Running multiple flask application on apache server

Question

I have multiple flask application in var/www/html like var/www/html/website , var/www/html/summary , var/www/html/sentiment

Once I run all application successfully.

Then I added one more application for which I created conf file and restarted server.

After that all application stopped working, only var/www/html/sentiment opens.

I checked code in python, wsgi and conf file for other application is same as it is in sentiment.

Sentiment application code

flaskapp.py

from flask import Flask
app = Flask(__name__)

@app.route('/sentiment')
def hello_world():
  return 'Hello from Sentiment!'

if __name__ == '__main__':
  app.run()

flaskapp.wsgi

import sys
sys.path.insert(0, '/var/www/html/sentiment/')

from flaskapp import app as application

conf file - /etc/apache2/sites-available/sentiment.conf

<VirtualHost *:80>
                ServerName IP
                ServerAdmin admin@mywebsite.com
                WSGIScriptAlias / /var/www/html/sentiment/flaskapp.wsgi
                <Directory /var/www/html/sentiment/>
                        Order allow,deny
                        Allow from all
                </Directory>
                ErrorLog ${APACHE_LOG_DIR}/error.log
                LogLevel warn
                CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Summary application code flaskapp.y

from flask import Flask
app = Flask(__name__)

@app.route('/summary')
def hello_world():
  return 'Hello from Summary!'

if __name__ == '__main__':
  app.run()

flaskapp.wsgi

import sys
sys.path.insert(0, '/var/www/html/summary/')

from flaskapp import app as application

/etc/apache2/sites-available/summary.conf

<VirtualHost *:80>
                ServerName IP
                ServerAdmin admin@mywebsite.com
                WSGIScriptAlias / /var/www/html/summary/flaskapp.wsgi
                <Directory /var/www/html/summary/>
                        Order allow,deny
                        Allow from all
                </Directory>
                ErrorLog ${APACHE_LOG_DIR}/error.log
                LogLevel warn
                CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Still when I open ip/sentiment it works but ip/summary gives

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

Any suggestion for this?

Answer 1

The issue is with your WSGIScriptAlias name.

/ points to everything in the directory.

Give unique alias names to all applications.

Example:

Change / to /app1 for WSGIScriptAlias

Change / to /app2 for WSGIScriptAlias

in both the files.

Restart the server then.
