I'm trying to deploy my Django Project through different application server : Apache2, Nginx/gunicorn, ...
It works fine with Apache2 or Nginx, but I would like to dissociate these application server with my Django Projet. I would like to get an environment like this :
Server 1 (172.30.10.92) : Django Project & wsgi
Server 2 (172.30.10.93) : Nginx/gunicorn
Why ? Because later I will have some Django applications, but I would like to use just one application server.
I think I'm making a mistake with my configuration files syntax.
I have in /etc/nginx/sites-available/DatasystemsCORE.conf :
server {
listen 8000;
server_name 172.30.10.92;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root http://172.30.10.92:/var/www/html/;
}
location / {
include proxy_params;
proxy_pass http://172.30.10.92/unix:/var/www/html/DatasystemsCORE/dscore.sock;
}
}
server_name : Is it IP adress from Django server or nginx server ? I think it's the first one but I'm not sure.
proxy_pass : I think there is an issue in my path
Then, I'm executing this command :
gunicorn --daemon --workers 3 --bind 172.30.10.92/unix:/var/www/html/DatasystemsCORE/dscore.sock 172.30.10.92:/var/www/html/DatasystemsCORE/DatasystemsCORE.wsgi
One more time, I thing there is a syntax problem because I'm getting 502 Bad Request
How I can add IP address from a distant Django server there ?
Thank you !
I found How to solve my issue and I made a tutorial (based on my case) in order to help everyone who would like to make the same thing.
My file is there : Download tutorial file
But this is the same tutorial written in English.
My Django IP server : 172.30.10.92
My Nginx IP server : 172.30.10.93
1- Install and Configure wsgi (located on Django server)
WSGI is a file created with your Django project.
The file is located in /path/to/your/project/Myproject/wsgi.py
We have to edit this file like this :
import os
from django.core.wsgi import get_wsgi_application
import sys sys.path.append('/var/www/html/Myproject')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Myproject.settings")
application = get_wsgi_application()
2- Install and Configure gunicorn/supervisor (located on Django server)
In order to install gunicorn/supervisor, you have to execute in your shell :
pip install gunicorn
pip install supervisor
Then, you have to create a new file in /etc/supervisor/conf.d/Myproject.conf which looks like this :
[program:Myproject]
command = /home/valentin/.virtualenvs/MyprojectEnv/bin/gunicorn Myproject.wsgi:application --name "Myproject" --workers=4 --bind=0.0.0.0:8080 -- user="valentin" --group="valentin" ; Command to start app
user = username #You have to replace by your username
stdout_logfile = /var/log/supervisor/supervisor.log
redirect_stderr = true
log
environment=LANG=fr_FR.UTF-8,LC_ALL=fr_FR.UTF-8
I specified port 8080 which is the communication port between my application server and my web server.
3- Edit hosts file on nginx server (located on nginx server)
You have to edit your hosts file located to /etc/hosts and add a new entry to your Django server :
127.0.0.1 localhost
127.0.1.1 valentin
172.30.10.92 Myproject
# The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
4- New config file in nginx repository (located on nginx server)
This new file should be placed in /etc/nginx/sites-available/Myproject.conf
server {
listen 8080;
server_name Myproject;
root /var/www/html/Myproject/;
location /static/ {
root /var/www/html/;
}
location / {
include proxy_params;
proxy_pass http://172.30.10.92:8080;
}
}
The IP address corresponds to my Django server address. I specified the listen port (8080), the path to my Django project & static directory.
Then, you have to create a symbolic link to sites-enabled.
After ths operation, restart nginx service :
sudo service nginx restart
5- Allow nginx IP address in Django (located on Django server)
You have to edit your settings.py file in order to allow nginx IP address in ALLOWED_HOSTS :
ALLOWED_HOSTS = ['localhost', '172.30.10.93', '127.0.0.1', '[::1]']
6- Finally execute gunicorn (located on Django server)
Finally, you have to start gunicorn. You should be inside your Django root project and execute :
gunicorn Myproject.wsgi:application --bind 172.30.10.92:8080
Now, in your browser, try to connect to your nginx server with the port :
http://172.30.10.93:8080
It works !
