从www到非www的重定向不起作用

Question

I am trying to set a redirection from www to non-www page. I found plenty of instruction but I am missing something. Tracerout from www and non-www is identical and it's hitting my server so the DNS is save.

Here is my apache2 conf file:

<VirtualHost *:80>

    ServerAdmin webmaster@localhost
    ServerName mypage.com
    ServerAlias www.mypage.com
    DocumentRoot /var/www/mypage

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

    <Directory /var/www/mypage>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride All
            Order allow,deny
            allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    CustomLog ${APACHE_LOG_DIR}/access.log combined
    </VirtualHost>

and here is my .htaccess file:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
</IfModule>

Can anyone see what am I missing?

Answer 1

The reason your rule redirecting www to non-www probably isn't working is because it occurs after other rules with the L flag (which of course means to stop processing the rewrite rules). You might consider the following configuration, which puts that particular part first:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
    RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^ /index.php [L]
</IfModule>

I want to note a couple things here.

• The RewriteBase directive is kind of unnecessary here, unless that htaccess file isn't in the document root.
• The RewriteRule for non-www can use the %{REQUEST_URI} variable, and simply rewrite the entire request.
• Assuming you meant to rewrite the entire URI to /index.php on the last rule, you'd use the ^ character for that.
