mod_wsgi-express: command not found

[yoshitaka okada]

hello :)

I am trying to upgrade a Django project on ubuntu.

However, now I am getting an Internal Server Error.

My environment is as follows

```

(venv) ubuntu@ik1-336-28225:/usr/src$ cat /etc/issue
Ubuntu 20.04.3 LTS \n \l

```

```

apachectl -v
  Server version: Apache/2.4.41 (Ubuntu)
  Server built:   2023-10-26T13:54:09

``` 

```

(venv) ubuntu@ik1-336-28225:/usr/src$ ls
  Python-3.11.7                    linux-headers-5.4.0-167-generic
  linux-headers-5.4.0-137          linux-headers-5.4.0-169
  linux-headers-5.4.0-137-generic  linux-headers-5.4.0-169-generic
  linux-headers-5.4.0-167          mod_wsgi-5.0.0

```

The libraries installed in the django project are as follows:

https://github.com/duri0214/portfolio/blob/master/requirements.txt

Now, Apparently there is a useful command called mod_wsgi-express.

The configure command probably worked.

No, but maybe it's not working... ?

```

(venv) ubuntu@ik1-336-28225:/usr/src/mod_wsgi-5.0.0$ sudo ./configure

```

make command doesn't work either.

```

(venv) ubuntu@ik1-336-28225:/usr/src$ make
make: *** No targets specified and no makefile found.  Stop.

```

And this command fails, so I'm at a loss as to where I'm going wrong. Is there anyone who can help?

```

(venv) ubuntu@ik1-336-28225:/usr/src$ mod_wsgi-express module-config
mod_wsgi-express: command not found

```

vi /etc/apache2/sites-enabled/000-default.conf

```

:

LoadModule wsgi_module modules/mod_wsgi.so

  :

```

Load module is probably fine.

If any information is missing, please let us know　:)

The mod_wsgi-express command is available when installing mod_wsgi using pip.

See:

and watch:

If you want to use configure/make/make install installation method rather than pip (which doesn't provide mod_wsgi-express) and manually configure Apache, then try running:

  ./configure --with=python=python3

By default it still looks for "python" which will only work if using Python 2.X or a virtual environment with Python 3.

Thank you master :)

The command now works.

```

(venv) rootik1-336-28225:/home/ubuntu# mod_wsgi-express module-config
LoadModule wsgi_module "/var/www/html/venv/lib/python3.11/site-packages/mod_wsgi/server/mod_wsgi-py311.cpython-311-x86_64-linux-gnu.so"
```

I replaced LOAD_MODULE with...

However, the web server that was previously working does not work at all even after restarting.

```

# vi /etc/apache2/sites-enabled/000-default.conf

```

If using pip install version of mod_wsgi, make sure that you haven't installed operating system package for mod_wsgi and have configuration using that still laying around. In other words, you should also have line:

LoadModule wsgi_module modules/mod_wsgi.so

That should be replaced with what "mod_wsgi-express module-config" output.

I can't comment any further if still got an issue without seeing the Apache configuration you used and what errors are appearing in any error logs.

Mean to say "In other words, you should NOT also have line"...

This is the apache configuration. It was working before I updated python to 3.11.

```

<VirtualHost *:80>

        # 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.

After deleting the log, when I restart and check the status, the following error appears.

```

The mod_wsgi operating system package may be installed.
I'll try resetting the OS once.

thank you

See comments below.

You should not have:

LoadModule wsgi_module modules/mod_wsgi.so

only the second one:

LoadModule wsgi_module /var/www/html/venv/lib/python3.11/site-packages/mod_wsgi/server/mod_wsgi-py311.cpython-311-x86_64-linux-gnu.so

The first one is trying to pick up system installed mod_wsgi and would take precedence, failing if it doesn't exist, and using wrong Python version or causing other problems if it did. So only use second LoadModule line.

WSGIScriptAlias / /var/www/html/portfolio/mysite/mysite/wsgi.py
WSGIPythonPath /var/www/html/portfolio/mysite

The WSGIPythonPath line here only affects embedded mode which you aren't using.

Remove WSGIPythonPath, but also add outside of the VirtualHost:

    WSGIRestrictEmbedded On

so that embedded mode is disabled.

WSGIPythonHome /var/www/html/venv

WSGIPythonHome is technically not needed when disabled embedded mode.