PS : This tutorial works for me, if it doesn't work for you, maybe I missed something, or maybe you didn't make exactly like me ;)
What you're trying to do doesn't make any sense. You can certainly use a single nginx on a separate server, but gunicorn is the application server and belongs with the application.
There is no "Django server" so your first question is irrelevant. gunicorn will need to serve on a port, not a socket, and the nginx proxy_pass will point to that port.
I installed WAMP server and ran the applpication. The icon in the taskbar stays orange and says "local server - 1 of 2 services running" . Also, I am able to see the phpMyAdmin page in the browser but when I try to login it gives the following error:
#2002 - No connection could be made because the target machine actively refused it. <br />The server is not responding (or the local server's socket is not correctly configured).
I have tested port 80 and I got this response:
***** Test which uses port 80 *****
===== Tested by command netstat filtered on port 80 =====
Test for TCP
Your port 80 is used by a processus with PID = 6612
The processus of PID 6612 is 'httpd.exe' Session: Services
The service of PID 6612 for 'httpd.exe' is 'wampapache64'
This service is from Wampserver - It is correct
Test for TCPv6
Your port 80 is used by a processus with PID = 6612
The processus of PID 6612 is 'httpd.exe' Session: Services
The service of PID 6612 for 'httpd.exe' is 'wampapache64'
This service is from Wampserver - It is correct
===== Tested by attempting to open a socket on port 80 =====
Your port 80 is actually used by :
Server: Apache/2.4.18 (Win64) PHP/5.6.19
I believe that the above result means that there is no problem with the port. I even tried changing the port and still gives the same status - orange icon.
Note - When a prompt from Windows Firewall was shown after installing WAMP, I didn't give access to both private and public networks, i.e. I unchecked both the options.
Kindly help me to run both the services in the local server.
Thank you!
Click on the WAMP icon in the tray and go to Apache > service Administration and check if the service is installed or if it isn't running . You can even reinstall it by removing and installing it again. Do the same with MySQL . Go to MySQL > Service Administration and do the same things . In my case Apache service wasn't installed and Installing it did the trick. check the image below.
See this image
Most of the answers given on the Internet say to change the port used by Apache but that is not the solution in most of the cases.
Actually, start the WAMP server->right click on the icon -> tools -> use a port other than 3306 -> click on this -> set on 3308.
Hopefully, this will resolve the error.
I had the same problem but only Skype was using port 80. I just changed port 80 from Skype and make it use another one. OR you can change port 80 used by Apache. To do this go to WAMP -> Apache -> http.conf and change Listen 80 with Listen 81 for eg.
The same with me but in my case I installed mysql after installing wampserver so there was a port conflict between the integrated version and the independent version of mysql for the port 3306, so the problem could resolved either by changing one of ports
If you want to change wampserver's mysql's port go to the taskbar icon right click and the go to tools select: use a port rather than xxxx(3306 in my case)
This thread helped me.
How to change port number for apache in WAMP
Thread Details below
Just go to httpd.conf file, for ex. under WAMP environment its situated at:
C:\wamp\bin\apache\apache2.2.22\conf\httpd.conf
go to line no. 46 and edit Listen 80 to your requirement for ex.
Listen 8383
newer versions of WAMP uses these 2 lines:
Listen 0.0.0.0:8383
Listen [::0]:8383
Next go to line no. 171 and edit ServerName localhost:80 to your requirement for ex.
ServerName localhost:8383
Restart Apache and its done !!
Now, you can access with your URL:
http://localhost:8383 or http://192.168.1.1:8383
Hope it helps to people looking for solution here.
No need to remove and reinstall WAMP or edit Host file or change any port. this problem happens when Internet Information Services (IIS) Manager service is running. you need just stop IIS to run wampapache service without any problem.
press start then type iis and run Internet Information Services (IIS) Manager and in right panel press stop. then click on wamp icon on system tray and choose start all services.
this is all you need.
I had the same issue some time back. Tried all kinds of things and finally found the link below. Basically the issue was:
A parameter in your 'my.ini' file (C:\Wamp\bin\mysql\mysql<version>) called 'lower_case_table_names'
If there, comment it out and restart MYSQL again."
If I recall, also did a computer restart also just for good measures.

