wordpress urls not working with apache virtualhost - wordpress

Question

I have setup a apache virtual host using the below script -
<VirtualHost *:80>
ServerAdmin admin#example.com
ServerName nvoids.cu.cc
ServerAlias www.nvoids.cu.cc
DocumentRoot /var/www/html/blog
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Now this is working fine at this url - http://nvoids.cu.cc
which serves the pages from /var/www/html/blog
But the wordpress permalinks are not working for example
http://nvoids.cu.cc/hello/ throws a 404 page.
For that i tried changing the .htaccess file as follows -
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . blog/index.php [L]
</IfModule>
But its not working.

Answer 1

You need
AllowOverride All
In your VirtualHost directive to enable use of .htaccess files.

Answer 2

Is the following module enabled in your php.ini which should be uncommented? Do you see any error in your apache error log file?
LoadModule rewrite_module

Answer 3

As answered by Daniel the virtual server conf should be -
<VirtualHost *:80>
ServerAdmin admin#example.com
ServerName nvoids.cu.cc
ServerAlias www.nvoids.cu.cc
DocumentRoot /var/www/html/blog
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
<Directory /var/www/html/blog/>
AllowOverride All
allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
The .htaccess file as it is modified by wordpress -
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
