.133.175:8083/
you should probably just start over if you made a bunch of changes to your Apache config. I'm most familiar with setups under Ubuntu.
What you need to look to do is setup both sites under apache as a virtual host. After installing apache there is a folder called sites-available and sites-enabled they should contain the virtual host files with the names of your website projects. Each virtual host will point to whereever your .wsgi file is located. these virtual hosts typically listen under the same port number (as Daniel mentioned above) but serve whichever app is requested based on the domain name. noobmovies.com google.com ect...
how to setup a virtual host with apache is pretty well explained here. this assumes you're using ubuntu though.
https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-14-04-lts
your virtual host (the file should be named after your domain exp... noobmovies.com) and will look something like this...
**<VirtualHost *:8080>
ServerAdmin your_admin_email#gmail.com
ServerName www.yourdomain.com
ServerAlias yourdomain.com
<Directory /home/path/your/project/ >
Order deny,allow
Allow from all
</Directory>
WSGIScriptAlias / /home/path/your/project/app/wsgi.py
WSGIDaemonProcess yourdomain.com user=www-data group=www-data threads=25 python-path=/path/to/your/project/app/:/path/to/python/virtual/host/site-packages
WSGIProcessGroup yourdomain.com
ErrorLog /path/to/your/app/error.log
</VirtualHost>**
keep in mind the WSGIDaemonProcess is only if you're running your app using virtualenv (which you should). this tells apache where python is that should be used to read the wsgi app/run django app.
So if you're using ubuntu or linux you may just want to uninstall apache and reinstall then just follow the digital ocean instructions to get setup.
I've installed Apache and mod_wsgi on windows xp service pack 3 and added these line to my httpd.conf :
WSGIScriptAlias / "C:/Documents and Settings/X/My Documents/Downloads/Foo/Foo/wsgi.py"
WSGIPythonPath "C:/Documents and Settings/X/My Documents/Downloads/Foo"
<Directory "C:/Documents and Settings/X/My Documents/Downloads/Foo/Foo">
<Files wsgi.py>
Require all granted
</Files>
</Directory>
but when I open localhost on my firefox, it shows Apache's It Works! message, what should I do to run my project on localhost ?
EDIT :
I checked and recognized that my project's path is not included in PYTHONPATH. Isn't the line WSGIPythonPath ... expected to add the address to PYTHONPATH ?
Alright, so my setup is in linux so this is not tested on windows, but:
I did not see your LoadModule statement
File: httpd.conf
LoadModule wsgi_module modules/mod_wsgi.so
modwsgi wont work without that.
Also: the your grant statement seems a bit suspicious.
In the wsgi configuration guide suggests using a Directory directive for allowing this access to your mod_wsgi application.
<Directory "C:/Documents and Settings/X/My Documents/Downloads/Foo/Foo/">
Order allow,deny
Allow from all
</Directory>
Finally:
Make your life easy down the road.
configure apache in worker mode
configure mod_wsgi in daemon mode.
profit
Might I suggest watching this PyCon talk Making Apache suck less for hosting Python web applications from 'the-man' Graham. I wish I knew all of that stuff years ago.
Note: To figure out if you have apache in mpm worker mode.
httpd.exe -V
look for the "Server MPM" value of worker.
Django runs on port 8000 so you'll want to do two things. First, you need to run the server by entering into your console python manage.py runserver. Second, you need to direct your browser to localhost:8000.
As an aside, you don't need Apache to run a simple, local development environment. Django has its own server built in that you can leverage.