This might be because php is not working because the default port 80 is taken so u need to change the port follow these steps
1. Click the wamp icon from the bottom right corner
2. Go to Apache->httpd.conf and open this file
3. Search for word Listen in the file and change these two lines
Listen 0.0.0.0:8018 (u can use any digits instead of 18 )
Listen [::0]:8018
4. Now search for the word localhost and change this line
ServerName localhost:8018
5. Restart wamp
6. Go to your default browser and type http://localhost:8080/ this will open the wamp menu
It's either your WAMP Apache port is clashing with IIS (if that is installed and running), or MySQL port is clashing with another MySQL install.
Edit your WAMP > Apache > httpd.conf by hovering cursor over Apache inside WAMP tray icon. Change port 80 to an available port like 8181. Restart all services.
I had the same issue, where only 1 service out of 2 was running. But my issue was not a port issue.
I had previously zipped up a bunch of .conf files in the alias directory to share them with a colleague, and I left the .zip file there. This caused an error in Apache as it tried to use the .zip file as an alias.
Once I removed the .zip file from the alias directory, my Apache services were working fine.
Bit of an 'outside the box' answer, but this was my issue with the same symptoms!
Maybe it is not a port problem.
if you had a problem because msvcr110.dll is missing
so after you setup the library you will get this problem service 1 of 2
so in this case you have to reinstall the wamp server.
I had faced similar similar issue where the server was not starting up with the following message - "local server - 1 of 2 services running" , with server icon in Orange color.
With nothing updated in the error logs. Finally was able to track issue through -
Wamp server icon -> Apache -> Service Administration 'wampapache64' -> install service
Error message : WAMP - 'Your port 80 is actually used - Error'
Resolution : Change the port number of the wamp server to some other number,for example 5050.
Go to: C:\wamp\bin\apache\apache2.4.9\conf\httpd.conf
In that file change the listen port to 5050.
#Listen 12.34.56.78:5050
Listen 0.0.0.0:5050
Listen [::0]:5050
Save and Restart. Now you can see the server started successfully with green icon.
Following threads helped me to resolve this issue :
How to change port number for apache in WAMP
WAMP - Your port 80 is actually used - Error
GO to run type Services and enter
check these two services must start
I've installed Apache 2 through the Bitmani Django stack and when I access the localhost it works fine, but when I enter the public IP it loads for a bit and then presents that error.
The apache server is running and I have the conf file set to listen on port 80.
What could be going wrong?
I am installing wamp server 64 bit on my windows 8 system.I get following error "Application was unable to start correctly ( 0*c00007b)"
1) I have not installed the Skype
2) Port 80 is not being used by any program.
3) IIS service is not running on my system
4) I have tried re installing the wamp also
See screenshots
Following is there in C:\Windows\System32\Drivers\etc\hosts
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
How to fix this.
Even though I start wamp server the icon never turn to green.
Do I need VC++ Redistributable?
Solution
I followed shiva's answer and installed 32 bit version.
Hope some one will post correct solution for this issue.
you can install TCPView to find out that which service is using the post number 80, and close it and then run Apache(if something is using it).
alternately you can edit the httpd.conf file and change the port number ,by default it can be found at this location
C:\wamp\bin\apache\apache2.2.22\conf\httpd.conf
In it go to the line which has this entry(line 58 in WAMP server 2.4's installation)
Listen 80
and change it to something like this Listen 8080, and restart WAMP(or specifically Apache).
Now you will be able to access localhost like this
http://localhost:8080
Update 1
According to this forum post, installing 32-bit version in place of 64 bit version,solved the issue in some cases
WAMP changed port 80 to 8080 in Apache > httpd.conf but the application link won't update from localhost to localhost:8080
And so I have to type :8080 when starting the application over and over again...
The Question is:
Is there any way to make wamp application link to localhost and localhost/phpMyAdmin to localhost:8080 and localhost:8080/phpMyAdmin so I don't have to type this all the time ?
Thx :)
Edit c:/wamp/wampmanager.tpl file so the WAMP menu points to localhost:81.
Find http://localhost and change it to htttp://localhost:81
also, if you think something else has already grabbed port 80, that is why its not working..,then,
Run wampmanager->Apache->Service->Test port 80
This will launch a command window and tell you what is using port 80.
Whatever it is will need to be re-configured to use another port or for example if its IIS and you dont use IIS it should be un-installed.
