I am trying to create new custom module in drupal 8 . I got given below logs . and system is not responding now . I am unable to logged in in drupal 8 site .
Log is given below :-
[Mon May 01 19:15:28.999581 2017] [:error] [pid 1892:tid 1660] [client ::1:60090] Uncaught PHP Exception Symfony\Component\Routing\Exception\RouteNotFoundException: "Route "first_module.content" does not exist." at D:\PHP server\xampp-win32-5.6.30-0-VC11\xampp\htdocs\drupal_8\core\lib\Drupal\Core\Routing\RouteProvider.php line 187
Which files have you created for custom module. Drupal 8 requires only 1 file as a start.
custom_module.info.yml
name: Custom module name
description: 'Module Description'
type: module
core: 8.x
package: Custom
You have a route "first_module.content" in your code which is not available.
Make sure the route exist in your first_module.routing.yml and you have cleared your cache.
If the website is not responding and you are not able to clear cache, go to your database and TRUNCATE all the tables with prefix 'cache_'.

Problem
I am running apache2 on my local ubuntu server. I set up a Django project using django-admin startproject site and set up my virtual host to use a WSGI Daemon process to run the Django project. This worked and the site is accessible through its IP 192.168.1.3.
When I go to /admin, it allows me to log in and see the initial backend but loads for 5 minutes then goes to a 500 error when I click anything or reload, even when trying to access the non-admin index page. This persists until I run systemctl restart apache2 and completely restart apache or wait ~10-15 minutes until it fixes itself (only to break again immediately if I access /admin pages).
Versions
Django version 4.1.5
mod-wsgi version 4.9.4
My Attempts
If I run the project with python manage.py runserver, I can access it on 192.168.1.3:8000 and fully use the /admin backend, even creating new users, etc. I then thought it was the WSGI Daemon process somehow messing it up, so I followed the linked section of this page: https://pypi.org/project/mod-wsgi#using-mod-wsgi-express-with-django and ran the site with python manage.py runmodwsgi. The site completely works on 192.168.1.3:8000 along with the /admin, and I can create new users etc., which points to it having nothing to do with the WSGI setup (as well as the non-admin pages working fine on the virtual host WSGI).
I have fully deleted and restarted the Django project, as well as setting up new virtual host .conf files with the proper WSGI information, etc.
I read about an /admin loading issue back in Django 3.0, but I am on 4.1 so that is unrelated.
I am at a complete loss at what the issue could be at this point. Why won't my /admin section work on the virtual host??
EDIT:
The issue is actually definitely the WSGI somehow. I am getting this is my apache error log:

I still do not know what the solution is, though.
https://forum.djangoproject.com/t/django-apache-deployment-not-working-as-intended/15800
I found the solution. Somehow during the whole setup, adding WSGIApplicationGroup %{GLOBAL} to the /etc/apache2/apache2.conf file was never recommended, at least not that I noticed, but it worked and all the admin functionality works on the virtual host through WSGI Daemon.
Hope this can help someone else.

Is any one installed memcache module in drupal 8 ? Please let me know I am getting errors while installing memcache moule.
Error is :-

Yes. We can integrate memcache with Drupal 8. And it works perfectly fine.
From your error, it seems that in one of your module, there is a syntax error in yaml file. Extra tab is there. It is not evident from your posted error that the issue is with memcache module.
Check in your custom module's yaml file for extra tab at line 8.
This could resolve the issue.
I assumed this would not be possible, but after reading this post thought that perhaps it might be:
How can I send data from a web page to a serial port?
So I added my code for serial as below and just hoped some sort of magic would occur:
import serial
ser = serial.Serial('/dev/ttyACM0', 9600)
As expected though, I got an error:
[Mon Aug 01 07:01:44.513340 2016] [wsgi:error] [pid 16:tid 140515737831488] raise SerialException(msg.errno, "could not open port %s: %s" % (self._port, msg))
[Mon Aug 01 07:01:44.513367 2016] [wsgi:error] [pid 16:tid 140515737831488] SerialException: [Errno 2] could not open port /dev/ttyACM0: [Errno 2] No such file or directory: '/dev/ttyACM0'
The code is working fine locally and the online environment mimics the modules available locally through requirements.txt.
Not directly what you want to hear. But the answer is no. You cannot use pySerial remotely unless you your webservice running locally on target computer.
But anyway you can still achieve your goal by using one of following approaches (in order of complexity for client):
Java applet or Java Web Start application (for example there is a good cross-platform library RXTX)
Browser plugins such as jUART, browser-serialport or serial for google chrome or even ActiveX component
Serial port to network proxy (like ser2net).
The only problem is that your clients will still need to do additional steps in order to your site could properly work (install java/native library/allow applet/browser plugin or additional software). The reason for that is because browsers are very restrictive and by default all filesystem operations are sandboxed by default for security reasons.
Setting up my first app. I started on the django development server, and am now moving things to an apache setup so that I can code in my target prod environment. I've gotten mod_wsgi set up successfully and got a successful "Hello World!". Now I'm having issues actually getting my app to respond in apache the way it did in the django dev server.
Here's my directory structure:
/var/www/www.example.com/ [site directory]
Example [my app]
wsgi.py
settings.py
users [another django module i wrote]
trips [yet another django module i wrote]
Now, in my virtual host file, I have the following line:
WSGIScriptAlias / /var/www/www.example.com/Example/wsgi.py
And in my wsgi.py file, I have the following lines:
sys.path.append('/var/www/www.example.com/Example')
sys.path.append('/var/www/www.example.com/trips')
sys.path.append('/var/www/www.example.com/users')
Yet, here's the error I'm getting:
[Sun Jan 06 21:37:46 2013] [error] [client 127.0.0.1] ImportError: No module named trips
What do I need to do to get django and mod_wsgi to recognize my trips and users apps?
Thanks!
don't add every module to sys.path.
Instead you should add /var/www/www.example.com to sys.path.
I am running Django site in Apache with mod_wsgi.
The site works before. Today when I am try to install a tokuwiki on the same server, I found the site become failed that when I open the django site, the chrome always loading and after a long long time it say "no data received".
The django site works on my development machine and another virtual machine.
On the amazon ec2:
When I use wget on static files (.css, .img) served by apache, it received normally.
But when I use wget on dynamic page from django, it stoped at awaiting response... , which means the problem is on the django + apache part.
I check the apache log that each time I refresh the browser, it will loading the django setting again, but nothing else. The log shows it did not enter the view function (I am not sure whether it entered the url routine or not):

[Sat Nov 19 02:15:54 2011] [error] Using Amazon Server Settings
I tried to uninstall tokuwiki, reinstall apache, mod_wsgi, django. Rewrite the apache configure file.
Other information:
I opened the Debug mode of Django, and when I visit a not exist page, Django's page not found error page showed on the browser.
When I open the django's admin console mysitename/admin/ , browser also did not received any data.
Any clu where to check next?
Finally, found the problem is caused by scipy package.
And then I found a similar problem asked by other people.
