The initapp style of initialization is also supported. To start the web server simply execute your script. Note the way the web server is started. The socketio.run function encapsulates the start up of the web server and replaces the app.run standard Flask development server start up. https://venzine.weebly.com/mac-ntfs-paragon-vs-tuxera.html. When the application is in debug mode the Werkzeug development server is still used and configured. FLASKAPP=file.py: If you have your application in a Python file, you can simply set the name of the file, and Flask will import it and find the application using the same rules as in the previous option. If FLASKAPP is not defined, Flask will attempt to run import app and import wsgi. If either of these succeeds, it will then try to find the application in the imported module using the same rules as the.
Flask is a (micro) web development Framework for Python. It is fairly simple to get started. All you need to do is to
pip install Flask
into your virtualenv, give the FLASK_APP environment variable your file and run flask run
(described in detail in installation and quick start). This will launch the development server and you can instantly start hacking around.When you want to use your Apache webserver, however, you need to install and configure a WSGI module. When I first wanted to do this I tried to install mod_wsgi via brew (
brew install mod_wsgi
from the homebrew/apache tap), but quickly ran into some (apparently common) issues with the XCode toolchain. Then I discovered that there is a much easier way of installing mod_wsgi as a Python package.On the PyPI page it says…
[it] will compile not only the Apache module for mod_wsgi, but will also install a Python module and admin script for starting up a standalone instance of Apache directly from the command line with an auto generated configuration. https://cleverdigi.weebly.com/huawei-mobile-partner-mac-os-x-download.html.
Let’s try it out
At this point I assume you have virtualenv and the XCode cli tools (
xcode-select --install
) installed (and of course the standard Apache from macOS). Everything else we will do together in the following steps.Setting up virtualenv
Let’s start by creating the directory for the application and setting up our virtual environment:
Now we activate our environment:
Installing mod_wsgi
Installing mod_wsgi is now easily done via pip:
Let’s see if it worked by launching the server:
By pointing your browser to http://localhost:8000/, you should be greeted by this page:
Looks good. Let’s stop the server with
ctrl-c
.Installing Flask and creating the web app
If you already have your Flask app, you can skip the next few commands, but for the sake of completeness, let’s install Flask and create a small sample web app (make sure you are still in your virtualenv):
Let’s create another directory to put the code of our web application in, and fire up an editor for creating the code file:
Paste this code (from the Quick Start tutorial) into your file:
Creating the wsgi script
To let the server know about our application, let’s create the wsgi script which we will later point to when starting the server.
Paste this code into the new file:
UPDATE: I initially set
sys.path.insert(0,'/your/path/my_app/')
in the snippet above. This is not needed, as the directory you run mod_wsgi-express setup-server
or mod_wsgi-express start-server
in is added to sys.path automatically. See thesethreetweets.Launching the server with the wsgi script
By going to http://localhost:8000/ you should now see the “Hello, World!” from our Flask app.

Doesn’t work for you? Didn’t work for me at first either as I had a typo in the code ?. Check out the error logs and you will see a hint of what might be wrong:

.Running the server in the background
Matlab 2014a download for mac. If you want to continue with your shell session, but leave the server running, you can use
nohup
.This will leave the server running, while you can continue working in the session (output will go to the file nohup.out). To bring it back to the foreground, use
fg
.UPDATE:Graham Dumpleton reached out to me and noted that the better way of running it in the background is by generating scripts via
setup-server
and then use apachectl to start/stop. So you might want to execute the following (as root) instead of using nohup

(feel free to change the port) https://genieclever461.weebly.com/download-imovie-themes-for-mac.html.
And then control the server state via: Is 3u tools safe to use.
Watching for changes
Macos Run Multi Flask Apps Online
When you develop your app and don’t want to reboot the server for each change, there is a convenient way of starting the server with the
--reload-on-changes
option. Now you can change your files and have the changes immediately served.More info
You can find more info about mod_wsgi (e.g. running it on a privileged port as root) on the PyPI page: mod_wsgi.
