Re: Issue with Python 3.6 and Django 2.0 App Deployment on Shared Hosting

Hi Corey,

I'm having what seems to be the exact same problem with django/fcgi on bluehost shared hosting (getting a 404 in the browser but the appropriate html on the command line; I posted my question here), so I'm wondering if/how you ended up resolving it.  Any tips would be greatly appreciated, thanks!!!

Thanks a million for your fast response! I greatly appreciate it. I have made those changes you recommended. I swear I looked at that a million times and couldn't see a difference. Thanks for pointing that out.  I also added to my settings file under templates the word 'INFO' rather than 'DEBUG' and I am able to get my debug.log file to simply now say: 

    Not Found: /

These changes are definitely getting me closer. Thank you! I still see the standard 404 page, however, and not the Django 404 page. If I run app.fcgi in my shell I still get all of the Django-specific html but the following errors remain:

WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!

WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!

WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!

WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!

I have tried looking at my fcgi_base.py which is where this error is coming from to see what I should modify:

The following code there states:

 for name,default in [('REQUEST_METHOD', 'GET'),

                             ('SERVER_NAME', 'localhost'),

                             #('SERVER_NAME', '50.87.249.197'),

                             #('SERVER_PORT', '33606'),

                             ('SERVER_PORT', '80'),

                             ('SERVER_PROTOCOL', 'HTTP/1.0')]:

 if name not in environ:

                             environ['wsgi.errors'].write(bytearray('%s: missing FastCGI param %s '

                                                       'required by WSGI!\n' %

                                                        (self.__class__.__name__, name), 'utf'))

                             environ[name] = default

That IP I believe is what bluehost recommended me to use but they can't assign me a port because I am on a shared server. When I type in:

netstat --listen

I can see the open ports and 33606 should be open...

I have tried commenting on the code lines above and trying my specific IP and and my port that I believe is open, but the result is the same.

Do you by chance see anything else I can try. If you would like I would be more than happy to send you any information you request that you think may be helpful in resolving this. Again, Thank you for your time and help! I greatly appreciate it!

Best wishes!

Corey

Looking at the .htaccess file and the example provided here:  https://docs.djangoproject.com/en/1.8/howto/deployment/fastcgi/#running-django-on-a-shared-hosting-provider-with-apache

It looks like you have a typo.

AddHandler fastcgi-script .fcgi

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L]

 

In the RewriteRule line, you have a % instead of a $.

 

Also, your DJANGO_SETTINGS_MODULE doesn't have your project name specified.

 

Granted, these examples are from Django 1.8.

Hi! I am having the same problem. Did you get this to work yet? Any tips would be greatly appreciated:

 

I am using a shared server, linux, Django 2.0, Python 3.6.4, flup6. Because fastcgi is deprecated post Django 1.8 and Bluehost doesn't use WSGI and only FastCGI (mod_fastcgi) I am using what NetAngels made available: https://github.com/NetAngels/django-fastcgi

My .htaccess file is the project folder with my .fcgi file as is commonly recommended. My .htaccess reads:

AddHandler fastcgi-script.fcgi

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^(.*)% app.fcgi/$1 [QSA, L]

My .fcgi file reads:

#!/homeX/user/python3.6/bin/python36

import sys, os

project_name = "app"

sys.path.insert(0, "homeX/user/python3.6/bin/python36")

sys.path.append("directory/of/my/project/app")

sys.path.append("directory/of/my/project/app/app")

sys.path.append("directory/of/my/project/app/app/app")

sys.path.append("directory/of/site-packages")

sys.path.append("directory/of/site-packages/flup")    

sys.path.append("directory/of/site-packages/django")  

os.chdir("directory/of/my/project/app/app/app")

os.environ['DJANGO_SETTINGS_MODULE'] = "settings"

from django_fastcgi.servers.fastcgi import runfastcgi

from django.core.servers.basehttp import get_internal_wsgi_application

wsgi_application = get_internal_wsgi_application()

runfastcgi(wsgi_application, method="prefork", daemonize="false", 

minspare=1, maxspare=1), maxchildren=1)

I have made sure to:

chmod 0755 app.fcgi

I am able to type into the linux SSH:

app.fcgi

This is what comes up in the SSH terminal:

WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!

WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!

WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!

WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!

Using the URLconf defined in <code>app.urls</code>,

Django tried these URL patterns, in this order:

</p>

<ol>

<li>

admin/

<li>

million/

</li>

</ol>

<p>

The empty path didn't match any of these.

<div id="explanation">

<p>

You're seeing this error because you have <code>DEBUG = True</code> in

your Django settings file. Change that to <code>False</code>, and Django

will display a standard 404 page.

</p>

</div>

</body>

</html>

However, when I go to my website.com/app it shows me the standard 404 error generated by my host. If I go to my website.com/app/app.fcgi it shows me the contents of the file and not the HTML generated when I run app.fcgi. In the main settings.py file,

DEBUG = True

ALLOWED_HOSTS = ['*']

But it will not show me the error generated by Django. I have tried putting in host information, socket information, etc. and it always give me a 500 error when I go to my website.com/app.

I have messed around trying to connect FastCGIExternalServer to my .fcgi file but I can never get the HTML as when I simply just use the default settings that I get from NetAngels referenced above, despite the WSGI warnings. It seems that because it is outputting my HTML, that everything is fine (i.e., it will still display my HTML) because if I try to correct for the WSGI warnings/errors, I don't ever see any of the HTML that Django is generating which is below the WSGI errors.

I was able to get a debug.log working and this is what it says:

HI All, 

 

I'm a very new into web development as well as very recently started with Python 3.6.4 and Django 2.0 and built my first web application successfully. Currently I'm in the process of deploying the web-app on a shared hosting environment on Bluehost.  

 

I was able to configure both Python and Django latest versions successfully on Bluehost server using virstualenv and was able to create my test-app ass well on the server directly using SSH client. 

 

Where I'm stuck right now is to make this app work on my domain. I have explored everything on google and tried everything possible from my side but with no luck in the end. Ever time I try to access my website in my local browser, I get the following error message: 

 

500 Server Error

A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again.

 

I understand that it may not be sufficient information for anyone to help me with. I'm very new to this whole process of community and forums etc, so please let me know in case if you look for any additional info in this regard. 

 

I will greatly appreciate any help or pointing me into the right direction. 

 

Alok.
