How to check apache2 error logs at Github Actions failure?

Question

Body

Our github actions pipeline suddenly started to fail this morning and we're not sure why. We always tested the setup with a simple wget localhost, which now returns 500. Is there a way to reach or dump the apache error log to get more details?

    --2022-12-12 11:18:43--  http://localhost/
    Resolving localhost (localhost)... ::1, 127.0.0.1
    Connecting to localhost (localhost)|::1|:80... connected.
    HTTP request sent, awaiting response... 500 Internal Server Error
    2022-12-12 11:18:43 ERROR 500: Internal Server Error.

We're using the Ubuntu 18.04 image. Switching to Ubuntu 20.04 seems to break the connection to MySQL. Dunno if that matters for the error tho.

How are you running the web server? Exactly how to do it will depend on that, but in general writing the server's error log to standard output (so it appears in the workflow log) or uploading it as an artifact should work.

Edit: I found your Apache config. It seems to be lacking an ErrorLog directive. Add one and then use the file you configured. 🙂

In the end I did a try-catch around our index.php file to find the issue. It was a missing db driver.
