How to access localhost on Ubuntu for Windows?

I'm on Windows 10 Pro 64-bit, version 1709, OS Build 16299.125

I've installed the Ubuntu 16.04.3 LTS Linux Sub-system locally for Web Development purposes.

I've placed an info.php file into \var\www\html but when I attempt to access it at via my Browser in Windows, I receive the error:

"This page isn’t working is currently unable to handle this request. HTTP ERROR 500"

info.php has the following code in it:


// Show all information, defaults to INFO_ALL


If I access via my browser in Windows, I receive the Apache2 Ubuntu Default Page.

And that's it. Just trying to get this working. I've installed LAMP, Composer, Platform.sh CLI and that's it on this server thus far.

Edit Found an error log in \var\www\html called


Opened it and it says:

[15-Dec-2017 10:18:41 America/New_York] PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

[15-Dec-2017 10:18:41 America/New_York] PHP Fatal error: Unknown: Failed opening required '/var/www/html/info.php' (include_path='.:/usr/share/php') in Unknown on line 0

Not sure what that means. Any ideas?

Thank you.

Found out why this was happening. Ran:

$ sudo chmod -R 777 var

And that worked. I DO NOT RECOMMEND DOING THIS ON A PRODUCTION SYSTEM. This is a local Development System!

  • Check the permissions of each level of the directory tree for /var/www/html/info.php to make sure that whatever account Apache is running in has access. I was writing this comment when your answer appeared: it's unnecessarily drastic, and is definitely not recommended, as it will remove any extended attributes (SUID, etc). If you want to be so drastic, at least use ugo+rwx instead of 777 and log the changes with -v, so that you can undo them later with a bit of scripting on the log file. I doubt that you will need write access, nor to directories outside /var/html.
