Install WordPress in its own directory but permalink fails

I installed WordPress on EC2, located in /var/www/html/wordpress. I followed the WordPress guide to copy index.php and .htaccess to root which is /var/www/html, and modified index.php and setting in admin panel. It works pretty well if开发者_如何学Python I stick to only default link, such as: http://www.cubcanfly.com/?p=5, however other permalink options fails, actually all of the permalink options.

My .htaccess is

# 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>

in /etc/httpd/conf/httpd.conf

LoadModule rewrite_module modules/mod_rewrite.so

is NOT commented.

Thanks in advance

Finally I find the problem. It's the AllowOverride option in httpd.conf which is located in /etc/httpd/conf/httpd.conf, "sudo find / -name httpd.conf -print" can easily find it. I changed any AllowOverride NONE->ALL where i can find in the file. It just worked,even without doing any change to .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>

This .htaccess works on my host in which wordpress is installed in its own directory.

Thank you @adlawson @Will, without you, I couldn't find the problem.

http://codex.wordpress.org/Using_Permalinks this official guide is quite enough to use permalink even wordpress is installed in a sub directory.

Have a look at this post How does RewriteBase work in .htaccess

You need to change RewriteBase / to RewriteBase /wordpress

I did not need to edit RewriteBase in .htaccess. The problem really is in httpd configuration for EC2 machines.

My .htaccess -

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

In /etc/httpd/conf/httpd.conf -

<Directory />
    Options FollowSymLinks
    AllowOverride All
</Directory>

# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
#   Options FileInfo AuthConfig Limit
#
AllowOverride All
