Hello I coded this website that generates math problems (Here is the code: Here)
It is coded on flask and it is locally being hosted on this link that is not accessible to other people http://127.0.0.1:5000/ .I have a google domain and I want to have a website. What things / services do I need to use. I have been wait to see if I need to use AWS but I think I might need to. I have tried things like transferring it off of flask but I can't. If this is a repost sorry please post there answer thanks -Ben
I am assuming what you're asking is to host your flask web site so others can view it. The address you mention in your post is the local host address for your computer and is only accessible from your own computer. If you only want someone on your same network (WiFi) to access it, you would need to replace "127.0.0.1" with the IP address of your computer. You would also likely have to open up a firewall on your computer to allow the port 5000.
However, if you want anyone on the internet to access your site, there are a ton of ways to do this but since you mentioned AWS, you can do this easily by running a small EC2 instance (virtual server). If you have a new AWS account and have not already run any EC2 in that account, you can actually run a small EC2 instance for free for a whole year. Great for small projects. If you're just getting started with EC2, you may want to go here https://aws.amazon.com/ec2/getting-started/
Basic steps:
Spin up an EC2 instance. Choose the default Amazon Linxu 2 OS type, make sure to create/assign a key pair so you can later ssh into it, make sure the Allow SSH from anywhere setting is checked/selected and the Allow HTTP checkbox is checked (not HTTPS).
Wait for the instance to launch.
Log into your instance by clicking on your ec2 instance in the list of ec2 instnaces and click the Connect button, click the Connect button again (Instance connect tab). If that doesn't work, follow the steps on the SSH client tab.
Install flask
pip3 install flask
Clone your git repo
git clone https://github.com/some0ne14/Math-Ibex.git
Change to your repos' folder
cd Math-Ibex/Math-Practice-Website-master
Edit your main.py so that the app.run line looks like the following (you can do this on GitHub before you run git clone actually or use the nano command to edit the file easily). This allows the system to run on the standard web port 80.
app.run(host='0.0.0.0', port=80, debug=True)
Run the following to start the application. If you want to run it as a service so you can walk away or close the terminal and it will still stay running, just search on here how to run flask as a service.
python3 main.py
You can now connect to your server with any web browser using your EC2 instance's public IP address or generated AWS DNS name (available on the EC2 instnace property page).
Make sure to stop your instance when not using it to save those free runtime minutes.
I made a WEB application using Bottle and want to publish it. I decided to use paste for the web server because official document said it's the easiest way.
In order to let the web server process listen on the port 80, the process must be launched by the root user. I'm not a security expert and can not judge that it's safe to use the root user for launching an application that is exposed to the internet directly.
Shall I avoid using root user in such a situation ?
No.
Do not run your web server as root.
Shall I avoid using root user in such a situation?
Yes, avoid running as root.
In order to let the web server process listen on the port 80
Your web server does not need to listen on port 80. One common way to structure this is to put a proxy (like a load balancer) in front of your web server. Your server listens on a non-privileged port (e.g. 8000); the load balancer (which is listening on port 80) forwards all requests to your server.
The accepted answer (which does not actually answer your question) merely mentions chroot, but I suggest that you not worry about that. Running as a non-privileged user is a much more important safeguard than using chroot. I would consider chroot to be secondary to your initial, quite legitimate, concerns over running as root.
It is recommended to create an chrooted environment with an restricted user.
Over here you can find a howto on how to create a chrooted environment www.howtogeek.com/441534/how-to-use-the-chroot-command-on-linux/amp/
I'm trying to test and distribute my python application in script or executable form (client). I already have my openshift server setup and running. I'm confused on setting up port forwarding with other users to test it out with.
Do other clients (publicly) need to download rhc and run 'rhc port-forward appname' on their own machine or are there alternatives out there which can be accomplished using python internally by code?
This is kind of confusing and any help would be much appreciated.
Thanks.
all the 'rhc port-forward appname' does is set up SSH tunnels behind the scenes. If you want people to tunnel into your appication you will need to get their public SSH key into your application as an approved key. Then you can set up an SSH tunnel whatever way you chose.
How can I deploy cherrypy along with IIS. I am not able to reach the machine from outside using the IP. If i run using localhost it works. If I give the ip address in the browser from a different machine then IIS7 comes up.
Thanks
Raman
It would help if you posted more information about your problem but this kinda sounds like a classic configuration issue. If you have CherryPy listening on localhost (127.0.0.1) then it will only answer on that address. You have to configure it to listen on the external IP address if you want it to answer there. Here is another question that covers how to do this.
