Apache + Alias directories returning 404

Tamber-Krain · 09-27-2008, 11:32 AM

(I've banged my head against this problem for a coupla weeks now, and I'm finally admitting I'm stumped by it...)

I'm running Apache 2 (not sure which exact version, but I'm trying to get that now.) on my Gentoo server, and after a brief period of it being so badly misconfigured that it wouldn't serve documents at all, I have it working again.

Except for the Aliased directories, which I just get a 404 on each time I try to go to them.

My httpd.conf file is below:

I would very much appreciate being told where I've got this wrong, as it's beginning to annoy me... ^^;

I don't think you want the trailing slash or quotes, so try

Code:

Alias /icons /var/www/localhost/icons

instead of

Code:

Alias /icons/ "/var/www/localhost/icons"

Tamber-Krain · 09-28-2008, 07:07 AM

Hmm...
changed the Alias lines like you suggested, then restarted Apache. Unfortunately, this seems to have had no effect.

Code:

          Alias /icons /var/www/localhost/icons 
          Alias /error /var/www/localhost/error
          ScriptAlias /cgi-bin /var/www/localhost/cgi-bin/
          Alias /blog /var/www/localhost/wordpress
          Alias /gallery /var/www/localhost/gallery/
          Alias /wiki /var/www/localhost/wiki/

Do you know if the mod_alias test is being triggered?

Can you navigate to file://var/www/localhost/icons/index.html (subsititute a file that's there)?

Are you trying to navigate to httpd://localhost/blog/index.html or just httpd://localhost/blog? I don't see a DirectoryIndex entry anywhere

> Do you know if the mod_alias test is being triggered?

Not a clue, I'm afraid.

> Can you navigate to file://var/www/localhost/icons/index.html (subsititute a file that's there)?

I can, and I can view the file

> Are you trying to navigate to httpd://localhost/blog/index.html or just > httpd://localhost/blog? I don't see a DirectoryIndex entry anywhere

I was just trying to navigate to 'http://localhost/blog/', but I have tried 'http://localhost/blog/index.php' with the same result (404.)
Adding a DirectoryIndex did not help either.

EDIT: okay, I found why it didn't work, and now I feel really stupid.

Code:

LoadModule alias_module modules/mod_alias.so
<snip>
<IfModule mod_alias>

the mod_alias in the <IfModule> should be alias_module. I'm not sure why that just clicked now (It may have been the mention of the mod_alias test) but I'm glad it did.

I now present myself for ritual humiliation, as I deserve. :P

No - it's too easy to miss something that you later think is obvious - that's why I asked you the trigger question. It's too easy to see what you expect when you go over your own work (try proofreading something you've written - then give it to a friend/partner and see how many mistakes they find!)
