can't enable mod_rewrite on local ubuntu apache server?

I have a base install of a LAMP server on my Ubuntu system, and I'm trying to get mod_rewrite working on that local server (the directory of the local site is localhost/project). I added this to my /etc/apache2/httpd.conf file, which was blank before I did so:

<Directory />
Options FollowSymLinks
AllowOverride All
Order deny,allow
Deny from all
Satisfy all
</Directory>

Code (markup):

and I ran this command to enable mod_rewrite:

sudo a2enmod rewrite

Code (markup):

I have this code in localhost/project/.htaccess, which works on another site on a shared server elsewhere:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond $1 !^(index\.php|ajax|css|error|img|js)
RewriteRule ^(.*)$ index.php?url=$1 [PT,L]
</IfModule>

Code (markup):

It's supposed to redirect everything except the listed directories to index.php, which is used as a front controller. However, if I type in http://localhost/project/<any other page> I get a 404 error.

Any ideas?
Thank you!

 

Try this rule just to be sure you don't have a rule problem:
RewriteEngine On
RewriteRule ^(google)$ /google2

If it redirects /google to /google2 you have a problem with your ruleset rather than with config