It also sounds like you are trying to run CherryPy on a box that also has IIS7 running. If this is the case, and you wish to continue to run both, you will either need to configure CherryPy to use a different port than IIS7 or you will have to configure IIS7 to redirect requests to CherryPy. Here is a similar question about doing the latter with IIS6
I'm currently trying out the Django framework and I would share/present/show some stuff I've made to my workmate/friends. I work in Ubuntu under Win7 via VMware. So my wish/desire is to send my current pub-IP with port (e.g http://123.123.123.123:8181/django-app/) to my friends so they could test it.
the Problem is - I use django's Dev server (python /path-to-django-app/manage.py runserver $IP:$PORT).
How do I make the devserver public?
EDIT:
Oh, there's something I forgot to mention. As I sad I use VMware with Ubuntu. I have a shellscript that returns me my current int-IP 192.168.xx.xx and saves it in a environment-variable ($CUR_IP)
So, each time I want to run django's devserver I simply execute
python /path-to-django-site/manage.py runserver $CUR_IP:8080
At this way I become an http-adress (e.g.http://192.168.40.145:8080/app-name/) which I CAN USE OUTSIDE my virtual machine. I could test it on my host (win7) machine. That's actually the reason why I asked the question. I thought there's a way to use the ext-IP and make runserver usable outside too
python manage.py runserver 0.0.0.0:8181
This will run development server that should listen on all IP's on port 8181.
Note that as of Jun 17, 2011 Django development server is threaded by default (ticket #1609).
From docs:
Note that the default IP address,
127.0.0.1, is not accessible from other machines on your network. To
make your development server viewable
to other machines on the network, use
its own IP address (e.g. 192.168.2.1)
or 0.0.0.0.
Assuming you have ruby installed, you just have to get localtunnel:
gem install localtunnel
then start your python development server with:
python manage.py runserver 0.0.0.0:8000
in another shell, start localtunnel:
localtunnel -k ~/.ssh/id_rsa.pub 8000
That will output an url to access your local server.
Port 8000 is now publicly accessible from http://xxxx.localtunnel.com
That's it.
192.168.*.* is a LAN-private address -- once you've done the proper VMWare (or other VM manager) and firewall incantations to make it accessible from the LAN, it still won't be accessible from outside the LAN, i.e., from the internet at large (a good thing too, because such development servers are not designed for security and scalability).
To make some port of a machine with a LAN-private IP visible to the internet at large, you need a router with a "virtual servers" ability (many routers, even cheap ones, offer it, but it's impossible to be specific about enabling it since each brand has its own idiosyncratic way). I would also recommend dyndns or other similar service to associate a stable DNS name to your always-varying public IP (unless you're splurging for a static IP from your connectivity provider, of course, but the latter option is becoming costlier all the time).
superuser.com or serverfault.com may provide better answers and details (once you give every single little detail of your configuration in a question) since the question has nothing much to do with software development and everything to do with server administration and configuration.
I had to add this line to settings.py in order to make it work (otherwise it shows an error when accessed from another computer)
ALLOWED_HOSTS = ['*']
then ran the server with:
python manage.py runserver 0.0.0.0:9595
Also, make sure that your firewall allows communication to the chosen port (9595 in this case)
Already answered but adding npm alternate of same localtunnel
sudo npm install -g localtunnel
lt --port 8000 --subdomain yash
If you are using Virtualbox, You need to change the network setting in VB from "NAT" to "Bridged Adaptor". Then restart the linux. Now if you run sudo ifconfig you are able to see your IP address like 192.168.*.* . The last step is runserver
python manage.py runserver 192.168.*.*:8000
Cheers!
You need to configure bridged networking in VMWare and also grant access to the target port in Ubuntu firewall.
Alternatively, you can use cotunnel, Just run cotunnel in your ubuntu (in VMware) change your tunnel port in cotunnel dashboard which port you are using in local side. It gives public url and you can share the url with your friends.
Your Django server can listen to 127.0.0.1 or 0.0.0.0 (I prefer 0.0.0.0) it does not matter for cotunnel.
Might I suggest trying something like pyngrok to programmatically manage an ngrok tunnel for you? Full disclosure, I am the developer of it. Django example here, but it's as easy as installing pyngrok:
pip install pyngrok
and using it:
from pyngrok import ngrok
# <NgrokTunnel: "http://<public_sub>.ngrok.io" -> "http://localhost:8000">
http_url = ngrok.connect(8000)
No messing with ports or firewalls or IP addresses, and now you can also inspect the traffic (which is useful since what you're doing here is ongoing development, not running a prod-ready server).
