I've created a Python web app using CherryPy, and have deployed in on my local machine.
When I try to view it from another computer in the house, nothing comes back.
However, if I create a simple html file, and deploy it with:
$ python -m SimpleHTTPServer
It is visible over the intranet.
I'm stumped as to why my app could work locally, but not be avalable over the intranet, given that there is not a connection problem between these machines, and that I can serve other content on the same port.
I have not used a configuration file, I'm using the default CherryPy settings.
The default settings likely bind to localhost, which is not publicly available. If you want CherryPy to run on a public interface, you'll have to direct it to do that. From this discussion I found:
cherrypy.config.update(
{'server.socket_host': '10.149.4.240' } ) # Pub IP
cherrypy.quickstart()
or
cherrypy.config.update(
{'server.socket_host': '0.0.0.0'} )
cherrypy.quickstart()
To bind to all interfaces.

I have a Flask app running with a cert/key created in openssl:
app.run(host="192.168.0.2", port=8000, debug=True, ssl_context=('/certs/fullchain.pem', '/certs/privkey.pem'))
The Flask app is being served on IIS via FastCGI.
The actual website is using a .pfx created with the same fullchain.pem and privkey.pem files from openssl.
When I use the Flassk app (api) from the web app (ajax call) in Opera, everything works as expected... but when attempting to use it from any other browser, I get ERR_CERT_COMMON_NAME_INVALID.
I thought it may be due to the Flask app using 192.168.0.2 VS the "example.com" the cert is assigned to, but I have no way around this. Certs cannot be assigned to raw IPs.
Any suggestions would be GREATLY appreciated, thanks!
I am new to Python development. I am building a test Python app and already deployed into a web server and accessing it through public IP. Now I have updated the source(that is added some more models and templates), Now I want my public IP under port 80 should show updated code.
How do I do this?
if you have used any sort of version control, it's just commit and push/pull to the server.
if not, you have to copy the code, paste it in the server, restart the application and it work's with new code.
best approach is make a service, deploy the code with git version control, run the service and you are good to go. service will start automatically in case of system-restart and such.
I want to deploy my flask web application on Azure cloud. In Deployment options, I have selected GitHub as source destination for my flask code. after doing the configuration test successfully, the init.py file now starts building;
Now when I go to my application link, it shows me this;
Now at this point, I went back to my deployment options, it says Building failed;
the log generated for this building failed can be seen in the first picture. All the tests has passed except the last one "Performance test". Have anyone encountered the same issue before ? what can be the reason for that ?
I am running the application on localhost # port 8000.
from flask import Flask
app = Flask(__name__)
#app.route("/")
def hello():
return "Hello World!"
if __name__ == "__main__":
app.run()
Do I need to run it on another IP ?
You cannot listen on port 8000 in Web Apps. Only port 80 or 443. You'll need to read the port number from the environment, to know what to listen on.
If you created the Azure Webapp using the Flask tool, the default app is called FlaskWebProject1. If your app has a different name, you need to modify web.config in your wwwroot folder to reflect the correct app name.
Then redeploy using the Azure portal or change it in your GIT and push again.
Based on your 500 error, I think some python packages are not installed correctly.
To check your code is working correctly in naive manner, do as follows.
If you are developing on Windows machine, copy all of your site-packages files in development machine to WebApp /site/wwwroot/env/Lib/site-packages folder.
Hit Restart in Azure Portal and F5 in browser.
If it works, your deployment process might have a problem. Mainly it is caused by library installation.
First, check you have requirements.txt at the root folder. This documentation describes some considerations to load Flask on Azure WebApp. Of course, it would be really helpful to read the documentation from the first line carefully.
Second, login WebApp via FTP and check the package is installed correctly. You can see /pip folder has pip.log file, and /site/wwwroot/env/Lib/site-packages folder has its libraries.
For some libraries which you might require more than simple hello world app, you may have to push x86 .whl files along with python codes as they are not installed correctly in x86 environment.
Additionally, in order to show internal error to outside, consider to apply this option during development (not for production).
I created a Django Python application in localhost and setup virtualenv for running python application. I run this application from terminal and can access with this url- http://127.0.0.1:8000/ . On hosting time (server) how can i access this application using url?
I suggest you to check out this page of the django documentation if you haven't already: https://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/
Deployment of a web application is not as easy as running the python development server, that is extremely simpler and is discouraged to be used on a server by the django documentation itself.
On a theoretic point of view, the reason why you can't access remotely the development server is because it binds the server on local only access: to make it accessible from an external computer you need to bind it to listen on 0.0.0.0 instead of 127.0.0.1, then you will be able to reach it on example.com:8000 depending on what the server's domain is and what port you choose. To use 0.0.0.0 you call manage.py runserver like this:
./manage.py runserver 0.0.0.0:8000
but avoid to do it, and opt for a more robust deployment :)
If your trying to deploy your application for the first time, and you want to get a feel of accessing your app from url, try heroku, https://www.heroku.com/
Easy and you don't have to worry about setting up everything.
I'm learning Django and working on sample sites.. I registered at alwaysdata but am unable to view the site after I go 'manage.py runserver' in the SSH (this is after I've created the project and navigated to the appropriate directory, of course).
I appreciate any help.
Thanks
Have you taken a look at the wiki entry regarding the django dev server? Google translate seems to indicate that you need to request some ports open first, and that once you've got them assigned you can pass in one of those port numbers to runserver to run it on that port.
If you need the translated-to-English version, here's a link
I am also an alwaysdata customer. Daniel DiPaolo gave you the right links to get it working on ssh with the dev server. The google translation seems correct to me. You need to request a port range in order to use the dev server on ssh.
But this is intended only for debugging purpose and should run for a short while.
Here is how to deploy with fastCGI which is the regular way to deploy a Django site on alwaysdata.
http://wiki.alwaysdata.com/wiki/D%C3%A9ployer_une_application_Django.
Google give a decent translation
AlwaysData is running a forum at http://forum.alwaysdata.com/ mostly in French but questions in English are welcomed.
The devserver included with django is for testing purposes, only on your local machine and should not be used on a web host. From the docs:
DO NOT USE THIS SERVER IN A PRODUCTION
SETTING. It has not gone through
security audits or performance tests.
(And that's how it's gonna stay. We're
in the business of making Web
frameworks, not Web servers, so
improving this server to be able to
handle a production environment is
outside the scope of Django.)
If i have somehow misinterpreted your question, i apologise.
When you enter manage.py runserver you're running the development web server on the loopback interface (127.0.0.1). You could test this out by running wget 127.0.0.1 on the same server that the development web server is running.
If you want it to be on the internet so you could access it from outside that server, you'd have to specify your public ip. For example, to run the web development server on ip 1.1.1.1 and port 8080 (personally recommend using a non-standard port):
manage.py runserver 1.1.1.1:8080
To find out your public ip, try running ifconfig on SSH.
Also, you might have to check out the firewall settings with your ISP/server provider.
