Wsgi file does not import flaskapp

I have a Python Flask application that I want to run on a apache2(AWS EC2). This is my first time doing this so I have been using this source as a guide. However, my server keeps giving me the following errors and I do not know what went wrong. Please advise how I can solve this.

mod_wsgi (pid=5873): Failed to exec Python script file '/var/www/html/flaskapp/flaskapp.wsgi'.
[Tue Aug 17 21:04:26.331609 2021] [wsgi:error] [pid 5873:tid 140393656071936] [client 70.51.138.104:61053] mod_wsgi (pid=5873): Exception occurred processing WSGI script '/var/www/html/flaskapp/flaskapp.wsgi'.

My flask application path: /var/www/html/flaskapp/

Content of flaskapp folder:

application.py
utils.py
requirements.txt
flaskapp.wsgi

Content of flaskapp.wsgi:

#flaskapp.wsgi import sys sys.path.insert(0,'/var/www/html/flaskapp')

from flaskapp import app as application

Furthermore, I have also modified the /etc/apache2/sites-enabled/000-default.conf file:

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        WSGIDaemonProcess flaskapp threads=5
        WSGIScriptAlias / /var/www/html/flaskapp/flaskapp.wsgi

        <Directory flaskapp>
            WSGIProcessGroup flaskapp
            WSGIApplicationGroup %{GLOBAL}
            Order deny,allow
            Allow from all
        </Directory>

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

I have solve this problem by changing DocumentRoot /var/www/html to DocumentRoot /var/www/html/flaskapp in the /etc/apache2/sites-enabled/000-default.conf file.

I think you need to change the line:

from flaskapp import app as application

to

from application import app as application

As the error says Apache can't import the module, which I think has happened because in the tutorial you mentioned, the file containing the flask app is called flaskapp.py whereas your file is called application.py.

I would also consider changing the name of application.py to something more specific, like 'my_descriptive_app_name' if you are going to store it in the variable application.

I believe you may need to change your <Directory flaskapp to <Directory /var/www/html/flaskapp. It should be an absolute directory path or a wildcard, not a relative path.

Directory-path is either the full path to a directory, or a wild-card string using Unix shell-style matching.
